Fraser Cain824,747Super Science Circle for October, 2013I know it's been a while, so it's time for a new Super Science Circle - the October 2013 edition.In case you weren't aware, the Super Science Circle is a list of more than 400 people who are actively engaged on Google+ and regularly post about science and education. We've got journalists, scientists, even a few astronauts. The Super Science Circle should be your best response to anyone who tells you that Google+ is just a ghost town. If you love science, this circle will deliver the goods.If you know anyone who actively posts about science, please let me know and I'll add them to the list.2013-10-04 20:14:53415304682

Fraser Cain779,548Super Science Circle - May 2013 EditionNeed more science in your Google+? Well, here's all the science you can handle! Enjoy my latest, heavily curated edition of the Super Science Circle.Please share this circle... for Science!For the uninitiated, I maintain a circle of 450+ people who are active on Google+ and regularly post on Google+. In this circle you'll find scientists, journalists, astronauts, educators, and science enthusiasts. By importing this circle into your own circles, you'll immediately gain a vibrant and fascinating feed of amazing science stories.I recognize that it might be too much science, so I suggest you create a brand new temporary circle and evaluate the people in the circle. Only transfer the keepers to your permanent circles. Then, when I update the circle next month, rinse and repeat.Are you active on G+ and regularly post about science? +mention me and I'll check out your profile.Remember, please share this post2013-05-22 19:26:51456348088
Fraser Cain770,050Super Science Circle - April 2013 EditionIt's time for another sharing of my Super Science Circle. This is a collection of 400+ active people on Google+ who often post about science. If anyone tells you G+ is a ghost town (not that anyone does any more), get them to import this circle. PLEASE SHARE THIS CIRCLE... FOR SCIENCE!I have personally reviewed each and every person on this list, to make sure that they:1. Are active and engaged on Google+2. Regularly post science-related stories on Google+In this list you'll find scientists, journalists, researchers, professors, astronauts and general science enthusiasts. Not everyone in this list is going to be to your personal liking. So what you'll want to do is import the list into a temporary circle. Then move people over one by one into more permanent locations in your circles.I'm always looking for more people to add to the list, so if you know people who meet my criteria, feel free to nominate them.Again, please share the circle.

Fraser Cain759,117The Return of the Super Science CircleOkay, I'll admit, I made a mistake in retiring the Super Science Circle. I wasn't wrong; Communities are still the future and the best way to make friends here on Google+. But I realized that the Super Science Circle is simple and efficient way to get new people to see that Google+ isn't a ghost town.PLEASE SHARE THIS POST... FOR SCIENCE!When I was attending +ScienceOnline 2013, I must have helped dozens of people join Google+, and the first thing I had them do was import this circle. It's an invaluable tool for getting new people up to speed.So, I just did a complete refresh on the circle. I examined every single member and judged them according to my two-part criteria:1. Active in the last 30 days or so.2. Regularly post on scientific topics.If you know anyone who might make a good candidate for this circle, please let me know.As always, import this circle into a new, temporary circle, and then you can refresh it when I share a new version.DON'T FORGET TO SHARE THIS POST2013-03-19 22:39:3139967163160

Fraser Cain694,882The Final Super Science CircleWell, this is it, this is going to be the last posting of the Super Science Circle. Why? Communities, that's why. In case you didn't know, I've been maintaining my Super Science Circle from the very beginning of Google+. As soon as the feature to share circles was enabled, I was happy to share those circles around into Google. I did this because it was very difficult for people with related interests (science) to be able to find each other. I wanted new G+ users to realize this place isn't a ghost town; there are vibrant groups of people actively discussing scientific topics.But it was a hack. Each month took me almost an entire day to curate down the list of people, remove the inactive, and incorporate newly active people who often posted about science. And it was always imperfect. Some people got a massive boost in followers and engagement, while other, equally deserving people were left out.It was inelegant, inefficient and arbitrary.But now you can do this all on your own. You can go into any Community that matches your interest and instantly discover thousands of people who share your enthusiasm for a topic - just joining a Community will bring a trickle of posts about topics that interest you back into your stream. Keep your participation in the Community, or circle the most interesting people and harvest them back into your own stream.In the coming months, I'll be suggesting Communities you should join, instead of people you should circle. Thanks to everyone for using the shared circles and helping science get such a firm foothold here on Google+. Thanks to all the past and present members of the Super Science Circle for sharing such wonderful stuff.Science!2013-01-17 02:59:31420544084

Peter Smalley (Merkabah)10,068#sharedpubliccircles   #science  It's been a while since I shared a circle. Let's fix that, shall we? Here is my Circle of Science. Here you will find people who are practicing scientists, science writers, and science enthusiasts - and sometimes all three at once. There are biologists, chemists, physicists, microbiologists, food safety scientists, mathematicians, neurologists, astronomers and many other disciplines represented here. But regardless of their specialties they are intelligent, interested, and interesting.I won't call this a curated circle per se, but I can personally speak to quality of many of these individuals. Many of them are true gems.FOR SCIENCE!2012-11-26 17:29:545015211

Paul Christen0To the person that originally shared this circle with me (I forgot who...)Thank you.I am getting really tired of the glorification of stupid and the vilification of intelligence. I am afraid that its a systemic problem and frankly, I see no end in sight. Its similar to American politics in many ways."Well sure, professional athletes shouldn't rape women, but the dood can throw a football!" "Well, yeah, he ran a dog fighting ring, but let him play football and be a role model to  children anyway."We had a President, that was re-elected, that on any scale was a buffoon at best.The list goes on, and lets not forget the other side  of the  proverbial  coin, how often have we heard politicians talk about the "elite smart people"?Watch an episode or two of "Big Bang Theory". REALLY funny show, I refuse to watch it. I saw two episodes and both portrayed intelligence as negative.I heard an adult say (and I shit you not) "Kids don't need to learn what the mathematical median is, its useless knowledge, average is good enough." I tried to explain how it differs from average and how knowing the average and the median can help get a better view of the data (no point in going too deep) and got "nope, not needed".Whatever, I'm ranting and off the rails here.Do what you need to do to keep YOUR intelligence up and those around you, for the love  of Xenu, fight the good fight. Following this  circle  might help.2012-11-07 13:15:584135110

These are Games Masters, Writers, Artists, Podcaster, Bloggers,  Edition Warriors, LARPers or just plain old fans of Role Playing Games.If you choose to add this circle why not say hi?  Just toss all of them into a "new gamers" circle, send a message out to that introducing yourself and then move them into whatever sorting system you have. #circleshare  2012-11-01 02:44:25212302

Rumor Weed

Yesterday there was a flurry of news about a gamma ray burst (GRB) appearing in the Andromeda galaxy.  This would make it the closest observed gamma ray burst, which would be a boon for astronomers.  News of this discovery travelled fast, particularly on Twitter and other social networks.  Pretty soon a few news sites had picked up the story. But it turns out it wasn’t a gamma ray burst.  

It all started with a space telescope known as Swift.  Swift is designed to study gamma ray bursts, and one of its detectors is a wide field telescope known as the Burst Array Telescope (BAT).  The BAT is designed to look for bursts of high energy radiation from unknown sources.  If it detects one, it “triggers” and sends an alert so that other telescopes can be position to observe the event.  Gamma ray bursts can be short lived, so time is of the essence.

Yesterday there was a flurry of news about a gamma ray burst (GRB) appearing in the Andromeda galaxy.  This would make it the closest observed gamma ray burst, which would be a boon for astronomers.  News of this discovery travelled fast, particularly on Twitter and other social networks.  Pretty soon a few news sites had picked up the story. But it turns out it wasn’t a gamma ray burst.  

It all started with a space telescope known as Swift.  Swift is designed to study gamma ray bursts, and one of its detectors is a wide field telescope known as the Burst Array Telescope (BAT).  The BAT is designed to look for bursts of high energy radiation from unknown sources.  If it detects one, it “triggers” and sends an alert so that other telescopes can be position to observe the event.  Gamma ray bursts can be short lived, so time is of the essence.

Normally the level needed for the BAT to trigger is pretty high (6.5 sigma for you statisticians) so that it doesn’t cry wolf all the time (what are known as spurious events).  But the bar is set a bit lower if the energy burst seems to be from a nearby galaxy.  So Tuesday night (EDT) BAT detected a burst, and Swift’s x-ray telescope also observed a burst of x-rays.  The burst also happened to be in the direction of the Andromeda galaxy.  So it triggered and the alert went out.

Naturally, some of the astronomers working in this area of research use Twitter, and started tweeting about a possible GRB in Andromeda.  This was picked up by their fans and other astronomers, and the whole thing cascaded.  It turns out it was a known x-ray source, probably an x-ray binary.  So while it initially looked promising, it turned out to be a spurious event.  Sometimes this happens, and it is better to have the occasional false alarm rather than miss an important event.

Of course all of this played out in the social media circles, and its seems rather chaotic at the time. It also means sometimes things get reported as far more certain than they actually are.  If you actually look at what is being said, however, you’ll see something rather interesting.  If you go back and look at the comments, such as those tagged with #GRBM31 on Twitter, you’ll notice that the astronomers are pretty careful about saying things like “possible” GRB.  They spread the tentative news, and start looking for evidence to confirm or deny the event.  As they learn things from a clear source, they start tweeting that as well.  You’ll also note there is a great deal of excitement.

This is part of what makes science interesting.  Cool things happen, even if we later find out it isn’t as cool as we thought.___

Battle of the Bands

When light passes through gas and dust in the interstellar medium, some of the light is absorbed. Since the gas and dust only absorb certain wavelengths or colors of light, by by looking at these absorption bands we can determine the type of material that makes up the interstellar media.  Well, most of the time. It turns out there are a range of absorption bands that we haven’t been able to identify. They are known as diffuse interstellar bands.

One of the difficulties with these diffuse interstellar bands is that they don’t seem to match any known atoms or molecules. We know there are molecules that could form within the interstellar medium, but many of them haven’t been analyzed in the labs. Analyzing the line spectra of different compounds in a range of conditions such as vacuum and low temperatures is time consuming. Since it isn’t veryglamorou... more »

Analyzing the line spectra of different compounds in a range of conditions such as vacuum and low temperatures is time consuming. Since it isn’t very glamorous, it doesn’t tend to get much funding, and that limits our ability to analyze the bands.

Another challenge is that different bands can be stronger or weaker relative to each other. This means they are likely due to a range of processes.  There is some evidence that the strength of the bands correlates with the amount of dust in the region, so they are likely related to some kind of dust feature.  Right now one of the favored ideas is that they are due to some kind of larger hydrocarbon molecule. But as for the details, we just don’t know.

In case you missed it. +NASA has announced it has found the earth-size planet in a star's habitable zone, meaning the first true "Earth Twin" using data from Kepler. This is very exciting! Next step would be to see if it's possible to get a signal from the atmosphere's spectrum. That would reveal what the atmosphere is made of, and could possibly tell us if there is life (or possibility of life) in the planet. Great news!

Consume Mass Quantities

One of the big questions many people have about black holes is what happens when something enters one.  A recent Cosmos episode not withstanding, there is no reason to suspect that entering a black hole would take you to an alternate universe.  If you were to fall into a black hole, you would simply be in the black hole.  What happens to you after that depends upon the nature of quantum gravity, which we still don’t fully understand.

Of course all of this is according to general relativity.  While general relativity has been confirmed by multiple experiments, what evidence do we have of things falling into a black hole?  It turns out we have lots of broad evidence, and a bit of specific evidence.  The broad evidence comes from the observation of active galactic nuclei (AGN), which includes things like quasars, blazars and radio galaxies.  Thesehighly e... more »

Of course all of this is according to general relativity.  While general relativity has been confirmed by multiple experiments, what evidence do we have of things falling into a black hole?  It turns out we have lots of broad evidence, and a bit of specific evidence.  The broad evidence comes from the observation of active galactic nuclei (AGN), which includes things like quasars, blazars and radio galaxies.  These highly energetic objects are powered by active black holes.  Comparison of these objects to black hole models show strong agreement.  We know, for example, that black holes can develop an accretion disk of matter being consumed, as well as large jets of particles streaming from their poles.

We also have some evidence of black holes consuming individual stars. In 2011, the Pan-STARRS  telescope observed what initially appeared to be a supernova at the center of a galaxy about 2.7 billion light years away.  The spectrum of this burst indicated a large presence of helium, but no evidence of hydrogen.  This means it was not likely just some gas captured by the black hole (which would be a mix of helium and hydrogen), but rather due to the core of an old star (which is mostly helium) being captured.

Closer to home, we can observe a cloud of gas near the supermassive black hole in our own galaxy as it is gradually being torn apart.  In this case the cloud isn’t directly being consumed by the black hole, but the way in which the cloud is being torn apart has matched computer simulations of such close encounters.

So we actually have a good understanding of what happens to things as they fall into a black hole.  There are still questions yet to be answered, but our black hole models are rooted in observational evidence.

An asteroid with rings, detected using lightcurves, the same way we find planets. Might this be a way to find rings around exoplanets as well? :D

Put a Ring On It

Astronomers have found an asteroid with a ring system, and the results have been published Nature (pdf: http://goo.gl/kvPF2u). While this is the first discovery of a ring system about an asteroid, such a thing isn’t entirely unexpected.  We have known for a while that asteroids can have moons, for example.  But what’s particularly interesting is how they discovered these rings.

The asteroid in question is known as  Chariklo, a 130 kilometer wide object that orbits between the orbits of Saturn and Uranus.  It is the largest example of the Centaur group, which are likely Kuiper belt objects that were captured by the gravitational pull of the outer planets.  In the Summer of 2013, Chariklo passed in front of a dim, 12th-magnitude star as seen from parts of South America.  It is a phenomenon known as an occultation.

Such an event is a great opportunity to better determine the size and shape of an asteroid, so a team of astronomers dispersed through Brazil, Argentina, Uruguay and Chile made observations of the occultation.  Since each observation is made from a different vantage point, Chariklo’s occultation of the background star occurs at a slightly different orientation.  By combining these different observations the team could map the overall shape of the asteroid.

But what the team found was that from some vantage points the background star dimmed a couple times before being occulted by Chariklo, then dimmed a couple times after the occultation as well. Analysis of these pre and post dips makes it pretty clear that there are at least two rings around the asteroid.

Knowing that Chariklo has a ring system, the team was also able to determine a bit about the composition of the rings.  As Chariklo (or any other ringed object) orbits the Sun, there are times when the rings are seen more edge on, and times when we see more of the rings.  The team compared spectral observations of the asteroid between 1997 and 2008, and found that the asteroid gradually dimmed during that period.  The observation of water ice in the spectrum also faded during that period.  This would be consistent with a ring system containing ice (which is very reflective) gradually shifting to an edge-on orientation.

One of the more surprising aspects of the discovery is that the rings are so sharp and dense.  Typically a ring system would diffuse over time unless there are shepherd moons to keep the rings in order.  So it may be that Chariklo has not only a ring system, but a moon system as well.

To determine whether that is the case, it will likely take some high resolution imaging.  But that remains to be seen.

A great post on how science and "very little evidence" can cause media hype. Sob, we need better science-journalists...

On Dark Matter and Dinosaurs

Let me begin by saying there is no evidence that dark matter killed the dinosaurs.  None whatsoever.  Unfortunately the idea was posted on Nature’s blog, and from there it went to Scientific American and elsewhere.  The various social media took the story and it has spread like a prairie wildfire.  The actual preprint is much less sensational (and doesn’t mention dinosaurs) but it is still very speculative.  

The idea comes from the fact that the Sun does not follow a flat orbit around the galaxy.  Instead, its motion wobbles above and below the galactic plane, crossing the galactic plane every 35 million years.  This isn’t unusual, as lots of stars follow similar paths, but it has led some to speculate that perhaps this periodicity could explain periodic mass extinctions in the geologic record.

The problem is, there isn’t any strong evidence for cyclic mass extinctions.  Some analysis of the data has hinted at a pattern, but the correlation isn’t very strong.  Of course that hasn’t stopped people from proposing everything from companion stars to Nibiru to explain these periodic extinctions.  There been similar proposals that every time the Sun crosses the galactic plane the Oort cloud would be disrupted, causing comets to sweep into the inner solar system and bombard the Earth.

What’s new here is that the authors propose that dark matter within the plane of the galaxy is doing the disrupting.  As I wrote about last week, there is a hint of dark matter seen in gamma ray observations of the center of our galaxy.  One model that could account for these gamma rays is type of dark matter that would lie within the galactic plane.  So if this type of dark matter exists, and if it disrupts the Oort cloud when the Sun crosses the galactic plane, and if that caused comets to fling into the inner solar system and bombard the Earth, and if that bombardment caused periodic mass extinctions, then you should see some evidence in the geologic record.

So what evidence is there?  None.  Well, not quite none.  If you assume the model is true, and then look for a periodicity in the cratering record of Earth, you find that the cratering record agrees with the model about three times better that it agrees with random cratering.  Scientifically, that isn’t very convincing data.  It makes for a mildly interesting paper, but it’s mostly speculation at this point.

But Nature and several other websites have decided to take this speculative idea, add the word dinosaurs to the title, and imply that scientists are proposing dark matter killed the dinosaurs.  No one is proposing that.  It’s link-bait noise that makes the job of communicating real science all that more difficult.  So if you see one of these sensationalized titles, don’t share it on social media.  Tell your friends that share the articles that it’s speculative nonsense.  Hopefully we can drown this noise and get back to real science.

Because honestly, science is interesting enough without the hype.

A bit on something my project is about... 

Song of the Sun

There’s a song of the Sun.  It is produced by acoustic waves in the Sun’s interior, and the study of these waves is known as helioseismology.  

It turns out to be a very useful tool.  While light travels slowly through the Sun’s interior, taking thousands of years to travel from the Sun’s core to its surface, the solar interior is relatively transparent to acoustic waves, which means they can travel through the Sun at the speed of sound.

Because of this, sound waves in the Sun can be used to study the Sun’s interior, similar to the way ultrasound is used to see inside the human body.  The difference is that we can’t send sound waves through the Sun, but instead have to measure the natural sound waves that occur within the Sun.  We do this by measuring the oscillations of the Sun’s surface using the Doppler shift of spectral lines.

By analyzing these oscillations, we know that the interior of the Sun (known as the radiation zone because heat transfers radiantly in the core) rotates uniformly, while the outer layers (the convection zone) rotate differentially by latitude.  Acoustic analysis also gives us a measure of how the density and pressure of the Sun varies by depth, since the speed of sound within the Sun is affected by density and pressure.

There are even audio recordings of the Sun, where the solar oscillations have been speed up a bit and converted to sounds we can hear.  You can hear several of them here: http://goo.gl/bWWv

On Spectroscopy, the most important tool in modern science.

Rainbow Star

Spectroscopy is one of the most useful tools of modern astronomy.  With it we can identify the atomic and molecular composition of celestial objects, we can measure the relative motions of stars, and we can observe the expansion of the cosmos.  While early spectroscopes used prisms to break light into a spectrum, modern telescopic spectroscopes generally use a device known as a diffraction grating.

A prism is able to separate light into colors due to the fact that different colors bend at different angles when passing through a material.  You might remember this effect as the cause of chromatic aberration in telescopic lenses.  A diffraction grating uses the the wavelength of the light itself to create a spectrum.

Since light has properties of a wave, it spreads out in all directions from a source, just as ripples caused by dropping a stone in a pond.  Just as water waves can interfere and overlap, so can light waves.  The resulting effect that we see is due to the sum of all the light waves.  A diffraction grating is a fine grating of reflective surfaces, kind of like a reflective picket fence (but tiny).  When light strikes the diffraction grating, it is reflected from each different grating.  The light from each of those reflections spreads out in all directions, and they all interfere and overlap each other.  Because of the spacing of these gratings, different wavelengths of light are favored at different angles.  At each different angle of reflection we see a different wavelength.

There is a specific mathematical relation between the angle of reflection and the wavelength, so with a good diffraction grating we can get a very precise measure of the wavelength.  This makes it possible to make precision measurements of starlight and compare them to measurements done in the lab.  From this we can determine the properties of stars and galaxies.

A star has gone BOOM 12 mio light-years from here (so technically it went BOOM 12 mio years ago). It's quite a bright Supernova!

+John Green (Or somebody else at the awesome +Mental Floss or the all-knowing interwebz) Can you find a source on the Ptolomy / Shooting star story (#10). Our boss at the planetarium has made it a competition to find sources about shooting stars and comets in antiquity, since he has almost given up... So that would be nice :D

I am not a great fan of motivational videos. Most seem quite cheesy and superficial. +Beckie0 however has made a quite good collection of motivational quotes, that actually might get you out of bed, and do stuff. I hope it works with my thesis :P

Well, I love Terry Pratchett's take on why Santa (or the Hogfather) is important:

"All right," said Susan. "I'm not stupid. You're saying humans need... fantasies to make life bearable."

REALLY? AS IF IT WAS SOME KIND OF PINK PILL? NO. HUMANS NEED FANTASY TO BE HUMAN. TO BE THE PLACE WHERE THE FALLING ANGEL MEETS THE RISING APE.

"Tooth fairies? Hogfathers? Little—"

YES. AS PRACTICE. YOU HAVE TO START OUT LEARNING TO BELIEVE THE LITTLE LIES.

"So we can believe the big ones?"

YES. JUSTICE. MERCY. DUTY. THAT SORT OF THING.

"They're not the same at all!"

YOU THINK SO? THEN TAKE THE UNIVERSE AND GRIND IT DOWN TO THE FINEST POWDER AND SIEVE IT THROUGH THE FINEST SIEVE AND THEN SHOW ME ONE ATOM OF JUSTICE, ONE MOLECULE OF MERCY. AND YET—Death waved a hand.AND... more »

Google celebrates Tycho Brahes birthday with a Doodle today. Very nice. They even got his copper nose (Tycho's nose was chopped off during a duel, and he wore a copper nose for most his life. He also had one of silver, for party occasions). He made the first astronomic atlas since Hipparchus in ancient Greece, invented quite some instruments (and especially how to construct precise rulers) he was one of the first to use averages to gather better results, discovered that the heavens are not unchangeable (he saw what he thought was the birth of a new star. In reality a Supernova"  and coined what is known as the first rule of physics "By looking down I see up, and by looking up I see down" or "The laws of physics are universal"

Wormholes, Entanglement and Holograms, Oh My!

You may have heard about how quantum particles are wormholes, or holographic somethings.  Whatever.  It’s quantum wormhole things that, well, do something.  So what’s all the hype really about?

It all stems from a recent paper in Physical Review Letters (paywalled, but arxiv to the rescue: http://goo.gl/Z0gez3) dealing with entangled particles and their connection of their holographic duals to wormhole geometries.  So let’s start with a little background.

Entanglement is a well-known property of quantum mechanics.  It is perhaps most famously demonstrated through the Einstein-Podolsky-Rosen (EPR) experiment.  Suppose we have a mischievous mutual friend.  She decides to prank us by sending sending each of us one member of a pair of gloves.  She packs each glove in a box and mails one to each of us.  We find out about the prank, so we both know that we’re getting one glove of a pair.  But until either of us open our respective box, neither of us know which glove we have.  Once the box arrives at your door, you open it up, and find you have the left glove.  At that moment you know I must have the right glove.  

This is the basic idea of the EPR experiment.  For gloves it isn’t a big deal, because from the get-go the left glove was heading your way.  You just didn’t know you were getting the left glove.  That’s because gloves are not quantum things.  In the quantum regime, things get much more strange.  In quantum theory, things can be in an indefinite state until you observe them.  It would be as if our boxes contained a pair of something (gloves, shoes, salt and pepper shakers, etc.) but it is impossible to know what specific something until one of us opens their box.  

In quantum theory we would say the boxes contain a superposition of possible things, and the outcome only becomes definite when the outcome is observed.  Now even though you can’t know what specific object you have, you know that I must have its pair.  So if you open the box to find a red right shoe, you know immediately that I must have a red left shoe.  We both know this without opening the box, so we can say that the outcomes of opening our boxes are entangled.  Knowing the contents of one box tells us the contents of the other.  We’ve actually done this experiment with photons, atoms and the like, and it really works.  

Of course this is really hard to wrap your head around.  If I’m thousands of miles away from you, and I open my box to find a salt shaker, I know you must have a pepper shaker.  But your box couldn’t have known that until I opened the box.  How is that possible?  How can the opening of my box instantly affect your box thousands of miles away?  Do the boxes communicate faster than light? (No.)  Is there some secret (hidden variable) so that the boxes know what they will become when observed? (No.)  That is part of what makes entanglement so strange, and the EPR experiment so popular.  The one thing we can say is that entanglement is a very real physical effect in quantum mechanics.  There isn’t anything magical going on, just something we humans find strange.

Wormholes come from general relativity.  Unlike entanglement, there is no experimental evidence for wormholes.  Instead, they are a hypothetical connection between two locations in space.  Normally when people think of wormholes, they think of something out of science fiction (http://goo.gl/nz5SV2) where people use wormholes to travel to distant stars, but the hypothetical wormholes in general relativity aren’t traversible, nor do they have to be large.

This particular paper is looking at how there might be a connection between wormholes and quantum particles.  This idea isn’t new, in fact the idea that fundamental particles could be wormholes dates back to the 1950s, when John Wheeler proposed a model known as geometrodynamics, where everything was empty space and charged particles were the mouths of wormholes.  Wheeler was an excellent physicist known for coming up with a lot of wild ideas, some of which worked, and some of which didn’t.  In the case of geometrodynamics, it never really worked, and after a while interest faded.

But with the rise of string theory, different versions of the idea have gained some popularity.  Hence this new paper.  What the authors did was to look at a specific case of the EPR experiment, dealing with two quark particles.  What they were able to show is that the entangled quarks can be described in two ways.  The first is the standard way in which entanglement is described in quantum theory, but the second (dual) way is as two particles connected by a wormhole.  Both of these descriptions are equivalent.  

Does this mean that entangled particles are wormholes?  No.  What it means is that there is an interesting connection between the mathematics of entanglement and the mathematics of quantum wormholes.  Just to be clear, this has nothing to do with any new experimental evidence.   But it is interesting, because it shows a connection between quantum entanglement and general relativity, and that may lead the way toward a better understanding of quantum gravity.

Hello followers. An Italian friend of mine (an other astrophysicist as a matter of fact) is apparently also a great photographer. He has joined a competition where he needs as many votes as possible. So, look at the images, and vote if you like. I especially like the macro-photos and the By-night city photos.
