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.

"It is my understanding that the universe is saddle-shaped. My question is, at the time of the big bang, why didn’t everything expand in all directions equally, causing a spherical shaped universe?"

Sorry, Simpsons fans, Homer's theory of a donut-shaped Universe might be intriguing to Stephen Hawking, but it's time to listen to what the evidence says! Find out how the Universe is shaped on this week's Ask Ethan.

“In 1947, a radio source towards the center of our galaxy was discovered: the strongest outside of the Solar System, Cassiopeia A. What caused it? A supernova dating back to the 17th century — the most recent one in our galaxy — with a massive black hole left behind.”

Located in the plane of our Milky Way galaxy, the light was obscured for skywatchers on Earth, but thanks to a suite of great, space-based observatories (Hubble, Spitzer, and Chandra), we’ve been able to piece together exactly what occurred. Not only that, but observations of a “light-echo,” or reflected light off of the nearby gas, has allowed us to see the light from this explosion centuries later, and learn exactly how it happened.

"But if we can take advantage of the time dilation effect of muons, the ultimate machine may very well be a muon collider, as the factor of 206 in mass increase over an electron means that it would lose two billion times less energy than an electron would with every pass around the ring."

A pipe dream and the stuff of science fiction just 20 years ago, recent advances have this on the brink of becoming reality, with a legitimate possibility that a muon-antimuon collider will be the LHC’s successor.

"Does a black hole have a shape? Is there a front and back or side view? Does it look the same from all vantage points?"

When you think about a black hole, you very likely think about a large amount of mass, pulled towards a central location by the tremendous force of gravity. While black holes themselves may be perfectly spherical (or for rotating black holes, almost perfectly spherical), there are important physical cases that can cause them to look tremendously asymmetrical, including the possession of an accretion disk and, in the most extreme case, a merger with another black hole.

"Eventually all reachable stars in our region will either be burned-out stellar relics, neutron stars (ultradense stellar cores), or black holes (the ultimate state of collapse for massive stars, resulting in gravitational wells from which nothing can escape directly, not even light). Black holes slowly release their energy through the process of Hawking radiation, so they are hardly immortal. Meanwhile space will continue to expand and cool, serving as a kind of vast deep freezer full of the frozen corpses of once shining stars."

Even while we head towards the heat death of the Universe, it may be possible for intelligence in an artificial form to continue for an extraordinarily long time: possibly for as long as a googol years. But, that's still not quite forever. Eventually, it all must end, as +Paul Halpern  explains.

"This Friday marks the 96th anniversary of one of the most important historical events in all of science. We can look back at all the time that’s passed, and find that every single prediction of Einstein’s gravity that’s ever been tested — from gravitational lensing to binary pulsar decay to time dilation in a gravitational field — has confirmed General Relativity as perhaps the most successful physical theory of all-time. It all goes back to one fateful day, nearly a century ago, and our understanding of the Universe has never been the same since."

That time when, after 200+ years, we changed the laws of gravity. THAT'S a throwback thursday/flashback friday!

"Sally Ride wasn’t the first US woman to become an astronaut to me. She was an astronaut, a teacher, a scientist, a writer, and a role model who happened to be a woman.

Sally Ride didn’t teach me that women can be anything they want to, just like men can; Sally Ride helped me to grow up in a world where the notion that you couldn’t be anything you wanted because of who you intrinsically are is absurd, and demonstrably untrue."

Sally Ride left behind a legacy that everyone can grow up to realize their dreams, and become anything they have the desire and capabilities of becoming. Come see how the world -- and everyone growing up in it since -- has changed forever, thanks to her.

"On Earth, the combined effects of the Moon and Sun cause modest tides, raising and lowering the oceans by ~1 meter at a time, and causing the crust to bulge and shrink by millimeters or centimeters with each rotation. But on Io, the tidal forces due to Jupiter are absolutely tremendous: some 10,000 times as strong as we experience here on Earth. And this is significant enough to literally rip Io’s surface apart with practically every orbit of the moon around its shepherding planet."

Every rocky world in the solar system is covered with craters. But while the ones on Mercury and the Moon might be many billions of years old, the craters on Earth are much younger, due to volcanism, plate tectonics and general geological activity.

"How likely is it that the LHC will provide this support for string theory you want to know? Let me ask you in return: If you had a crush on Susy and she said she might come by after work, around 8pm, but she hasn’t shown up by 10, what are the chances she’ll be there by 10:05? Right. And them extra dimensions? Well, they never said they would come by, you just couldn’t exclude they wouldn’t."

The Large Hadron Collider has just been upgraded, and is now making the highest energy collisions of any human-made machine ever. But even at 13 TeV, what are the prospects for testing String Theory, considering that the string energy scale should be up at around 10^19 GeV or so? Surprisingly, there are a number of phenomenological consequences that should emerge, and looking at what we've seen so far, they may disfavor String Theory after all.

"If we use the standard Copenhagen interpretation of quantum theory, an observation of one state “collapses the wavefunction” of the entangled system. This collapse occurs instantly, and thus is clearly faster than the speed of light. But this again doesn’t violate relativity, since information about the system doesn’t travel faster than light. In other words, your knowledge about the measurements the other observer will make in no way gives information to anyone faster than light; the observations they can make will all be unaltered from their indeterminate state until they receive information from you about what’s in their entangled system."

"But if the eyes of our telescopes on Earth were especially keen, the exact moments of opposition — where the Sun is directly opposite to Saturn in the skies — would have brought on a spectacular phenomenon: an intense brightening at one particular point, known as the opposition effect."

Saturn was just at opposition this past Saturday, appearing bigger, brighter and less shadowed than at any other time of the year. But have you ever heard of the 'opposition effect'? One of the coolest optical phenomena ever, coming to us courtesy of Cassini!

“But this eruption is special, having been going on for hundreds of millions of years, due to the size of the eruption that’s many millions of light years across. If it were caused by accreting matter, it would have had to accrete nearly a billion solar masses worth of material. The combined radio (VLA), visible (Hubble) and X-ray (Chandra) data suggest another interpretation: an ultramassive black hole in excess of 10^10 solar masses powers the outburst.”

What’s causing this monstrosity at the heart of MS 0735.6+7421? Come find out on Mostly Mute Monday.

“There are 12 men on an island. 11 weigh exactly the same amount, but one of them is slightly lighter or heavier. You must figure out which. The island has no escapes, but there is a see-saw. The exciting catch? You can only use it three times.”

It was the toughest brain teaser of the season on television, resulting in a hilarious #nerdfail for detective Santiago. Here's not just the solution, but all possible solutions, worked out in illustrated form.

"I really did get a lot of comments like this (I mean, you can go read them), mostly from people justifying asteroid defense by the “risk assessment” viewpoint argument as follows:

* If we get hit by a civilization-killer asteroid, everything is gone. It’s the biggest catastrophe ever, it’s game over for all of humanity, it’s a hundred million year setback for evolution, and it’s literally the worst-case scenario.
* Therefore, if there’s even a finite probability of it happening, finite probability multiplied by infinite value consequence equals infinite importance, and therefore we should stop it.

But I would dispute both of those charges."

In the beginning, there was light. Then it went away. It took 50-to-100 million years for the Universe to make that mistake again; here's the science of what happened in the meantime.

Right now, we can already be sure of some things that it isn’t, but the coming months will shed so much light — at such improved resolution — on what’s really causing this most mysterious of features.

"As the comet nears the Sun in its orbit, the increased solar radiation vaporizes the ices on its surface, causing ionization, surface disintegration and the development of cometary tails. As it approaches perihelion, its speed increases from just a few km/s all the way up to many hundreds, with the longest tails extending for distances of 500 million kilometers. The various colors come from atomic transitions of various atoms and molecules, such as the green coma coming from the excited diatomic carbon molecule and blue coming from cyanogen."

Because we look back in time when seeing distant objects, the CMB is then logically the most distant “thing” that we can see. This would suggest that the CMB is the end of the universe, but we know that isn’t true. Space goes on infinitely, as far as we know, and we know we haven’t seen its edge. So, where is the CMB that we imaged if not at the edge of the universe?"

When it comes to the farthest thing we can see in the Universe, that’s the Cosmic Microwave Background, or the leftover glow from the Big Bang, emitted when the Universe was a mere 380,000 years old. But what, exactly, does this mean? Does it mean that we’re seeing the “edge” of the Universe? Does it mean that there’s nothing to see, farther back beyond it?Does it mean that... more »

Does it mean that, as time goes on, we’re going to be able to see farther back in time and space? The answers are no, no, and yes, respectively. If we want to see farther than ever before, we've got two options: either wait for more time to pass, or get moving and build that cosmic neutrino background detector.___

"Of course, no one wants this to be a problem. No one wants a world where our own backyard — where we work hard to send the message that science, and the wonders and joys of learning about the Universe, is for everyone — isn’t a welcoming, accepting place for everyone who wants that knowledge (and to share it) themselves."

If you've ever thought that women maybe aren't treated the same as men in science, but didn't know what you could do to help everyone get the treatment they deserve, here are some things you may want to consider. Science ought to be for everyone; let's make sure it actually is!

"It’s only the presence of these massive dark matter halos, surrounding our galaxies, that allow the carbon-based life that took hold on Earth — or a planet like Earth, for that matter — to even be a possibility within our Universe. As we’ve come to understand what makes up our Universe and how it came to be the way it is, we’re left with one inescapable conclusion: dark matter is absolutely necessary for the origin of life."

Without dark matter — a substance that doesn’t interact in any (yet) measurable, non-gravitational way with anything else (or even itself) in the Universe — life as we know it would be unable to exist. The gravitation from dark matter is the only thing keeping supernova ejecta from escaping from our galaxy, and enabling heavy elements to participate in later generations of stars, planets, and biochemical reactions.

"Currently orbiting at a distance of 13,600 kilometers off of the asteroid’s surface, or some forty times more distant than the International Space Station is from Earth’s surface, Dawn will descend over the coming months, mapping out Ceres with a variety of instruments, and learning the elemental composition of this material. Sure, the images Dawn has taken so far are spectacular, but there’s so much more to come."

The greatest mystery so far are two bright white spots at the bottom of a deep crater, brighter and more reflective than anything else on the planet's surface. Right now, three leading possibilities for the origin of these features exist, with Dawn possessing the capabilities to teach us which one (if any) is correct, hopefully by the end of the year!

We can learn exactly where we came from, where-and-what we are and where we’re headed. And that’s something truly remarkable, indeed."

“In 1947, a radio source towards the center of our galaxy was discovered: the strongest outside of the Solar System, Cassiopeia A. What caused it? A supernova dating back to the 17th century — the most recent one in our galaxy — with a massive black hole left behind.”

Located in the plane of our Milky Way galaxy, the light was obscured for skywatchers on Earth, but thanks to a suite of great, space-based observatories (Hubble, Spitzer, and Chandra), we’ve been able to piece together exactly what occurred. Not only that, but observations of a “light-echo,” or reflected light off of the nearby gas, has allowed us to see the light from this explosion centuries later, and learn exactly how it happened.

"Thankfully, the world of LEGO is an interchangeable place, where you can truly run wild with your imagination. If the LEGO movie teaches us nothing else, it’s that we don’t need to be bound by the rules of the LEGO suggestions, and that just because you’ve gone and invested in building a LEGO Death Star doesn’t mean it needs to be an exact Death Star."

What happened to the Death Star when the war ended? Surely, as we all learned from the party on Endor, it was nothing but clear skies and friendship ahead. But what about the surplus parts? Steve Price has got it all figured out: they were taken over by the LEGO Friends Girls, and used to construct the opposite of the Death Star, The Friends Star!

"The light from EGS-zs8–1 comes to us from some 13.1 billion years ago, from when the Universe was a mere 660 million years old. But here’s the kicker: when we calculate the distance to this galaxy, we find it to be 29 billion light years away. In other words, not only is this galaxy farther away than the Universe’s age, it’s much farther away!"

"You see, there might not be a limit to the energies we can give to protons in the Universe: you can accelerate charged particles using magnetic fields, and the largest, most active black holes in the Universe could give rise to protons with energies even greater than the ones we’ve observed!

But they have to travel through the Universe to reach us, and the Universe — even in the emptiness of deep space — isn’t completely empty. Instead, it’s filled with large amounts of cold, low-energy radiation: the cosmic microwave background!"

The most energetic particles we find are up to ten million times greater than the energies we make at the LHC, but no greater than that. Come find out why!

"So far, all of its predictions of what should be potentially observable in our Universe — supersymmetry, extra dimensions, new particles, new decays — have failed to be borne out. Every observation is consistent with null results: no string theory. But perhaps there are clever ways to discover a way that string theory could result in an observable effect that isn’t predicted by standard physics in the real Universe."

You might think that, when it comes to finding the most distant objects in the Universe, all we need is a good telescope, to leave the shutter open, and wait. As we accumulate more and more photons, we’re bound to find the most distant, faint objects out there. Sure, Hubble just broke its own cosmic distance record, but it's certainly not the most distant. Thinking so misses an important fact: the Universe is expanding! And with that expansion, the wavelength of the light we can see gets redshifted.

“Despite gathering twice as much light (resulting in 41% deeper viewing), the eXtreme Deep Field found only a few percent more additional galaxies to the Ultra Deep Field. Rather than being a signature that we’re seeing all the galaxies that there are — 5,500 of them in a region comprising just 1/32,000,000th of the entire sky — this is a signal that these images are reaching the limit of what Hubble can see. To go farther, we’ll need an infrared observatory: exactly what the James Webb Space Telescope will deliver to us in 2018. In the meantime, these images teach us there are at least 170,000,000,000 galaxies in the entire observable Universe.”

With double the exposure time in the same region as the Ultra Deep Field, we’ve set the most robust lower limit on the number of galaxies in the Universe, and learned what it will take to find the rest.

I’m sorry to say that in my opinion the fact that they went ahead with demonstrably incorrect and over-hyped claims reflects very poorly on them. Publicity in news media who know nothing about physics is one thing, but it is much more worrying that such pseudo-scientific claims receive prominence on your own well-informed blog too."

In a rare edition of comments of the week, I have to eat some crow for highlighting a result that was refuted. Thankfully, the author of the refutation dropped by Starts With A Bang, and now I get to highlight their work, and the accurate science of the coldest spot in the Universe!

"According to physics, if you can use a running start to get an extra few miles-per-hour (let’s say 5 miles-per-hour) onto your club head speed, that should translate to an extra 8 miles-per-hour for the initial speed of your ball. What does that mean for distance?

You need to take into account air resistance, trajectory, and a whole host of other things. Thankfully, these things are well-understood, so let’s get right to the results! According to realistic physics, we’re talking maybe an extra 10% longer off the tee, which isn’t too shabby!"

It was an idea made famous by the movie Happy Gilmore, but the physics behind it is actually sound: getting a running start, even a slow one, should theoretically be able to improve your driving distance by about 10% off the tee. But there's a big different between physics-in-theory and physics-and-physiology-in-practice, atleast, ... more »

But there's a big different between physics-in-theory and physics-and-physiology-in-practice, at least, in many cases. This time, however, they line up beautifully, as a running start really can help your golf game!___

"To make it as a scientist, you have to be passionate about relentlessly pursuing the truth the Universe tells us about itself, no matter where it leads you. You have to be willing to challenge your assumptions, to test them, and to build off of the quality work of others. Your results must be independently reproducible, and your conclusions must be consistent with the full suite of results that are out there, both in your sub-field and in related fields.

If you want to construct an accurate picture of what governs the Universe, you need to build on all that we’ve learned up to this point. And when we say “scientific consensus,” that’s what we’re talking about: things we’ve already learned, and the solid foundation for where we go from here."

You might have grown up believing that doing something yourself is the only way to ensure it gets done correctly. But when it comes to science, not only is that not the case at all, but a scientific consensus isn’t the conclusion, but rather the starting point.___

"Without the additional gravitation of a massive dark matter halo surrounding a galaxy, the overwhelming amount of material ejected from a supernova would escape from galaxies and wind up floating freely in the intergalactic medium, never to become incorporated into future generations of star systems. In a Universe without dark matter, we’d still have stars and galaxies, but the only planets would be gas giant worlds, with no rocky ones, no liquid water, and insufficient ingredients for life as we know it."

Dark matter is necessary to explain the motions of stars, galaxies and the formation of structure in the Universe, but most surprisingly is how its presence and abundance is essential to the existence of life in the Universe.

My latest for Forbes!
