It's not very likely that you'll be around to witness the end of time for yourself, but physicists have helpfully devised an experiment to simulate it using metamaterials.
The hopes of going back in time and visiting the jurassic era to escape a T-Rex and warping into the future to save the world from Skynet will never happen. Chinese physicists have just proved that time traveling is out of the realm of possibility (at least in this universe).
After sorting through some 500,000,000,000,000 fatal and extremely messy accidents between protons and anti-protons, scientists at Fermilab have picked out 25 which prove the existence of a previously undetected particle: the neutral Xi-sub-b. And it's full of strange.
Those greedy scientists, they just can't learn to share. Instead of going out and getting two little glass spheres, they're trying to use a trick of quantum mechanics to take one little glass sphere and make it exist in two places at the same time.
The Large Hadron Collider over in Europe may be making all the physics headlines as of late, but the U.S. Department of Energy is trying to scrape together between one and two billion dollars to build a particle physics lab deep in an abandoned gold mine underneath South Dakota.
They call it "cartoon physics" for a reason, that reason being that most of the "physics" that goes on in cartoons is not physically possible. But what happens if you run the numbers and then try to rationalize it all? Here's a hint: it involves lots of things being secretly made from dark matter along with copious amounts of invisible thrusters.
You've heard of black holes: those rips in spacetime that suck up matter into oblivion. Now scientists are proposing that we've seen evidence for the opposite of black holes, or white holes, which spew out matter into our universe instead.
Scientists at CERN have announced that they've been able to trap 309 atoms of antihydrogen for over 15 minutes. This is long enough that soon, they'll be able to figure out whether antimatter obeys the law of gravity, or whether it's repelled by normal matter and falls "up" instead. It would be antigravity, for real.
Here's what it looks like when two particles share the same properties — even if they're separated in space and time. Physicists S. Jay Olson and Timothy C. Ralph of Australia's University of Queensland explain further here....
Back when I took physics in school, it was all about studying the 'laws' discovered by a bunch of old dead guys, and crunching lots of numbers. If only we had this type of visualization to make things more interesting.
