    Physics Students Explore Possibility of Gravity‘s Space Debris Incident Becoming An Actual Problem

    We all know that Gravity is a work of fiction and the Hubble telescope didn't really get hit with debris from a defunct satellite. As students from the University of Leister pointed out in a recent paper, though, there is a defunct satellite that could pose a threat to current real-life space missions: Envisat.

    Kittens Play With A Newton’s Cradle And Discover Physics, It’s A CuteScienceSplosion

    Cats meet science in this video clearly made with Geekosystem's audience in mind! Watch three kitties (named Panda, Pikachu, and Pavel, because this wasn't cute enough already) play around with a Newton's Cradle, and discover the wonders of physics. This transfers adorableness via internet like energy through a Cradle.

    Hawk-Eye,The Line-Calling Sports Camera, Might Not Be As Accurate As We All Thought

    Today we learned two things: one, that the device used to make  line-calls in tennis is very appropriately called "Hawk-Eye." Two, it's probably made a whole bunch of bad calls that we weren't aware of until just now. Whoops. Sorry, Barton. How 'bout we give you, like, an extra ten seconds of screen time in Avengers 2 to make up for it?

    Several Means of Real Time Travel Explained by MinutePhysics [Video]

    Time travel is as real as the fact that you are now farther into the future than when you started reading this sentence. That's boring time travel, though, as MinutePhysics explains in a new video on real ways that time passes differently. The effects may be negligible in every day life, but time travel is all around us—like the Force.

    Peter W. Higgs and François Englert Win Nobel Prize in Physics for the Higgs Boson

    The 2013 Nobel Prize in Physics is being awarded to Peter W. Higgs and François Englert for their work on theorizing the Higgs boson particle. The Higgs boson has been in the news a lot over the last few years, but Higgs and Englert's work theorizing it took place in the 1960's. It's about time, Nobel Committee.

    Teleportation Might Be Possible, If You Don’t Mind Waiting 4 Quadrillion Years

    Your dreams of being beamed up by Scotty are about to be crushed, Trekkers. Physics students at the University of Leicester have discovered that, even if teleportation were possible, the amount of time it would take to download and re-upload a human brain would be equivalent to over 4 quadrillion years. Scotty is not waiting around for that.

    Relax, MIT and Harvard Scientists Did Not Build a Lightsaber

    A team of physicists from MIT and Harvard have created a new form of matter by binding photons into molecules. The team compared the way these new molecules interact to lightsabers, and the Internet went bonkers. Pump the brakes, everyone. They have not created a lightsaber. Here's what happened.

    High Energy Regions in Radiation Belt Around Earth Speed Up Electrons to Nearly the Speed of Light

    We've got good news for anyone who's ever dreamed of taking a trip to CERN to see how a giant particle accelerator operates -- you can save yourself a plane ticket. As it turns out, the Earth itself is surrounded by a radiation belt that contains regions of energy that act like particle accelerators

    Antimatter Matters, the Quantum Physics Board Game, Makes Assembling Atoms Into a Competition

    I'm not a big board game player, nor am I particularly well-versed in the ways of subatomic particles -- and I'm sure that probably goes for a good number of you as well. However, Portland-based game company Elbowfish wants to change all that. Their Kickstarter campaign to fund a new physics-based board game, Antimatter Matters, has just three days left to go and is so close to getting funded that I can almost taste the quarks. Needless to say, all of the flavors are delicious, not to mention educational!

    The Wolverine Train Fight Clip Drops, Defies All Possible Laws of Physics [Video]

    Now, I'm no expert on what it's like to fight somebody on top of a speeding bullet train in Japan, but I kind of feel like something's sort of wrong with the way that Logan does it in this recently dropped clip from The Wolverine. It's badass and all, for sure, but did that one guy really have enough of his own momentum to fly backwards like that if the train is moving at a constant velocity? Aw, heck, watch the video first and then decide for yourself.

    I Want One! Physicists Create Desktop-Sized Antimatter Gun

    hose of you looking to begin a career in supervillainy will want to take note of this story -- researchers working at the University of Michigan have succeeded in building an antimatter gun small enough that it can rest on a standard desktop. And, when it's not resting , it can fire brief blasts of electrons and their antimatter counterpart, positrons. World leaders can sleep easy, though, despite the fact that desktop antimatter guns are now a thing that exist. Rather than bringing cities to their knees, the team of researchers behind the project want to use it to learn more about the strange physics of black holes, which emit bursts of positrons and electrons, albeit on a much grander scale than the University of Michigan antimatter gun.

    Four Quarks Good, Two Quarks Bad: Scientists Detect New Kind of Subatomic Particle

    Researchers at two different particle accelerators have discovered what looks like evidence of the existence of particles composed of four quarks. Don't know what that means? Don't worry, the scientists involved aren't quite sure what to think yet, either. They don't even know if the results are truly new particles of just misleading blips in mountains of data. One thing  is for sure, though -- if you thought we were done talking about particle physics once we found the Higgs boson, guess again.

    How Do You Turn Sound Into Light? Turns Out, We Don’t Exactly Know

    When bubbles underwater cavitate -- collapse under negative pressure -- the result is a shockwave of sound like the one that mantis shrimps use to blast their prey. That shockwave isn't the only result though, as it's sometimes accompanied by another release of energy in the form of a flash of light. These transformations of sound into light -- episodes of sonoluminescence -- remain ill-understood, but leave it to the folks at Minute Physics to offer as clear a breakdown of what we do know about the phenomenon as you're likely to find in this video.

    A Brief Guide to the Beginning of the Universe [Video]

    The Big Bang is pretty complicated stuff, especially if you're trying to explain it in less than four minutes. It happened billions of years ago, so there's no direct record of it. It created everything as far as we know, so we don't have any frame of reference for what came before it. And it rewrote the laws of physics as it happened, so even our best understanding of the phenomenon is necessarily inadequate. It's pretty daunting stuff, all things considered. That's why we're so glad that CERN physicist Tom Whyntie is on hand to offer the following excellent explanation of what we know and how we know it in the latest video offering from TED's education arm, TED-Ed.
