Why This Astronaut Thinks NASA Can Save Humanity From Extinction

Astronaut Daniel T. Barry thinks NASA's mission to Mars is humanity's most important endeavor yet, for reasons including the birth of Captain Kirk. We talked to him about what it's like to explore the Final Frontier. » 3/23/15 4:04pm 3/23/15 4:04pm

Watch a feather and a bowling ball fall at the exact same speed

To this day, I've never felt dumber than when elementary school me thought that 100 pounds of bowling balls would fall faster than 100 pounds of feathers. This video doesn't show that riddle in action but something even cooler: how things fall at the same rate inside the world's largest vacuum chamber. » 11/03/14 9:21pm 11/03/14 9:21pm

Antarctica Is Losing So Much Ice It's Throwing Off Earth's Gravity

Rising sea levels inundating coastal cities are the least of our global warming problems. According to a new report by the European Space Agency, the loss of snowpack along the antarctic ice shelf is throwing off Earth's gravitational field. Yeah, pretty sure that's bad. » 9/30/14 4:35pm 9/30/14 4:35pm

Low Gravity Makes Astronauts Fall Over

In the good old days of moonwalks, NASA astronauts fell over quite a lot. But they weren't being clumsy or struggling with their suits: despite what you might think, low gravity actually makes it harder for astronauts to say upright. » 9/11/14 8:00am 9/11/14 8:00am

America's first roller coaster began as a railway for transporting coal

If you're wondering how people first decided plummeting downhill inside a rickety box on wheels seemed like a good time, look no further than the Mauch Chunk Switchback Railway in Pennsylvania. What began as a railway for shooting coal down the mountain turned into a destination for thousands of tourists in the late… » 9/04/14 6:15pm 9/04/14 6:15pm

New map shows where the Milky Way galaxy is inside its supercluster

For the first time, scientists have pinpointed where our galaxy stands amongst thousands of other galaxies in our home supercluster. The new map shows beautiful feathery strings linked together with the Milky Way galaxy placed on the edge of the newly named Laniakea supercluster, home to 100,000 other galaxies. » 9/03/14 6:36pm 9/03/14 6:36pm

Neil deGrasse Tyson Explains Everything Wrong With the Movie Gravity

Gravity is a positively stunning, occasionally horrifying cinematic masterpiece. Of course, that said, it's got its share of problems. And no one has been more irked by these discrepancies than everyones favorite astrophysicist, Neil deGrasse Tyson.

12 Excellent Movies That Use VFX To Tell A Story

It's summer movie season, which means lots of effects-heavy, big budget romps. And it's easy to feel numbed by all this digital overkill.

Just check out our list of 12 movies that use VFX purely as a storytelling tool. » 5/07/14 4:39pm 5/07/14 4:39pm

Genius Gravity scene featuring Superman ruins/fixes the whole movie

Haha, this is super silly but if you enjoyed the roller coaster ride that was Gravity and wished you were a superhero once before in your life, you should enjoy this fun mash-up video that creates a fake "deleted scene" that changes the entire movie. » 4/02/14 9:42pm 4/02/14 9:42pm

This cool pad and pen lets you sketch in 3D using augmented reality

Gravity is a pen and pad that allows to sketch in 3D space using augmented reality. The cool patent-pending system hardware and software system has gone through several working prototypes and now they are looking to start manufacturing. Check out the video—it's pretty cool. » 3/28/14 5:16pm 3/28/14 5:16pm

You Can't Steer a Bike in Zero Gravity, Even If The Road's Magnetic

Gravity is the sworn enemy of any cyclist. Succumb to its force while you're on two wheels, and you'll end up bloody and bruised. But like any superhero's nemesis, gravity justifies a bike's very existence, because without it, you'd never be able to steer. Strap on a helmet, this is gonna get weird. » 3/28/14 3:00pm 3/28/14 3:00pm

You Haven't Seen Gravity Until You've Seen It in a Weightlessness Tank

Forget IMAX 3D. If you really want to see Gravity as it was meant to be seen, then this personal screening room/bathtub/human storage pod a la The Matrix is the only way to go. » 3/12/14 6:20pm 3/12/14 6:20pm

This guy basically destroys all laws of physics and gravity

You know those genius, almost sentient quadcopters that can learn new skills like juggle balls, fly in tandem, work together, go through hoops, attach themselves to wall and basically do things that will eventually destroy mankind? This guy, Kai Hou, is like the human equivalent of those. He's an acrobatic master that… » 2/14/14 11:14pm 2/14/14 11:14pm

Watch all of Gravity animated to 60 hilarious seconds

Miss the space roller coaster ride that was Gravity? Then you missed out on Sandra Bullock's stressful spinning, George Clooney's charisma soaked storytelling and a beautiful movie that seemed to be done in one endless take. It was a fun ride. But not nearly as fun as this animation of Gravity boiled down to 60… » 2/10/14 8:06pm 2/10/14 8:06pm

Here are the three ways that the universe will be destroyed

Nothing lives forever, not even our universe. Eventually it'll go kaput and be destroyed... but how? Smart people have wrapped their heads around the universe's destruction and have come upwith three different theories. The Big Rip, Heat Death (or the Big Freeze) and the Big Crunch and Big Bounce. They all sound like… » 2/04/14 6:46pm 2/04/14 6:46pm

This space fly proves that humans aren't cut for interplanetary travel

If this fly looks weird to you it's because it's dead—covered in the fungus that killed it. It's a very special type of Drosophila—one born and raised in space—and it proves that interplanetary travel could be really bad for the human immune system. So bad that we may end up dead, killed by some stupid infection. » 1/29/14 2:18pm 1/29/14 2:18pm

How Gravity Would Be Different If the World Were a Cube

Perhaps the main difference if the earth were a cube would be that students would become much more frustrated trying to calculate the gravitational field. For a uniform cube with side length L and density rho, the gravitational force on mass m at position (x,y,z) is given by » 12/31/13 11:00am 12/31/13 11:00am

The Fukushima Earthquake Actually Changed Earth's Gravity

The 2011 Tohoku earthquake, which caused the tsunami behind the Fukushima Daiichi nuclear meltdown, disrupted more than man-made structures. The European Space Agency's GOCE satellite, measured a significant change in Earth's gravity after the earthquake before falling out of the sky on November 11th. » 12/03/13 10:45am 12/03/13 10:45am

This hilarious parody of Gravity set in IKEA is spot on

Space is beautiful. Space is terrifying. IKEA is mostly just terrifying, especially when you get lost. Director Daniel Hubbard hilariously spoofed Alfonso Cuaron's Gravity by setting it inside the expansive world of IKEA. At over 346,000 square feet and absolutely no sense of direction, it sure feels endless. The… » 11/13/13 9:01pm 11/13/13 9:01pm
