Astronomers Discover First Direct Proof of the Big Bang Expansion

Somebody's going to win a Nobel Prize. At least that's what the physics community is saying after the announcement on Monday that a Harvard team has found the first direct evidence of cosmic inflation right after the Big Bang. It's more proof that the Big Bang really was the beginning of it all. » 3/17/14 12:20pm 3/17/14 12:20pm

How Quantum Theory Screws With Our Perception of Reality

Our modern understanding of reality is based on some fundamental concepts: that the world around us is tangible, that the theory of relativity holds, that cause and effect works as we'd expect, and that humans have free will. But take quantum theory at face value, and it turns out the four can't co-exist together. » 8/08/13 4:43am 8/08/13 4:43am

Super-Fast Space Travel Would Kill You in Minutes

Everyone thinks it would be cool to travel at the speed of light, which is why scientists devote their lives to working out if it would be possible and NASA is trying to develop its own warp drive. But easy, tiger: turns out super-fast space travel would be fatal. » 11/05/12 9:00am 11/05/12 9:00am

Faster-Than-Light Travel May Be Possible

According to Einstein's special theory of relativity, light traveling in a vacuum is the universal speed limit. But scientists love to try and break rules—and now a tweaked version of Einstein's equations suggests that faster-than-light travel might just be possible. » 10/12/12 8:16am 10/12/12 8:16am

NASA Gravity Experiment Proves Einstein Was Right

Like a beach chair sagging under a sunbather's weight, the fabric of spacetime does indeed warp around the mass of the Earth - just as Albert Einstein predicted. And like a swimmer moving through the water, the rotation of the Earth affects the movement of spacetime itself. A gravity probe whose origins date to the era … » 5/05/11 10:40pm 5/05/11 10:40pm

This Animated Video Simplifies Einstein's Complicated Twin Paradox

Einstein's Twin Paradox is super confusing for me, every time I think I fully understand it, I find more questions. The Twin Paradox is a thought experiment in special relativity when one twin travels to outer space while the other twin stays on Earth. When the space bound twin lands back on Earth, he'll find that his … » 2/20/11 4:00pm 2/20/11 4:00pm
