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 before human spaceflight has finally proved general relativity right, according to NASA.

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 Earthbound twin has aged much more than he has. Why is that? Watch this video to find out the simple explanation with animated cartoons.
