A century after Albert Einstein unveiled a new concept to explain gravity, his so-called general relativity theory remains fertile ground for scientific observations and experiments.
Exactly 100 years ago on Nov. 25, 2015, physicist Albert Einstein, then 36, presented a fourth and final lecture to the Prussian Academy of Sciences about his new general theory of relativity.
To celebrate 100 years since Einstein formulated his theory of general relativity, we celebrate the beautiful observations created by a spacetime phenomenon known as gravitational lensing.
If this physics professor succeeds, we could use streams of neutron spins to transmit binary code back to the past. Continue reading →
Scientists are taking initial steps in a long-term effort to learn as much as they can about gravitational waves -- mysterious undulations in the fabric of space-time that have so far evaded clear detection.
Science fiction literature is full of stories in which tunnels in space-time — known as wormholes — are used for time travel. How much fact lies within the fiction? The answer is, more than you might think.
Our universe is actually really simple, it's just our cosmological theories that are getting needlessly complex, argues one of the world's leading theoretical physicists.
After undergoing a 5-year upgrade, the world's most powerful gravitational wave detector is back online and hunting for the tiniest of tiny fluctuations in spacetime.
