Hold onto your hats, space watchers, because this news is HUGE. Scientists have detected gravitational waves for the first time -- ripples in spacetime that back up Einstein's work and let us eavesdrop on cosmological chaos.
What are they? Why are they important? Why should we care?
More gravitational wave discovery rumors are flying, but this time they've taken a specific -- and, possibly, really exciting -- new twist.
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.
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.
Has Stephen Hawking found the 'emergency exit' for information falling into a black hole?
A new spacecraft will test ideas to find gravitational waves in the universe.
A newfound giant black hole nearly as massive as 7 billion suns is dozens of times larger than astronomers expected given its host galaxy's size, researchers say.
