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.
For the first time, the mass of a binary pulsar pair has been precisely measured, but it was a race against time before the extreme gravitational warping of spacetime caused one of the dense objects to blip out of view.
How does time stop everything from happening at once? What mechanism drives time forward, but not backward? Continue reading →
Dimensions are complicated. Wrapping your head around how many there are can give you a headache. Trace explains everything you should know about them.
Through the analysis of light from distant galactic clusters, astronomers have detected a mysterious signal that they're having a hard time explaining. Continue reading →
A physicist has revisited wormholes, potentially finding a way to send a signal through time. Continue reading →
If we could harness the energy generated by an evaporating black hole, we might be able to bridge the vast space between the stars.
Physicists have tried searching for time travelers on the Internet. But they didn't find any.
