searching for wormholes with general relativity

If wormholes big enough for spaceships to traverse exist, we should be able to detect them just by looking at the sky.

the birth of a supermassive monster, revisited

While we still don't know how supermassive black holes get as heavy and large as they are, but we have a few ideas...

how hot could it get inside a black hole?

Black holes radiate virtually no energy, much less anything we'd consider heat. But that doesn't mean their innards aren't superheated to cosmic extremes...

mining physics for “groundbreaking” papers

A new paper concludes that black holes are periodically giving birth to new universes. How it arrives at that conclusion raises a lot of questions.

where to find the energy for a warp drive

While we'd need to generate an immense amount of energy to power a warp drive, there are events in this universe with that kind of energy output...

do quasars break the laws of physics?

Something is wrong in the data we get when we measure distances to far away quasars to see how fast the universe is expanding.

getting information from a black hole’s maw

What happens to particles swallowed by a black hole? The answer could either confirm our understanding of the universe or alter everything we know about it.

in the beginning, there was the black hole

At the dawn of the universe, enormous black holes were among the first things to be born, and at the end of it, they will be among the last to die.

say, how far away is that black hole?

A star-munching monster of general relativity is a lot closer to Earth than we thought according to new observations...

spaceships, now with black hole reactors?

Can we turn black holes into a way to explore space at relativistic speeds? A pair of physicists thinks it may be plausible if we have enough powerful lasers...
