A black hole may be millions of light-years away, but some of its strangest physics has now been recreated in a Manhattan ...

More than half a century ago, Sir Roger Penrose envisioned a scenario in which energy could be extracted from a black hole ...

More than 50 years ago, Nobel Prize-winning physicist Sir Roger Penrose proposed an extraordinary idea. He suggested that it ...

A new study shows that time-variations in tailored materials can reproduce the physics of ultrafast rotating bodies, enabling ...

Astronomers are closer to solving the mystery of how supermassive black holes feed themselves thanks to new images from the ...

Under that reasoning, certain exotic structures of spacetime called closed timelike curves may be real—and they may allow a message to travel from the future to the past. A new study has calculated ...

Black holes are some of the most mysterious objects in the universe, but they aren’t always silent. When two black holes are close enough to each other, they spiral towards one another, eventually ...

Observations from NASA’s James Webb Space Telescope showed that more galaxies rotate in one direction than the other. According to one researcher, this could mean that the universe is actually inside ...
