A blazing supermassive black hole can influence far more than its own galaxy. Scientists found that quasars emit radiation strong enough to shut down star formation in nearby galaxies millions of ...

Here’s what you’ll learn when you read this story: A wormhole in nature (for select values of “nature,” of course) might be a similarly higher-dimensional shape that does not act the same when ...

In 1916, only a year after Albert Einstein had published his general theory of relativity, Karl Schwarzschild used mathematical calculations to show this: If sufficient mass could be placed into an ...

Astronomers have an answer for a long-running mystery in astrophysics: why is the growth of supermassive black holes so much ...

If physicists had a holy grail it would go by the name of Quantum Gravity. For 60 years researchers have been searching for a way to unite the very large and the very small into a single coherent ...

Some things in cosmology may simply be unknowable. Why is there something rather than nothing? What lies outside the universe? What is inside a black hole? That last one has been niggling at ...

For decades, wormholes have been hypothesized as mysterious tunnels that might let us cross galaxies or even time itself—but what if this picture is completely wrong? New study suggests that one of ...

Last year, astronomers were fascinated by a runaway asteroid passing through our Solar System from somewhere far beyond. It was moving at around 68 kilometres per second, just over double Earth’s ...

Physicists may soon witness a cosmic fireworks show: the explosive death of a primordial black hole. Once thought to be unimaginably rare, new research suggests there’s up to a 90% chance of catching ...
