The theorized unseen structure of spacetime could also explain of the outstanding questions about the accelerating expansion ...

Astronomers have observed a star wobbling in its orbit around a ravenous supermassive black hole that is ripping it apart and feasting on its stellar material. The observation is ...

For more than 100 years, physicists have known — at least on paper — that spinning black holes should stir the universe around them. Now, thanks to the violent death of a distant star, astronomers ...

A star’s fatal brush with a supermassive black hole can light up a quiet galaxy. When gravity shreds the star, its gas ...

Astronomers have detected spacetime itself being dragged and twisted by a spinning black hole for the first time. The discovery, seen during a star’s violent destruction, confirms a prediction made ...

A doomed star spiraling into a supermassive black hole has given physicists one of their clearest looks yet at how gravity ...

Engineers have found a way to shepherd microrobots with no wires, no radios, and no onboard computers. Instead, they steer them with light patterns designed using the same math physicists use to ...

Spacetime itself would also need to be “quantized,” or broken down into constituent parts. This is what the notorious string theory attempts to do, as does loop quantum gravity, currently considered a ...

What if spacetime were a kind of fluid? This is the question tackled by theoretical physicists working on quantum gravity by creating models attempting to reconcile gravity and quantum mechanics. Some ...

The biggest lesson from Einstein's general theory of relativity is that space itself isn't a flat, unchanging, absolute entity. Rather it's woven together, along with time, into a single fabric: ...

A team of cosmologists in Finland and Poland have proposed that the accelerated expansion of the universe, usually explained by dark energy, may actually be the result of "Tardis regions" of spacetime ...

Forbes contributors publish independent expert analyses and insights. The Universe is out there, waiting for you to discover it. When it comes to understanding the Universe, there are a few things ...
