The concept of spacetime, first described in Einstein's theory of general relativity, has since been widely studied by many ...

A new citizen science project invites the public to scan never-before-seen images from the Euclid Space Telescope in search ...

For decades, cosmologists have had an awkward number sitting at the center of their equations. The universe is expanding, and ...

The Sagittarius A* supermassive black hole at the core of the Milky Galaxy may be "warping the spacetime surrounding it into ...

An illustration of heavily curved spacetime, outside the event horizon of a black hole. As you get closer and closer to the mass's location, space becomes more severely curved, eventually leading to a ...

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: ...

Photons emitted by extragalactic sources provide an opportunity to test quantum gravity effects that modify the speed of light in vacuum. Studying the arrival times of these cosmic messengers further ...

That exotic structure in spacetime gave a team of researchers the tools they needed to identify a new class of object, something that they call a topological soliton. In their analysis they found that ...

Citizen scientists will look for warped spacetime using data from the European Space Agency's Euclid telescope.

Remember that time in the Lord of the Rings lore when the dwarves of Moria dug too greedily and too deep, unearthing the Balrog, an ancient horror not meant to roam free in the modern age? Cosmic ...

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 ...
