spacetime

You can't see or feel it, but everything around you -- including your own body -- is slowly shrinking and expanding. It's the weird, spacetime-warping effect of gravitational waves passing…

Two massive touching stars in a neighbouring galaxy are on course to become black holes that will eventually crash together, generating waves in the fabric of space-time, according to a new…

Most of the matter in the universe, amounting to a staggering 85% by mass, cannot be observed and consists of particles not accounted for by the Standard Model of Particle Physics (see…

When a gravitational wave passes through Earth, it causes space itself to stretch in one direction and compress in the other, so the two “arms” of the detector actually grow and shrink by…

In a laboratory experiment, researchers from Heidelberg University have succeeded in realising an effective spacetime that can be manipulated. In their research on ultracold quantum gases,…

The first detection of gravitational waves in 2016 provided decisive confirmation of Einstein’s general theory of relativity. But another astounding prediction remains unconfirmed: According…

There has been a lot of debate on whether space-time travel through wormholes is possible or not. Most studies have suggested these hypothetical shortcuts are not possible as any passage of…

The favorite space travel maneuvers in and out of a wormhole of science-fiction fables could be more real than we thought. Physicists initially did not know whether black holes existed in…
