Astronomers armed with exceptionally detailed James Webb Space Telescope (JWST) images have discovered dozens of ancient ...

There’s so much mass in this megacluster that its gravity warps the fabric of spacetime ... us for decades—and then it will be time for the Roman Space Telescope to pick up the mantle and ...

The grandfather paradox is just one of the thorny logical problems that arise with the concept of time travel. But one ...

For the first time, researchers have used data from the James Webb Space Telescope (JWST) to uncover an example of a previously hypothetical phenomenon known as an "Einstein zig-zag" — where ...

Special relativity tells us motion warps space and time. Einstein’s central coup with general relativity was to combine that with a principle noted over three centuries earlier by Galileo ...

Around sufficiently large masses with strong gravitational fields, space-time itself curves and warps – like the mat of a trampoline warps under a bowling ball. Any light that travels through this ...

Cosmic strings, as predicted by Einstein’s theory, could warp space-time to create loops enabling backward journeys in time. 'Dream portals': Is your subconscious traveling to parallel universes ...
