Researchers have unveiled a new model for the universe’s birth that replaces cosmic inflation with gravitational waves as the ...

Einstein's theory of general relativity views time similarly to width, height, and length. As such, both time and space can be curved by gravity. This effectively means that time is slower the closer ...

Scientists really don't understand time... but they do have some theories about what it might (and might not) be.

Two blind spots torture physicists: the birth of the universe and the center of a black hole. The former may feel like a moment in time and the latter a point in space, but in both cases the normally ...

A new collage from the James Webb Space Telescope reveals eight dazzling examples of gravitational lensing.

A mathematical test for the nature of space-time – the fabric of physical reality – may be the first step towards novel computer-like devices that process information using gravity. Eleftherios-Ermis ...

If you wave your hand in front of your face, you won’t notice anything particularly interesting. Perhaps a gentle waft of air against your cheek – that’s about it. No epiphany. No major sign that ...

The significant new round of investment ensures that Stoke will have the resources needed to slog through this period of ...
