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 ...

Interstellar object 3I/ATLAS has seemingly confirmed Einstein's general relativity by exhibiting gravitational lensing as it neared the Sun. However, the observed light bending exceeded predictions by ...

In this video, we explore Albert Einstein's theory of general relativity, focusing on his insights into gravity and ...

Albert Einstein, everyone’s favorite wild-haired genius with a mischievous grin, is more than just a pop culture icon whose legend lives on today. He’s arguably the most influential scientist of the ...

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 ...

Whether space-time exists should neither be controversial nor even conceptually challenging, given the definitions of “space-time,” “events” and “instants.” The idea that space-time exists is no more ...

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 ...

Black holes are so strange that physicists have long wondered if they are quite what they seem. Now we are set to find out if they are instead gravastars, fuzzballs or something else entirely ...

The first Terran R is under construction, with several components completed in recent weeks. One such component is the thrust ...

Two recently observed black hole mergers, occurring just weeks apart in late 2024, have opened an extraordinary new window ...

The significant new round of investment ensures that Stoke will have the resources needed to slog through this period of development hell, which could be especially pronounced for a rocket featuring ...
