What does it mean to be to space-time? The seemingly simple question gets to the essence of twentieth-century physics and has driven a hundred-year debate between philosophy and science. In Einstein’s ...

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

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

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 ...

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 ...

In the 10 years since the first detection of gravitational waves, we have detected hundreds of these waves produced by the ...

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 ...

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 ...

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 ...

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

"The singularity is the most mysterious and problematic part of a black hole. It's where our concepts of space and time literally no longer make sense." A team of scientists has developed a recipe for ...

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 ...
