Warp drives have long lived in the realm of science fiction, but the underlying physics that inspired them is very real and ...

In a groundbreaking exploration of physics, researchers have revealed a way to extend Albert Einstein's special theory of relativity to accommodate superluminal observers—those moving faster than ...

Here’s what you’ll learn in this story: Time might actually have 3 dimensions. But it also means that the space would actually be one-dimensional, instead of the three dimensions we’re familiar with.

Oftentimes, we think of space as an endless, mostly empty vacuum, a silent backdrop where planets, stars, and galaxies play out their dance. We also think of time as something separate, a steady ...

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 ...

TU Wien researchers have uncovered a quantum twist to the paths particles take through spacetime — one that could finally ...

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 ...
