Few ideas in modern science have reshaped our understanding of reality more profoundly than space-time—the interwoven fabric ...

“Using newer mathematical tools, my colleague and I have demonstrated a new theory that may accurately describe the universe. Instead of basing the theory on the warping of space and time, we ...

Observing time distortions could show whether Einstein's theory of general relativity accounts for the mysteries of dark matter and dark energy.

In 1918, Albert Einstein’s theory of general relativity predicted that the rotation of a massive object would warp space and time in its vicinity — essentially distorting the space-time ...

Step into the fascinating science behind Interstellar as we explore the extreme effects of time dilation near a black hole.

Space-time is more than a way of looking at the universe, it's a way of defining your place in it. In the conclusion to his essay on relativity, Paul Sutter tackles the impacts of relativity on ...

Relativity Space launched the world's 3D printed rocket on March 22, 2023. Though the rocket failed to reach orbit, it did pass some important milestones on its maiden voyage. "It was, at least ...

In the gloomy days of January, time seems to drag. According to the Einstein theory of relativity, it actually does—in a minute amount that means little to anyone except a scientist. During its ...

Relativity Space had been targeting Wednesday afternoon for the inaugural launch of Terran 1, the largest 3D-printed structure ever built.

Relativity Space is amping up its investment at NASA’s Stennis Space Center, with the company announcing today that it would lease a historic first-stage test stand to advance the development of ...
