A violent stellar disruption recorded in 2024 has given astronomers their most comprehensive evidence yet of a black hole twisting the very fabric of spacetime around itself. This effect is known as ...

We present visual calculations in special relativity using spacetime diagrams drawn on graph paper that has been rotated by 45 degrees. The rotated lines represent lightlike directions in Minkowski ...

There are two broad categories of watches which one could rightfully label as “space watches.” But if you want a watch that measures how you, the wearer, are actually moving through space and time, ...

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 ...

URBANA, Ill. — Three atomic clocks, each no bigger than a grain of sand, suspended at different heights around a city. But these aren’t ordinary timepieces; they’re quantum devices that exist in ...

How Species' lofty science-fiction ideas were consumed by its monster instincts. When you purchase through links on our site, we may earn an affiliate commission. Here’s how it works. Given its ...

The first time a physicist told me they wanted to get rid of space-time, on a cold January morning earlier this year, I stopped typing my interview notes and clutched my New Scientist mug of tea.

Abstract: The spacetime triangle diagram technique is applied for investigation of scalar and electromagnetic waves emanated by pulsed line sources of finite cross section. It is shown that the ...
