Casimir cavities are mysterious spaces between microscopic metal plates in a vacuum. Areas of diminished energy between the plates cause them to push toward each other, as if trying to fill the ...

Intense radiation emitted by active supermassive black holes—thought to reside at the center of most, if not all, galaxies—can slow star growth not just in their host galaxy, but also in galaxies ...

Physicists artificially slowed down time to reveal the bizarre Terrell-Penrose effect, a consequence of special relativity. This image from the experiment shows a sphere seemingly moving at 99.9 ...

This is an example of time dilation, a consequence of the idea that time and space are not absolute - meaning all observers do not always measure these quantities as the same. In everyday life we use ...

Since the 1990s, astronomers have found a handful of other dwarf planets in the belt, such as Eris and Sedna, along with ...

Physicist Kip Thorne discusses the real science behind Interstellar, explaining how the film portrayed black holes, time dilation, and space travel with scientific precision.
