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 ...

A good scientific theory is one that allows us to calculate the results of many observations from few assumptions.” — Physicist Sabine Hossenfelder Hossenfelder’s concise statement explains why the ...

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 ...
