I have a question regarding time dilation that I thought of last night listening to an audiobook, Project Hail Mary. I am an amateur astrophotographer, and marvel at the distance to deep-space objects ...

Modern physics suggests time may be an illusion. Einstein's theory of relativity, for example, suggests the universe is a static, four-dimensional block that contains all of space and time ...

In 1959, physicists James Terrell and Roger Penrose (Nobel laureate in 2020) independently concluded that fast-moving objects should appear rotated. However, this effect has never been demonstrated.

Tracking time is one of those things that seems easy, until you really start to get into the details of what time actually is. We define a second as 9,192,631,770 oscillations of a cesium atom.

Despite more than a century of efforts to show otherwise, it seems Albert Einstein can still do no wrong. Or at least that’s the case for his special theory of relativity, which predicts that time ...

When an object moves extremely fast – close to the speed of light – certain basic assumptions that we take for granted no longer apply. This is the central consequence of Albert Einstein's special ...
