Our universe plays by certain rules, which originate from different branches of physics. But sometimes the rules seem ...

Time travel has shifted from pure fantasy to a serious, if highly constrained, topic in modern physics. The equations that ...

The answer comes from a counterintuitive result of special relativity, a field of physics which is notoriously difficult to ...

Time feels like the most familiar thing in the world, yet it hides one of physics’ hardest questions: why do we only remember the past and never the future, and why do broken eggs not leap back into ...

In Newtonian physics, space and time had their independent identities, and nobody ever got them mixed up. It was with the theory of relativity, put together in the early 20th century, that talking ...

Thanks to Albert Einstein, the US Government wants to establish an official time zone for the Moon. It has less to do with jet lag and more to do with how gravity affects time and can throw a lot of ...

Observing time distortions could show whether Einstein's theory of general relativity accounts for the mysteries of dark matter and dark energy. When you purchase through links on our site, we may ...

OUR most accurate clocks are probing a key tenet of Einstein’s theory of relativity: the idea that time isn’t absolute. Any violation of this principle could point us to a long-sought theory that ...
