The concept of time travel, filled with magic, has long danced on the boundary between science and science fiction. From ...

Thanks to Einstein's theory of relativity, numerous tests have concluded tangible effects on how we on Earth record and measure the passing of time.

Last week, we touched upon E=mc2, and how Einstein’s theory of relativity turned the world of physics upside-down. Now, we’re using that theory to show why the very concept of time may not be ...

Scientists using quasars as cosmic clocks have observed that when the universe was just a billion years old, time ran five times slower, helping to confirm Einstein's general theory of relativity ...

The No Man’s Sky team got around the time dilation problem by making faster-than-light travel the norm, throwing physics out the window.

I am so intimidated right now...I think I understand less about relativity now than before I asked the question. :) I think - if I understand things as written - that time can be observed to slow ...
