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 theory ...

‘I love the idea that this basic principle that Einstein told us about a long time ago is something you can see,’ CU Boulder astrophysicist says Scientists who study the cosmos have a favorite ...

How would our world be viewed by observers moving faster than light in a vacuum? Such a picture would be clearly different from what we encounter every day. "We should expect to see not only phenomena ...
