One of Einstein's predictions is that we should see time moving at different rates at different ages of the Universe. Researchers have confirmed this prediction out to half the age of the Universe using Type 1a supernovae as standard candles. Astronomers have gone much further back in time, observing quasars that sent out their light 12 billion years ago. Over this vast distance, time has slowed to a crawl, with every second experienced by those quasars taking five seconds from our perspective. ...
