Physicists are now foretelling the death of cosmology, or the study of our universe, as we know it. Thankfully, cosmologists won’t be jobless for a couple trillion years. The universe is rapidly expanding–perhaps not rapidly enough to rip to shreds, but enough that distant galaxies will eventually be moving away faster than the speed of light. This much has been known for decades. Once all these galaxies blink out of existence, scientists ask in an upcoming issue of The Journal of Relativity and Gravitation, how will future intelligent beings study space if the human race’s knowledge is long gone? Will they be able to figure out if the Big Bang happened? Or rediscover relativity?
