A Journey to the End of the UniverseCould humans ever travel to other galaxies within their lifetime? The immense scale of the Universe seems to prohibit such voyages, after all the nearest galaxy is so far away that it takes light itself - the fastest thing in the Universe - 2.5 million years to complete the trip. Remarkably, there is a trick that might allow humans to accomplish this feat - join us today as we step onboard the constantly accelerating spaceship!
