Knowing the distribution of dark energy tells astronomers that the Universe will continue to get bigger indefinitely.
Eventually it will become a cold, dead wasteland with a temperature approaching what scientists term "absolute zero".
Professor Priyamvada Natarajan of Yale University, a leading cosmologist and co-author of this study, said that the findings finally proved "exactly what the fate of the Universe will be".
