How Will the Universe End? Scientists Say They May Have an Answer


sciencehabit shares a report from Science Magazine: In the unimaginably far future, cold stellar remnants known as black dwarfs will begin to explode in a spectacular series of supernovae, providing the final fireworks of all time. That’s the conclusion of a new study, which posits that the universe will experience one last hurrah before everything goes dark forever. The dramatic detonations will begin to occur about 10^1100 years from now, a number the human brain can scarcely comprehend. The already unfathomable number 10^100 is known as a googol, so 10^1100 would be a googol googol googol googol googol googol googol googol googol googol googol years. The explosions would continue until 10^32000 years from now, which would require most of a magazine page to represent in a similar fashion.

A time traveler hoping to witness this last cosmic display would be disappointed. By the start of this era, the mysterious substance acting in opposition to gravity called dark energy will have driven everything in the universe apart so much that each individual black dwarf would be surrounded by vast darkness: The supernovae would even be unobservable to each another. The study has been published in the journal Monthly Notices of the Royal Astronomical Society.
