One Hundred Quintillion Years

Not taking into account the first 10,000,000,000 years, the following events make up a very brief overview of the next 100,000,000,000,000,000,000 years:

• [+14,400,000,000] Sun = Black Dwarf: Its temperature and luminosity will plummet, making it invisible to human eyes (not that they exist any more).
• [+20,000,000,000] The Big Rip: One potential end of the universe. All matter will be torn apart by the expansion of the universe. All distances will become infinite – not good.
• [+100,000,000,000] Local Group Merge: All local galaxies will start to merge. This process will take nearly one trillion years.
• [+150,000,000,000] Cosmic Microwave Background: The afterglow of radiation from the Big Bang will cool from -27OC to near absolute zero, making it undetectable to current technology.
• [+1,000,000,000,000] Earliest End Of Star Formation: Galaxies will have lost the gas clouds needed for star-formation. – Earliest estimate.
• [+100,000,000,000,000] Latest End Of Star Formation: Lowest estimate for the end of stellar birth. The beginning of the ‘Degenerate Era’ of universe-wide star death.
• [+110,000,000,000,000] Star’s Fuel Exhausted: All stars will have died. The only objects left are remnants: white dwarfs, neutron stars, black holes.
• [+100,000,000,000,000,000,000] Earth Dies: If not consumed by a swollen Sun at 5.4 billion years, the Earth’s orbit will have finally decayed and it will plunge into the Sun.
