On the Closed Universe

“The universe is like a safe to which there is a combination, but the combination is locked in the safe.”

– Peter de Vries

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.

One Hundred Million Years

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

  • [+50,000,000] Mediterranean Gone: Africa will collide with Eurasia, sealing off the Mediterranean Basin and creating a mountain range similar to the Himalayas.
  • [+50,000,000] Antarctica Ice Melt: The Antarctic ice will travel north and melt, causing the sea levels to rise with 75 meters.
  • [+50,000,000] Merging Islands: The islands of Indonesia will merge with Australia.
  • [+50,000,000] Galactic Empire: At this time, the entire galaxy could probably be colonised even at sub-light speeds.
  • [+60,000,000] Earth’s Orbit Unpredictable: The effects of gravity multiply over long periods, this will make orbits chaotic and impossible to predict.

One Million Years

Not taking into account the first 100,000 years, the following events make up a very brief overview of the next 1,000,000 years:

  • [+296,000] Voyager 2 vs Sirius: The space probe will pass within 4.7 light years of the brightest star in the sky.
  • [+500,000] Asteroid Strike: The Earth will probably have been hit by an asteroid with a +1km diameter by now.
  • [+500,000] Safe Plutonium: The spent nuclear fuel in today’s reactors will be safe.
  • [+500,000] New Ice Age: A new global freeze will probably have made life on Earth very difficult for a large number of organisms by now.
  • [+1,000,000] Betelgeuse Explosion: The red supergiant will have exploded by now; the explosion will probably be visible in daylight.
  • [+1,000,000] Monuments: Massive stone structure like the Giza pyramid or stone sculptures like Mount Rushmore may still exist – everything else we see around us today will no longer be around.
  • [+1,000,000] Glass Decomposed: All glass created to date will have degraded.

Ten Million Years

Not taking into account the first 1,000,000 years, the following events make up a very brief overview of the next 10,000,000 years:

  • [+1,450,000] Galactic Near Miss: The star Gliese 710 will pass about 1.1 light years from the Sun. Close enough to perturb the Oort cloud, triggering penetration of comets into the inner solar system.
  • [+4,000,000] Pioneer 11: The probe will pass the Lambda Aquilea system, 125 light years from Earth.
  • [+5,000,000] Men Extinct: The Y chromosome will have weakened to the point of crumbling – making men impossible.
  • [+7,200,000] Mount Rushmore: Mount Rushmore will have eroded away.
  • [+8,400,000] LAGEOS Re-entry: The satellite’s orbits are programmed to decay and re-enter Earth’s atmosphere carrying messages and maps to future descendents of humanity.
  • [+10,000,000] New Ocean: The Red Sea will flood, dividing the continent of Africa.
  • [+10,000,000] Earth Irradiated: Star T Pyxidi, 3,260 light years away goes supernova. Close enough to bathe the planet with gamma radiation, triggering mass extinctions.

One Hundred Thousand Years

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

  • [+13,000] Earth’s Axial Tilt Reversed: The Earth will tilt away from the Sun in June – the Northern hemisphere will experience more extreme weather due to the higher percentage of land.
  • [+18,860] Calendars Concur: the Islamic and Georgian calendars will share the same year: 20,860.
  • [+20,000] Chernobyl: the damaging radioactivity at Chernobyl, Ukraine will be gone.
  • [+25,000] Arecibo Message: Sent on 16 November 1974, radio data from the Earth will be received by globular cluster Messier 13 at the far side of the galaxy.
  • [+50,000] Greenland Ice Melted: The ice at Greenland will be completely melted with moderate global warming (+2C).
  • [+50,000] KEO Time Capsule: Launched in 2014, the time capsule will re-enter the Earth’s atmosphere. It has enough capacity to carry a four-page message from everyone on Earth.
  • [+50,000] Niagra Falls Disappears: The remaining 32 kilometres to Lake Erie will erode away and the waterfall will cease to exist.
  • [+100,000] Nearby Supernova: the red giant VY Canis Majoris will likely explode into a Hypernova.
  • [+100,000] Laptop Disappearing: The titanium in laptops will start to corrode.
  • [+100,000] Constellations: The stars in the heavens will look completely different due to Earth’s movement through the galaxy.
  • [+100,000] Global disaster: Either a supervolcano or a large climate-altering asteroid will probably have affected the Earth by then.
