The future of the species and the universe could be one of the most complex endings. Among the theories, the black holes will evaporate, there will be increasingly expanded radiation and if cosmic expansion continues, atoms and planets will disappear. The Universe emerged when there was a release of energy from the vacuum, which was transformed into matter and the cosmos began to expand, sooner or later it would have to end, but the question is how it will do it.
Throughout this process of creation, galaxies, the Solar System, planets, and phenomena such as photosynthesis and the formation of food emerged, and then the appearance of the first species of living beings. However, science knew one thing: the future would have an endpoint.
A Look to the Future This Will Happen
Initially, it is known that the Sun will live another four thousand 500 million years, and when this stage passes, it will begin to consume nuclear fuels other than the ones it has, which are hydrogen and helium. Meanwhile, the Earth will disintegrate, it will melt because it will be on the edge of a gigantic star to which the Sun will approach and the elements expelled by the star will probably mix with another cloud of interstellar matter, But what else will happen and how long will it take, will we have counted the time?

1. Precession of the poles
1,100 years in the future. Due to the precession of the poles, Gamma Cephei replaces Polaris as the “Polar Star” in the northern celestial hemisphere.
2. Crashes
In about 10,000 years, the supergiant Antares will have exploded as a supernova and will be seen from Earth during the day.
3. Climates will change more
In 15,000 years, the tilt of the Earth’s poles will move the North African monsoon enough to change the Saharan climate to a tropical one, like what it had 5,000 to 10,000 years ago.
4. The glacial period will return
In about 50,000 years, the current interglacial period will end, sending Earth back into a glacial period of the current ice age. Yes, we live in an interglacial period, regardless of the effects of anthropogenic global warming.
5. Betelgeuse will explode
One million years is the maximum estimated time until the supergiant star Betelgeuse explodes as a supernova. For months, the supernova will be visible on Earth in daylight. Some studies suggest this may occur even in 100,000 years or less.
6. Stars in constant proximity Sun
In one million 280 thousand years, the star Gliese 710 will pass 0.221 light-years (14,000 AU) from the Sun, becoming the closest star. This will gravitationally perturb members of the Oort cloud, and increase the probability of cometary impact in the inner Solar System.
7. Increase in time on Earth
180,000,000 years. Due to the gradual slowing of the Earth’s rotation, a day on Earth will be one hour longer than it is today. The days will have 25 hours.
8. Will the dinosaurs return?
By 400-500 million, the supercontinent will have broken apart. This is likely to result in higher global temperatures, similar to those of the Cretaceous period, with a global tropical environment.
Goodbye to the Moon
Within 600 million years, tidal acceleration moves the Moon far enough from Earth that total solar eclipses will no longer be possible. There will only be annular and partial eclipses.
9. Nothing new
In 850 million years. The increase in the Sun’s luminosity increases to the point that CO2 levels fall and photosynthesis will no longer be possible. Without plant life to recycle O2 in the atmosphere, free oxygen and the ozone layer will disappear from the atmosphere.
10. Goodbye to plant life
In about 1.2 billion years, almost all plant life will be extinct. If there were plants that do not carry out photosynthesis, the high temperatures would make life unsustainable.
11. That’s why they want to take us to Mars
In 1.5 billion years. The Sun’s habitable zone is moving toward the outer solar system. Mars now has temperatures like Ice Age Earth.
12. We become the red giant
In 2.5 billion years. All the seas on Earth evaporate. The average temperature of the Earth, even at the poles, is 150ºC. This is due to the increase in the luminosity and temperature of our star, prior to its “red giant” phase.
13. Andromeda and the Milky Way come together
Between 5 billion and 7 billion years in the future, the Andromeda Galaxy will have completely merged with the Milky Way, forming a single galaxy.
14. The Earth is absorbed
7.6 billion years. Earth and Mars will possibly be absorbed by the Sun as a red giant. Titan, with temperatures similar to those of Earth today, will become an ocean world shortly after in 8 billion years. The Sun has become a white dwarf.
15. A single galaxy
In 100,000 million years. The entire Local Group (Milky Way/Andromeda; Triangle Galaxy and all its satellite galaxies) has merged into a single galaxy. This means that in 325,000 million years. All the stars in the universe are isolated, so someone on a planet of any star will be unable to see stars or other objects in the sky except their planet’s satellites.
As a consequence, new stars stop forming because all the interstellar gas has been exhausted. Thus, the planets that remain will be wandering worlds, tied to no star.
16. Only supermassive holes and the Dark Ages will exist
In a zillion years. Time in which all the planets have fallen into stars and these have fallen into supermassive black holes. Only these objects exist. All supermassive and stellar black holes will have been dissipated by Hawking Radiation. We enter the Cosmic Dark Age, in which only subatomic particles remain in the universe, until their final disintegration
