In the past, it was assumed that the universe would expand to a maximum in the future and then retreat again with the same gravity. However, the latest research, studies, and theories say that not only does it not stop expanding, but it actually expands faster and faster, so that the final goal seems to be total entropy.
What will happen when this maximum entropy is reached? Many thousands of years will pass. The future of the cosmos will probably be very different from what we know today. If we look at our closest zone of influence, the Sun will die in about 5000 years, after becoming a red giant, going supernova, and becoming a black hole or neutron star. At that time, the Earth will have long ceased to exist, having previously become a barren, burned-out planet.
Later, our galaxy, the Milky Way, will collide with the neighboring Andromeda Galaxy, which is also in the galactic neighborhood known as the Local Group. Many millions of years remain, but the effects will be brutal and are inevitable.
Future of the Universe
Although before that, if people on Earth are still here in a few thousand years, they will be able to see the star Betelgeuse explode. This red giant in the constellation Orion is very massive and is about to go supernova.
If we humans are still on Earth in 250 million years, we will have to say goodbye to the Moon. The moon moves a little further away from our planet every year until it can no longer exert enough gravitational pull on it to stay by our side.
More details about the possible the universe’s future
There are many other possibilities that scientists are working on. For example, it could be that the outer planets of the solar system change their orbits into irregular paths so that Jupiter could approach the Sun and destroy everything in its path.
There is also the possibility of the Earth’s core cooling, a phenomenon that is already a reality. There are many years ahead, but that seems to be the future of this rocky planet, as well as many others.
And, as a final hypothesis, before the universe reaches full entropy and the stars and galaxies are far apart, it could be that the expansion caused by dark energy becomes so strong and powerful that it destroys the entire universe because it is unable to withstand so much force. Will this be the moment when a big bang occurs and a new universe is created?
