The future of the universe

In the past it was thought that the future of the universe was to expand to a maximum that, once reached, by the same force of gravity would retract again. However, the latest research, studies and theories claim that not only does it not stop expanding, but it does so faster and faster, so it seems that the final destination will be total entropy.

What will happen when this maximum entropy is reached? There are many thousands of years left, but the future of the cosmos is going to 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, causing a supernova and becoming a black hole or a neutron star. By then, Earth will have long since ceased to exist, previously becoming a barren, burned-out planet.

Later, our galaxy, the Milky Way, will collide with neighboring Andromeda, also from the galactic neighborhood known as the Local Group. There are many millions of years left, but the impact will be brutal and it is inevitable.

Although previously Earth humans, if it’s still here in a few thousand years, maybe they’ll see the star Betelgeuse explode. This red giant in the Orion constellation is very massive and is about to go supernova.

And perhaps before that, if in 250 million years we humans are still on Earth, a rare and difficult thing, we will have to say goodbye to the Moon, which each year separates a little more from our planet until this world cannot exert enough gravitational force to make it stay by our side.

There are many other possibilities that scientists are working with. For example, it could be the case that the outer planets of the Solar System transform their orbits into erratic ones, with which Jupiter could approach the Sun destroying everything in its path.

It is also a possibility that the Earth’s core cools, a phenomenon that is already a reality. There are many years left, but it seems that it is 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 tremendously far apart, it could be that the expansion by dark energy becomes so strong and powerful that it ends the universe altogether. completely for being unable to withstand so much force. Is that the moment in which a Big Bang will take place that will give rise to a new universe?
