We all have heard that one day, the earth is going to end and this comes from either our religious background or from scientific theories. Whichever one you were opportune to listen to, they all pass one message which is that the earth is not going to be around for too long but let's look science at this point.
The earth is going to be destroyed as the sun would explode, water dry completely and a whole myriad of events that would lead to the destruction of earth. Someone asked a person that if the earth isn't going to end soon, why are scientists making it look like it would end tomorrow. Actually, the world isn't going to be burned by the sun anytime soon, rather we still have between 4 billion to 6 billion years before we experience the earth's apocalypse. Not just earth, the entire universe will surely come.
Just the same way there was the Big bang, we might have the big hit which would be courtesy of another another galaxy like Andromeda. Andromeda is the milky way closest galactic neighbor with 2.537 million light years as at the time of me writing this post but then it is closing up with our galaxy at a speed of 110 kilometers per second and this meas that in abut 4 billion years, two galaxies with crash and merge to become one just like other galaxies have been colliding on regular basis with one another but even when galaxies are spread apart as a result of the universe expanding but gravity although weak still brings them together. Although the gravitational force can be weak as a result of distance, it is never zero.
During the crash of the galaxies, new galactic bodies are born including stars and planets. As the universe collapse, the energy that are emitted from the stars and planets are drawn into any black hole the temperature of the space increases extremely leading to the nuclear explosions of stars and planets. Scientists have been able to see that as the universes expands, it makes more empty space which would mean dark energy and this will be separating the galaxies afar.
Vacuum decay is one way that we might lose our universe and this would happen very fast. With the Higgs field that permeates all space with its energy on the scale of particles and atoms including electrons and quarks, as well as we living being are able to hold ourselves together because of the value of Higgs field and it is pretty stable at a low energy but when there is a high energy explosion, it could to higgs field value to lower creating a bubble that would swallow the universe after which the space inside collapse into a black hole. While we might not be able to trigger vacuum decay by ourselves, the universe can but the universe might never do so.
