According to the recently conducted studies, it has been estimated that the universe will not end for an extremely long time. It is believed that the universe is still expanding because of the initial forces of the big bang theory. However, the actual answer to this question really relies on the availability of the physical matter that exists in the universe.
The opinion of the scientists and researchers vary on the subject of universe. While some believe the world might end soon, others feel that the big bang theory is continuing and if there is sufficient physical matter left in universe, it will continue to grow and expand for something over millions of years.
The scientists have conducted studies that tell that if there is sufficient matter available in the universe, the forces of gravity will attract each bit of the matter and eventually it will stop the outward expansion of space. When this stage arises, the physical matter will start to collide instead of expanding because of the gravitational pull and there will be a point in time when the universe will fall inwards upon itself. Some scientists have even names this phenomenon of universe collapse as the ‘big crunch’.
On the other hand, the contemporary cosmetologists believe that the universe will continue to last for a long time, something like googleplex years, which is considered a very large number comprising of thousands of zeroes.
The current signs are indicating that the universe expansion is occurring at an accelerated rate. It is still not known for how long this expansion will last, whether it will stabilize and when the decline will start.
The real answer of the question is still unknown. Scientists and researchers are continuously conducting researches and experiments but so far, they have not been able to reach a single consensus.
