The cyclical universes

These ancient theories of universes that were born, destroyed in an apocalypse and other universes re-emerged are born from philosophy and mysticism, but they have a modern scientific version, which is known as the oscillating universe, a hypothesis proposed by Richard Tolman according to which the universe undergoes an infinite series of oscillations.

Each of which begins with the Big Bang and ends with a Big Crunch or great collapse, this would mean that the Universe expands for a time before the gravitational attraction of matter produces a reverse process until everything collapses again in a singularity and a big rebound occurs.

That is a cyclical model so our universe would be just one of the infinite universes that happened before and those that will happen after and here we come to one of the headaches of scientists, the infinite and that is that the infinite in the infinite many things happen, in fact they all happen because it is infinite, if ours is just one more in a line of infinite universes it means that in the past, we are going to use the past and future time scale as we normally understand it, because talking about time would also be to give another topic Just talking about time.

This would mean that we would have universes with small variations, some would be universes similar to ours and others would have variations in the same laws of physics that would make them very different, there would be universes in the past with the possibility where life would have arisen, perhaps universes where life had better chances of emerging and were more habitable than ours and other universes that would only be a meaningless cloud of particles and radiation.

The question we all ask ourselves is how to communicate or how to travel to one of these universes. If we were really living in this type of cyclical universe that ends up being destroyed in a collapse and a new one emerges, there would be some possibility of traveling to another universe. speculates that some black holes that already exist in our universe may come from previous universes, because they may be able to survive the Big Bounce process and therefore may have valuable information about what happened in past universes and about the entire cyclic process. of the formation of universes.

This could explain one of the problems and headaches of scientists since we are currently finding, thanks to space observatories such as Hubble or James Web, that in the youngest and earliest universe there are supermassive black holes and of course it is not explained how they did so. to grow so quickly, but the point is that to make a trip to another Universe of the cycle we would need a ship that reproduces the characteristics of a black hole and that inside we manage to almost stop time.

Some works claim that the great collapse could occur in about 22,000 million years, so if we want to appear in a future universe at a time similar to ours we should add about 13,700 million years, if we want the trip to be a duration of one day that would mean slowing down, sorry, slowing down time inside the ship to a scale of one second, which would be equivalent to 43,194 years on Earth.

In 3 and a half hours we would see the extinction of the earth and the solar system and at the end of all that time of that day that we would spend in which 35,700 million years would have to be spent, we would not have the guarantee of emerging in another solar system because that The new universe might have some variations from ours to the previous one, we could emerge in a different universe or a universe formed only by radiation and dispersed particles. That would be the cyclical multiverse model, multiple universes in the past and multiple universes in the future in a cycle. constant creation and destruction.
