The Sire Universe

For starters with this theory, I want to make it clear that this is purely speculative, and there is no possible way we can test this. I just gathered what I know about the universe and how it supposedly formed according to the big bang theory, and how it will supposedly end, according to heat death. The universe, in theory, was once a singularity, or a point in space with infinite density and zero volume, all the matter and energy in the universe was once in a spot that occupied no space. There are other forms of singularities, such as a black hole and possibly the basic building block particle that has mass; it almost occupies no space. Something caused the original singularity to expand into what is now the universe. Now the theory is that as the universe's expansion accelerates, particles slowly begin to move further apart as gravity and other forces no longer have sway because the fabric of space is getting stretched ever thinner. Space itself exists, even if it is empty. There is a "fabric" of sorts. This stretching of space takes BILLIONS of years. Heat death, as defined by wikipedia, is as follows, "The heat death of the universe is a plausible ultimate fate of the universe in which the universe has diminished to a state of no thermodynamic free energy and therefore can no longer sustain processes that increase entropy." In other words, there is no energy left in the extremely stretched expanse of space and time. I am advocating for a possible theory where, as spacetime is stretched further and further, and particles that were once microns apart are now light years apart in thinly stretched spacetime, eventually all that is left is the basic thing that has mass, which like I said, has the form of a singularity in itself, given how small it is. Now, my theory is that when spacetime stretches almost out of existence, the basic particle's field that contains that energy as mass ruptures and fails, and the energy of that "singularity" expands into a whole new universe at the microcosm. Since there are beyond countless basic building block particles, there will be beyond countless new universes when this one dies. Also, this means our own universe was once the basic building block particle of an old universe like our own an unfathomably long time ago, and the process of death and rebirth has been going on forever. Our current universe has beyond countless brother universes that we can't reach because the fabric of spacetime that once separated our universes has "died" and no longer exists. Essentially it is "dead space," impossible to cross. I call this the Sire universe theory, because every particle that exists is like a seed for a new universe. Have a good day.
