There was a theory that once the universe had reached it's maximum size, and began to contract, that time would begin to run in reverse. Perhaps recent evidence that the universe expansion is never ending is faulty and all these "reboots" are in fact evidence the contraction has begun. Another theory is that time is a human construct and that all things "past, present & future" are in fact happening all at once ... in which case The Facts Of Life is still in production and being aired ... we don't need a reboot thanks.
