Typically when we think of time travel
Maybe the past is still there ? Maybe time just is. If time travel into the past and future is possible then where are the tourists ?
If as I suspect, Our universe is only one of a myriad of globule universes extruded by the singulrity of a black hole from a previous Universe and expanding into a region of total entropy, I like to call the 'Big Nothing'.
This starts to make sense, if we consider that a singularity is infinitely small, hot, and dense.
Then we can presume that Infinities are the order of the day and it is a cycle of black hole singularity to black hole singularity.
We humans are still very primitive. Our Homo sapien brains are only about 80,000 years young. Which is shorter than a blink of the eye in cosmic terms and we can't rap our heads arround infinities.
