I had a dream last night that I went back in time to 1965. Everything was authentic with all the old sweeties and shops etc.
Brilliant dream but thats all it ever will be as no one will be able to time travel EVER.
Stop watching Dr Who Zampa!
Didn't Hawking speculate that matter entering a black hole would be destroyed?
Then there is matter and anti-matter collisions, which will destroy each other
As for time, there is only what was, what is, and what is to be.
