The problem with that idea and what could lead to a hell state for an explorer, is that if you were traveling at an infinite speed, you wouldn’t get anywhere, you would be indefinitlley traveling so long as the universe itself was infinite, for then you would be traveling such that you passed all points instantly but there would be an infinite number of points. Otherwise if the universe was finite, you would simply stop at the end of the universe, but the problem with that is would that stop be so sudden that you were crushed?
And you can’t actually cut all of something away instantly, I imagine that being attempted and all a person ends up doing is just slamming the knife down next to the thing, thus that thing was cut away, from something else, in its entirety. But you can’t say cut something without cutting it away from a part of itself…
The problem with going back in time is that if such was actually done then no matter what you would have altered the future, simple precence alone Butterfly effects to the future, as such even if what you changed didn’t stop you from thinking you should go back in time, it would still change you: You go back in time as a result your a little different then in actuallity when you went back in time you were different and then that difference causes another difference to your future self that then causes another difference to your future self when it goes back in time and so on and so forth, such that ultimatley the simple act of going bak in time would cause an instant loop of alteration in the subject that would result in an infinite rate of alteration, such as to probably nullify it from being able to effect anything…Although it may be possible that eventually you will change to a degree that prevents you from going back in time, but if that happened you would have then effectively never gone back in time and thus everything would be the same…
I would think though with regards to the BB that it is possible that it will seem finite and we might find an end but that doesn’t actually mean that it is finite, because in finding that it was we would be using measurements from within the system that is the universe, and thus it would be like saying the size of an apple is 50/50ths of that apple which ammounts to just saying it is 1 apple, and doesn’t really suggest size…
