Why? If we have always been right here, then what difference does it make whether space is finite or infinite? We don't care about having to travel at all, much less about having to travel an infinite distance. We were always here.Uh oh, you are not going to like this, but the argument goes for space too, that is if you say an infinite distance in one direction of space.
Well, if space and time are actually unified, then the argument would seem to include space too.
We happen to be travelling along the time dimension as a steady rate; but that doesn't mean that the units of time are passing; we are measuring our progress against them, not the other way around.
Okay, then how could have our frame of reference passed by an infinite number of units; the problem remains.
Nonsense. This wouldn't be true for a large finite number of units, much less an infinite number, unless all possible reference frames are constrained to constant motion in one direction. Can you prove that such a constraint exists?
I have said to others that the argument relies on the postulate that time goes in one direction.
At time now - 13.7 billion, matter starts doing its thing; right now, we are discussing it; perhaps at now + 30 billion matter ceases doing anything interesting. This might or might not be a description of all of time; or of a portion of a larger finite time; or of a portion of an infinite amount of time. How could you tell which?
In a larger interval of time that includes (13.7 + 30) billion years, I will still ask how the event of the Big Bang happened if infinite time came before it. The same problem comes up.
