If we look at the distanct 1 meter, you can step from the point 0 to the point 1 in one step. You could argue that in this case 0 is the number just before 1.
If you half the length of your step, you would go from 0 to 0.5 to 1. In this case 0.5 could be argued to be the number just before 1.
If you half the length of your step once again you would go from 0 to 0.25 to 0.5 to 0.75 to 1. In this case 0.75 could be argued to be the number just before 1.
No matter how many times you half the length of your step you would still step on a number just before you get to 1, but the number will depend on the length of your step.
So how would you define the number just before one?
I understand that you find the idea of infinite time in an expanding universe absurd.
But your arguments don't make me see it as a problem.
The distance from 0 to 1 is a finite distance. I don't think it translates well to an infinite 'distance' in time.
If you look at a time line and look at the time between point 0 and point 1, then there would be an infinite amount of points in time between 0 and 1, just like in the distance example.
But the time it takes to travel from time 0 to time 1 is still finite because passing a point in time takes an infinitisimal amount of time. The time between time 0 and time 1 is finite.
Now if you talk about traveling from 'the infinite past' to now, the time we are talking about is not finite.
And I agree that if time behaves like we are used to, then that would take an infinite amount of time.
But we know the universe was very hot and dense when it was younger, and we know that time behaves strangly in such an environment (again:
Gravitational time dilation - Wikipedia, the free encyclopedia ), so I don't think you can rightly assume that time flows in a straight line the way we are used to, when talking about the early, dense universe. So it is possible that there is no time dilemma if one delves deeply enought into how time works.
It is also possible that you are correct that there is a dilemma.
That time goes on forever but the universe (as we know it) had a beginning.
I see 2 ways to deal with that:
- You can solve that dilemma by adding God as you propose.
- You can also solve it by postulating that the universe itself is eternal and what we see as the creation of the universe is just a change in the universe from what it was before to what it is now.
I would argue that both 1 and 2 are the same solution just using different words.
If you add an eternal God before the beginning of the current, finite universe, then together (God + universe) is eternal and what we see as the creation of the universe is just a change in the universe from what it was before to what it is now.
