I don’t believe in infinitesimals.
Then doesn’t that make the discrete units continuous? What then is the difference between a series of consecutive discrete units of time and one long continuous stretch of time?
We’ve been over this.
You know what else has no scientific proof? GOD!
I might as well say: no there isn’t!
But I’d prefer to address the reasoning behind the assertion. Care to do me the same favour?
What part of don’t imagine a starting point did you not understand?
That’s fine and dandy with me. So then you’re invoking the static picture of time. It’s like a 4th dimension akin to the spatial dimensions. Therefore, there should be no problem understanding it as infinite in both directions just like space.
Time dilation doesn’t prove a thing, except that things slow down the faster they move through space relative to an observer. If you don’t have time, you still have motion and change.
Yes, it was once real–but back then we called it the present–once it becomes the past, it’s only a memory. Cause and effect, change in general, can be understood as always in the present. It is the mechanism that governs change and how it unfolds.
