rethinking… midpoint of infinity

Well, now, as it turns out, I think my last attempt to cover this topic was a success only in making a mess of time and space. They are separate, so I am told. Bundling them all together so haphazardly made my thoughts quite a bit more convoluted than they had to be. Since this issue has really been bothering me lately, I’m going to tease things out a bit more here. Things may seem disorganized at first, but all that follows is on the same line of thought.

So, if time itself were infinite, then would right now always be the midpoint?

If time had a speed limit, it seems like it would be set by the speed of light – since that sets the limit for everything else.

Time itself may be setting the speed limits.

I take issue with infinite divisibility.

Because most things in nature cannot undergo such a division.

From here, we can see that nature gives us lower bounds on the size of things.

Time is a natural thing, right?

What is it made of? That usually determines the lower bound.

Can time exist without motion?

If not, then maybe time is made from movement – and more reason to take light as a possible limiting factor.

If so, then what might it be made of?

It won’t do to say time is made of seconds, etc.

Assuming that some class of particles x were the smallest in the universe. Then might that set a limit on the smallest movement?

We line up these x particles in front of some thing y, and we move y. on the line We know y moves because it displaces an x. If it doesn’t displace an x, do we still want to say that it moved?

If not, we have discreet steps of movement. Lower bound is the size of x.

There is nothing actual about a fraction of an x then.

Likewise with time?Eventually, there is nothing actual about a division…

Then things tick along in small steps, not in an infinite number of steps.

Infinity would be unnatural.

But is that how it is? Do these bounds exist?

I’m not sure things are any more obvious, but maybe my train of thought is a bit easier to follow. I’m going to be back here soon. If I can ever get there.
