I've been working on some ideas that deal with a discrete nature but
the role of time is very different in this model.
Instead of time acting as a medium or dimension of some kind, time
exists in the context of multiple states.
For example, you have state A. You also have state B. When viewed on
their own state A and state B are timeless, but when analyzed
together, a discrete change of state is viewed as an instant. A
before, an after, and nothing in between.
Similar reasoning is applied to matter and space.
This ideas are *very* difficult to understand unless you are ready to
unlearn everything you know about time and space. But I think the
rewards are clear:
A discrete view of nature that easily explains the most difficult
concepts of physics, such as time dilation and the wave-particle
duality.
Please let me know what you think:
