Only two things are infinite,
the universe and human stupidity,
and I'm not sure about the former.
We can make finite state machine.
Probably the universe is a kind of infinite state machine.
For example, a virtual counting machine 1 ÷ 0 ＝ ∞ asserts a form of the universe.
This means the time unit is 0.
The universe is the non-inverted transition process of energy.
Time is a unit of energy.
Existence is a unit of energy.
In 4-dimensional space, I call each of them Phenomena.
I don't know why electro-magnetic wave exists.
But they are the same in nature, that is a transformation of energy.
Why space exists, why energy exists?
I don't know, Only God knows!
