Thread: Probability a dimension.

Yes

Isn't that equivalent to the many-worlds interpretation of the uncertainty principle?
So, every time a subatomic particle decays or something, the universe splits into two universes: one where the particale has decayed, and one where it hasn't. And this has happened since the big bang, so basically anything that can exist, does exist somewhere in the "multiverse". A fascinating thread of speculation based on this is Quantum Immortality. Look it up.

Do I make sense?

As hard as this is a concept to wrap my head around, yes.

This is already a pretty famous thing. I'm surprised you haven't heard of it before.


Watch "The Butterfly Effect"

Now the question is, how does one travel along the axis, or axes, of probability?

It's called dreaming.

How does one travel along the axis (or axes) of time? Good question.

Nah, I think the dreamworld would be another set of dimensions all together. Similar to space but without all the physical boundaries. Or something.

Is there more than one axis of time? I thought you could only go theoretically backwards and forwards in time.

You do it every instant of your life. The only problem is you can't "untravel."

Probability isn't really a dimension, but there is an unconfirmed theory that for each uncertain event that occurs (on the atomic level) in fact every possible outcome happens, spawning a new universe for each result, and we just continue down one of them.

What do you think? Is this idea already known by others? Would probability be a single dimension, like time, or would it classify a number of dimensions, like space?

Probability is a model which predicts the long-term effects of uncontrollable factors on the results of a repeated "random" process. When all factors are accounted for, probability becomes unnecessary - collapsing to '0' or '1' in all cases. It is only with the introduction of uncontrollable/unpredictable factors that probability needs to be used.

In this way, probability is a human invention designed to help us cope with our inability to understand all of the factors going into a process. It really doesn't exist outside the human mind, and so it doesn't make much sense to call it a 'dimension'.

What? You don't think that dreams are just vivid hallucinations created by our brains?

why? why every time somthing happened would the opposite thing continue on in another world? Why would this happen?

First of all, this is not what really happens. What actually happens is kind of close to this, though.

Anyway, the theory goes that since at a quantum level all decisions come down to random chance, whenever there are two possibilities, or "roads," the universe splits in two - one universe proceeds down one road, the other universe takes the other possibility.

This multiple universe theory is also used as a way to justify time travel without incurring the "grandfather paradox." If you traveled back in time to kill your grandparents before you were born, you'd only be killing them in another universe, not in your own, and thus not contradicting your existence.
