Where are the other universes?

[EvanEjk]

I think that there might be other universes, but the laws of physics still apply.

I and another member of this forum proposed a parallel anti-matter universe to reinstill symmetry. And anti-matter works just like matter, just an opposite charge.

i voted other to demand of this thought of explanation

in the grouping of form there is a a connection out of the group ... it has no boundaries so seemed in space or past or future. One steps one way or the other and each path is a new universe that is there. The belief is from having gone back and been visited from forward and connected to in the present. in going back i have influenced the past to the change i do not return to as mine is written, from the future I have let my steps be guided and found great reason for this to have been done, over and over to where i asked it to end and it would not, still does not, no explanation of how nor why till the event horizon is over ... have none of you ever gone with the flow or gave up your will to go with the feeling beyond self logic of why or how? It is a thing all can do, try it and proof will follow as only truth can be, acceptable to self by what you are made up of ... and each time you take that step its a new universe you have entered and the door ways are many as are the windows, ... there are no no walls except your own closed eye,
That is my thought value or not an given, enjoy! ~ Peace Graham

Not only is there just one universe there couldn't possibly be any universe other than this one.

Why do you say that? Do you have proof of that or is this your opinion?

The use of the word proof is a little strong but I might be content to say yes.

I could just present it as a theory and then let you falsify it. I can verify the existence of this one universe.

To prove the thesis false you will need to prove the existence of another universe or show me with conclusive evidence that this universe could exist in some different way than it does.

[Profpat]

You are wrong sir.

You are the one who as a statement of FACT said there is one universe. Where is your PROOF to that statement. Rather I believe it is your OPINION. I never stated that there was more than one universe, I'm just open minded to the possibility. I don't have to prove that to you.

Maybe a little research is in order for you.

Parallel Universes

Author:

Max Tegmark
Abstract:

I survey physics theories involving parallel universes, which form a natural four-level hierarchy of multiverses allowing progressively greater diversity.

• Level I: A generic prediction of inflation is an infinite ergodic universe, which contains Hubble volumes realizing all initial conditions - including an identical copy of you about 10^{10^29} meters away.
• Level II: In chaotic inflation, other thermalized regions may have different effective physical constants, dimensionality and particle content.
• Level III: In unitary quantum mechanics, other branches of the wavefunction add nothing qualitatively new, which is ironic given that this level has historically been the most controversial.
• Level IV: Other mathematical structures give different fundamental equations of physics.

The key question is not whether parallel universes exist (Level I is the uncontroversial cosmological concordance model), but how many levels there are. I discuss how multiverse models can be falsified and argue that there is a severe "measure problem" that must be solved to make testable predictions at levels II-IV.

I would strongly recommend you view Tegmarks site and others regarding this matter before stating as fact something you believe to be true.

Best,

If I am wrong then you can prove to me the existence of those other universes.

The existence of other universes is only conjecture... not fact. If you are so insistent that other universes exist then it is upto you to prov eit.

I have proved one exists. If you think there is more than one then the ball is in your court.

Why conjecture the existence of a whole boatload of universes to try and explain some difficulty in this one?

[Profpat]

I'm not going to waste my time discussing this with you further. I never stated that there was more than one universe, rather I'm open to the possibilty of that.

I think we both agree that there is at least ONE universe but that does not prove that it is the only ONE, only that there is at least ONE.

Good day sir,

Pat

I selected “parallel” as my response as the best available choice. The selection of “curled up within ours” is virtually as descriptive as my selection. A hyper-dimensional string or brane based TOE seems to be the best thing being worked on now. Attempting to “locate” and point at the other dimensions within our limited view of and description of space-time is a futile expenditure of energy. Therefore, attempting to do the same regarding the “location” other hyper-dimensional universes is equally futile.
