Can other universes exist? Can they have different laws of physics and/or different laws of math than our own universe?
Perchie said:I supect the answer to the OP's question is unknowable.
Jupiter60 said:Hmm. I'm guessing that while different universes could possibly have different laws of physics, the laws of math would be the same in all of them. Two plus two will always equal four, never five.

mrspeedybob said:jackmell, I disagree for the following reason...
Using your analogy of phases of mater; solid, liquid, and gaseous water all obey the same fundamental laws of physics. If the laws of physics that we observe and measure in our universe are different then those in another universe then none of them are actually fundamental laws of physics but rather different manifestations of deeper laws which are universal. (or multiversal) :-)
There is nothing magical or supernatural about the conditions that gave rise to life in the solar system - they can all be physically defined.phinds said:This clearly implies that there is something different about the galaxies and so forth that do not happen to be part of the observable universe. On what do you base that? I realize that we'll never know, but I think it's VERY Unlikely, not very likely as you have stated.

And when you understand that there are 3-400 billion stars in the Milky Way and at least the same number of galaxies in the observable universe, you begin to realize the immense probability of similarly conducive conditions existing elsewhere in the Milky Way alone.
Perchie said:I think the whole question of other universes turns on the idea of there being a boundary to our own
Perchie said:Only because your statement regarding galaxies 'outside the observable universe (OU)' was a non-sequitur. I dispute the possibility of matter's ability to exist beyond the OU.
Wikipedia said:In Big Bang cosmology, the observable universe consists of the galaxies and other matter that can, in principle, be observed from Earth in the present day—because light (or other signals) from those objects has had time to reach the Earth since the beginning of the cosmological expansion.

Perchie said:Regardless of the undisprovability of that statement, the origin and root of the multiverse question lies in the requirement for a where and a when (in human intuiton) for anything to exist ... which conceptually, demands a boundary.

But why all the anger ?phinds said:You will find that on this forum when you make utterly ridiculous, crackpot statements, such as the one you made, you will be called on it. It is not a matter of my feelings, it is a matter of physics.
You would do better to attempt to address the issue of your crackpot statement rather that try to deflect criticism.
Currently, there is no definitive proof that other universes exist. However, some theories in physics, such as string theory and the multiverse theory, suggest the possibility of multiple universes.
At this point in time, it is not possible to travel to other universes. The laws of physics as we know them do not allow for such travel. However, some scientists are exploring the possibility of creating a "wormhole" that could potentially transport us to other universes.
It is hypothesized that other universes may have different physical laws, but there is no way to confirm this at the moment. If the multiverse theory is correct, each universe could have its own unique set of physical laws.
The concept of infinite universes is a subject of debate among scientists. Some theories suggest the possibility of infinite universes, while others propose a finite number of universes within the multiverse.
According to the multiverse theory, there could be infinite versions of ourselves in different universes. However, it is impossible to confirm this without concrete evidence of the existence of other universes.
