would uncertainty allow a particle, from the probability of existing outside this universe?

Question

i mean would a particle from this universe be restricted to this universe or could it have a probable existance outside it?

Answer 1

Of course, your thought experiment is highly speculative. I favor this view:

Before the Big Bang, the universe was completely empty and consisted of three infinite spatial dimensions, but no time. At the moment of the Big Bang, time began. I believe this is so because time is an essential component of energy and the energy of the Big Bang is the origin of all the matter in our universe. The wave-front of the Big Bang has thus been propagating away from its origin at the speed of light, since the beginning of time in this universe.

At the quantum level, it is well known that virtual particles "pop" into existence from the "vacuum." It is also known that the vacuum is not entirely empty. Even with no particles or energy present empty space still has measurable properties, namely permittivity and permeability. Maxwell and others originally thought these properties proved the existence of the aether, but we now understand they exist because pure space does not exist in our universe, we can only observe spacetime.

Your question really asks, where do virtual particles go when they pop out of existence? Do they leave our universe? Alternatively, you could also ask, where do virtual particles come from when they pop into existence? Do they come from outside our universe? I suspect (as in guess) that virtual particles come from and return to a timeless version of our reality. A place where space exists but time doesn't. Although this place is actually part of our universe, we just can't detect it because to do so would require energy (see uncertainty principle) and energy can't exist in the absence of time.

What do you think of that?

Answer 2

there are various theories, however the common one today seems to be like that there isn't something outdoors the universe simply by fact by using definition the universe is each and every thing, so if there have been something previous what ever boundary you formerly defined on the universe, then your previous definition replaced into fake and you may now incorporate that element interior the hot universe paradigm. Then if there have been something outdoors that your defintion is back incorrect. So the two there's a bounded state which incorporates a finite quantity of universe (Ie you may draw a field around it and say it somewhat is the universe) and each thing is interior it, or there's a limiteless state the place no mater the way you draw your field you probably did not get the universe simply by fact whats outdoors the field continues to be universe. the undertaking consisting of your question whilst utilized to those theory experiments is that for the time of the two case your question is beside the point. In case one there's a conflict of semantics, by using defining there isn't something outdoors the universe so asking whats outdoors the universe is like asking what isn't something? by using definition not something isn't something yet even it is complicated. simply by fact we've not any way of describing not something. The vacuum of area, a black countless room, a white countless room, a number of those issues are something and there for not not something. interior the 2nd case there's a logical errors on your question, simply by fact if there is not any real thank you to entice the field without violating the definition of the universe the how are you able to ask whats outdoors?

Answer 3

Current string theory hypothesizes 11 dimensions. But, they are what compromise's the actuality of our universe. Therefore, to answer your question, the uncertainty principle would allow a particle whose existence is in one or more of the dimensions, to exist, but it would have to alter form to be perceived in our four dimensional space-time. No particle could exist outside of the 11 dimensions.

Answer 4

The theprectical graviton (the mass-less particle that gives the quantity of gravity) according to some flips in and out of our universe. They beieve the gravity is too weak a force and should be greater and they believe it is becuase it is split between our and other universes.

Answer 5

Depends upon the scope of the space or universe you were trying to introduce it to. If it were similar to it's original space then yes, if there were extra-dimensional forces involved then probably not.

Answer 6

Since its part of our universe and obeys the physics of our universe, it's destined to stay here.

Answer 7

The homeopathic practitioners would believe that it has existence outside it.
