Do you think there is one world or no there are many worlds from physics sience view?

Question

Can we have another worlds from phyisics sience view ?
please explain...

Answer 1

Many world interpretations only occur when you choose the mathematical technique of perturbation theory to solve the equations of quantum mechanics. Other methods (admittedly less commonlyused) do not give rise to the issue at all.

It seems staggeringly unlikely that the universe changes its behaviour depending on how you do the maths, so to me it is pretty clear that many worlds interpretations have no real physical significance - ie they cannot occur in reality.

Answer 2

I'm guessing you are referring to the idea of a parallel universe. Either that or you mean are there other planets (this of course has already been proven). As for parallel worlds, I have not seen specific physics based data indicating that it could be possible. More correctly, I don't think that humans are currently intelligent enough to comprehend alternate timestreams. What form of energy would be used. Or, do we just believe that the total amount of energy we get from the sun is all the sun puts out, and instead puts exactly the same amount of energy out for each parallel world.

Science in space deals more with the absence of data that the presence. For instance, a planet would not be visible and yet the absence of direct light from a star could tell us that there was a planet there, depending on the size of the non-information area, how it moves, etc.

Answer 3

It's not clear to me exactly what you are asking. If you are asking if there are parallel worlds and realities, quantum physics suggest that there is. For example, in quantum physics, matter is both a particle (mass) and a field (wave-function). Matter is either or, until measured or even observed. If, for example, when we make a decision to "act" on something in our lives, from that point on all other possibilities, wave-functions, collapse and are no longer excessable to us again in exactly the same fashion as at that specific moment in our timeline (space-time). In essence, we create our reality by selecting "one" specific course of action while collapsing all other infinite possibilities (wave-functions), thus parallel worlds.

Answer 4

If you meant our earth by world, we have many star systems, galaxies and one universe. If you meant to ask whether we have more universes, no way of knowing, but there is a theory that we have an anti-universe for our universe.

If you go by the theory of strings (branes), there could be multiple universes. I am not very sure about the theories.

Answer 5

Einstein said that another universe is possible to exist where the physical laws could be different than those in our universe. He was talking about tachyons, particles that travel faster than light, this would be possible in another universe.
