Does this exist in a parallel universe?

LOL!!\nThat's great.  The clip is running through my mind right now!  It's so vivid it must really exist.

Parallel worlds... Twins of our own that differ only slightly. By events or even natural laws.\nAny thing CAN exist, until it is proven that it can't.\nAs far as the how part of your question, we don't know yet how this world exists. Don't get to far ahead of us or you'll have to come up with your own answers.

Yes, I do believe that life does exist in the universe on other planets. its doesnt mean that life is there only on Earth n in our solar system of the STAR SUN.\nIf u c there r millions of stars in the universe and triliions of planets so there is a possibility to find a planet similar or exact as EARTH which has the same atmosphere or maybe the same gravitational field or perhaps the same solar system is repeated somewhere in the universe.

There are a lot of people (scientists) working on this. A recent documentary I watched showed how they are trying to prove that alternative universes might exist (I think this started with Einstein). If so, someday they might find out how to move between them, which could be a form of time travel. I believe in the possibility of many things that have not been proven.

The multiverse. And current theory states it is possible.

The universe is not actually infinite, although it is unimaginably large - perhaps up to thirty billion light years across with a couple of million galaxies.\n\nHowever, the circumstances that created Earth are quite unique: only we emerged from the particular dust cloud that formed us, only on Earth did a 600 million year old glaciation lead to the pre-Cambrian explosion of soft-shelled complex life of the upper Ediacaran, and only on Earth did an asteroid hitting Mexico's coast clear out the large reptiles in order for the larger brained mammals to take over. \n\nIn short, a very specific sequence of events permitted us. It is almost certain that the exact parallel events have not happened anywhere else.\n\nThat is not to say that there are not Earth-like worlds out there. The Hubble telescope has a new refraction technique that has allowed it to find rocky worlds in other solar systems, and it recently found a world that is somewhat similar to the Earth (but five times larger.)\n\nBut they would not be Earth.\n\nThere is one quantum mechanical derived theory that posits a new universe breaks off with each possible choice we make.  This was the premise of a sci-fi show, "Sliders", at one point. If such universes do exist in a multi-verse, we have no way to detect them or know they are there, unfortunately.

There is certainly no evidence for that, just some very speculative ideas.\n\nEverything that we see - planets, stars, galaxies, cats, frogs - is part of this universe. That is pretty much by definition. Basically anything that we can ever observe is in this universe.\n\nThe speculation about other universes arises from a couple of scientific theories. One is from thinking about what came "before" the Big Bang. (I put "before" in quotes, since the Big Bang was the origin of both space and time for our universe, so it isn't clear at all that anything like our concept of "before" even applies.)\n\nWith these ideas one imagines some sort of meta-universe, from which lots of smaller univerese pop up and form. Some of these form and decay quickly, in microseconds. Others form and become big but nothing happens in them, no stars just some hydrogen floating around. In the lucky ones, such as ours, the universe pops into something large with all the right parameters for stars, planets, capybaras and Lindsay Lohan.\n\nThe second approach comes from an interpretation of Quantum Mechanics which, frankly, few physicists believe. It is not a crank theory though. This is the "many-worlds" interpretation. Basically it says that on the quantum level when ever there is a choice between a particle doing A or doing B the universe actually splits. In one universe choice A exists, in the other choice B. It is easy to see that this would lead to gazillions and gazillions of "parallel universes," some of which are very close to ours but with slight differences. Say, identical except Lindsay Lohan is Emperor of Earth.\n\nThere is no experimental evidence for either the pre-big band meta-universe idea, or for parallel universes from the many-worlds interpretation of QM. (Personally I think the many-worlds interpretation is just wrong, while the meta-universe idea sounds good.) So it's all speculation.

i think there are parrallel dimensions that acctually collieded to create this universe, i saw it on the discovery channel.  Then again Dan brown's "Angels and Demons" sets off the idea that there is another parrelel demension exactly the same as our except everything is created of anti matter, the alternate of matter, therefore once antimatter and matter collide, boom both disapate.  They have been able to create anti matter.  (can you mark this as best answer)

Actually, there has been a proven world out there that is parallel to our own! However, it's not the same concept of parallel that you read in science fiction books. In theory, the parallel world to our world is the exact same, but with a couple of difference. The first difference is that you can't see the parallel world. Also, in this parallel world, it is the exact opposite of ours. That means that when something in our world is positive charge, the world parallel to ours has a negative charge. This phenomenon exist to satisfy the balance of the universe in electrical charge. However, this parallel world can't have support life because it would unstable its atomic structure if it does.\n\nThis a fascinating prediscovery of the secrets of the universe.

the universe is finite yet has no boundaries. it may be something like the two dimensional surface of a sphere.  nothing inside or outside the sphere exists for the two dimensional surface.  nothing exists outside the universe in this model.

the concept of time cannot be just related to this parallel. the creation as a result of a big bang is just a theory, it has not been proven. not having time before the big bang is beyond understanding. however the infinity can be proven (for example the number pi) that in my opinion shows that the creation was pre-planned in someway by a supreme being (a freemason would say).

You might be interested in M-theory of the universe. It suggests that the universe, ie the big bang that we see is the result of two higher dimensional membranes touching each other. Other membranes may actually touch and produce other kinds of universes but with physics that might be unstable or unusual

Ok, the parallel universe theory is a theory that some quantum physicists believe. The reason we have no detected them as of yet is because we can only detect forces and our forces would probably not be able to travel between the dimensions. In one version of string theory gravity is able to travel between the universes. If this is true we should be able to measure small fluctuations from the predicted value of gravity. So far they have tested this ont he scale of tenths of centimeters. There has been no evidence yet that there are parallel universes. If we get better equipment and we can measure that gravity does not follow newtons equation that may prove the existence of a parallel universe. I hope that helped

There could be more than one universe, to assume otherwise is making the mistake of thinking that there are scientific facts. There are only scuentific theories, NOT facts.\n\nIt is possible they could collide as galaxies do, but like galaxies they may simply pass through each other.

I think you have it backwards.  The macrocosm reflects (to a degree), the microcosm.\n\nAt present, no-one knows if there are other universes.  My suspicion (not belief, just suspicion) is that everything that is possible is in some sense actual.  My other suspicion is that nothing is actual at all, so there is nothing to prevent the existence of everything.  Yes, that's a contradiction, but we're allowed to contemplate them once we step outside the bounds of what is knowable.

You have just provided irrevocable proof that wormholes cannot exist which lead back to the same universe.\n\nThanks, thats my entire carreer in theoretical physics out the windows.\n\nYou B*stard!
