if there is another universe like owers why carnt they find it?

Question

i allways beleived that ower universe is not the only on as there has been life here before so some where out there there is i think that poltogists and angles that people have seen are from another plannet but have advanced technolegy to use stelf mode meaning they can travel among us with out being detected but now and again it fails that why we can see them now and again

Answer 1

My understanding of the parrallel universes, which i dont believe in but assuming the theory is right, is that they exist in alternate realms. So think of trying to find them is like trying to find God. One idea on how we might find one is if we tear the fabric of space. Again, i dont believe that this is possible either.

Answer 2

I am not sure what you mean by Universe. IF you mean our galaxy which is what we call the Milky Way then there are millions of other galaxies out there that we can see and of course there are millions of stars in our galaxy. However it takes light 7 hours or more just to get to the edge our solar system and the nearest star to our sun is 4.5 light years away so the distances are so vast that it is extremely unlikely that any species on another planet similar to ourselves could reach us within their own lifetime or several lifetimes. So I would forget aliens moving amongst us.

Douglas Adams - Author of "The Hitchhikers Guide to the Universe" and "The Restaurant at the end of the Universe" amongst other titles, had the explanation.

Elevators. Most of the time elevators go up and down, but after a while they get bored with this and decide to go sideways, of course it's physically impossible for them to do this, so they have managed to do this inter-dimensionally. That is why it seems to take forever for a lift to arrive sometimes. The extraterrestrials have managed to harness this phenomenon and that is why they can move between dimensions. I was stuck in an elevator once that decided it was going to time travel to see the battle of Hastings in 1066. After a lot of banging on the buttons, the elevator relented and took me back to where I wanted to go. But I had lost an hour in the process. That was my explanation to my boss for being later anyway.

Answer 4

Well the explaination of your question deals more with our own universe (where all known planets, galaxies et cetera exist).

But why we can't find another universe is in part because we are not advanced enough in our technology and understanding of science, but even more so because even if it was there, I don't think we could see it.

Our universe has it's own rules that govern every part of it from how stars form to how humans see. We are bound by these rules and therefore bound to our universe. Rules, dimensions, worlds outside of this universe would make no sense to us and, I think, be indetectable.

It would be like hearing a language that has absolutely no connection to yours. You could never learn it; it would always sound nonsensical... there are no common roots to words to go off of and there is no key connecting it to languages that you know. What's worse here is that we can't percieve it because it is not spoken or shown.

Answer 5

THE idea of multiple universes is a surprisingly attractive one. Two deep problems would go away if the universe were not, in fact, universal, but were merely one example of an infinitely large class of such objects. These problems are the true nature of the uncertainty principle, and the “anthropic principle”—the coincidence that the universe seems to be set up with precisely the right conditions for human-like life to evolve within it. Unfortunately, the sorts of “multiverse” proposed to resolve these two problems are different.

The uncertainty principle was developed as part of a way of thinking about quantum theory that is known as the Copenhagen interpretation, because it was orchestrated by Niels Bohr, a Dane. Heisenberg was one of Bohr's students. But there is an alternative, first proposed in 1957 by Hugh Everett. This is that the universe does actually behave in the deterministic way that 19th-century physicists thought it did; it just looks uncertainly probabilistic. For this to work, however, it cannot be alone. Instead, each event that happens spawns an infinite number of parallel universes, and, taken together, the various versions of the event in question happen with the probability dictated by the uncertainty principle.

At the time, most researchers rejected Dr Everett's explanation as being even harder to swallow than the Copenhagen interpretation. But it has been taken up in the past few years by David Deutsch, a researcher at Oxford University. Not only does Dr Deutsch believe in Dr Everett's parallel universes; he thinks it might be possible, in a manner of speaking, to collaborate with them.

The universe-straddling machines he has in mind are called quantum computers. Primitive versions of them have now been built and enthusiasts, Dr Deutsch included, think they could become a mainstream technology in decades to come.

An ordinary computer works by manipulating “bits”—binary digits—of data. These are either one or zero. A quantum computer manipulates “qubits”. In the Copenhagen interpretation, their values are indeterminate until an observer attempts to examine them (if he does, the uncertainty “collapses” and he is left with an ordinary, non-quantum bit).

The result is that lots of calculations can be performed in parallel, as long as their intermediate steps remain unexamined. So a quantum computer with a given number of qubits is more powerful than an ordinary computer with the same number of ordinary bits. Indeed, the number of possible calculations goes up exponentially with the number of qubits. In fact, it would not take a particularly large quantum computer to perform more parallel calculations than there are elementary particles in the visible part of the universe, let alone in the computer itself.

Dr Deutsch argues that the computation cannot, therefore, be happening in a single universe. Computing is not an abstract process. The information being manipulated has to be associated with something physical. The only possible explanation, he thinks, is that the separate, parallel calculations are being done in separate, parallel universes. In other words, the different, parallel machines in the different, parallel universes are collaborating.

Answer 6

Imagine there are beings out there, and they are at the same level of intellignece as us, and they are millions of light years away.
Because the universe is so vast and the speed in which light, or radio signals travel at a known speed, if we look or listen in their direction, we would see/hear the way their planet was millions of years ago. They would not hear our radio/tv signals for millions of years to come.

Answer 7

They probably can and already have. Why make contact and have to contend with the stupidity of the unevolved human mind. All they need do is sit back long enough and we will destroy ourselves. Until the common goal of humankind is to unite and explore the stars, we will never live long enough to meet other inteligent life or explore the vastness of space and all its' wonders.

Answer 8

because it would take over 1 million years to reach the next galaxy (andromeda i think it is). it would be impossible (unless a super rocket that travels faster than the speed of light is found). even then, i doubt a human lifespan would be anywhere near long enough. besides the whole human race could be gone by then...

Answer 9

Who is to say they already haven't found us (not necessarily recently but also many many thousands of years ago)?

Answer 10

There are other Universes just like us , but people cant find it because it is millions of light years away from us .. And maybe when we reach it it will disappear , or we will find it is too late , or mayeb too early .
So there you will find same particles with other shapes Like our sulphur isnt their sulphur .. well that needs alot of explinations ..
