The infinite uviverse?

Question

What do you think about the universe? Does it have an end? How about the "multiverse"? Does it have not only end...but beginning :)? Is the Big Bang the reason for eveyrthing or it is just a phenomenon that occurs in the infinite space and time?

I think that the Universe has no beginning and end...it has always been there (Yes I mean the entire cosmos not only what we see and call "universe). I don't know however about the Multiverse ideas, they sound like a science fiction to me.

Thanks :)

Answer 1

The many proofs that have shown that the universe began in a big bang proves that the universe has not always been here but began about 13.7 billion years ago. These proofs include observations that show the universe was smaller the farther you go back in time. We have also detected the radiation left over from the big bang.

As for the Multiverse, that is a conjecture that comes from string theory. This theory has yet to be proven so the Multiverse conjecture is unproven at this time, also.

Answer 2

The universe IS NOT infinite. Something with infinite size cannot expand, and we KNOW the universe is expanding.

The multiverse is a product of one idea to help solve the quantum measurement problem. There are other possibilities (instant wave function collapse for example). So the multiverse theory may not even be correct.

It basically allows for multiple universes to exist to fit all possible outcomes. In quantum mechanics, if an outcome is possible, it must be carried out, assuming the multiverse theory is correct. There would be as many universes as possibilities, so there would be quite a lot, but not infinite.

Answer 3

I think M-Theory is the most logical view to currently have on the existence of the universe. One of the possibilities of the multiverse theory is that new universes can spawn from microscopic regions in an existing universe. This new universe would expand and be full of energy, just like ours is theorized to have done, in the Big Bang.

Our universe is still expanding, and most likely will continue to do so indefinitely. As of yet, the cosmological constant, which defines whether or not the universe will expand forever, perfectly balance itself out, or stop expanding and then start contracting leading to a Big Crunch, has yet to be determined. I personally think that the universe will try to expand forever, but will eventually be used in the creation of a new universe, as it collides with another p-brane in the 11th dimension.

I was never satisfied with what they taught me in school, that the universe is infinite, and to just accept it. Infinity is nature's way of saying you're wrong. There's a bigger picture out there, we're just too small to see it.

Answer 4

Thinking logically: If you attempt to limit the size of the Universe, by definition: everything that is out there . . . (everything !) . . . . then there must be a wall at the edge of it limiting our space. If there is a wall, the wall must have two sides and therefore there must be something on the other side of the wall . . . more space! The Universe includes space, right? So to say that space is limited, means there is something solid at the edge of where space ends. This is a paradox that cannot be resolved no matter what book you read!

One theory that some Quantum Mechanics experts support is that there wasn't just one big bang, but lots of little big bangs, like the edge of our known universe bumping into another universe's edge, causing multiple bangs, as it were. If 'our' Universe is contained, say inside a big glass sphere like a snow globe, then why can't there be many other 'snow globes' out there?

As our universe expands, as is the current theory, then it has to be expanding into some space, right? Again, we aren't creating space, but we are moving into it.

No matter how you slice it, the Universe cannot be contained.

Answer 5

I think that in order for something to exist, it must have a beginning. For example; you can't exist without being born first. It's the same thing for the universe, it cannot exist without something happening at its beginning (the Big Bang in this case).

Now the ending of something is a different story. Something might end or it might last forever, same with the universe.

There are basically 3 theory for might happen to the universe in the future:

1.) If the speed of the expansion is greater than the amount of mass in the universe, then the universe will expand forever.

2.) If the speed of the expansion is equal to the amount of mass in the universe, then gravity will catch up with the expansion and the universe will stop expanding, but it won't collapse.

3.)If the amount of mass in the universe is greater than the speed of the expansion, then gravity will catch up with the expansion and surpass it, forcing the universe to collapse on itself, called the Big Crunch. This will lead to a never ending repeating cycle of the universe.

No one knows for sure which of them are true, but through recent discoveries, I believe that the 3rd theory is most likely to happen.

Answer 6

One day the universe did not exist and sometime in the future it will go out of existence. Infinity is a mathematical concept,yet no matter how high the number a leap to infinity is just the same.
An infinite universe would be a perfect universe and it could not be a quantum entity.
The quantum effect of an imperfect finite universe is what makes us what we see and experience to-day.
The only infinity is if an incident happens goes out of existence and never happens again,the nothing state would be infinite.

Answer 7

I think the universe has always existed and is limitless. My reasoning is, if it hadn't always existed, why and how did it start? No fact based answer is known. Even if the our universe has boundaries, what says there aren't other universes beyond our? The multiverse idea is just an idea for now. The Hadron Collider project may be able to shed some light on that grey area soon.

Answer 8

The universe is composed of matter, energy, space, and time. What you are talking about here is mostly space and a linear concept. There is really only one moment in time and that is right now..Present time....the universe is like the inevitable agreement reached among different viewpoints or awareness units. mechanically you could express it as a dot in the center of an expanding sphere.dependent entirely on awareness of and agreement with its mechanics. The data I have on multiuniverse is that mechanically it is not factual.
Point being that each individual has his own perceptions and that must be there for the universe to exist for him at all.
It is not necessary to understand the exact origins of the universe or awareness to solve it's problems. Really the awareness of awareness unit has no location in space or time, no mass,no wavelength..and only ..is..true static..not infinite..that concept is only possible in the physical universe..not outside of it ..possibly exterior to the game.

Answer 9

the universe is not infinite. you need to educate yourself with some reading on scientific works and learn things like the accelerating expansion of the universe, the cosmic microwave background radiation, elmental abundances, and other evidence for the big bang theory. a good book i would sugesst is "The Whole Shebang" by timmothy ferris. or any of his books, they are all very thourough and straightforward to understand. good luck!!!!!!!!

Answer 10

If you travel into the universe you will one day come back to the same place.
Look at the world from a snails point of view.
Now look at the universe from your point of view.
