A few questions,please answer?

Question

Is the Universe Finite or Infinite in size and on other parameters.
Is there a possibility of many Universes.
Is there a possibility that our Universe is just a small part of something else you know Its value may be that of an atom for some humongous creatures (I know its sci-fi movie related concept,MIB 1 ending theme).
Have the scientists found something beyond our Universe.

Answer 1

first, the universe is finite, not infinite. the universe may be something like the two-dimensional surface of a sphere, except it is four-dimensional. the universe has no edge and no center.

second, no one has proved the existence of other universes. it is only hypothetical.

third, no, that is a fantasy.

fourth, nothing, not even space and time exist "outside" the universe. to quote a dead writer, "there's no there, there". space-time itself originated in the big bang so the big bang was the entire universe and everywhere in the universe was once the big bang. the observable universe is only a small part of the entire universe.

Answer 2

Because of the current limits of our technology it is impossible to tell whether it is infinite, although popular belief holds that true. There is a possibility of parallel universes, with many wild theories supporting that such as the string theory. They also suggest that gravity is a "weak" force because the gravitons(theoretical subatomic particle they made up) are being leaked into parallel universes in other dimensions. What is hard is to discern the theories that have been researched, and others that were made up, and popularized, like the String theory. Scientists have not found anything beyond our universe yet. For all we know they might have, although by definition it is impossible to go beyond a Universe.

Answer 3

The shape of the universe is determined by a struggle between the momentum of expansion and the pull of gravity. The rate of expansion is expressed by the Hubble Constant, Ho, while the strength of gravity depends on the density and pressure of the matter in the universe. If the pressure of the matter is low, as is the case with most forms of matter we know of, then the fate of the universe is governed by the density. If the density of the universe is less than the "critical density" which is proportional to the square of the Hubble constant, then the universe will expand forever. If the density of the universe is greater than the "critical density", then gravity will eventually win and the universe will collapse back on itself, the so called "Big Crunch". However, the results of the WMAP mission and observations of distant supernova have suggested that the expansion of the universe is actually accelerating which implies the existence of a form of matter with a strong negative pressure, such as the cosmological constant. This strange form of matter is also sometimes referred to as the "dark energy". If dark energy in fact plays a significant role in the evolution of the universe, then in all likelihood the universe will continue to expand forever.

Answer 4

We can't view anything outside of our universe, so most of your question cannot be answered. It is quite possible that the entire universe exists with a black hole itself, and because we can't look out we don't know if other universes exist. Size may very well be infinite, but we cannot concieve of what just keeps going, but infinite is the theory, if you can go fast enough.

Answer 5

What are you in movies are possible. But if you ask for a proof you wont get any since currently we know only about us.
