Which is the end of expanding universe? If any end exists, what will be behind this end?

Question

For every thing there should be an end or decline to reach a ground state. But the universe is going on expanding. What is the end for it? The existing energy in the universe will be diluted and after some times, vacuums of energy will be created in the universe (energy can neither be created nor be destroyed). If any imaginary end exists, what will be there behind it?

Which is the end of expanding universe? If any end exists, what will be behind this end?

Before we can address that question, we must first define universe.

The word universe denotes all space and everything (matter, energy) contained within it. The prefix uni means one. The root verse means word, carnate message, meaningful substance, matter. Questions regarding our universe persist today. Does it have a beginning and end, or does it go on forever and ever? Is it linear or curved? If it has limits of length or curvature, then what lies beyond the Universe? If something lies beyond the Universe, then can’t we accurately call that the Universe?

Some lay people and some scientists conceive of the universe as infinite space. Others define the universe as finite, or limited (perhaps curved), space. Still others incorporate the elements of matter and/or energy into their definition of the universe, as opposed to the space beyond matter and energy.

Given these concepts of our universe, some scientists conclude that the “totality of space could be infinite. Shrink an infinite space by an arbitrary amount, and it is still infinite. (Scientific American March 2005).”

As to the notion that we live in an ever expanding universe, moving away from every other universe on the fabric of space-time, some scientists are careful to point out that “

Andromeda, our nearest large galactic neighbor, is actually moving toward us, not away. Such exceptions arise because Hubble's law describes only the average behavior of galaxies (Scientific American March 2005).”

In accordance with your supposition that our universe is in another universe, “it has been hypothesized by some scientists that the universe may be part of a system of many other universes, known as the multiverse (http://en.wikipedia.org/wiki/Universe).” Modern astrophysicists talk about multiple "pocket" universes that branch off from one another. Stephen Hawking points out that parallel pocket universes can have no effect on a real observer inside a single pocket, so, according to Hawking, they are theoretical baggage that should be eliminated from cosmology, the study of the origins of the universe.

Some string theories define the universe as a three-dimensional space in an invisible space having more dimensions. This is, in essence, a universe within a universe. Our zone, a “braneworld” could periodically bounce into another parallel braneworld.

This may create what would appear as a Big Bang from one perspective or a Big Bounce of alternating expanding and contracting universe from another perspective. Such a cataclysmic event is thought to occur 300 billion years from now, resulting in the rearranging and creation of a new universe.

Which is the end of expanding universe? That may be determined in 300 billion years, when it stops expanding (like a balloon). If any end exists, what will be behind this end? A multiverse void containing other expanding and contracting balloons, referred to as universes, may exist beyond our own.

Answer 2

There are different theories. Some think that the universe will continue expanding infinitely. The energy density will contiue to decrease as the universe expands. However, there will not be an energy vacuum just a more diffuse spreading of the existing energy.

Another theory suggests that the universe will expand to a certain limit and then start to contract onto itself, like a heartbeat. This will lead to a new 'big bang' as the universe becomes exceedingly small.

Got to head with The Foo Fighters, they're essentially the most interesting band I've ever noticeable in live performance. Plus you'll pass judgement on via the creativity in their tune movies that there could in no way be a stupid second. And can I get dibs on strolling the llama?

Answer 4

''The belief that our wondrous universe could have evolved by blind chance is crazy. And I do not at all mean crazy in the sense of a slangy invective but rather in the technical meaning of psychotic. Indeed such a view has much in common with certain aspects of schizophrenic thinking.

Answer 5

There will be no end. It will expand forever. Everything will grow cold and dark.

Answer 6

the universe will not cease to contine.
just think of rasin bread expanding because you continually add yeast to it. :p

Answer 7

Is there an end?

Answer 8

einstein proved that energy can be created and destroyed.

Answer 9

I think if anyone knew the answer to that question, their head would implode.

Answer 10

i don't understand your question. can you explain in more details?
