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/U... 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.

When the universe began, it was smaller than the tiniest particle. But all of the energy contained within forced the space between the proto-matter to expand. as the universe cooled, materials formed over millions of years. If you picture the surface of a globe, a man walking on the top cannot walk off of its surface. The universe is the same, except in 3 dimensions instead of 2. This is difficult to imagine, i know. Scientists can use radio telescopes to see 14 billion light years away; the universe started about 14 billions years ago. and since light travels at a fixed speed, looking 14 billion "light years" away is equal to looking at the "baby" universe. This is how they can tell what things were like back then. Mostly just SUPERHOT proto-particles.. Once again, as the univers expande, the particles condensed and had more room to cool and stick together.
But remember the Globe analogy.
Hey, Read Stephen Hawkings Illustrated " A Brief History of Time" and the sequal "The Universe in a Nutshell"
You will thank me!
Luck to you in your discoveries!

I am just going on what ive been told and heard. How true it is, is up to you to decide. Much like your question.
Their is no endpoint to the universe. Points are used in geometry and while geometry is a vital strain of the universe, it is not at all the universe's whole. The Universe cannot be though of as a entirely spatial relm because there is data readily available that shows that the universe does not behave according to our terms of "space" You can't travel from one end of the universe to the other. You might be able to go to McDonalds and head home again but not out there. Deep Questions....read into it more if you want

No time soon, but there definitely is.
The sun is a star, so eventually it will go through this process:
First like all stars, it will swell up and become a ginormous star, bigger than it already is. When this happens the earth will overheat because the sun will be way, way too close to the earth. Everything will shrivel up like raisins.
Next, the sun will explode causing a massive burst in energy. This will probably result in the planets being knocked out of their respective orbits.
When that's over, the sun will be gone, and the Ice Age will be started over. Things can't grow without the Sun.
It'd look like scientists said it did billions and billions of years ago.

Actually the universe with its galaxies is a space with dynamism, stars and planets dies but the remnants of gases and solid particles from these dead system recycles itself creates blackholes with unimaginable forces and tends to produce powerful fusions of chemicals and gases (bigbang theory) that gives birth to new planets.... so therefore this process is a cycle and a cycle has no begining nor the end ....watch STARWARS hahahaha

There is no end. The universe is finite but with out boundaries. just like there is no end of the earth that you can walk off of, but it is still only so big.

there isn't an end to the universe, there is an "Edge" though, because the universe is constantly expanding in all directions, and some scientists believe that one day it will collapse into itself

im shure there is an end to this universe
but yet it beyond our wealth and grasp at this time.
someday after were gone maybe.
thats why we have a space program
