No. It is space itself that is expanding.
The universe is commonly defined as all the time, space, matter, and energy that exist. It does not make sense to ask how something exists outside of what exists. If something exists, it, the space it occupies, and the time it exists in are all a part of the universe by definition.
when liquids freeze they expand so if you freeze anything in a full can or bottle it will have no space in which to expand and hence the can or bottle will explode. If you're freezing anything you should make sure there is space in the top of the container for it to expand.
I assume you mean the oscillating Universe. That refers to the idea that the expansion of the Universe will eventually revert, the Universe will contract again, all the matter will get together into an extremely small space, but from there it would expand again (and again, and again...). In practice, this still won't make our Universe last forever, due to the Second Law of Thermodynamics (entropy can still only increase!). In any case, the current observational evidence is that the Universe is expanding faster and faster - not slowing down - so the oscillating (cyclic) model is not very likely.
Dead Space: Downfall is an animated horror movie in the Dead Space universe. A second movie called Dead Space: Aftermath is soon to be released.
The gas was in space from the beginning of the Universe - the Big Bang. Eventually, gravity pulled parts of this gas together, to make the Sun, as well as other stars.
We as humans currently do not know for sure what the exact size of the universe is due to technological limitations, and the universe is likely infinite in space. However, we do know how far we can see into the universe. From our vantage point on Earth, we can observe objects up to about 46 billion light years away, proving that the universe is in fact quite large! As mentioned above we do not know really how big the Universe is. However, in recent years, using methods not even conceived of until recently, it is fairly certain that the time since the Big Bang which is the beginning of the Universe as we know it is very close to 13.7 billion years. This has come from the WMAP satellite which measured the Microwave Background Radiation which is the remnant of the original energy release from that incredible explosive beginning of the Universe. Now that would normally mean that the Universe should not be more then 13.7 billion light years in any direction. This seems to be what we are seeing when we look out into the very limits of the Universe using our best telescopes in space and on the ground. There is a possibility that the Universe could be much bigger then that as the Big Bang theory requires a brief period of "Inflation" were the expanding space of the Universe had to travel much faster then the speed of light briefly in order to make all the observed consequences of the Big Bang theory come to pass. This could expand the whole Universe well beyond the limits of the time involved. So far this has not proven to be the case. Yet space can expand faster then the speed of light. Remember travel in space is managed by the "Higgs Field" which limits travel to the speed of light. Whereas space itself can expand faster then the speed of light as there is no restriction in how fast space itself can expand, it just requires an enormous amount of energy which was available for only a short time immediately after the Big Bang occurred. That means within quintillionth's of a second.
While less than 5% of the universe is made up of atoms, hydrogen and helium make up 98% of the atoms in the universe.
There is no reason to think so. However, we have no evidence to make a conclusion either way.
Measurements of Doppler shift indicate that nearly all of the galaxies outside of our own cluster are moving away from us.
It really doesn't make sense to talk about a constellation being inside or outside the Milky Way. A constellation is, roughly speaking, a general direction in space. This general direction goes all the way to infinity... or however far our Universe goes. There are objects in this general direction both within and outside our Milky Way.
space, or the universe, has no defined shape it is constantly expanding, as everything gets farther and farther apart When it comes to the universe the size and shape are undefinable, unless you get into really hardcore theoretical physics that make sense only to Stephen hawking
The Universe! Initially everything was crammed into an infinitesimally small point but since the Big Bang all the matter and energy that make up our Universe has been expanding outwards.
