It is going to replace the Hubble Space Telescope in the year 2018. It will study the edges of the universe, where the light from the creation of the Universe is still in transit to the Earth. So what JWST will do is to look at the past, billions of years ago, when the Universe was only a few hundred million years old. This would help us understand more about the evolution of the Universe.
The Big Bang Theory presents the theoretical premise for the causation, termination, and continuation of an evolutionary expansion of the universe. The Big Bang promotes that the universe is Time bound (or has a finite existence), that the universe is expanding (within the dimensional limits of Space and Time), that the universe is evolving a set amount of matter and energy while it is expanding over time, and that the universe is homogeneous and isotropic with respect to Space and Time.
Sure. Why not. There could concievably be a universe vastly different than this one. Of course. As universes get the hang of being universes, they propagate space (probably at the speed of light) as they go. Read about Membrane Theory for some interesting perspectives on what things were like prior to our "Big Bang".
According to scientists and technology, the structure of the universe seems to be round and flat, so the space can be bent. Another theory would be round and very spacious. Really, no one knows for sure.
The problem is - we can only speculate on the origin of the universe - based on our limited knowledge of the bit of space we live in ! There are literally billions of other galaxies out there - with hundreds of billions of suns and planets. There could be many other rules of physics & chemical elements that we just don't know of ! There's just no way of proving how the universe started (or whether this is the first ever universe !).
The universe contains space and time. "Outside" the universe, there would be no space or time, and without these, nothing can exist.
It would be the universe since the universe refers to the whole world!
space
as far as we know, we live in 3-Dimensional space which encompasses everything in the known universe. there is space in any dimension, so you can't get out of space, or you would not exist. if you mean run out of space, then something as large as the universe that would use up most space would probably turn into a black hole anyway.
Possibly, except the universe would either have to cease to exist or the situation couldn't be here before such a situation would come to be. Space and time are branes in our dimension and for a point to be no-space-no-time, it would have to exist outside of our dimension.
it would be a piece of mass....roaming in the space(universe)
astronauts always go into the universe to search for life and also if we did not have any we would not know much about space
While there is matter in the universe it will not be able to reach absolute zero
That would be the distance from one edge of the Known Universe to the other. As the Known Universe is believed to be approximately 15 billion years old, that would be 30 billion light years in diameter.
The Universe appears to be dark because space (meaning nothing), contains no matter for the sun to shine on. Also, another reason is that the universe is so large that, if you were to even try to look at the edge of the universe from outer space, the light would not exist beyond a certain point (because of the measurement of lightyears, and the never ending radius of the universe that is expanding). Thus, the universe is black.
Stellar space, from planets, moons, asteriods to stars, galaxies; The Universe basically
If the world were flat (as is the universe), how much space would it cover?
