What else can I help you with?
What are 3 possible outcomes of the universe?
1. the universe continues to keep expanding 2. the universe slowly stops expanding 3. big crunch (basically the universe will stop expanding and fall back into itself)
Is there is space outside universe to make it expand?
No. It is space itself that is expanding.
What is happening to the universe since the big bang?
Since the Big Bang, the universe has been expanding. Galaxies are moving away from each other as space itself expands. This expansion is happening at an accelerating rate, driven by dark energy.
How vast is the universe really?
It depends on exactly what you're measuring. The vast majority of cosmologists (that is, essentially all except for a few kooks) think that the universe is expanding. That, coupled with the speed of light, means that the most distant objects we can see appear to be at the distance they were from us several billion years ago, and since the universe is expanding, "now" they are further away than that. The observable universe is a sphere around 28 billion parsecs in diameter. The observable universe is itself expanding with time. However, for complicated reasons the observable universe (that part of the universe we can see) will eventually stop expanding, at a diameter of about 38 billion parsecs. Anything outside this distance is moving away from us faster than the speed of light (because of the expansion of space itself), and its light can never reach us. For details, please refer to the link in the "Related Links" section.
If were in space then what is space in what is space expanding into?
No one knows for sure. There are theories, but absolutely none of them can be proved, and I doubt we will ever find out. The universe is expanding firther into what was here before the big bang. Basically, nothing. The universe isn't expanding like a balloon blowing up; the universe is already there, but the objects inside it are spreading out constantly (black holes, stars, galaxies, etc.) The universe isn't expanding; the objects inside are spreading out within it.
Does your universe rotates around itself?
Yes.
Why it seem to see the sun rotating around the Earth?
because earth is rotating around itself while revolving around the sun
What is the largest thing that moves around in circles?
Technically, there are entire galaxies that "orbit" around one another. There are super galaxies called "Giant Ellipticals" around which smaller galaxies move about. The problem is that it becomes a question of relativity, as in, what is the center of the universe (or is there even one?) or what is revolving what. There are some theories that speculate that the entire universe is rotating or "moving around itself".
How is the space itself expanding?
The space itself is expanding due to the continuous stretching of the fabric of the universe, causing galaxies to move away from each other. This expansion is driven by dark energy, a mysterious force that counteracts gravity on a cosmic scale.
What will happen after this universe destroyed?
There is no reason to believe that the Universe will be "destroyed" - it will continue expanding, and at some point there won't be enough free energy left to support any type of life, but the Universe itself will continue existing.
