Expanding
No. The sun only appears larger than other stars because it is much closer to us.
People are obsessed with space, moons, stars, the universe, etc. because they love Science. Humans are naturally curious creatures, it's in our biology. The Universe is something that we have not fully understood and probably never will. Thus people will forever being fascinated by the stars and space because we know so very little about it.
Stars are scattered all across our universe but guess what? there are no stars in our solar system besides the sun!
The Universe.
Are we guarding them from what? People have yet to seriously get off our own planet, so, no, we are not doing anything with stars.
A galaxy contains billions of stars. A universe contains billions of galaxies.
All stars and galaxies are in the universe.
Why stars "burn", and the size of the universe.
The Universe.
What i think is that its doing both at the same time. You see the universe is constantly imploding and exploding in many ways. Stars explode yet the particles of the explosion implode and help form other stars. Now we can take this information and think of it in many ways. Is the universe constantly expanding to the point in which it will become to much for itself and eventually implode and then explode into what we call the universe today. Even steven hawking said that "The universe is ever expanding and what he theorizes is that eventually the universe will grow so much it will implode or continue expanding. but as we see with the stars we constantly imploding and exploding we could only assume the same of the universe
Stars do not belong to a planet. They belong to the universe.
We haven't observed all of the stars in the Universe, so we don't know what is the largest yet.
