What else can I help you with?
What is All matter and energy that exist including earth stars planets and dust?
The universe.
What happens if there is no stars?
If there were no stars, the Universe would be devoid of the light, heat, and energy that stars provide. This would drastically alter the formation of galaxies, planets, and the conditions necessary for life to exist. The absence of stars would lead to a dark, cold, and lifeless Universe.
Are there 20 planets in the universe?
As of now (late 2013), over 700 planets have been found to exist in orbit around other stars, and more are constantly being discovered.
Does nothing exist in the vast expanse of the universe?
The vast expanse of the universe contains many objects and phenomena, such as stars, planets, galaxies, and dark matter. So, it is not accurate to say that nothing exists in the universe.
Does gravity happen in other parts of space?
Yes; wherever in the universe there is mass like planets, stars of even meteors, there is gravity.
What does atronomy study?

How is the universe not named while the stars and planets are?
It is. It's called THE UNIVERSE. your question was already an answer.
What year that all the planets don't exist?
Probably several tens to hundreds of millions of years following the Big bang. Afterwards, planets formed around stars and became a permanent feature of the Universe.
What is the role of fundamental forces in nature?
They "shape" the universe into being what it is. (Change any of them and we would no longer exist. Not just us, but the stars and planets would be gone.)
Why man is not the center of the universe he is only a part of the universe?
Because - our tiny planet is just one insignificant rock, in a sea of trillions of pieces of space 'debris' - consisting of planets, stars, solar systems, galaxies and nebulae that exist in the Universe !
What is most of the universe?
Nothing...or dark matter.Only 0.03% of our universe are the stars,the planets,the galaxies...99.97% of the universe is nothing...
What if gravity didn't exist?
Without gravity, it is doubtful that the universe as we know it would exist at all. At the very least, galaxies, stars and planets would be unable to form. Worse still, without stars there would be no heavy elements and it is unlikely that life would exist.
