If the information is correct, [See related question] then there are more stars in the Universe.
There is an estimated 100 billion galaxies in the observable (note observable) Universe, and say 100 billion stars per galaxy.
This gives a total of about 10,000,000,000,000,000,000,000 stars or 1 x 1022 or 10 Sextillion.
It uses thruster engines. Every action has an equal and opposite reaction
No. There is no currently no need for guns in space. Modern firearms would also be a bit inefficient due to the fact that every action creates and opposite and equal reaction (i.e. recoil would suck in zero gravity).
If you didn't wear a space suit in outer space, you would be exposed to the vacuum of space which would lead to the air being sucked out of your lungs and your body swelling up due to the lack of pressure. You would lose consciousness in about 15 seconds and die shortly after.

By forcing out gas in the opposite direction at high speed. Every action having an equal and opposite reaction.
It would take a lot of money because you have to pay for every thing to be able to survive and get to outer space.
There are 500 white blood cells to every 1000 red blood cells (or you could say there is double the amount of red blood cells). The answer would be 200 red blood cells for every 100 white blood cells.
If 1cm equals 10mm, then 50mm has to be equal to 5cm. Every 1cm is equal to 10mm. If it was 10cm then it would be equal to 100mm. Does that explain it? :)
earth
Are you asking why the missions were performed (exploration) or why rockets move (every action is balanced by an equal and opposite reaction)?
There are 12 inches for every foot. 4 feet would equal 48 inches.
