Answer
One of the most common errors is that people say there is no gravity in space. Gravity is everywhere, even in space. Astronauts look weightless because they are in continuous freefall towards the Earth, staying aloft because of their horizontal motion.
The effect of gravity diminishes with distance, but it never truly goes away.

Yes, there is gravity everywhere in the universe. Gravity is simply the attraction "force" of a huge ball, or mass of something. The bigger the mass, the stronger the gravity. Astronauts orbiting a the earth are not in a zero g environment, they are actually being pulled toward the earth but are moving so fast perpendicular to the earth that they don't hit the ground.
Gravity is a function of mass, so if there is no mass nearby, there will be no gravity. By 'nearby', I am talking about within several hundred billion miles. The gravity field of our sun extends well beyond the orbit of Pluto, a distance of several billion miles. However, a space capsule in orbit around a body will give the illusion of zero gravity because it is constantly falling around the body it is orbiting. Gravity is constantly pulling the capsule toward the center of the planet, but the velocity of the capsule causes it to fall in a curve. The curved trajectory means that the planet is constantly curving away from the capsule, so it is in 'free fall', and the occupants will have no sensation of weight.
Some gravity afects all space, However if you are in outer space well away from any planets you wil experience what is known as weightlesness because there is so litle gravity you wont know that its there.
Yes there is. In interstellar space there is an attraction toward the center of the galaxy. In inter-galactic space there is an attraction toward the nearest cluster of galaxies. Gravity doesn't disappear with distance, it just gets weaker.
The force of gravity works in the same way but it get much weaker over larger distances.
So, for example if you get ten times further away from something its gravitational pull reduces to 1/100.
Yes.
Yes.
Yes, probably in the upper atmosphere or in outer space.
No they can not operate in outer space.
Yes, gold is from outer space
That depends on what you mean by "outer space". The moon is outside the Earth's atmosphere and therfore "in space" but it is orbiting the Earth and therfore hardly "outer".
yes
Yes.
Liquids can exist in outer space, if they are in an enclosed area, such as a space craft, or a space station. They can not exist in a liquid state in unprotected outer space. Either they will freeze due to the extreme cold, or they will melt (or turn to gas) due to extreme heat.
No, so far we have found no life in outer space. Life may well exist in outer space, but we haven't found it yet.
no
Yes, probably in the upper atmosphere or in outer space.
There is no such thing as "absolute motion" - neither in outer space, nor anywhere else. Motion must always be specified in relationship to some other object.
outer space is a vacuum and a vacuum is completely empty space. however all celestial bodies that exist in space(planets, stars, etc.) do not make up space
outer (as in "outer space")
The word "alien" means "creature from outer space" (among other meanings); pressumably, that would be a species that developed on some other planet. It is not currently known whether such aliens actually exist.
Yes outer space exists We haven't been in space enough to have the answers but there are widely excepted theories. According to Einstein's theory outer space isn't as much held together as it is supposedly sitting on a plane of Space-time. Gravity is a force imposed by matter stretching and bending the space time. Space is expanding so that suggests it is not "held together".
they built it in outer space
