When we say 'outer-space'

Question

Are we really meaning the space we have detected with our instruments (as far as they have seen/reached) and is then true 'outer space' the area that has not been detected - be that the area we assume (?) that space is expanding into ?

Answer 1

no, all of that empty space out there. detected and non detected

Answer 2

As I gather it's any area outside the influence of gravity.

Answer 3

In general terms, when I was a child growing up in the age of space exploration, "outer space" was a term used to refer to space outside and beyond the solar system and our local neighbourhood group of planets.

Nowadays, people seem to use it to describe anything outside the Earth's atmosphere!

Answer 4

i read stephen hawkins 'a brief history in time' and 'the universe in a nutshell' they are both great books with mind boggling facts but they really just confirm the fact we have'nt a clue about alot of s**z and but do have alot of theories.  

Answer 5

Outer space is just a term to described a physical space that is not taken up by a planet.

Answer 6

'Outer space' begins about 200 km above the Earth, where the shell of air around our planet disappears. With no air to scatter sunlight and produce a blue sky, space appears as a black blanket dotted with stars.

Answer 7

No.  Outer Space is a cultural, not scientific term, meaning everything above the Earth's atmosphere.  And outer space doesnt have a hyphen.  

There is interplanetary space, interstellar space, and intergalactic space, all part of 'outer space'.
