The universe
The continuous expansion of the Universe, with all Galaxies receding from each other, is the foundation observation. The Big Bang is the computed start point when all lay together. And where physics as we know it is quite insufficient to probe.
We would have to all wear spacesuits. This is because the atmosphere is the border between our oxygen(air) and space. It could be possible though. :)
A troposphere layer of atmosphere is the are that we all breathe. Mesosphere in the other hand has less air pressure and high into space far from troposphere.
We call it droples droples is inncorrect. it is call the hydrosphere.

All of them have stars and space dust for sure.
I believe it is "interstellar". Intergalactic is the space between galaxies. Deep space. Interstellar space is the space between stars, nebulas, and all other objects WITHIN a galaxy.
All of them
We know that "inter" is used to mean between and "galactic" is used to mean something about galaxies.It is common to apply the term "intergalactic space" to refer to the space between galaxies. Scientists once thought that space between the galaxies would be empty indeed, without the dust and trace gasses that exist between the planets. Now scientists aren't so sure.
To a large extent, empty space. But there are also isolated stars and other objects, as well as dust and gas. It seems that the intergalactic gas in a galaxy cluster, though thinly spread, has about as much mass as all the galaxies!
they all are in space?
No, because it will be impossible for the Hubble Space Telescope to map out all 100 billion galaxies in the observable universe.
Yes, though it is spread out very thinly. In many parts of space there is less than one atom per cubic centimeter - the best "vacuum" on Earth has much more than that. Even so, it is estimated, for example, that the thin gas spread out between galaxies, in a galaxy group, has more mass than all the normal matter (i.e., not counting the so-called "dark matter") of the galaxies themselves - for instance, more mass than all the astars in the galaxies.
Yes. Also, the size of the red-shift for all distant galaxies is directly proportional to their distance from us. This means that the space between us and all distant galaxies is expanding. Thus, Einstein's (initial) view that our Universe has been eternally stable in the location of matter must be false. No surprise that he referred to his early view as his "greatest blunder."
Absolutely NOT!Another AnswerThe Moon is in orbit around the Earth, while the Earth is in orbit (with its 7 siblings) around the Sun. These objects are in SPACE. Space is unimaginably large. All the galaxies we can see (and those we don't see), all the billions of stars in each of those galaxies, all the multiple-billions of planets orbiting those stars.... are all in space.
For starters, if there were no separation between two (or more) galaxies, it would be considered a single galaxies, not two or more. The reason matter is clumped together into galaxies at all (with separations in between) is because of gravity - gravity tends to do that, i.e., to clump things together.
Not all stars belong to galaxies. Galaxies collide, and this process strips stars from their parent galaxy and hurls them into intergalactic space. The Hubble Space Telescope has detected a few hundred very bright, orphan, stars between the galaxies in the Virgo Cluster. Although stars most certainly form inside some collection of matter such as a galaxy, their history after formation can include being ejected from a galaxy and becoming an orphan star.
