Are there functions which would map space to relatively smaller regions that could give us a different perspective on our universe? For instance, what would a starmap look like with each region of space scaled by its gravitational flux?
According to [1], the pressure inside the LHC is somewhere between 10^-11 and 10^-10 mbar. That's between 10^-9 and 10^-8 Pascals. CERN also says that it's "a vacuum almost as rarefied as that found on the surface of the Moon." According to [2], pressure on the surface of the moon is between 4x10^-11 and 8x10^-10 Pa. The upper limit is quite close to 10^-9 Pa, so let's say that CERN can manage 10^-9 Pa on a good day.
According to [3], the inside of a nebula is 100-10k times more dense than general interstellar medium. (The "10k particles per cubic cm" figure also comes from the same page.) According to [2], interstellar medium in the Milky Way averages between 10^-15 and 10^-14 Pa. So the pressure inside a nebula should be between 10^-13 and 10^-10 Pa. Another comparison using the number of particles per cubic cm [3] yields a figure between 10^-14 and 10^-12 Pa. The difference is probably due to temperature, but anyway both results are significantly less than the LHC.
We can probably make better vacuums on a smaller scale, though.

He had read of 'Space': at the back of his thinking for years had lurked the dismal fancy of the black, cold vacuity, the utter deadness, which was supposed to separate the worlds. He had not known how much it affected him till now-now that the very name 'Space' seemed a blasphemous libel for this empyrean ocean of radiance in which they swam. He could not call it 'dead'; he felt life pouring into him from it every moment. How indeed should it be otherwise, since out of this ocean all the worlds and all their life had come? He had thought it barren: he now saw that it was the womb of worlds, whose blazing and innumerable offspring looked down nightly even upon the earth with so many eyes-and here, with how many more! No: Space was the wrong name.
