The same goes for space. There is material in space. Its just mind bogglingly dispersed; a few atoms per cubic meter. The presence (or absence) of this material can be measured.



However, that's not the way you measure desity. Don't let inifity trip you up. Think about in more finite terms. Does half an apple have half the density of a whole apple? Of course not, the whole apple has the same density as half the apple (just twice the volume and twice the mass).



Answers are generally supposed to make sense. Either you're a lunatic or you didn't comprehend the question. You're not Douglas Adams, you can't get away with 42 being the meaning for of life, the universe and everything.



Right. So space must have an incredibly low density. The density of space must be lower than that of the earths atmosphere. An asteroid hurtling through space doesn't burn up, but will vaporize (unless its huge) upon hitting earths atmosphere.



I take it you're not particularly familiar with comets. The tail of a comet always points away from the sun. When a comet is moving towards the sun, the tail is behind it like the tail of a rocket. However, when a comet is moving away from the sun the tail is pointing ahead of the comet.



No. You can look at the stars without your eyes burning out because, with the exception of the sun, they're all several light years away. The closest star system, Alpha Centauri, is about 4.2 light years away. A light year is a bout 9.5 trillion kilometers, hence the closest star is around 40,000,000,000,000 kilometers away. At that distance your eyeball is a tiny fraction of an arc second of degree. There just isn't enough light to do any damage. Its has very little to do with there being any matter in the way.



Why call it weight? Why not use normal terms to describe pressure? You seem to be saying something akin to "Blue is a word I use to describe taste. Therefore you don't really see colors, you taste them."



The force my face would feel has a lot more to do with the elastic property of the latex in the balloon than the pressure on it.

Speaking of balloons, you never answered my previous question about balloons. You say that the stars and planets are held together, not by the pull of gravity but by pressure from "space". It must take a lot of pressure to hold a star together. Say you take a normal latex balloon and inflate it at sea level. Now, move the balloon into "space". Would be balloon be compressed by the same pressure that holds the planets together? Or would the balloon expand from a relative lack of pressure?



out of curiosity, what was your degree in? If it was liberal arts, this thread is somewhat understandable. However, If it was in one of the hard sciences, I'd ask for your money back.
