Space... What is it?

Question

On earth you dont see air but its there

But in space there isnt air and i just wanna know what else is in space.. is just gases? i mean what is in the empty part of space... i find it impossible for there to be nothing but also impossible for there to be anything...

Answer 1

The final frontier.
You can see air if you want to. You can certainly see the effects of air on a windy day; there aren't invisible beasts who are shaking all those trees.
Space is very close to a perfect vacuum. You are talking about something of the order of atoms per cubic meter of matter in space.

Answer 2

Oh I'd love to answers this one: So far science HAS proven that electrons and other particles can and do spontaneously form in an out of existence. Every particle has an equivalent 'virtual' particle following it at every instance within the vaccum. You know, you should read "Holographic Universe" by Michael Talbot. In it, he talks about how the electron is but a ghostly image of a vast realm hidden 'within' and so far beyond our own. One day, science will prove or disprove whether there are many more finer forms of this multi-dimensional reality (or corresponding light) stretching across empty space. K-theory already suggests that there are 10 dimensional spheres known as Calabi-Yau manifolds located within every point in space. I for one believe.

On the other end of the spectrum there really is no place, no space and no time. Talbot's findings seem to support the Buddhist's view that Existence is eclipsed by reality. (Reality being the vaccum). There was a study done by Feynman and Wheeler which stipulates an electron traveling back in time can overlap with another and appear as one; meaning that there is no (foreseable outer) distance and every element in a system is a cosm of the whole. These particles curl back in on themsevles before they has a chance to differentiate into material existence or give rise to space. In it's brodest context, the electron exists within the vaccum and the vaccum exists within the electron, again reiterating corresponding eastern beliefs dont' you think? I love how Talbot put it: if you have an aquarium with a fish being recorded by cameras, each recording would take place at different angles and any outside observer would think it is being taken of different entities. However, by spinning the fish around, any outside observer would finally realize that all pictures represent the same object. Such is the conclusion with empty space: space and matter are really two sides of the same coin. They can be likened to the black and white stripes on a blow fish if you will, even if there are both 'phantoms' of a higher reality. I believe he used the term quantum potential to describe such occurences.

Now down the nitty-gritty. Many scientists theorize that even you take every bit of matter and energy out of vaccum, freeze it to absolute zero you would just still end up with what's called zero-point energy. ie. If you swing a pendulum and let it unabated it for an immesurable amount of time, you would think it would come to stop? Not so, according to quantum mechanics. Even an atom once it reaches it's lowest temperature will keep jiggling around for as long as it exists.This zero-point energy field, although unmeasurable is still subject to the laws of quantum mechanics. ie. In one cubic center of this space, one finds an energy equivalent to 10^94 grams of matter.

Answer 3

I'm a physics and maths graduate, and I used to think that old-fashioned philosophy was crap. I've changed my mind. Philosophers ask the question; if empty space is just nothing, then why is there a difference between the few cm. of empty space between the filament in a light bulb and the glass envelope and the 4 1/2 light years of empty space between here and Alpha Centauri? Space isn't just nothing: you can measure it in km. and it makes a difference. There's a difference between the 400 000 km of space separating us from the Moon and the 2 million light years between us and Andromeda. We now know that it's even more complicated; it contains energy and virtual particles popping into and out of existence.

Answer 4

Space is the 3-dimensional surface of 4-dimensional space-time. Space-time is the medium in which all matter and energy exists, sort of like wave-crests. Think of it as a pool of water. The suface is the world we see, with light and other forms of energy existing as waves on the surface, since waves on actual water represent kinetic energy. The analogy can be extended numerous ways. Matter would be like soliton waves or bubbles, I can't decide which, in any case trapped by the physics of space into stationary structures. Dark energy is like the depth of the pool, representing the total energy in empty space, and putting an upper limit on the maximum wave amplitute (no greater than the distance to the bottom of the pool). Since energy represents amplitude, the depth of the pool would represent the total potential energy of empty space. Fine, I'll leave.

Answer 5

There is some space dust, etc., but mostly just a vacumn. Nothing.

Yes, that's right, the final frontier is nothingness!

Answer 6

Too hard for me to understand but all I know there are golds
and other metal rocks plentifully out there for us to mine it. These materials mean big $$$ on earth. lol.

Answer 7

look inside. Your head. that is space.

Answer 8

SPACE IS THE OUTER FRONTIER
