Does space exist?

Question

May sound silly but, is space made up of
a)quantifyable parts or
b)completely empty and essentially non-existant?

Presumably answer A signifies a finite universe surrounded by event horizon and B signifies that only matter is finite within a potentially infinate\reoccuring arena?

Does anyone know or are we all just spouting crap?

Answer 1

Nobody knows for absolute fact what exactly "space-time" itself is. However, "empty" space is in fact not empty. Particles and anti-particles pop up out of nothingness and annihilate each other continuously. This has a measureable effect that is predicted by Quantum Electrodynamics (QED) theory, known as vacuum polarization. It has been measured to 18 decimal places, so the current understanding of the theory means that space it not "empty" but filled with this chaotic foam of particle creation and annihilation.

Answer 2

If someone could answer that question and convince the masses that they are totally and irrefutably correct, they would become national figures overnight. Space, in its truest from, is only quantifiable by what limits its horizons ..... myself, I believe that space is totally infinite and without constraint ... and that this planet is by no means the only source of safe haven for mankind. History repeats itself in so many ways and I think that life exists throughout the universe at many different stages. The trouble here is making the human brain actually conceive any of this .... it actually hurts the brain, doesn't it? Truth is though, that there is so much more to life than we will ever know. Try working out how the human body was engineered ( for it truly was ) or how little we know about the depths of the oceans and you will see just how insignificant the need to qualify space is. To exist daily, we need simple choices to be made, like what will I have in my sandwiches tomorrow? Now is that spouting crap?

Answer 3

No one really knows at this point--it has not yet been determined if space is indeed "lumpy" or smooth. String theory postulates that at a small enough distance scale, i believe around 10^-34m, space does break down and is in fact lumpy. A consequence of this would be the dispersion of light: instead of moving at the speed c in a vacuum, high enough frequencies of light would actually travel at a slower speed. Light at this frequency has not yet been discovered unfortunately :(

Answer 4

Once you get on this one, you have to ask whether infinity exists. Is there any end to the Universe and if so what exists outside that. Wanna fry your brain with that one. You would be better off asking yourself if there s life after death.

Answer 5

Speculation..and crap! If our universe is bounded in the same way as a black hole is bounded by its event horizon, then all its interior properties and the existence of these properties themselves would be entirely determined by the surface properties. eg for a black hole temp and entropy are entirely determined by surface grav field intensity and area resp, so its interior properties may as well not exist.
So we could be 'inhabiting' a universe whose very reality was determined and 'projected' by the properties existing on its boundary.

Answer 6

Yes it does, because space is not what you think, but is in fact full of sub-atomic particles being created and destroyed. A sort of quantum foam is the best way I can describe it. It's everywhere, even inside atoms!

Answer 7

scientists belive that space is made up of dark matter and not that there is just nothing there. the fact that they don't know what the dark matter is and haven;t bee nable to get hold of any suggests otherwise but there is still notable evidence to prove dark matter

Answer 8

Does anyone watch The Sky At Night? It's a well good programme.
Patrick Moore is a legend :')

Answer 9

No space does not exist - all made up!

Answer 10

It does not exist. This is not crap.
