no its not the absolute referance space is only a medium just like water and air through wich energy travels and with each discovery comes a new barriar remember space is not empty in fact it is full, every thing that exists in the universe does so in space

The speed of light in a vacuum can be seen as the absolute reference because observers will always see it as the same value, whatever their own local frame of reference.
You can be on Earth, on the Moon, in a rocket on the way to the nearest star, or streaking along at nearly the speed of light, you will always measure the speed of light as being the same thing relative to you. Take a measure, slow down, then take another measure, it (the light) is still going at exactly the same speed relative to you (even though you have slowed down).
It is this fact (plus some other things) that pushed Einstein to formulate his theories of Relativity (Special and General).
According to earlier versions of relativity, speeds were additive from one system to another. So, if you are on a train moving at speed x and throwing a ball forward at speed y, while on a planet moving in the same direction at speez z, then the total speed of the ball, as seen by an outsider, should be x+y+z. Therefore, light that was emitted from that train at speed c, should appear to an outsider, as going at speed x+c+z.
Yet, scientists were observing that the speed of light always appeared to be the same (c), whatever the speed of the source or whatever the speed of the receiver (or any combination). Therefore, it looked like the universe did not like the old version of relativity.
Einstein created one where the speed of light is the absolute reference frame. His theory makes predictions about other things (like gravity, time, black holes, etc.) and they all seem to work.
So the universe seems to like the new relativity better. This does not prove that it is 100% true. It just proves that it is far more useful than older theories which were based on "common sense".

No, absolutely not.
There is NO absolute reference frame. The fact that all frames observe the same result for the speed of light means it is useless for selecting an absolute frame,

The unvierse is increasing at quicker than the speed of sunshine. particular relativity dictates no longer something can go via area at quicker than the speed of sunshine, yet when area itself expands, there are not any limits on how straight away 2 gadgets can bypass faraway from one yet another. there is the idea of an observable universe. If the universe expands on the speed of sunshine, then there'll exist gadgets that are sufficiently distant that their relative velocity is quicker than the speed of sunshine. The results of it really is that any photons they emit in our route will not in any respect attain us, presented the enlargement retains (which the most present day documents exhibits this is going to). in spite of if lets go back and forth via area at quicker than the speed of sunshine, it truly is forbidden, the universe would properly be countless. A fundemental belongings of the universe is that on tremendous scales, that is homogenous and isotropic (ie. it seems a similar in each position, and it seems a similar once you look in each route). it really is supported strongly via the CMBR radiation observations that are isotropic to one area in 10000. This theory signifies that there are not any favoured factors- no "part factors" to the universe.

well, i dont think so because i read before that the speed of the light was made faster by some scientists who gave the light some energy! so the speed of the light might not be constant in the universe...

Wow, interesting collection of answers... I tend to agree with
most of your respondents, that the speed of light is our only
common reference point at this time. It is fairly well understood
and many large distances are expressed in Light Years (and some in AU).
Kindest regards,
Zah

I think so because energy relates directly to its square which has got to say something. Exactly what, I dont think anyone is exactly sure, but it is probably something like the "frame system of the universe"

It's always going to be a reference until somebody finds something that travels at a faster speed then that.

yes, nothing can go faster than the speed of light.
