Main Question or Discussion Point

Is it fair to say light speed will never be reached because the energy required has been dissipated or used during the big bang...?

How do you know there was enough energy to do that during the big bang in the first place?

No, it would be fair to say that light speed will never be reached because the energy required would be infinite! And no finite region of the universe has ever contained infinite energy.

So is it fair to say...Infinite to a point.

No, it is not "fair" to say that unless you have a specific reason to. Can you cite any of the cosmological model that would justify such a view?

No matter how much energy you have used to accelerate yourself, even all the energy in the universe, you will still measure the speed of light in all directions to be the same as it was before you started. Then if you could do it over and over again, as many times as you wish, you'd still be right where you started from in terms of getting any closer to the speed of light.

So, no, it's not fair to say that the reason you cannot reach the speed of light is for lack of energy.

How about Moffat's theory

Please cite the exact peer-review reference of your source.

Yes it is fair to say but you need to prove!

Light speed of what? There are plenty of particles in the universe that are already traveling at light speed.
