It has been suggested by physicists that the speed of light is not constant. That the speed of light was faster in the past, so objects millions of light-years away are much younger than millions of years.
This work is by no means proof its really only a theory right now.
Until I have seen a copy of the paper by Davies et al. I do not know if they have eliminated all other options.
Scientists have also found ways to vastly increase the speed of light. Scientists at NEC Corporation's (NEC) basic research unit in the US have created Laser pulse travels 300 times faster than light.
...it is still correct to say that information cannot be transmitted faster than the vacuum speed of light

Yup.. neutrinos, tachyons (if they exist), lots of em.

The speed of light is about 167,000 miles an hour. Einstein said that going faster is impossible. I think hes wrong. Having studied light theory I think its light that cannot travel faster than that. Of course we are nowhere close to having the ability to prove it. Newtons laws apply most to physics on earth. One thing that applies in space is that unless impeded by something you can go as fast as you want. I would appreciate any insight to why 167,000 mph is the cutoff. As fast as that is I really don’t see why the barrier cant be broken.
TextThe theory of relativity makes sense but still doesn’t explain why light speed is the limit. Thoughts please...thank you..

also since light is a wave you only see light half the time... think of a sine-wave going both positive and negative. now at its peak on both the top and bottom we see light, when it is at zero state there is nothing.
