Since 1972 the speed of light is DEFINED at 299.792.458+-0.001, NOT
measured. No effort to measure the speed will be made since then.
Moreover, the meter and second are both defined based on the speed of
light, so no change in the speed of light can be measured anymore!
So how constant is constant and if the speed of light is an
unbreakable barrier is it possible that we can move the barrier itself?
Replace all the electrons in the universe with lightweight
versions and the light should go faster.
