>>11920093The thing is, he is comparing lightwaves to waterwaves and this is a very tenuous comparison. It is true that in water, the waves are not caused by the actual mass of water traversing horizontal space, but rather by transferring energy in the water, in which the mass of the water just goes up and down. On the other hand, lightwaves are waves and a particle, which is why they have no need of a matter medium, just the fabric of space itself.
I think that it is not correct to say that light does not have a speed. The light itself is physically moving across space as photons, and it is moving at C. Hell, even if we were to reduce light to waves moving through space and ignore their particle nature, therefore making them more similar to the energy transfer of waterwaves, it is still small minded to say that it has no speed. Waves in water have a speed. If a tsunami is travelling towards a landmass, you'd better believe that the people there will track the "speed" of the wave.
In summary, the person you are replying to is a massive fucking retard.
