Jzz, you need to read my post on the impossibility of any traveler chasing the speed of light, much less catching it, and why it is impossible.
Atlan0101, Before I read your post on chasing the speed of light, which I would like to do, I should put my own point of view forward. Everyone is familiar with Neils Bohr’s meticulous and strenuous work to map the emission and absorption spectrum of the Hydrogen atom. It was meticulous, it was reproducible, it was calculable. But then, it was pointed out that the electron was a charged particle, and as such being in an accelerated state around the nucleus, it should in theory radiate away all of its energy and fall into the nucleus in something like 10 pico seconds. What does this mean? No atoms, no matter, no earth, no solar system, no Universe! It was in order to solve this seemingly impossible problem that wave-particle duality was introduced. (in a very large degree due to Einstein). It was assumed that the electron within the atom existed in a smeared out state around the nucleus. So, here is the first article of faith, a particle having measurable mass becomes a wave, whose mass and energy is in a ‘smeared’ out state around the nucleus. Then we have the incoming light, what is it particle or wave? Since light on its journey to the atom is in a wave like state (i.e., obeyed the inverse square law) it has to be assumed that at the moment it enters the atom that it assumes a particle like appearance, with an exact location and energy. Thus it is assumed that light travels as a wave and arrives as a particle! This is the second tenet of faith, that a wave at the exact moment it is needed assumes an exact energy and location concentrated in one place. Next, the two, the electron and the photon collide. This is the third tenet of faith, not only does the electron turn particle like at the exact moment it is needed but also ‘absorbs’ the energy of the particle like photon at which point it has to recoil off the massive nucleus. This is the third tenet of faith. How can one wave recoil off another? OR how can a particle recoil off a wave? Whatever the answer, it is a physical impossibility. This is the fourth tenet of faith. Next the electron emits a photon of the exact energy that was absorbed. By now there have been so many acts of faith, that it is difficult to keep track. What I am getting at is clear, modern physics is more an act of faith than any religion. Furthermore, unlike religion which is split up into different sects and religions, modern science is a single modular monolithic faith that is defended by fanatics.
But you say “It is a theory that works!” BS! It is only the empirical part of QM that works, not the esoteric part detailed above. None of it works, there is no explanation for the propagation of light; no-one can explain what radio-waves are or how they form and propagate, no-one has a lucid explanation of electricity in a wire or magnetism or gravity. It is a massive hole in physics.
So faith plays a huge part, and while the speed of light might not be attainable, there are other more mundane reasons for why this might be so, than the arcane theories that so many people have complete faith in.
