Can we travel with the speed of light? -Of course since we are made of light, the only question is what would be the dammages on living matter. The most important question is where would we land if we move with the speed of light, on the moon, under water, or under the earth. Since everything moves in the universe our traektory is very hard to be calculated. It exists also the so called melting of matter. The evidence of that is the Phyladelphia Project: some human beings on this ship which in fact was turned into light through strong electromagnetic field have melted into the non living objects on the ship, because all humans and ship where moving in the environment, sometimes nearing themselves so much that in the form of light they have incorporated each other when turning back to matter. Another property of light and all corpuscules is the electric charge. The bigger corpuscule the bigger positive charge, the smaller corpuscule the more negative charge. For example neutrons are the heaviest, because their mass is the sum of proton and neutrino. Neutrino has a neutral charge and is lighter than protons, but heavier than electrons. Light has different charge from less than +1 until more than -1, and electrons are -1 and have a mass that is fast equal to absolute 0. So if we connect the mass to electricity charge in a diagram neutron would be the heaviest, near it would be the proton, in the middle between proton and elecron would be the neutrino, than comes infrared light, coloured light, ultarviolet light and in the end would be the electron with charge of -1 and no measurable mass. Does this mean that the absolute Nothing has a negative charge? -Yes. I has negative charge and is at the temperature of abslute zero(−273.15 °C). Does this lead to the conclusion that there is an endless source of energy in the universe? -Yes. A proof for that are the lightings, they occur in a place where the temperature is very low and in a vacuum environment and they fall on Earth because it is positive charged. I know I do not have the knowledge to prove this, but it sounds more logical than all theories until now. So give my theory a try
