How is electron formed? Why does it travel?

In summary: The electron has enough kinetic energy to make the mass of the neutron from the mass of the proton and electron.2) The atom is unstable and the nuclear charge is big enough to hold the electron.The creation of an electron-positron pair requires much more energy than the creation of a proton-antiproton pair (because the proton is more massive than the electron).The likelihood of an electron sticking to a proton is very low, unless the proton is highly ionized (e.g., inside a pulsar, where the electric field is extremely strong).Btw, when you said destroyed, you meant naturally right? B/c they can easily be destroyed if they meet their anti.By "naturally," I

So if it would be true, that would basically turn relativity upside down. Which means we would have to find a new theory that explains all those classically unexplainable effects which (special) relativity predicts in great detail.

But you should note the following. The relativity principle is often misquoted as "nothing can go faster than the speed of light". Actually, this is wrong; e.g. the phase velocity of a wave can exceed c, and the EPR paradox is an even "worse" example - in that the transmission is instantaneous.
The relativity principle states that "the speed of light (in vacuum!) is the same for all inertial observers" and what people who say the first quote really mean, is that no information can be transmitted faster than the speed of light. For example, studying the cases I mentioned above more closely, reveals that they cannot be used to communicate instantaneously in any way.

Yes, but group velocity too (anomalous refraction). What carries information is signal velocity, which is < c.

, and the EPR paradox is an even "worse" example - in that the transmission is instantaneous.
In EPR paradox superluminal action is just one of the interpretations, not a fact.
