does an electron move at c

How does science work? And what's all this about quantum mechanics?

ginkgo. we are talking electrons fired from an electron gun at the target.just trying to find out what speed they the electrons go at through the experiment .cos as you know they the electrons go into super position befor appearing on the target as a wave .just trying to find the speed of the electron in super position.

There is a difference between an ensemble of photons and or waves that we call phase and group velocity whereby naively at least the wave front of the photon is supposed to have exceeded c, but if you actually measured each photons velocity they would all be c, but I somehow doubt he is referring to that.

An Electrons speed is generally .99999999999c in a vacuum.

A superposition is merely a way of describing the wave in all it's possible configurations, ie probability amplitudes of the photon being at that point, it is not meant to be a visual representation of the what the wave looks like. Suffice to say I have no idea what you are driving at still, you seem to be a little confused about a superposition of probability and what a wave actually looks like.

Some trajectories of a harmonic oscillator (a ball attached to a spring)
in classical mechanics (A–B) and quantum mechanics (C–H). In quantum mechanics
(C–H), the ball has a wave function, which is shown with real part in blue and imaginary
part in red. The trajectories C, D, E, F, (but not G or H) are examples of standing waves,
(or "stationary states"). Each standing wave frequency is proportional to a possible
energy level of the oscillator. This "energy quantization" does not occur in classical physics,
where the oscillator can have any energy.

so can we then say blags that the electrons that are fire from the gun into the double slit experiment are traveling at .9999999 of c and are at this speed when in super position or entering superposition in the expirement.

cos im interested to know what the speed of an electron is regs c when it goes into a super position.no one explains it they dont ever give that imformation.and im inqisitive.

Blags did explained it when he said a superposition is just a means of explaining a wave in all of its possible configurations.

From your perspective I guess the answer you are looking for is that the wave travels at the same speed regardless of the form it takes.

thanks ginkgo.so are we then going from a .9999999 of c electron speed to a c speed wave function in super position

what i was trying to get at here is the speed of probability .if probability has a speed then it probability is relative and local.the event is made up of entangled probabilitys of movment of energy.consciousness its self how ever must be nonprobable so its the minds interference in consciousness that causes the uncertainty and collapses the wave of probability .

Which is even more confusing there's no speed of a probability, there's a speed of an actual wave. Probabilities only denote the energy concerns in a system at any given time.

Probabilities are neither local or non local they are just information, like I said a probability is not a representation of a real system, it's just a probability, the wave function is not a real pictorial version of the wave, it could be but that presents all sorts of problems.

Don't get me wrong I like people who are genuinely curious about the curious world of physics, but you seem to be curiouser and curiouser. Hell study the subject more it couldn't hurt. Don't have to do a degree, you can learn much of this subject if not all from the internet.

but the energy only exists as probability so probability has a probable speed a probable time space ratio.

No energy exists as a fact, quantum mechanics can only describe it in such a way that is complimentary because we cannot see the wave as it is, so we can only inductively reason a result from the experiment not deductively show what energy actually is and in an exact form, hence any mathematics merely shows that it might be something, but that we cannot know for sure how it appears.

I suggest you look up complimentarity but I would feel I think with your understanding of physics, and no offence, it would leave you more confused than you were before.

Suffice to say there is no way to pictorially represent a function of the wave that agrees with a classical system. And I know that sounds like a cop out, but that is how it is. I doubt reality gives a damn for our fragile classical understanding of reality. :)
