It empowers you. To the degree that you have it of course.

faith empowers us to cope up with life.

billions of years ago, space is denser than the present time.
so the constant c may be a little less than what is now today because of the resistance of a denser space.

as space expands in time, it becomes less and less denser, and c may go higher than the present constant value due to a less resistant from a lighter density of space.

so c is always constant but not its value.

Space density is constant ... the cosmological constant ... but matter is moving furthur apart, so the density of overall mass is decreasing being the same mass in a larger space.

In the past mass density was greater than space density, but mass density and space density are almost the same now.

If light enters a denser medium than space it slows down, so if space density happened to decrease c would increase, but time would also contract to zero at that speed

It isn't 'thought moves faster than light', thought is massless so it moves at c, which actually means it is everywhere at once, but c isn't a speed it's a constant and at c there is no distance.

Richard Feynmann: I know why all electrons are all the exact same charge and mass.
Scirntist: Really, why?
Richard Feynman: There's only one electron.

The constant itself is not a quantifiable thing, so we just call it speed.

This is true Gem :) , no matter what speed you or an object are doing, the speed of light ( 3x10^8 m/s) is always just that, thus a constant.

What is interesting to note however is the light speed theory. Time slows down as you approach the speed of light. thus time is relative. a body moving will experience a slower time than a body in rest.

very interesting topic

if a particle disappeared here and then later an identical particle appeared somewhere else and if there is no actual event or state of affairs from which one could learn if the particle appeared later was the same particle or a different one .... Does the question "is it the same particle or a different one? , have an answer?

imo, the question is meaningless.

I don't know about that, if it does make sense it's a good question though.

there is only indeed one thing, but electrons should be thought of as one of its properties and not the thing itself.

these properties should constitutes this whole one thing rather than think of them as parts that constitutes the whole.

I think of it in a completely different way.

If depends on how you look at it

The fact that we think of god, can say that god in some way shape or form exsists.....

In terms of light.... everything is moving the speed of light. It just depends on how close you are to objects. Its relitive to your position. You cant tell things on the earth or in us are moving that fast, because we look from the inside looking out. If we look from the outside looking in ( say at stars or galactic movements), we can actualy see this.

As far as the photon is concerned everything moves at the speed of light, that's why c is constant, but at light speed there is no distance/time, which is why it ain't a speed.

Then as light takes no time to travel the photon is at all places, moreso everywhere at once and in any place, so where we are it looks as though the light from the past is arriving, but from the photon's view everything is arrived.
