My questuon is:

If one person on earth, one person on satellite, both measure the ticking of the clocks,

does 1 second duration appear the same relatively to each of them?

If same, why you say the clock on satellite is slower?]]>

But why (use complex frequencies)? When I studied electronics this wasn't really explained, we just did it.

By observing electrons that have been accelerated to extremely high energies, scientists are able to unlock clues about the particles that make up our universe.

Accelerating electrons to such high energies in a laboratory setting, however, is challenging: typically, the more energetic the electrons, the bigger the particle accelerator. For instance, to...

So, is there anything in the universe will remain at rest forever?

It seems NO.

Because everything is moving.

Given "u" the velocity of A relative to the earth, "w" the velocity of spaceship B relative to A, you should find "v" the velocity of B relative to the earth.

Earth ……………………………….A…………………………………….B

u is the velocity of A relative to the Earth

v is the velocity of B relative to the Earth

x is the velocity of Earth relative to B
