comment How do moving charges produce magnetic fields?
For magnetic field production, you need acceleration, not uniform speed...

comment If the universe didn't expand faster than light, would our nights brighter like day?
@Jim Even correct figure can be jot down in terms of billions. It's really not a matter here.

@Jim billions is a rough figure. It's correctness isn't a matter here. And, despite we can receive CMB, it doesn't mean lights from all Stars have reached us. Universe has grown since production of CMB (classically, faster than light).

The accepted answer isn't addressing your mass issue. See my answer..

comment Why no longitudinal electromagnetic waves?
Then, can EM waves be longitudinal in plasma?

comment Can parallel universes constitute the missing mass aka dark matter?
Dark Matter isn't the missing mass. It's the excess mass.

comment Do particles keep on emitting energy?
The question of whether accelerating electron emit EM wave or not is a classical question. In modern theories, acceleration of electron can't be defined. In QFT, an electron is an excitation in matter field.

comment Do particles keep on emitting energy?
And, that's the answer... Simply, drop the classical physics and move on.

comment Do particles keep on emitting energy?
I said so coz you can simply use uniform speed (rest is also uniform speed). BTW, See this: mathpages.com/home/kmath528/kmath528.htm It addresses your issue.

Opposite of acceleration isn't rest...
