The inference being that energy and mass are reversible such that mass can be converted into energy (as in a nuclear bomb), but energy can also be converted into mass, as in creation.

Something to think about.
Feynmann said, if not for the unfortunate choice of the second as the unit of time, that the equation is just:

e = m
Energy equals mass.
Though Feynman was a brilliant physicist and a Nobel laureate and I am neither:
kinetic energy is mass times velocity squared. So you can't leave out the velocity in the equation otherwise you compare apples to oranges.
Of course in our Mass there is also some chemical energy, but this depends on the type of matter....so our big bellies help, but carrying around a big lump of quartz won't.
@moonbussaid You can turn them on all right, but they won’t illuminate anything ahead of you that you haven’t already overtaken anyway.
You are in the black void of deep space going backwards in your car of the imagination at the speed of light and being followed by another car 100 feet away travelling at the same speed. You turn your headlights on; would you see the other car?

No. And it would not matter if the void were full of light and you did or did not turn on your headlights. You would not see it. Nothing, no photon or other form of information, from the car 100 feet away could catch up to you and impact on your sense organs. Neither could you receive a radio message transmitted from the other car.
There is an elementary Denkfehler in thinking that by turning on your headlights you see anything. You do not. What you see at terrestrial-speeds is not your headlight beams going out--what you see is your headlight beams reflected back to you from some object (fog or another car or a frightened deer in your path or whatever). It should be evident that two vehicles travelling in the same direction at c cannot send and receive back a reflection from the other vehicle travelling at the same speed.
