On earth, as we convert mass to energy, the earth loses mass, correct? And
if so, are we not reducing the earth's gravity, if even just a bit?

BV.


IMHO, Maybe a bit, but an immeasurable bit! Local temporary decreases in
entropy, e.g. life and it's fiddling about on the skin of this planet,
are less than trivial compared to the net gain in mass from hoovering up
particles from space.
I think I read somewhere that Earth picks up around 600 tons from space
each year, (seems low to me), so that's roughly, assuming a constant
rate for the sake of simplicity, 6*10E10 tons since the solar system
began to settle down. If we'd converted even a tiny fraction of that
kind of mass to energy, we wouldn't be here :-)
