That would mean that neutron stars (all the atoms crushed so tightly
together that individual subatomic particles lose their identity)
couldn’t exist either. But they do.
Radio pulsars exist.
The theory is that they are neutron stars. But theory can be wrong.
so we know the theory is wrong.
“A pulsar (from pulsating radio source)[1][2] is a highly magnetized
rotating neutron star that emits beams of electromagnetic radiation out of
its magnetic poles.[3] This radiation can be observed only when a beam of
emission is pointing toward Earth (similar to the way a lighthouse can be
seen only when the light is pointed in the direction of an observer), and
is responsible for the pulsed appearance of emission. “
This sounds like an electric motor, and if you think a galactic
civilization would not turn such into a gas station, I have news for you.
You can take advantage of the huge gravity to feed it oil barrel
projectiles full of liquid hydrogen to feed off of the explosions for more
power generation and keep the generator alive. The resulting spectrum would
be artificial, but we lack the theory to understand that.
A Dyson sphere compared to a pulsar looks like a comparison of a desk fan
to a modern wind mill.
