Einstein's theories are pure nonsense. They depend upon the constancy of
the speed of light, which is wrong. Light speed actually varies with the
speed of the emitter. Then the optical effect of refraction was abused
to make it appear that the Sun bent the light from the stars. His
theories led to the concept of a finite but expanding universe. Now
Hubble and Webb telescopes show an infinite universe, with distant
galaxies NOT moving away at high speeds but going in all directions.

He demonstrates some coilguns he put together with off-the-shelf parts.

Coilguns are not railguns. Totally different technologies.
Arindam invented a new type of railgun with parallel rails spread wide apart, heavy armature and low voltage requirement with low reistance for high currents.
That design has been stolen by the US Navy and employed in its most modern ships.

Yeah it was sort of figured that they wear out too quickly,
because the armature vaporizes, while coilguns are pretty
much contact-less, so that the mass drivers or coilguns
have a longer mean-time-between-replacement.
These days there's been a lot more research in theory of
electromagnetic-gun-launch-to-space, what with that
the "space elevator" sort of disagreed with Coriolis.
Traditional techniques included the consideration of
just a plain old gunpowder-cannon, straight to space.
The idea of electromagnetic-gun-launch-to-space
has various economies of scale and re-usability.
Lasers, though, lasers is what's up these days.
