Hubble and Webb telescopes show an infinite universe, with distant
galaxies NOT moving away at high speeds but going in all directions.
I'm sort of a fan of this guy: https://www.deltaveng.com/ .
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.
Wrong on oh so many counts.After 15 years and $500 million in research, the US Navy gave up on
railguns in 2021.Railguns were never deployed on Navy ships other than for testing.
The photo of their new barrel based on Arindam's new design is on Arindam's Facebook timeline. On 10 March. It shows clearly twin barrels and mentions 500 million dollars. Trials are going on.
