Oh you haven't even scratched the surface of disbelief about pulsars and neutron stars.
These are bodies that didn't quite make black hole status. They are only supported by quantum mechanics otherwise they'd collapse as black holes.
A teaspoonfull of neutron star material would "weigh" as much as 100 million elephants.
They have magnetic fields a trillion times (1,000,000,000,000) that of the Earth.
Everything about these exotic beasts boggles the imagination
