“”What sort of engineering would be required to create a teaspoon of neutron star matter?””
I remember one of my 10ยข Superman comic books. In order to save the world/galaxy/universe one more time, Superman flew to the surface of a neutron star and scooped up a handful of it.
I had to look this up, but the surface gravity of a neutron star is about a trillion times the earth’s. That would be some feat. One might even say, Super.
