What sort of engineering would be required to create a teaspoon of neutron star matter? The sort that we will never be able to achieve. Anti-matter is far more destructive, by the way, but we cannot create more than a few subatomic particles of it at a time, and there is no known way to store it without it exploding.
Assuming that we can develop the technology at all, we wouldn’t be doing it in teaspoons, but in amounts that would let us generate energy.
“”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.
One teaspoon of neutron star matter would be impossible to contain. It would be so dense it would sink down and through the Earth. Unstoppable.
