What is the approximate mass density implied by a teaspoon measurement of neutron star material?

Answer

Billions of tons.

The extreme density achieved during the collapse of a massive stellar core leads to material unlike anything experienced in normal astrophysical contexts. When matter is compressed to form a neutron star, it reaches densities where a very small volume weighs an immense amount. Specifically, the text indicates that just a single teaspoon of this ultra-compressed neutron star material would weigh billions of tons, reflecting the compression of matter to incredible levels.
