# Neutron star material

I've read on NASA's page on neutron star that one teaspoonful of that star would weigh over 20 billion ton on Earth. If it was somehow possible to bring it to earth would it: A) Burn and disappear during earth atmosphere entry? B) Assuming we bave 20 billion ton of mass in size of a teaspoon here on earth, would it fall through the ground under its own weight?

just want to highlight that we don't know this for sure: its possible that after reaching nuclear densities, matter is essentially stable entirely due to nuclear strong force. It is believed that islands of nuclear stability become more strong as $Z$ and $N$ grow above 150. However finding such super-dense pieces of matter will be almost impossible in the surface of the earth, since this will likely sink inmediately until reaching the center of the earth –  lurscher May 19 '11 at 5:50
