If you were to hold that empty teaspoon just one yard above the star's surface and drop it, it would strike the surface at 4.3 million mph. :Q

100 million tons. That seems impossible. Only so many molecules could be contained in a spoon, if you pack them in with no spaces I don't see how it could way that much. I dunno.

black hole.


black holes from what we know is just compressed matter

Atoms are mostly empty space. Just as crazy a thought.

So imagine instead of that empty space, pack it with neutrons.

I'm going to guess...neutron star......



Yay! :)

And of course, your atoms never really touch anything you get close to. Like two magnets repelling one another, it's just electric repulsion keeping your atoms from getting very close.


But yes, the vast majority of matter is just empty space.

Nod. I normally hate analogies which make science relatable for the masses but one that really raised my eyebrows was that if a neutron / proton were the size of a marble, the electron(s) in its atom's orbit would be cross-sections of human hair 20+ miles away.

Would the tea spoon weigh 100 million tons over the neutron star or on earth. Are they stating mass or weight.

This source shows a calculation of the acceleration due to gravity on a neutron star being 1.86 trillion m/sec^2 and giving the same 4.3 million miles per hour figure for a 1 meter drop.

Neutron stars create such a strong gravitational field that the ONLY thing that produces a stronger field is a black hole, which is so strong it rips matter apart. It isn't surprising to think that a neutron star could pack matter in a density that we can't even conceive of.

Something never stood right with the concept of blackholes to me. Obviously, the matter cannot disintegrate to nothingness. This may mean that a blackhole can only get larger, eventually consuming the entire universe. However, it has been shown that every galaxy has a blackhole at its center, just like every rapidly circular movement has a vortex in the center. Hence, it must be turned to pure energy and released on the otherside.

Uh, you should read about them. I think you'd be interested. Matter doesn't just go into nothingness. It's all there, slowly falling into the black hole from a distant viewer, and already torn into subatomic particles in the reference frame of the fallen objects. Black holes supposedly emit radiation, too. This hawking radiation is what keeps microblackholes from growing.

The crust is basically a solid shell of neutrons, right? Neutron stars were always my favorite Astronomy Thing. Black holes are pretty easy to understand/explain, but Neutron stars are just plain weird.
