What is the densest thing in the universe?

Question

anyone know?

Answer 1

The center of black holes where the singularity is located is the densest thing in the universe. Second would be the center of a neutron star.

Answer 2

I'm tempted to snark and say "young-earth creationists" but that would be wrong.

I'd say by definition a black hole is the densest thing, since there is no way to put more mass into the same radius. But that might not be satisfying because it's not really a thing anymore.

Next up would be neutronium, the stuff neutron stars are made of. This is just neutrons jammed together, so it's as dense as anything made of normal particles could be.

Perhaps a bound collecton of more exotic baryons (with top or bottom quarks, etc.) would be denser but it probably wouldn't be stable long enough to tell.

Answer 3

Since mass and energy are equivalent, and the state of matter inside of the Near Singularity of the core of a black hole is unknown in actuality, I would go out on a limb and say that the densest form of matter would be the residual strands of matter converted during the Big Bang from High Energies before the cooling of the universe to just a smidgen less than 1 billion degrees Kelvin....... That mass would be roughly equivalent to the mass inside of an atomic nucleus..... a teaspoon of water at that density would weigh millions of tons.

Answer 4

The black hole is the densest thing in the universe. If the big crunch happens, that will be the densest thing since it will be the whole universe collapsing onto itself.

Answer 5

Neutron stars would probably be the densest material in the universe

Answer 6

The singularity of a black hole, under the current definition, is the densest thing in the universe.

By definition and mathematical solution, a singulary has infinite density. Good luck imagining that one.

A problem with the singularity is, in order to have infinite density it must be infinitely small.


Think about that for a minute. Infinitely small? Yea, that's right...it's a paradox. Something infinitely small has no size; it doesn't exist ;)

Answer 7

The densest object in the universe is a black hole in the centre of a quasar, as bright as 420 trillion suns. The black hole is approximately 12 billion solar masses!

Answer 8

Neutrons have a density of 1900 million tonnes/cubic centimetre, so this is the density of a neutron star. But the gratitational field of a neutron star is much stronger than the Earth's; at least 100 000 million times stronger, so a teaspoon of matter from a neutron star's crust would weigh more than the Earth. It's possible to compress matter to super-nuclear densities before it collapses into a black hole. Matter deep inside a neutron star has a density greater than that of neutrons.

Answer 9

Not neutron stars, black hole is the densest thing that ever exixts..even light cant escape it and i heard it probably spins time back too or holds time still.

Answer 10

To our knowlege, a singularity, if they exist.

Dense enough to tear a hole in the fabric of Space/Time.

And while the President's density may be enough to severly warp the universe around him, light does occasionaly still escape, so I'm giving Singularity the win.

Assuming singularity's exist, there's some question about that.
