Dense material
what is the most dense man made material? Just kind of curious

I would imagine Osmium.
It's not really "man made" however.

I dunno about man-made, Iridium is the densest natural one though.
It seems man keeps outdoing itself.

Assuming 40 times harder also means 40 times denser.

Here I was assuming that hardness and denseness would be the same thing! :eek:
Was I in error? Squeezing molecules together as tightly as possible is what we are talking about right? :(

Would it be terrible of me to suggest perhaps, Corneliu?

You can make your own by simply bombarding gold ions together.

Ace!
Now to steal my girlfriend's jewellery to try this...

If we're talking about materials that are stable at room temperature and pressure, then it's the heavy metal osmium. It's "man-made" in the sense it has to be purified. You can't go much denser from this, because density is determined by the electronic structure of the atoms of the metal. You can't customize the electronic orbitals - they're naturally what they are, and can't be changed.
But if we're talking about unstable materials, then there are at least these:
the "simulated sun" experiment where bullets are shot at each other to recreate the conditions in the sun
fusion reactor fuel compressed with laser beams from 91 meter-long lasers
heavier transuranium elements.
None of these persist for more than a split second.
In particle accelerators, even more dense states of matter can be produced. These involve only a few atoms, so it's questionable if it's "material" at all.

...ice floats on water, therefore ice is less dense than water... ergo, water is harder than ice?

Wll my whiskey is. When I drop the ice in, it cracks.

Republicans.

Republicans.
Is man man-made? Is man a material? Are Republicans man?
(notice how "man" is a mass noun here, singular: one piece of man, plural: man)

Republicans are made in a factory in Des Moines.
Not sure where you're goin' with that otherwise.

NO! I REFUSE TO ACCEPT THAT!
Everyone knows that Mr. T's gold chain is 1000 times denser than Chuck Norris.

If you made a bullet out of Chuck Norris and Mr. T's gold chain it would chew through Superman rather easy. The problem is finding a gun that could actually fire it.
hmmm, I think you will be hard pressed to find the hardest man made substance as the stuff that we make that is dense (diamonds) has a natural variant, and the stuff we make that doesn't have a natural variant is not particularly dense (plastics, ceramics, textiles).
As far as the densest natural substance, you would have to go with the material a black hole is made of.

Technically, with zero volume, a black hole's density is undefined.

Actually its not 0 volume as the event horizon has a definite diameter, and there is a minimum amount of mass needed for gravity to overcome the repulsion force of the atoms. Thus you have total area and total mass, with a defined density, although density will vary (am I wrong?). Anyhow, second place would be the material of a neutron star, a gram of neutron star would crash through the floor and head straight for earth's core.

Eh, I was thinking singularity...whatever. anyways, Iridium barely edges past Osmium

After reading your stigmata post I would have to say your brain. ;)
Depleted uranium is super dense. Though anything higher is harder to produce on a large scale.
