Are black holes the densest thing in the universe?
Black holes are some of the strangest, most wondrous objects in all the Universe. With huge amounts of mass concentrated into an extremely small volume, they inevitably collapse down to singularities, surrounded by event horizons from which nothing can escape. These are the densest objects in the entire Universe.
What is the heaviest cheapest material?
The heaviest (most dense) is lead, depleted uranium not being much available. The cheapest is mild steel.
Where is osmium found?
Sources of osmium
Osmium is produced as a by-product of nickel refining. The element occurs in the mineral iridosule and in platinum-bearing river sands in the Urals, North America and South America. While there is little osmium in these products, it can be easily obtained from processed nickel ores.
What are some dense objects?
Examples of dense materials include iron, lead, or platinum. Examples of sparse materials include Styrofoam, glass, soft woods like bamboo, or light metals like aluminum.
Is diamond the most dense material?
Diamond has the highest number density (i.e., the number of atoms per unit volume) of all known substances and a remarkably high valence electron density (rws = 0.697 Å).

What is the densest object in our solar system?
Earth is closer to that limit than anything else in our Solar System, and the combination of its relatively dense composition and its enormous self-gravity, as we’re 18 times as massive as Mercury, places us alone as the densest object in our Solar System.
What’s the heaviest object in the universe?
So massive stars become neutron stars – the heaviest things in the universe – and even more massive stars become black holes.
Is water heavier than steel?
While steel is denser than water, air is a lot less dense than water (see Table 1). Metal ships can float because their total density – steel plus air – is less than that of the water that they float on.

Is sand heavier than rock?
Must be sand, because it has more moisture than rock. And the moisture would cause the sand to be heavier. On the other hand rock is solid, Depending on the kind of rock. Still, unlike sand there would be no air pockets in the gravel as there is in sand.
What is the strongest material?
Graphene has provoked excitement in the scientific community over the past several years.

How dense is tungsten?
5,900°C). With a density of 19.28 g/cm³, tungsten is also among the heaviest metals which is why it is used among other things for specific mass balancing.
Is osmium denser than water?

Bismuth is the next densest at 9.6 g/cc then lead at 11.34 g/cc.
Can a wormhole exist?
Einstein’s theory of general relativity mathematically predicts the existence of wormholes, but none have been discovered to date. A negative mass wormhole might be spotted by the way its gravity affects light that passes by.
