I suppose that on the Earth this element is platinum with a density of 21,45 g/cm3.
the most dense material that is known Sound cannot pass through a vacuum.
The questioner.
it is the most dense thing because it is a squash peice of matter
There are a number of things that may happen to substances that are less dense than the surrounding material. In most cases, this is what will cause them to float on the surrounding material.
Earth is the most dense, Mercury is second, Venus is third, and Mars is the least dense.

The most dense material in the universe is stellar ash - the remains of a star that has come to the end of it's life. A teaspoonful of stellar ash would weigh on earth thousands - to millions - of tons.
Nucleolus (:
No,it is certainly not, although it is one of the main contenders for "most dense substance on earth".
One made of dense but highly-elastic material.
Gases, by definition, are the least dense state of matter. The material that is most dense will sink to the bottom. The material that is least dense will rise to the top. Gases are least dense so they will rise not sink.
At the heart of a black hole, a cubic inch of material would weigh an infinite amount.
