Question

what is least dense thing on earth​

Answer 1

Answer:

For a long time, aerogel was the lightest and least dense material ever made. Late last year, a metallic lattice structure took the crown. And today, the new champion is officially aerographite, with a density so low that it barely exists at all. The density of aerographite is a mere 0.2 milligram per cubic centimeter.
