Unbearable Lightness - A new metallic lattice structure named aerographite has dethroned aerogel as the lightest material known to man. The new material will have many crucial applications in aerospace systems, especially as thermal insulation.
Despite the fragile look, aerographite has some impressive structural properties. You can compress it down to make it 1,000 times smaller, and it’ll spring right back to its original size when you let go. It can also support over 40,000 times its own weight, which is 35 times better than aerogel can do.
