Summary of El Sólido Más Liviano del Mundo - AEROGEL

Aerogel is the lightest and least dense solid in the world, with a mass of only 1.22 grams and being 99.8% air.

Aerogel was invented in 1931 by Samuel Kistler by replacing liquids in gelatin with supercritical fluids to create a solid nanoporous structure.

Aerogel is a highly effective thermal insulator due to the Canut Sanz effect, where the narrow pores block heat transfer.

NASA uses Aerogel insulation in various missions, including Mars rovers, and for trapping dust particles from comets.

Aerogel is transparent, scatters blue light, and is being researched for potential everyday use in thermal insulation.

Scientists are working to reduce costs and increase durability of Aerogel, with efforts to make it waterproof.
