Researchers have created a new metallic material that they claim is the world’s lightest solid material. With a density of just 0.9 mg/cm3 the material is around 100 times lighter than Styrofoam and lighter than the "multiwalled carbon nanotube (MCNT) aerogel" - also dubbed "frozen smoke" – with a density of 4 mg/cm3 that we looked at earlier this year. Despite being 99.99 percent open volume, the new material boasts impressive strength and energy absorption, making it potentially useful for a range of applications.
