![Aerogel
“Aerogel is a synthetic porous material derived from a gel, in which the liquid component of the gel has been replaced with a gas. The result is a solid with extremely low density[1] and thermal conductivity. It is nicknamed frozen smoke,[2] solid smoke, solid air or blue smoke owing to its translucent nature and the way lightscatters in the material”](http://25.media.tumblr.com/tumblr_m9d806Suff1r4dhkuo1_500.jpg)
"Now, a team of physicists says the Big Bang should be modeled as a phase change: the moment when an amorphous, formless universe analogous to liquid water cooled and suddenly crystallized to form four-dimensional space-time, analogous to ice."
