Aerogel is not like conventional foams, but is a special porous material with extreme microporosity on a micron scale. It is composed of individual features only a few nanometers in size. These are linked in a highly porous dendritic-like structure.
This exotic substance has many unusual properties, such as low thermal conductivity, refractive index and sound speed - in addition to its exceptional ability to capture fast moving dust.

Aerogel (also called 'frozen smoke' because of its hazy blue appearance), is a truly remarkable material.
It is the lightest and lowest-density solid known to exist, and holds an unbelievable 15 entries in the Guinness Book of World Records, including best insulator and lowest density solid.
Aerogel is composed of 99.8% air and is chemically similar to ordinary glass.
Being the world's lightest known solid, it weighs only three times that of air.

Imagine these things coating "invisible" orbs.....
I still believe ALL Ufo's are man made.
