Formaldehyde Polymers in Cometsfor comets, (H.CO). is difficult to detect, even if it is present in relatively high concentrations. The optical properties of these polymers in the visual and infrared regions are similar to those of silicate grains, and crystalline formaldehyde polymers provide no emission at 6 cm wavelength. The

We think this popular view is wrong, for it is not the existence of the building blocks of life that is

It is a corollary that biology is the means by which an approximation to thermodynamic equilibrium is maintained in materials at temperatures ~ 300 K.
