TitleLetter from Thomas Gold to Professor Victor Weiszkopf, Department of Physics, Massachusetts Institute of Technology, Cambridge, Massachusetts
Date17 April 1978
DescriptionEncloses a few pages from a proposal Gold submitted to the NSF that explain some of the oxygen balance situaation in the last 10 percent of geologic time, when photosynthesis is really widespread.

The table Gold showed in his talk was concerned with the problem of how to maintain a low oxygen level in the earlier nine tenths of the time, despite the oxidizing tendency of the escape of hydrogen, and for that a large amount of methane addition to the atmosphere is also required.

States this will set Weiszkopf's mind at rest that his statements in the book are correct, and photosynthesis will really add to atmospheric oxygen in the case that more CO2 is supplied than deposited. But of course this is not the only possibiity, especially since the entire oxygen excess on the surface or near it is probably due to the earlier long period of hydrogen escape, and the source of the oxygen to make CO2 may be largely due to this.
