On the subject of our 'finely turned universe', I have read that the proton-electron mass ratio can not deviate more than 1:1037. In other readings, the allowable deviation was stated as 1% ("If the neutron were very slightly less massive, then it could not decay without energy input. If its mass were lower by 1%, then isolated protons would decay instead of neutrons, and very few atoms heavier than lithium could form."
Scientists using a Effelsberg 100-m radio telescope have determined that the ratio has changed "by only one hundred thousandth of a percent or less over the past 7 billion years"; alternatively, the change is written as 10^-7.
My question is: Is the change in the ratio (one hundred thousandth of a percent, 10^-7) greater or less than 1:1037?
[1:1037 is 1:10 to the 37th power]
