I believe there is a fatal error in this picture

As I understand it, in this picture both the time axis and the radius axis are logarithmic, yet both t=0 and r=0 appears in it. The artist seems to have been completely ignorant of the fact that log(0) = - ∞. The origin of time (t=0) thus cannot fit into any frame of this picture. Furthermore the radius seems to range from -r to +r. The value of log(-r) we can only "imagine". I fully appreciate the difficulties that meets anyone trying to capture complex cosmical concepts in a simple two-dimensional picture, but maybe there still should be some limits to what amount of licencia poetica we should accept.

Nuclear Fusion?

It is my understanding from various sources on the net including Wikipedia itself that nuclear fusion took place from 3min to 20 minutes after the big bang. The image has nuclear fusion starting and ending before 3 mins. — Preceding unsigned comment added by 50.0.12.23 (talk) 16:43, 27 September 2015 (UTC)[reply]
