Why would previous versions of Python3 (e.g., 3.5, 3.6) not perform as well as 2.7? What about Python3 makes it slower? Is it a language design issue? We’re in the process of migra…

AFAIK, we are unable to see the center of the galaxy with visible-spectrum sensors due to the immense amount of dust and gas. We can see the center with IR sensors, however.
