We will have to study gravity and light in a new way, a new physics, if we are to attain the efficiencies required for that journey.
This tenet warns that no species should be destroyed or become extinct by our behaviour on any habitable planet, because a necessary clue to our survival may be hidden in that species.
The term "species" certainly includes all "groups" (white, black, red, yellow, brown, male, female, etc.) within the human species.
