As research into planetary habitability continues, through theory as well as observations, we will indeed continue to observe how
even basic physical principles can manifest in very different ways on these alien worlds.
When challenged to explain how he knows that, he says they start
with basic physical principles plus observations about the climate, which they then feed into models, pick and choose some of the outputs, then feed those into economic models, and voila.
Using these ingredients, plus
some basic physical principles, Einstein came to mind - boggling yet unavoidable conclusions that overturned all of physics.
Unable to pierce the black veil, astronomers have had to content themselves with constructing, from
basic physical principles, their own scenario for how a star takes shape.
Jim, here's the kind of interaction that makes it impossible to calculate this as a simple number, from
basic physical principles, for a complicated planet:
A basic physical principle of thermodynamics.
