Some “skeptics” say it can’t be done. They are denying basic science! Gravity is plainly true. So is the heliocentric model. Everyone agrees. There is an overwhelming consensus. So the time for discussion is over. There is no doubt about the Mars mission.
I create this analogy (note 1) for people who don’t understand the relationship between five completely different ideas:
- the “greenhouse” effect
- burning fossil fuels adds CO2 to the atmosphere, increasing the “greehouse” effect
- climate models
- crop models
- economic models
The first two items on the list are fundamental physics and chemistry, and while advanced to prove (see The “Greenhouse” Effect Explained in Simple Terms for the first one) to people…
