"The more I examine the universe and the details of its architecture, the more evidence I find that the universe in some sense must have known we were coming." - Freeman Dyson



Which physics relationship is more important?

How the absorption of infrared radiation by gases in Earth's atmosphere depends on wavelength; the resulting greenhouse effect provides us with temperatures that enable life to flourish.
How the gravitational force between two masses depends on their separation (shapes the universe).



Which unanswered question in physics is more important?

Must the properties of the universe enable us to evolve to observe it? (This idea is called the anthropic principle.)
Does the proton decay?
