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 absorption of ultraviolet radiation by ozone depends on wavelength; this absorption protects us from ultraviolet light from the sun.



Which unanswered question in physics is more important?

What is dark matter?
What happened at the Big Bang? (and before?)
