  • “Why is it colder now than before?” It is November, and winter is approaching. Winter means colder weather.
  • “Why is the weather cold during the winter?” Earth’s rotation about itself is on a tilted axis relative to its orbit around the Sun. When Earth’s tilt is pointed away from the Sun, the Northern hemisphere gets less sunlight, creating winter. I sketch a picture:
  • “Why does Earth orbit the Sun?” There is (kind of) a force of gravity attracting all masses. That pushes Earth towards the Sun, but since Earth is already moving, Earth continually orbits.
  • “Why is gravity there?” The Sun, being a big mass, creates an imprint on spacetime that curves it, like a ball placed on a flat paper held at its edges. That curved spacetime geometry guides the Earth’s path around the Sun.
  • “Why do masses create a curved spacetime?”
Called Agrippa’s Trilemma, the figure illustrates the three possible outcomes of a series of ‘why’ questions. The infinite regress is explained in [1].
Pythia utters physical statements, which fallible correspond to abstract propositions. Only those propositions can correspond to reality or not.[11]
