      Bees flying and tides are both well understood now. Tides have been for hundreds of years.

      I don’t know enough aerodynamics to describe how bumblebees fly

      Tides are caused by the sun’s and moon’s gravity attracting the Earth’s land and water.

      If you had just said tides, I would have presumed you were being sarcastic, but bumblebee flight wasn’t explained until fairly recently (within the last 25 years or so)
