The myth that bumblebees shouldn’t be able to fly according to science needs to die.

They wouldn’t be able to fly in an outdated, simplified model, where you pretend they’re birds and just plug in their wingspan and weight.

If you account for the fact that air molecules are a lot larger relative to their size than to a birds, so air acts more like water at that small scale, and they don’t just move their wings up and down but in a complicated movement that shapes the turbulence, it’s no surprise they can fly, and scientists know that.
