Ha!, yes, what does it mean to understand something? To fully understand an apple you must fully understand the entire evolution of the universe, where it came from and down the rabbit hole we go :)
Still, chasing understanding is useful as every now and then something jumps out of the rabbit hole and changes things... Trying to understand the revolutions of the celestial spheres, why black bodies don't emit endless amounts of energy or what it would be like to travel at the speed of light.
