I got this from my grade 12 physics notes. It says that Earth, having a mass of 6.0x10^25kg and a speed of 3.0x10^4 m/s, when plugged into the wavelength equation λ=h/(mu) (where u is speed), has a wavelength of 4x10^-63 m. Then, does this mean it has a frequency of 7.5x10^70 Hz? If so, then it also means that the Earth's wave's energy is 4.97x10^37 J. My main confusion is that I always hear scientists say that quantum mechanics has practically no effect on the macroscopic world (except for some things like bucky balls and superconductors). I would think that a wave with the energy of 4.97x10^37 J would have to have an enormous effect on something or even the Earth in an interference pattern using the Sun and other planets as its own really large double slit experiment.
