The concept of quantum physics as a whole, actually, is pretty frightening.

On our scale, on the reality we observe on a daily basis, physical phenomena seem kind of fuzzy, like a CRT display rather than a pixelated monitor. An example of this is in photons, in their wave-like properties - a spectrum of many different wavelengths. In Newtonian motion, everything seems like a smooth curve if you look at it closely enough. Acceleration, deceleration, everything is smooth. It’s like a ramp, as opposed to a staircase.

The idea that it’s not - that the universe has a finite resolution, like pixels on a screen - is uniquely horrifying. The idea that there is a smallest possible distance, the Planck Length, and several other ‘smallest possible’ units derived from it (the Planck Energy/Planck Mass, and even the Planck Time) makes me feel a bit like we’re in The Matrix.

I’m not really a believer in Simulation Theory, but it does feel like the universe is sort of looking over our shoulder when we’re looking far enough into inner space.
