Can we use BECs or even something similar but different like superfulid helium 4 in a sigle quantum state to observe phenomena and interactions on the subatomic scale?
A curious non stem midwit, i was surprised to learn the the commonly taught idea of things existing in superpositions or as smears of probability is likely not an accurate description of reality and read that BECs can make quantum interactions visible on a more macro scale.

Are there any other ideas that fit the math but may more closely describe reality? So much seems to be guesswork.
