Think of the universe as a painting. There’s the image made in paint, and the surface it was painted on. The canvas.
The stars, the planets, the gasses, the matter and energy and even the space between are the paint. What’s the canvas? Is there a canvas? Would the canvas follow the same rules as the paint?
How do quantum physics play with spacetime?
I’m probably not asking the right question for what I mean… For context into my own thoughts process here, I originally thought of the question when reading a science post on quantum physics vs general relativity and how they don’t mesh and wondered “could we be seeing the medium simply behaving differently than the art?”
My understanding is that quantum physics is the study of the incredibly small, and general and special relativity are the study of everything else. They don’t overlap (rules for big don’t work for small, and vice versa) and are two separate understandings. Which is why the, hopefully, next big thing will be a unifying theory that applies to everything. I believe Stephen Hawking was a well known scientist working on finding a universal theory.
Which doesn’t really answer your question, but it’s a question far surpassing my knowledge. I think quantum mechanics just doesn’t interact with spacetime, or at least not in a meaningful way (mass of an electron is so incredibly small it isn’t perceptively effected by spacetime curves).
I would be happy for someone with more knowledge to come and prove me wrong though, these are fascinating fields.
