These are the questions that make me feel such an insane sense of wonder and awe.
How deep does it go?
How high does it go the other way? How big does existence get?
Why is there something rather than nothing?
What is nothing made of?
Nothing is more of a definition than a thing. It's just the absence of matter.
Even in the absence of matter, there’s still the quantum foam. The most perfect vacuum is teeming with this energy. To truly understand the nature of 'nothing,' one would need to venture beyond spacetime itself—and even then, it’s not guaranteed that 'nothing' would be found. Physics suggests that anything existing outside of or predating spacetime would generally have no impact on us; it doesn't necessarily explain what the 'outside' might be like.
I'd say nothing is less a definition but rather an informal shorthand for how we percieve at macro scale with our wrinkly 4D brains.
And then even when you try to peer behind the definition of "nothing" with math all you are greeted with is infinities which we handily just swept under the rug and pretended to be zero so we could define a "nothing" state in the first place!
