if a vacuum is really absoloutly nothing wouldn't that mean there is no edge of of the universe and so the universe is infinite.

The vacuum is NOT empty...it is a common mistake to think that. Besides, we even have experiments that prove, the vacuum is not empty...

scroll down until you come at the "string theory part 1"-entry and read to first two paragrafs. they will explain you why the vacuum is not empty...

enjoy

And whether or not a vacuum is nothing is irrelevant to whether or not the universe is infinite.

well, I think he was eluding to the idea that space is a vacuum and he sort of connected space and the universe together...
 

Thread 'Schrödinger equation and classical wave equation'

Not an expert in QM. AFAIK, Schrödinger's equation is quite different from the classical wave equation. The former is an equation for the dynamics of the state of a (quantum?) system, the latter is an equation for the dynamics of a (classical) degree of freedom. As a matter of fact, Schrödinger's equation is first order in time derivatives, while the classical wave equation is second order. But, AFAIK, Schrödinger's equation is a wave equation; only its interpretation makes it non-classical...

Thread 'How strong is the justification for low probability extreme thermal fluctuations?'

I asked a question related to a table levitating but I am going to try to be specific about my question after one of the forum mentors stated I should make my question more specific (although I'm still not sure why one couldn't have asked if a table levitating is possible according to physics). Specifically, I am interested in knowing how much justification we have for an extreme low probability thermal fluctuation that results in a "miraculous" event compared to, say, a dice roll. Does a...

Thread 'Quantum Entanglement is a Kinematic Fact, not a Dynamical Effect'

Insights auto threads is broken atm, so I'm manually creating these for new Insight articles. Towards the end of the first lecture for the Qiskit Global Summer School 2025, Foundations of Quantum Mechanics, Olivia Lanes (Global Lead, Content and Education IBM) stated...
