TL;DR Summary
I understand from Noether's theorem, energy is not conserved in big scale space-time (because space-time is not static in big scales).
Also, I have heard from physicists that vacuum energy fluctuation (creation and destruction of virtual particles) violates energy conservation. The reason, they justify, is based on uncertainty principle (energy-time form of uncertainty principle), energy can exist and disappear for a very short period of time.
Could somebody explain this in simple words please?

This is not an acceptable referende. How are we to track that down and figure out where the misunderstanding is.

They do not.

Thanks Vanadium 50
How about vacuum fluctuation, does it violate energy conservation?

As has already been pointed out, this is not a valid reference. Without a valid reference we have no basis for a discussion.

For that reason, I am closing this thread. @Ebi Rogha, if you have a reference, please PM me and I will look at it, and if it looks OK, I will reopen the thread so you can post it.
 
I am not sure if this falls under classical physics or quantum physics or somewhere else (so feel free to put it in the right section), but is there any micro state of the universe one can think of which if evolved under the current laws of nature, inevitably results in outcomes such as a table levitating? That example is just a random one I decided to choose but I'm really asking about any event that would seem like a "miracle" to the ordinary person (i.e. any event that doesn't seem to...
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...
