Yes I've read this page, but I was wondering what the actual harmonic resonance equations sort of looked like so I got a better understanding of how it works!

I believe it had something to do with resonance

Has anybody heard of this odd sub-type of physics and geology? Apparently Tesla was able to build devices that could create earthquakes with his technology. I want to know what these sorts of equations looked like if anybody knew.

How can it be negative pressure though? That's what I don't understand.

So basically what you're saying is \begin{equation*} \begin{split} \Delta E &= \rho \Delta V &= - p \Delta V. \end{split} \end{equation*} If I'm correct, doesn't \rho = E/v? Or is this wrong to say?

okay, why do quantum fluctuations have negative pressure? What forces them to have this characteristic, and why is it different? Okay sorry george jones, but I didn't understand any of that. My mathematics are extremely subpar to my level of understanding for the logical part of it, if that...

I'm sorry but I understood basically every other word you said. according to how much I do understand, you say that quantum fluctuations create stress energy, wouldn't this energy actually cause matter to contract towards one another? (because of the whole gravity thing..)

So basically what you guys are saying is that this "dark energy" is actually the expansion of spacetime as a biproduct of quantum fluxuations? Does this mean that the amount of dark energy is uniform across all of space? And if it is just the stretching of spacetime, then how is it that we can...

does that mean the repelling force of dark energy is equal to that of the force of gravity?

Okay so dark energy repels mass, but why is that? The reason why masses repel other masses when brought together is the electromagnetic force, but dark energy also doesn't interact at all with electromagnetic waves, and if it exhibited electromagnetic force it would interact with electromagnetic...

okat but from my understanding, acceleration and "potential" to do anything is a product of mass. These things come from mass, not the other way around, or am I wrong?

so basically all energy comes from the forces? And with that all mass comes from the forces?

I've asked all of my teachers where mass comes from, like what causes things to be "massive" and all that. I know something has mass when it has energy blah blah blah but like, why do things have energy then?

I understand they're supposed to be analogies, but again you're taking a seemingly 2 dimensional plane (the trampoline) and putting 3 dimensional objects on it to make the plane bend into a 3rd dimension. But in the seemingly 3 dimensional plane that we live in and observe, how does a 3...

okay i understand a bit better now. This is a little bit off topic but for spacetime, all of the models that I see or read about have a 2-dimensional plane being bent by a 3 dimensional object. How can this happen when we live in a 3 (as far as we know it) spatial dimensional world with 3...
