Maybe there are many levels of reality... quantum physics says that things exist only objectively when they interact with us, something completely isolated doesn´t exist in this interpretation, but maybe it could exist in some other level or form, not a objective, physical, or manifested existence but another. Thats just my opinion, quantum mechanics tells nothing about that.
But to answer your question about connectedness..through vibrations and frequencies....the way I've understood and read about it..is that with the discovery made by quantum physicists when breaking matter into smaller and smaller pieces you eventually reach a point where those pieces...the electron, protons...etc..no long posses any traits of the object....Physicists have found that it literally possesses no dimensions..If you try to measure the width of an electron you will discover that it is impossible...an electron simply is not an object as we know it..Also they've found that an electron can manifest as either a particle or wave..but not the only form..it can also dissolve into a blurry cloud of energy and behave as it were a Wave spread out over space...When it manifests into a wave it can do things no particle can do..If it is fired at a barrier in which two slits have been cut...it can go through both slits simultaneously...when in a wave like form..it creates interference patterns...Electrons are shape shifters..To shape shift is just another capacity of quantum's abilities..It's been realized that these particles have an interconnectedness...This new field is called quantum potential and theorized that like gravity, it pervades all of space, but unlike gravity fields, magnetic fields...etc...it's influence didn't diminish with distance...Science realized that this quantum potential acted as an organized whole.....and the the particles are not independent things, but parts of the indivisible whole system...and that it was more primary then reality....Physicists called this property "non locality."...So, everything is connected as a whole when you get down to the subatomic particles...you, me, the universe, your lamp, your table...our thoughts...There have been many experiments done in this area...and I find it fascinating that we all are connected to this SOMETHING...AND TO EACH OTHER....And this something has some kind of intelligence that inter reacts with each of us and we are that intelligence also. Everything has a vibration/frequency and other dimensions...alternate realities...particles also blink in and out of what our eyes can see...Where do they go?????...then they come right back.....sounds like dimensions.
Hope this helps though I'm not an expert...I copied this from what I've written else where.
Thats an interesting part of physics, I think that is "quantum entaglement" a property that particles have that when they interact at least once, they can share a conection to each other that exists even when they are separated, and distance doesn´t matter. Scientists think that at the time of the Big Bang all particles where at the same point and all of them interacted with each other, so thats possible that everything is connected to each other by that quantum entaglement in someway.
