There is a non-zero probability (quantum mechanics)

i, on the other paw, find it quite comforting, that diversity, which is the real source of all hope, is the nature of existence, and that unlike a living person, it is cheerfully immune to intimidation, by anything what so ever at all.

 

Yes, I suppose troubling is the wrong word. But no random event can possibly be any more or less random than any other, so why not go through the walls every time?

I certainly don't think of the universe as non-living. One of my favorite things to do is love it and hope it understands.

 

Lol science. Trying to make be believe things they're not even sure of.

 

Intriguing idea you've posed. I'd like to take a "crack" at it..
Matter and energy are best related firstly via Lavoisier's "conservation of matter" theory: matter is never created or destroyed, merely changed in form. Add in Einstein's E=mc^2 and you find that matter and energy are interchangeable if matter is accelerated (or given enough energy) to the speed of light. In quantum mechanical terms, the universe is like a sea of "quantum" energy. An electron is like a ripple that's in any of a number of places at once, until the ripple "coalesces" or collapses into a "point" particle. And photons (the messenger particle for magnetism) are like a compressed wave front that acts like a particle as the electron moves. Stationary electron, no photons.
Heizenburg's uncertainty principle states that we can never know the exact position of such an object. Also, DeBroglie developed the description of any primary (fermionic) subatomic particle as a "wave function". I've postulated that our universe's "energy essence" is like a gigantic wave function (like a carrier wave in radio) and if another universe with a similar "wave function" superimposes on ours, the result is like feed-back in a microphone-speaker analogy; except instead of deafening noise, the result is formation of fermionic matter.
Now as to anyone "jumping at a wall" and disappearing. If we factor in the Planck unit to DeBroglie's wave function and temper it with Heizenburg's uncertainty variable, we find that ALL matter no matter how much "vibrates" and has an uncertainty factor. Except that for anything larger than an electron, or even a proton, the "vibration" and subsequent "probability" of your matter decohering into a wave is very, very small. Of that you'd need ALOT of energy. And at that point, if you could get THAT much energy focused on you, "all the king's horses and all the king's men won't be puttin you back together again!"

 

think about it, if we ( or any other "normal" matter {normal as opposed to dark matter}) were able to go through a wall AD LIB!
How easy would it be for the ground under you or the atmosphere, or a whole mountain range to "suddenly" dematerialize! And then let's say, for thought experiment sake, a passenger jet or hundreds of cars were "passing through" at any point in time, and the aforementioned mountain dematerialized just before they got to it...only to rematerialize as they're passin through...YIKES!!!
Now as to a "living" universe, be careful; to think in terms of it as a dynamic continuum that's of a magnitude and variability beyond our comprehension? Sure. But living in the sense of a growth, reproductive and maturation cycle with an expressed intelligence? I'm not arguing, but have fun substantiating it..
