Lawrence Krauss: "A Universe From Nothing" - YouTube
Since I watched this video months ago I've been trying to conceptualize how sub particles can exist one second and not the other, only to exist again. Can anyone? Also time bending. How can we process the things were learning about the natural world when the rules keep seeming to change? I know they aren't, were just discovering more but how do we process it in every day life? How do the physicists make sense of it?

Well i could not watch the whole video because my connection is too slow and limited, but i read what you are saying.
If the particle is there one second, and the same particle is not there then there a second or two later, then it must have been absorbed into another part of the universe, changed forms as energy does, then reclaimed it's own form. If you were to say to me that the same particle without changing is doing this, then i would guess you were coo coo. It must have changed forms and back again, now the same thing, yet found with a change in itself.

The rules keep chjanging because the universe is always changing. we evolve, animals evolve, stars evolve, asteroids evolve and this means everything else changes too.
If you were to take the universal way things work, they change as the things around them change. This comes from atomic reactions. As the universe grows by milimeters a second or whatever, the stress placed on all matter is changed, changing the laws of matter interaction. Then we could also say that rules here on earth have not changed yet. Maybe that is due to the ozone layer?

Virtual Particle
Einstein's Theory of Relativity predict that Space-Time are distorted/ curved/ bent by matter and energy. The more massive the object, the greater effect it has on distorting time and space.

What rules are changing?
What?
Even non Physicists can make sense of concepts in Physics.
So they are not the same particles? okay, that is easier to understand.

Or, of course, if the particle was to completely not exist, then the same particle was to exist, then not exist, then exist again, i would have to say that it was a bit of matter sucked into a black hole, then annihilated, then the black hole spits it out again in another form, yet the same pariticle.

If I remember right, it's an argument from symmetry. The average of zero is zero; but the average of 1 and -1 is also zero. Virtual particles exist only in opposing pairs, and conservation of energy need not be violated.

"Sir, I exist!"
"However," replied the universe,
"The fact has not created in me
A sense of obligation."

Yes things change but I'm not sure the rules do. I think we just don't know them all and we keep discovering more of them.

Thanks for the information but that wasn't what I had in mind. I was asking how we would use this information in daily life. Like in space missions or something.

Interesting. If you don't mind schooling an old man, how would the two virtual particles become a particle? Or am I comfusing what the video was saying?

Dropping one of the pair into a black hole will prevent its twin from dematerializing. The escaping survivors are called Hawking radiation.
This sounds like a way to get matter and energy from nothing, but it's not. Due to math I don't understand the black hole will become lighter every time a particle of Hawking radiation escapes. Nobody's ever seen a black hole up close either so everything about this is just what the mathematics and the lab-safe models say.
If you don't have a black hole to just play around with (you indigent human) you can also hit a virtual particle pair with an appropriate hammer. Adding more energy can separate them and make them both real.
The more you complain, the less I care about your problems.
I believe finder was looking for something that was, is not, but shall be... you propose it from the standpoint of not being then being, yes?
Actually, finder, is that what you meant?
