No, it was a contest. I thought I told you guys that. =P Oh well.Oh by the way, Quantum Tunnelling is a proven thing, apparently. I thought quantum mechs were entirely theoretical. We actually use Quantum Tunnelling for a special kind of microscope. (Quantum Tunnelling is a phenomena in which particles move through barriers that they couldn't with only Classical Mechanics.


Well they probably move through the atoms. Electrons are small, you know. I really don't have a problem with anything possible.

I already know you don't dismiss all of Quantum Mechanics. Just the stupid impossible stuff. Also, atoms can't move through other atoms. The electromagnetic field generated by the electron cloud repels other fields generated by other atoms, so no two atoms can take up the same space at the same time. So a barrier with atoms tightly locked together would be impossible for another atom to pass, since atoms are actually way bigger (relative to the nucleus) than you would think. I conveniently learned about the electron cloud a few days ago in my science book xD

I said electrons. No need to lecture me about it.
It still needs a way of actually getting to that location.

I'm not lecturing you...? Unless I am which is something I sometimes inadvertently do.

And we haven't proved exactly how it happens, just that it does. It's most likely because of quantum uncertainty in tandem with wave-particle duality, the latter of which I've been reading about in order to understand more clearly.

Until they can clearly draw and define the line of travel that the atom does, or could take, I won't accept that it spontaneously jumps through physical objects. Unless it becomes totally energy oriented and travels through other atoms, which for all we know, could be possible.

Apparently they did.



They can use that energy change to determine the path. And how can you not accept that atoms can spontaneously jump through objects when we've observed it happen and actually use a microscope that utilises that phenomena? It has a practical application in science, and we've proved that it happens. And also, uncertainty shows that the path will be... Uncertain. XD Although we can figure it out once it happens, I suppose.

Tell me, how does it go through it?
I can't accept physically impossible things. Science is just the art of proving yourself wrong, so I'll stick with beliefs that don't go against basic physical laws. For example, an atom can't be in two places at once.

It just tunnels right through. The analogy is this: Imagine a ball rolling over a hill. Classically, if it doesn't have enough energy, it'll roll back down. Classically, if an atom didn't have enough energy to penetrate a barrier, it would bounce back or be absorbed. However, there's a small probability that it'll actually tunnel through even without the energy required to break through. This is because of quantum uncertainty and the principle that matter has properties of both waves and particles. Uncertainty states than it is impossible to know both the momentum and position of a particle exactly at a given moment. There is a limit to our preciseness when involving both.

Doing the maths shows us that the probability that the particle is on the other side of a barrier at the needed moment is not zero. Hence, there is a small chance that the particle will appear on the other side of the barrier, with a wave frequency proportional to the probability that it would happen (different with circumstances, of course, but always nonzero within 1-3 nanometers). That is how quantum tunnelling, an actual proven thing that happens and we use, works.

The biggest problem I have is the "we only have so much information, cannot get more at a specific moment, which means that this is certain."
Like Schrödinger's Box, I don't have a problem that something works, but I have a problem with the way we try to explain it, and that we can't accept a simple "I don't know yet." The atom must somehow convert to energy, or do something physically possible, because nothing can change location without traveling.

Well, it does travel. Wave-particle duality, remember? It moves like a wave in order to get through. The frequency of the wave changes proportional to the probability, in such a way that the particle is able to tunnel right through. It practically appears, although it's moving in a wavey way. It's not turning into electricity, and it is doing something physically possible.

I didn't say it was turning into electricity. Regardless, I don't believe that God changes the rules for small things, so take you theoretical physics, and I'll stick with my theories and rules. I'm sure it gets there, but I doubt it breaks physical laws to do so.

Each to their own. Maybe one day we'll actually see how it happens, other than just knowing it does XD But for now, that's the best we can come up with.

I'm not saying that I think it's the best show ever, I just got hooked on it. I also got attachted to a character who was killed and was repeatedly brought back up by her father, when they had to let her body go in order to survive, and yeah. Petra Ral is the char's name.

Dude, I watched the whole thing. Petra was my favorite.
