Layman here, so this is another infuriatingly wrong pop-science ispired question. :)
The way I understand it an electron (and many/all other elementary particles?) is not a little ball orbiting an atomic nucleus, but rather is rather smeared out in a cloud of probability. At any time it's somewhere inside this cloud, with some areas being more probable than others (say, the particular orbital that it's inhabiting at the moment). However, this cloud extends infinitely in all directions, so there's also a (very very small) chance that the electron might suddenly appear somewhere further away. And since the cloud is infinite, then... this includes the rest of the universe??? That doesn't seem right. At the very least there should be a limit of speed of light.
Which part have I gotten wrong?
