Hi, Recently, I was thinking why electrons move so fast that we cannot even predict their exact position? I came up with an answer that electrons appear to move faster because their radius of revolution around the nucleus is very small compared to us. I was thinking if we could somehow shrink ourself to the size of an atom, then the distance between the nucleus and electron would be bigger compared to us. Then, would the electrons seem to revolve slower? Is this the reason why electrons seem to move so fast around the nucleus? To make it more understandable I have an example:- The earth seems to move rather slowly around the sun to us even though it has a large velocity. I think this is because we are very small compared to its orbit's radius. If we suddenly grew to a size so big that the solar system would appear as an atom to us, then will the earth appear to move so fast that we will not be able to calculate its position as well? please help me with this. If there is anything wrong with my question or answer, then please correct me. Give me suggestions on how to modify my answer. It will be helpful if I get the answers soon. Thank you.
