Hi all, for some time I have been wondering about something I’m not too sure on. Please could someone tell me how randomness can exist? That is to say on a molecular level, or on any level things happening without cause or justification? Patterns may be too hard for us to currently understand or predict however it would be wrong to say because of that randomness exists. In a universe described by some driven by chance some have said anything can happen. I once heard a scientist say in all seriousness say there’s a chance we could disappear and reappear in mars then reappear here. Would like an explanation of how true randomness can exist. By saying that there’s a chance anything can happen your implying there is randomness on a large scale, also in a more Newtonian universe there can not be infinite dimensions, parallel universes because things can only ever happen one way.I believe that if something moves on a molecular level it’s because of forces acting on it.
