| No, but it is quantum fact (unless something changed very recently) that you cannot know the position and speed(?) of particles like electrons that are so light that light actually affects their position. If you measure their position their speed/direction changed, if you measure their speed, their position just changed. I do not see where this makes anythin irrelevant, we wish we could measure both but at the moment that's impossible, the particles are still relevant, and if we figure out a way to get both, that info would also be very relevant |
