    Question about uncertainty principle
    Hello everyone !!

    According to the principle of uncertainty , does it mean that when we measure the Position, then there is no momentum , or it means that the momentum exixts but We can't meaure it at the same time ?

    It means that we cannot know the uncertainty in position and momentum at the same time basically, so both can exist, but can't be measured at the same time So yeah, your latter statement is correct

    The principle is that the more accurately you measure one, the less accurately you can measure the other.

    Thus, if you know the position really well and precisely then you know the momentum very little.
