The Principle of Uncertainty: An observer can not simultaneously know the position and momentum (velocity) of any particle to absolute certainty.
Consider the following Case: I want to know the position of a particle but can only detect the particle by bouncing photons off of the particle
BUT: this uncertainty is an intrinsic limit in nature, not an artifact of measurement.
As soon as I have detected the spatial position of the particle, momentum has been transferred to the particle and its position has changed
ImplicationsImplications
At any given time, one particle can’t precisely know At any given time, one particle can’t precisely know where another particle is where another particle is quantum tunneling quantum tunneling results results no energy barriers no energy barriers
Cat Cat exists as a quantum superposition until an exists as a quantum superposition until an observation is made (the Copenhagen observation is made (the Copenhagen interpretationinterpretation).).
