Observation and measurement

Classically, for a particle, you have a clear idea of where a particle is and how fast it’s moving. And you can measure whatever you want.

However, there is less agreement on what quantum mechanics is saying because you have to use words like "measurement" and "observation." You can observe things such as the position or velocity of a particle, but can't measure it.

When you extend that to gravity, things like location in space don’t exist. They are some approximations that you get at the classical level in the right circumstances.
