How did Isaac Newton know that there was no air in space? Wouldn't

Torricelli had already invented the barometer and worked out air pressure and the vacuum. So the idea of vacuum in space was already in the air.

so they basically knew that air pressure gets lower, the higher you get, and thus they extrapolated that at some point air pressure is basically zero?

There's a good page here:https://www.aps.org/publications/apsnews/201210/physicshistory.cfm
It seems Pascal got pretty close.
