Sarte is criticizing Camus for non-existing God. As if his 'nothingness' exists.
There is no 'nothing' in the universe. Space or vacuum is not 'nothing'.
Nothingness is an invention, like God.
I don't think these people were aware of what Einstein did.
Not understanding what Einstein did caused Lacan’s geometry and ‘real’ too.
Geometry is not real until you prove it like Einstein’s geometry.
There is no 'geometry' in the psyche.
