Page "Nothing" Paragraph 9

This characterisation of space reached its pinnacle with Isaac Newton who asserted the existence of absolute space.

Interestingly, modern quantum theory agrees that space is not the void, there is the concept of quantum foam which still exists in the absence of all else, although Albert Einstein's general relativity no longer agrees with Newton's concept of an absolute space.

René Descartes, on the other hand, returned to a Parmenides-like argument of denying the existence of space.

For Descartes, there was matter, and there was extension of matter leaving no room for the existence of " nothing ".
