Assume space-time is quantized. This would mean that space-time is broken up into discrete bits. It then follows that time is broken up into discrete bits. This disagrees with basic experience: we can start counting time at any arbitrary point. “Now” could be any time whatsoever. Moreover, we run our physical experiments at any given point; we don’t have to wait to start our clocks. But what if our ability to run experiments at any […]
