مکانیک کوانتوم، اینشتین و ساختار فضا زمان

Space-time is very strange in quantum mechanics. It remains continuous but it has a peculiar connectivity because of quantum entanglement. In classical physics and relativity space is separable. You can fully describe what happens in any localized region over a brief time interval without taking into account distant events. This is not possible in quantum mechanics.

Einstein:
"I consider it quite possible that physics cannot be based on the field concept, i. e., on continuous structures. In that case nothing remains of my entire castle in the air gravitation theory included, [and of] the rest of modern physics."
