““A space that is empty in the sense that it doesn't contain masses is nothing but a special case of the above. Looking at it from the four-dimensional vantage point, space and time are interwoven according to the laws of special relativity theory. Space proper is Euclidean in its limit of vanishing gravity-trajectories of free fall are the straight lines already known from Newtonian physics. I will not go into detail considering space and time together in that case. Suffice it to say that this "empty space-time," too, can be described by a field; it is just one specific case among many others, and doesn't stand out.””
About This Quote
This interpretation was drafted with AI assistance. It is one reading of the quote, not the author's own explanation.
Empty space is still a field described by relativity; it’s a special case where no mass is present.
In simple terms: Even without mass, space‑time follows physical laws.
Key Takeaway
