Space-time, philosophy: space time is a three-dimensional space with time as a fourth dimension. The fact that time is interpreted as a dimension distinguishes the space-time from multi-dimensional mathematical spaces, in which time plays no role and which are therefore structured differently. In particular, the space-time has no measure which can equally be used for spatial distances as well as for time measurements. See also relativity theory, four-dimensionalism, world lines.

Bertrand Russell on Space Time - Dictionary of Arguments

II 50f
Space/Time/Space Time Continuum/Relativity Theory/Russell: new: space and time determinations are no longer independent of one another. If you change the type of space determination, you probably also change the time interval between two events - or if you change the type of time determination, you might change the spatial distance. There is no universal time any more - only when two bodies are at rest, their proper times match. Def clearly earlier: is an event if it can affect another. Graphic/(s): is two circles around two dots - points of intersection: happen at the same time - for someone in the intersection: Both events were observed - depending on whether closer to A or B, the corresponding event is observed earlier.
II 68
Def Spatio-Temporal Distance/Russell: you take the square of the distance between two events and the square of the distance that light travels in the time between the two events - then subtract the smaller of these numbers from the larger one and define the result as the square of the distance between the two events. This distance is the same for all observers and represents a true physical relationship between the two events, which is not the case in temporal and spatial distance - General Relativity Theory: the concept of distance must be further generalized.
II 115
Space Time/Time/Momentum/Mass/Relativity Theory/Russell: if we replace time with space-time, we note that the measured mass (as opposed to the rest mass) is a quantity of the same kind as the momentum in a given direction: you could call it momentum of the time direction. The measured mass is obtained by multiplying the invariant mass with the time that elapses when covering the distance. Momentum: is obtained by multiplying the invariant mass with the distance.
