Single Idea 14735
[filed under theme 27. Natural Reality / C. Space / 6. Space-Time
]
Full Idea
Unlike time, space has three dimensions and lacks a distinguishing direction; unlike space, time seems to be specially connected with causation.
Gist of Idea
Space is 3D and lacks a direction; time seems connected to causation

A Reaction
These strike me as nice reasons to doubt (what I already prima facie doubt) that there is a single manifold that is 'space-time', for all that twentieth century physics tells us it is so. A century is a mere click of a clock where truth is concerned.
