16 ideas
Space alone, and time alone, will fade away, and only their union has an independent reality [Minkowski]
Space-time arises from the connection between measurements of space and of time [Einstein, by Farmelo]
We can't think of space-time as empty and propertyless, and it seems to be a substratum [Martin,CB]
Space-time is indeterminate foam over short distances [Close]
We distinguish time from space, because it passes, and it has a unique present moment [Le Poidevin]
Time, as it appears in standard modern science, is bad verificationist metaphysics [Smith,Q, by Le Poidevin]
Space is 3D and lacks a direction; time seems connected to causation [Sider]
The central question in the philosophy of time is: How alike are time and space? [Sider]
Modern metaphysicians tend to think space-time points are more fundamental than space-time regions [Hawthorne]
Spacetime may well be emergent, rather than basic [Ladyman/Ross]
If spacetime is substantial, what is the substance? [Ladyman/Ross]
The universe expands, so space-time is enlarging [Bardon]
Relativity makes time and space jointly basic; quantum theory splits them, and prioritises time [New Sci.]
Space-time may be a geometrical manifestation of quantum entanglement [New Sci.]
Einstein's merging of time with space has left us confused about the nature of time [New Sci.]
In relativity space and time depend on one's motion, but spacetime gives an invariant metric [Baron/Miller]
