Space
Space as slices of spacetime
- Matt Strassler says that space is a slice of spacetime.
- if so, how many dimensions those slices have?
- Apparently 3 dimensions
- Apparently 3 dimensions
- I think those slices are surfaces how can they have dimensions?
- But these things have been developed by very intelligent people who are masters of rhetorical sleight of hand so they can explain anything
- if so, how many dimensions those slices have?
How do we measure space?
- Or, how do we know space?
- It seems that we don’t know something called space because we measure length
Space, dimension, coordinates
- Space appears to be related ta dimension or coordinates
Spacetime is too complicated so let’s study space and time separately
- I think this what Dirac did and he divided spacetime into space and time by using mathematical tricks usually called Hamilton formalism
If anything space must be curved
- I don’t know what that means but we know that all motion is curved or circular
