There's one world and it's round
- This page is not currently titled very well, but the point is that from the right hemisphere's reality-oriented perspective, everything is all happening as part of one happening, all in contiguous physical space.
- (This is true about time, too. Everything that has happened and will happen is all part of one timeline)
- This is obvious, conceptually, but most people don't actually feel the embodied reality of it most of the time.
- Most people don't really feel the reality of that, and one way to demonstrate that is we don't usually have an intuitive sense that eg when we're on a call with someone:
- there's a direction we could point such that the straight line from the tip of our finger would be pointing at them
- and unless they're in the same city as us...
- the direction to point is somewhat downward due to the curvature
- eg 100km is nearly 1km down
- note that this is extremely nonlinear:
- 200km is over 3km down
- 1000km is 78km down
- the direction to point isn't due east/west even if we're both on the same line of latitude (unless that line is the equator) since the other lines of latitude aren't actually straight lines on the surface but rather curves
- this is sort of obvious if you imagine you're each standing 100m from the north pole, such that the triangle of you two and the north pole is 90° at the pole.
- "up" is at a distinctly different angle for them than it is for us
- Jordan Hall on Voicecraft podcast episode from Sept 2020
- the whole episode is broadly relevant
- minutes 35-40 or so are particularly relevant as they discuss how communicating digitally is still fundamentally going through the physical world
- re earth curvature in particular
