How does the understanding for the size of the world change one's thinking?

What was it like living on the Easter Island, the world a place you can walk around within a few days?

When Einstein developed general relativity, we did not know there were other galaxies beyond the Milky Way.

Most people today don't know how vast the Universe - and yet my own thinking is deeply shaped by being an astrophysicist, by the fact that we are just a tiny memory of a speckle of dust.

The post above ⬆️ was triggered by my morning lecture - I try (and get distracted; and then try again) to spend the mornings reading something - preferably some bits of interesting info, crumbs for the brain hamsters, to have them happily munching instead of running in their little wheels of doom.

This book is a bit challenging - not a lot of info, so I end up getting more background online. But I'm learning a ton.
