The vast majority of lifelong vision problems are due to inadequate bright light in the first year after birth. The eyes growth is inhibited by bright focused light. Which is what makes them grow until focused. If the light isn't provided them the eyes grow too large and cause nearsightedness.

That constancy of the heavens is something I think we take for granted. Before Galileo and his work to improve the telescope, the heavens were seen as immutable: unchanging. It's difficult to imagine how odd it must have been to see changes happen before the telescope. Most of those would have been temporary, such as comets and nova changes to brightness. They would have really seemed like messengers.

I just finished reading "The Milky Way: an Autobiography of Our Galaxy" by Dr. Moiya McTier, she was the first dual major of astrophysics and folklore from Harvard.

She keeps it pretty high level, but touches some on the connection between primitive humans, astrology, folklore, and it's progression into astronomy. It's a very well written book, has a lot of info on Galaxy formation, star formation and types, age and shape of the universe. It wound up being a lot more detailed than I thought it might be.

Them putting up that massive shade sail was a way to stop people from looking up and trying to make connections. They want us to think these were made by hunter gatherers and the animals carvings are nothing but that

In a quite literal sense....it seems nearsightedness happens because children spend more time indoors, in conditions of indoor lighting. Indoor lighting is a whole lot dimmer than outdoor light, and that means the signaling process the eyes use to control their growth doesn't work properly.

For 500k you could buy a house or live off the interest. If you can afford it, go ahead. Me, I’d pay off my house and spend a week in Vegas.
