infinite distance: the dot is in the midle of the intersection
and why every cartoon is crosseyed, could actually be more atractive for being the natural way?
also probably the metals we ingest screw our vision  |
I think your logic is a bit wrong on this one.
How can two eyes 2cm apart measure the distance to a star that is 2 million light years away?
That's 14,696,563,427,345,637,530 miles away. Give or take a few..
The number above is... deep breath...
Fourteen quintillion, Six hundred and ninety six quadrillion, five hundred and sixty three trillion, four hundred and twenty seven billion, three hundred and forty five million, six hundred and thirty seven thousand, five hundred and thirty miles.
They currently use parallax to measure up to a couple of thousand light years, after that it becomes such a small movement that it's undetectable. From there onwards they are pretty much guessing. (There could be as much as a 20% error margin for distances over a few thousand light years)
So no, I don't think the Mayans could measure stellar distances. We can't either.
