Greetings to all,
I realize that there is another "dead thread" about this subject (with a lot of interesting comments) but I think I can add a "new dimension" to the conversation. I have also put this question out on a few other Science Forums...
The human eye is much like the lens of a camera, telescope or microscope. An image, as it passes through the lens, is projected onto the retina upside down and backwards. It is the brain's job to sort out and make sense of the image entering through the eye.
Most doctors agree that newborn babies see everything upside down for a "period of time" - but no one really knows for how long. Since gravity determines "up" and "down", wouldn't the baby have to be able to at least hold it's head up to begin to sort things out? And wouldn't left and right logically follow after that?
