The Upside Down World - Is It Real?

[.:superfry:.]

i was just thinking...and its probably totally wrong...but I've asked my physics teacher and she's just like..."next question please"...
if our eyes see things upside down but our brain interprets them the right way up (or is that just in babies??)...but yer if our eyes n brains do that...does that mean that really the world is like upside down or something and like in stead of gravity going downwards its really going ^^^ or like or its still going down but becasuse the world is upside down its realli going up?? i don't know i confuse my self!
but yer just wondering...and sorry if that didnt make any sense at all!

Welcome to PF

the world is prefectly like what you see, upright. But when the image is formed on your retina, it is upside down, just that our brain is able to interpret it correctly, that's all. BTW when light(the image) passes throught the lens of your eye, the light is twisted upside down and hence image form on your retina is upside down.

OFF TOPIC : your teacher shouldn't really snub you like that, what a unprofessional teacher you have.

I can assure you that the world is not upside down. Our eyes do not see things upside down, they actually see things right side up. The misconception that our eyes see things upside down comes from the fact that the image projected onto our retina is inverted, but our brain automatically corrects this and interprets the image as right side up. This ability is not just present in babies, it is present in all humans.

Gravity is a force that pulls objects towards the center of the earth, and it is a fundamental force of nature. It is not affected by the orientation of the world. So, even if the world was upside down, gravity would still be pulling objects towards the center of the earth, not upwards.

It is important to understand that our perception of the world is not always an accurate representation of reality. Our brain uses past experiences and knowledge to interpret the information received from our senses, which can sometimes lead to misconceptions. However, scientific evidence and experiments have shown that the world is not upside down and gravity works in the way we understand it to.

I would recommend discussing your thoughts and questions with your physics teacher, as they can provide you with more accurate and scientifically supported information. It is always good to question and wonder about the world around us, but it is also important to seek out reliable sources and information. Keep exploring and learning!
