God came and said - " same" i have thought about it for quite some time and have also had very serious discussiond running into hours with a couple of my friends? what are physists trying to do - understand nature. what is understand or know ? isnt it fascinating that my understand is the same as yours? we all can understand what is same and different and we all think similarly. when a baby is born, you teach it certain things, and thge same applies to all other babies. i also find that studying how the brain works scientifically and how poeple think is fantastic? try and think about what i said and please reply? you can say anything you want.
