I'v been reading this book on Physics, and have been wondering about what the Author(Michio Kaku) said in one part of his book. Michio was refering to how we lost the abbility to see in the 4th dimension because of evolution, since in fact, seeing in the 3rd dimension had an advantage. Seeing in the 3rd dimension ment seeing everything physical, such as a limping lion, or an enraged elephant. So think about it like this, a person who can see higher into the 4th dimension than the 3rd, walks past a lion who hasn't eaten in a few days, the human doesn't notice while the lion sees an easy meal. Since the human has a low view on the 3rd dimension he wont notice it as a lion sits there, which means the lion's eating out at the moment. Yet someone who has evolved to see the 3rd dimension clearly, loses the vision of the fourth dimension. So if we have evolved to only see the 3rd dimension, what would come out of being able to see in the 4th dimension? In other words, how would we benefit from looking into the 4th dimension instead of the 3rd, and what would it look like? I'm just asking this from my point of view, please reply with what you think we would see, please don't make it stupid.
PS. The book is called "Hyperspace" By. Michio Kaku
