The human brain is a very powerful organ and also a very complex one that mankind is very to understand fully. It might occupy only a portion of the human body, but without it functioning correctly, it is not just impossible to function properly but also to survive. But what if, the brain was the size of the planet that we live on?
It has been found that this 1.3 kg organ would actually have a weight that would be four times the size of the earth and have a mass equal to the planet Mars which has in reality only a fifth of the mass of the actual earth.
