“Chandrasekhar, please come here,” called U.G. leaning against the parapet wall on the terrace. I approached him quickly wondering what he might show me. U.G.’s attention was on the road. The branches of Valentine’s tree spread widely above us like an open umbrella. “Can you see the space between those branches and the vehicles passing on the road?” asked U.G.
“Yes, why not? No matter how bent the branches are, the eyes can see the space between them and the road behind them,” I replied.
“I cannot. All that seems like a two dimensional picture to me. My eyes can see everything in front, one thing after another, but they cannot see the space among them. There are no measurements such as length and breadth, let alone depth. I maintain that the physical eye cannot see the third dimension. Our minds interpret what we see as the third dimension, but the eyes don’t tell us that there is space. When the present-day scientists talk about the fourth dimension on top of the three dimensions, I feel like breaking their teeth. Where is that fourth dimension? I say that even the third dimension is a lie. If Einstein were here right now, I could shut him up in one minute,” U.G. said. With that my mouth closed shut.
