- Look into the past. Before us there were apes, and still before the single-cell life evolved(?) from the organic broth. Long before that the earth came into being. The earliest we think back upto is the origin of the Universe itself. The Big-Bang theory and the Steady State theory. Ever thought whether Universe is just the name for the matter or whether it also includes the space in between. I think it should and then the question arises as to what was it like before the so-called Big-Bang? To whatever extent we think, one can ask what was it before that. It never ends.
- Look into the future and the same thinking can be repeated here too. What next is the question here? No end is visible here too. In fact there cannot be an end to it.
- Now move on from the domain of Time into the domain of Space. What is outside the earth, and then the galaxy? If you think it's the Universe, then what's outside the Universe? Is that also defined as the Universe? If so the villain of Infinity again obscures any possibities of knowing the ultimate truth here too.
- It's not over. Start looking inside. It's the cells, made up of organic molecules, made up of atoms of elements, made up of electrons, protons and neutrons. What are these made up of Sir? Then we enter into a domain where physicists have started conveniently defining particles and waves aposteriori just to fit the observations. Invokation of the question "What's this made up of?" brings forth the smiling Infinity blocking the pathways of knowledge like the God who told Adam and Eve not to eat the apple.
We live a life of Infinite Ignorance and worse a life of ignorance with no end possible to this ignorance. Do you think we need be confident about anything in this life?
