I recently had a discussion with my brother regarding knowledge, the universe, science, etc. and it stirred my dormant brain once again.
The thought that the human brain is capable to contain ideas like quantum physics, multiverses, and just knowledge in general probably all boils down to how we can quantify and observe things as human beings, given tools we can only contain with our basic senses.
We can assert to the fact that deities don't (or do) exist. But this is only true due to the fact that we can't fathom or quantify the ideas that we have. The knowledge bias that we gain is true because we have a certain tendency (or influences) to believe so. Great figures that lived during the great periods and those that are still breathing today may claim that the universe is expanding or that a god is watching over us - that will only be true once we conceive to the idea and we believe that it does. The facts that we are currently presented now are, for me, illusory perpetuals of what our mind can munch on. The human brain is a very powerful, complex, and beguiling piece of matter. It controls you, your reaction to facts, your reaction to the so-called space around you, it controls everything a human can process on. Everything we say or hear from other people is an opinion and that goes with the fact that everything we see is a perception.
What if all these things are not, cosmologically speaking, real at all? And by real, we then go back to ascribing via the facts we have gathered and experienced. What if the text (that's what we humans call it) you see on your screen is not there at all? What if the blood that spurts out or flows to your vessels is not reddish in color but is transparent? What if our vision, hearing, and other related senses is a jumble of other things? But these are all possibilities imposed by my gentle brain. And these 'what ifs' are yet again a superimposition by the collective conjugation of my brain's neural activity. Currently, we are constrained by what we can sense and observe. We claim that the universe is expanding (or maybe shrinking), because that was what our scientific observations has told us and the traces from the past has given us. But we don't know what we really know. What if there's a more profound way of observing the observable than we humans do? But knowledge itself is an empirical ascription.
We know that dinosaurs once existed, we know that we humans breathe in oxygen to our system, we know that water is liquid, we know that by moving, we can travel, we know that light travels faster than sound, we know that light can bend, we know that there are billion galaxies out there with a quantifiable number of stars and systems. Why? Because it is what our mind can contain and it is what has been factually observed throughout the centuries. There is entropy, which can explain (as human understandable as possible) why we're born as babies and die old and the concept of a past, present, and future. However, it is really impressive how the human brain and understanding has evolved through the millenia and it never ceases to amaze me.
What I simply wanted to share is that there is always a possibility to everything, or probably the impossibility that comes along with it. I may not live old enough to witness the possibilities emerge but one thing is for sure, the human mind will always be trapped by the thoughts it concurs.
