I woke up today and for some unbeknown reason I had all these weird thoughts in my head. It all began a few years back, but really came back to me the other night when I was watching a film about aliens.
Yes, I know how it sounds. Aliens, weird people, conspiracy theories and whatnot. But it really is something else.
The film I was watching began with a quote by Arthur C. Clarke: "Two possibilities exist: either we are alone in the Universe or we are not. Both are equally terrifying."
I don't know about you, but it really bugs me that people take it for granted that aliens don't exist. And I should perhaps abandon the use of the word "aliens" as it implies something something I don't mean to. You see, "aliens" to me can be any form of extra-terrestrial life, and it seems weirdly normal that extra-terrestrial life should not only be immeasurably more advanced than us, but it would also be playing around on our planet. Perhaps it is a perception too similar to the one we have of teenagers, wouldn't you agree? You give a teenager a smartphone with more CPU power than my first and second computer combined, and what he does is play Angry Birds in HD mode.
I guess what I'm saying is that it seems rather improbable, let alone impossible, that we are alone in the vast span of the whole Universe. Scientists have already discovered other planets with Earth-like features which would be suitable to support life as we know it. Life as we know it. Life as WE know it... Hmmmm...
What do we know about life? What IS life? Why are we considered alive and other things not? We do have organic chemistry, we do consider all life to be carbon-based, we give great weight to proteins and try to find traces of water on places very far away. But what if life does not exist only in the way we know it? What if there are other possibilities, other viable environments? What if other forms of life exist, forms we can't even perceive? It is common sense that we would not be able (probably) to interact with such a form of life with techniques currently available. Imagine an entity living in an environment completely devoid of oxygen and hydrogen, feeding off metal-based alloys and thriving on naturally occurring electricity discharges.
I dare say that the basic compound of life as we know it is not carbon, it's electricity. Even if we are so different from "soulless matter", the soul itself is not contained in our material body. Otherwise, we would be immortal. Life ceases when the brain stops functioning, ultimately. And it can be caused by a variety of factors, but the result is one: no signals are conveyed, there is no flux of electrons, it's like we are out of battery.
So, if electricity is what makes us tick, why wouldn't it work on other environments as well? We only need oxygen so that the brain, our current functional headquarters, as well as every other subsystem, can meet the challenge of surviving in the state it has been created. There is nothing more to it. It just doesn't know anything different. What would happen, though, if it were created under different circumstances? Would it be able to contain electric charge and use it in a manner so that it could be classified as "alive"?
It must be an old question, and Frankenstein is a proof for this.
What I want to say, in the end, is that perhaps we should keep an open mind. Consider when people didn't know that the world is round. Consider when they didn't know that we revolve around the Sun, and not the other way round. I think we ought to have more than enough proof to make us consider our options twice, yet we seem to hold on to whatever we already know, and exclude new possibilities instead of examining them based on our knowledge.
This morning, as I said, I woke up in a strange mood, and started reading online about String Theory. For the theory to hold, it says, we need a space of higher dimension, namely 11, if I am correct. And everyone loses their mind.
I was TA in my time in University. Trying to explain in a Programming class what multi-dimensional arrays are, I confronted the limits of my colleagues as well as mine. How does one understand what a multi-dimensional array is?
We all know what an array looks like. It's rows and columns, spanning for as many elements as we need. And we all know that this is a two-dimensional array. Then, how do we add a third dimension?
Well, I presume you've at least once worked with Microsoft Excel or a similar package. Have you noticed the small tabs indicating the spreadsheets? So, by going to a different sheet, you have a whole new table to work with. There you go, a third dimension.
If you add workbooks to that, you have another yet dimension: every book has its sheets, and every sheet has its own table.
What if we have a folder in which we keep the books for every year? Then we have another dimension.
I could go on, but I think you got the message. We need practical examples to be able to make things work in our heads, but sometimes it's not as complicated as it seems. We just need the right perspective, I guess. And perhaps the 11-dimensional space is not such a crazy theory, given our own limitations. We can't even directly see the whole spectrum of the light around us, let alone perceive the grandeur of the space that we live in!
But hopefully the people that prefer to use their intuition and put their minds to work will have better results than my random thoughts. I can only hope I've gotten you intrigued and not bored.
