What is Mass - Really? Do we know anything?


We all know that almost everything in our universe is made up of what we so affectionately call matter. This matter makes up everything we see and use everyday, it even makes up what we've never seen or used. Distant planets, stars and galaxies - all made up of this weird substance. With every physical 'theory' there is always an element of indefinite uncertainty, and yet mass is one theory that we can almost solidly call "fact". Or can we? Have we ever really thought of what mass is? You may respond that mass is what 'is there'. But how do we know 'what's there' is there? Or what isn't seemingly 'there' is in reality... there? What is 'there'? What are 'space' and 'dimensions'? They didn't exist before the universe began. 
Mass, as you can see, is a much more fiddly concept than you might ever imagine. On a large scale, relative to us, all masses obey a set of rules which we call 'forces' and 'physical laws', and yet on an atomic level, electrons do not. They seem to inadvertently flit around, sometimes seeming to be in two places at once! We cannot predict them entirely. Due to this a new theory was developed, called string theory, suggesting that everything in the universe is bonded together by strings so small that if you enlarged a hydrogen atom to the size of the galaxy the string would be only the size of a human hair! This theory may have yet to explain these tricky conundrums which inundate us in the universe. Yet, as with any theory, it is never perfect and there are always questions surrounding it. In fact, all the facts that we learn in everyday life, that we take for granted. All of them, are probably FALSE! They are in reality just attempts at trying to explain what happens around us. You may say that many of these theories are too robust to simply discard as mere attempts! Yet, that is exactly what philosophers and scientists would have said about ancient theories long ago. Back then, everyone believed that the world was the centre of the universe, that everything was made up of just four elements (earth, fire, air and water) and were completely perplexed by why there were different 'types of air', some of which could kill you! In response to these, instead of finding the correct solution, they simply tangled themselves up in knots, experimenting and trying to find an explanation using primitive theories. We know now that if pioneering scientists such as Isaac Newton and Albert Einstein hadn't come about, we would still be living, ignorant to the world around us.

This is why I believe that we have yet to come close to touching the reality of the universe. Our generation is simply another step towards simplifying these many "proven" theories and finding the real answer to life around us. Every generation brings with it new advancements and one day I think that in someone, somewhere's head the real solution will finally click. We are all on a constant adventure of mishaps and discoveries, some completely unintentional, and yet it is these accidents that will one day let us tumble into the bliss of understanding.

It doesn't have to be genial scientists or scholars which make these discoveries. Most of their minds have all been shaped and warped by the theories which surround us today. Most of them will never have the 'ignorance' to question scientific theories. This is why I believe that to advance in science we must all be willing to completely discard all that we have learnt, have an open mind, and fundamentally question the roots of stable theories. Without that there would be no scientific advancement whatsoever. In fact it is not knowing the answer which helps us advance, it is the question. As implied by the word 'creativity', you must 'create' the question to be able to think of finding the right answer. Even then there will always be more questions coming. What's to stop me or you finding the next question?
