The Question of Time

I am intrigued by the concept of time. We tend to believe, in support with the scientific facts that we are on a linear path of progression since the event of the big bang 13.7 billion years ago. It gives us a mental perception of time as a straight line where we are at the far end of the time as the time is ticking away. There are many problems with this view. The first is the assumption that the universe has evolved, and is evolving, only in one direction. The second is that everything that is contained in the universe is contained within one time moment – that is, the whole universe as a big, singular blob expanding in one direction.

The problem with both these views is that if we were contained in that blob, then the perceptions of past and future would not exist. Einstein wrote in Relativity;

Since there exists in this four dimensional structure [space-time] no longer any sections which represent “now” objectively, the concepts of happening and becoming are indeed not completely suspended, but yet complicated. It appears therefore more natural to think of physical reality as a four dimensional existence, instead of, as hitherto, the evolution of a three dimensional existence

This implies that in Einstein’s space-time structure, there is no division of time; and that past, present, and future are all a singular existence. That holds true if we assume the universe to be a big singular blob with the whole time contained within the blob. My question is;

Is the point/event of big bang – the starting point of time – contained within the universe or outside the universe?

In other words, is the universe expanding upon itself – one point of time that itself is evolving and expanding, or is the universe as an entity has moved away from the point of creation. Imagine blowing a bubble from a tube with the tip of the tube being the point/event of big bang. Is it that this point where the bubble came in to existence is constant and the bubble is expanding around it? Or, the bubble has left the tube and flown away in the air? The second theory would hold two premises. One is that the universe is travelling in time as well as expanding in its own right. The inference of such premise would be that there are two different time frames – time from the big bang to the current state, and the time within the bubble.

There are problems with both these views. If we hold the first view true, which I believe is the scientific view as well, then we will need to visualise ourselves as one of the droplets that was created in some point of time. The fact that today we are able to witness the light emanated from dead stars millions of years ago is indicative of things that existed before us. This means that various objects exist at various times in the universe. In 2007, measurement of radioactive elements such as thorium-232 and uranium-238 on a star in the Galactic halo, HE 1523-0901, indicated that the age of our Milky Way Galaxy was approximately 13.2 billion years, almost the same age as the age of the universe. If true and substantiated, that would imply that we are almost close to the surface of the bubble (metaphorical assumption as no boundaries are perceived in the universe). What then, of the things that were created “after” us. There are supposed to be approximately 200 billion galaxies in the universe. All could have not been created at the same time (or we would not be able to witness lights from long dead stars) – the whole bubble cannot just come into existence in one instance. That would negate the evolutionist theory. Therefore, since we are able to feel that we had a past and will have a future, we must be bound by time. But, is this time the same time frame as rest of the universe? In other words, would a person living on Pluto age at the same rate as the Earth? I do not think that we have the answer to that as yet. If yes, it would mean that the universe is not really expanding but rather creating an impression of expansion by its forward movement. If no, it would mean that we are part of a maze of time dimensions.

In the second view, universe is moving away, and expanding in its own right. That would mean that we have two frames of reference; one our own time within the bubble (the first view) and the second time frame within which the bubble is moving. Within this view, we have moved away from the point/moment of creation are looking back at history of the universe. This view create the impression of a singular but expanding universe moving away somewhere in time. What then, about all the space around us? There has to be a distance else the formula for velocity will not hold true. If there is time, there has to be distance.

I believe that the movement of the universe is not linear. It is moving in a circle or a spiral, same like our galaxy within it. And, we may, in our current state of existence, could be anywhere on that circle or spiral.

More on it later on. Your thoughts are welcome.
