Is time travel possible? Will there ever be a moment when we can say, for definite, that time travel can be achieved? This article will look at whether or not, one day, we will be able to travel through time. For this to happen we need to understand the 'concept' of time and of how time and, indeed light, works.

Because of the way light travels we are always looking into the past. So, for example, if we gaze into a mirror and view our own reflection, we are indeed gazing back into the past. Why is this?  This is because of the way light travels. The closer we are to an object the smaller the changes are. Although the changes are so minuscule that we do not notice them because we are so close to that object - our reflection.

However, the further away we are from an object the longer it takes light to travel from that object to us. So, therefore, we view that object from its past - such as when we gaze at stars. When we look at the starry sky, we are not looking at the stars as they are now...but as they where in the past.

Again, this is because of how light travels. The further away an object is, the longer it takes the light from that object to reach us. Therefore when we look at a star we are gazing into its past - as explained above. This is the pecularity - and one of the quirks - of how light travels from one object to another. 

Whatever you are doing right now - right at this very moment - time is always moving, ever forwards,  What you were doing a few seconds - indeed milliseconds ago - has now been confined to the past. The present, is fleeting and is only with us for a moment. While the future is a millisecond away, upon reaching an object the process turns full circle and starts all over again.

According to Einstein's Theory of Special Relativity, as an object approaches the speed of light, that object begins to slow down. This theory opens up a whole new concept. It means, that an object traveling FASTER, then the speed of light, could open the door to time travel into the past, as well as the future.

The one major obstacle to this theory is that the speed of light is the highest speed to which, an object can travel. This makes it very unlikely that we will be able to travel into the past. But the future? Well, that could be a different story. 'Time travel' into the future could, one day, be made possible. This is because it is easier to travel forwards, then backwards, into 'time' and space.

Is time really the '4th Dimension'? That unknown dimension that is such a mystery to us all. Will we, one day, be able to create a machine that could take us backwards and forwards into different time periods - or indeed, different dimensions? More likely, time travel will become a natural phenomenon. A sort of 'wormhole' 'black hole' - or maybe, even 'cosmic strings.' Whether these things exist or not, that is for us to find out.

When stars that are more than four times the mass of our sun have reached the end of their life, they begin to burn up their fuel. Swelling to an enormous size before collapsing under their own weight. In other words, they turn supernova. The sheer power of an exploding star sometimes causes a 'rip' in space. This 'rip' becomes a black hole. The gravitational pull of a black hole, on any given object, is so powerful that it can swallow up whole galaxies. Even light, the fastest thing known to us, cannot escape the pull of a black hole.

With this being the case, mathematicians and scientists have often wondered whether or not 'black holes' could be used as some sort of 'time portal.' Indeed, there are different 'types' of black holes. A 'non-rotating' black hole is called a 'schwarzschild'. This was named after the German astronomer, Karl Schwarzschild. In this type of black hole, all matter is crushed beyond existence.

Another type of black hole - a 'Kerr Hole' - could be theoretically possible. These types of black holes are 'rotating' black holes. In theory, they could be used as 'portals - portals' for time travel - or travel to parallel universes. This bring up a whole new set of possibilities. If Kerr Holes do exist, it could be possible to pass straight through them and exit, out of a white hole.

White holes work in the complete reverse to black holes. Where a black hole swallows everything in sight, a white hole would spew out negative matter away from it. In theory, these white holes could be our entry into 'other' times, or 'other' worlds. But, is it right? Would it be right to  travel back in time to when a major disaster would be about to occur?

Would it be rightto stop that disaster from happening?  Some people would say a resounding 'yes'. But what would the long-term affects be?  Even though in our minds, it would seem right?  Would it be right to kill Hitler - or any other despot as they would be  babies?  Killing them as babies we could be saving millions of lives in the process.

Imagine the countless lives that could be saved by somebody going back into a certain period in time and altering it for the better?. Altering it to such an extent that disasters would be averted. Yet we do not know whether this would actually be the end result.  But this could also work the other way - imagine what such a power in the wrong hands could do?

The answers do not bare thinking about. For where such evil people went wrong before, now, with such a power, they would have the benefit of 'hindsight' and that indeed, would be a terrifying prospect.  The human race stands on the threshold of a brave new millennium. New technologies are being created - seemingly - daily. 

We are striving to break the boundaries of human existence in this present time period.. Should, one day, a brave soul or a madman, discover such a power as time travel, then that day could be the 'making' or 'breaking' of us. What do YOU think?
