Time & Light Dilation in Black Hole-An Understanding of the Known and Unknown Facts

Abstract

Understanding time has been quite a challenge for human being. Though we in general understand time but its im-plication for physics and the universe just make things very murky. In this paper we will discuss what is the relevance of time in the study of astronomy and how it impacts the Universe. The great physicist Einstein has to be credited for introducing Time as one of the dimensions and after that the whole concept of looking into time has totally changed. We have understood space and time have an integral collaborative part to play in the vast Universe. Not only that through general relativity we have seen how time interacts with gravity and how time can be distort-ed by gravity. From the simple watch on our hand time has taken a great leap and made a mark of its own. Not to say the behav-iour of time in certain celestial bodies still makes us wonder are we missing some aspect of time. Time acts peculiarly inside a Black Hole and forget Singularity as the concept itself puzzles our knowledge of physics. The concept of time as one of the di-mensions has opened a lot of new avenues of re-search but also has bought with its lot of unanswered questions. It does not stop here when we try to analyse past, present and future with time though theoretically may be very easy to understand but once we add physics into its things get a bit complicated. The stars that we see in the night sky is actually past whereas the person travelling in space is future and we are present. This paper will try to see if events can be placed in time and how light brings those events into our understanding. It must be understood that any event that is observed by human beings is due to the fact that light is falling on that object. In Big Bang several events happened in the beginning before the commence-ment of photon or light that does not mean time had not started. So, it is clear that light and time is not correlated though for hu-man beings to look into an event light is of course needed. This paper will try to analyses the time and light dilation in a Black Hole and how that influences the concept of time. Also, this paper will try to understand how much more research is re-quired to understand the whole concept of light, time and Black Hole.
