The concept of time is very complex according to me. While it's very easy to say how many hours make a day or how many days make a year, it's impossible to tell when did time begin, at least mathematically. If someone tells me time began when it was time zero my question would be what about the time before time zero? Irrespective of what one tells me I think it's logical for one to ask what about the time before that? The concept of time can be compared with a number line. A number line begins with negative infinity and ends with positive infinity, in between there are all real numbers. Having said so, my statement is actually wrong because infinity means beyond finite. It never ends. It begins from a place which has no beginning and it ends in a place which has no end! I know I am driving you mad now! Sorry for that. Time also begins from a point of no beginning and ends up at a point of no end. Time's begins from negative infinity and ends at positive infinity. I am making a mistake again probably because time never actually began and it probably will not end ever. Trying to find out the beginning or end of time is like finding the a real number solution for root over of a negative number. The resultant number is an imaginary one. There is no real solution. Both science and mathematics are helpless when it comes to the question of beginning or end of time. There are so many complex formulas in science and mathematics, yet the scientists can never tell us when time began and when it will end. Time was there from infinity and it will always be there till infinity. I know this a very weird topic but would like to hear from you people out there about this. What do you think of time? Do you think it ever began and will it ever end? Isn't the vastness of time much more incredible than the vastness of space?
