I have a theory, or at least a concept I wish to propose on the laws of time. It is my belief that time is unalterable, and that the "future" does not exist. I see timeline as a sort of recorder, and we live on the point of recording, the exact present point. It is impossible to go into the future by any means, because there is nothing before the exact present point, merely "unwritten" time, and because time only records in one "direction" at one point in time constantly, it is also impossible to alter previously recorded time. If time travel to the past was possible, the most we'd be able to do is view the past, and not interact with it in anyway, because time does not "rerecord". My question is does my theory on time hold water? I know that time is a man-made concept, but I'd like to know if it's possible my concept of time is plausible.

You won't be suprised to hear that philosophers disagree a lot about the reality of times. Some say that time is a lot like space, and that all times are equally real at all times. On this view, the present is where we happen to be at the moment, but right now the past and the future are also equally real, much as here is the place we are, but other places are equally real even though we are not at those places. At the other extreme, there are those, appropriately called 'presentists', who think that only the present is real: the past has gone out of existence and the future has yet to come into existence. Your view is intermediate: the past and present are real but the future is not. This too can be seen as a kind of spacial view of time, but in an expanding universe. If it helps, think of the universe as an inflating balloon: on your view the temporal dimension is inflating too, so there are more and more real times.

I too find the expanding view of time attractive, in part because the past really does seem to have a kind of reality that the future so far lacks. But one thing we might worry about is whether this expanding view of time can make sense of the truth of future tense statements. It's true, alas, that I am going to die someday, and I think moreover that it's true now that I am going die. But if it's true now that I'm going die, then is looks like there has to be something real now that makes it true. Yet on the expanding view there doesn't seem to be any such thing, since what in fact makes it true that I am going to die is something that will only take place in the future.
