Time - the past, the present and the future

Is there a paradox in time. Can one go back in the past and kill himself? If this can be explained, then Einstein's theory of relativity must be a simple matter.

If you understood the manifestation of the balls as matter, then you can imagine that the orderly creation of matter by the moving balls manifested differently "over time" is what we refer to as time. Time does not really exists, it is a human created standard. We can actually say that the past, the present and the future exist together! Time is just a different view of the arrangement of the "balls". The balls can be arranged for one's future self and past self to co-exist. If this is possible, then Eisntein theory of relativity is very possible. A man who goes on a journey through space can come back to find the world he left to have aged faster.

If you extend the thinking that our universe is just made of the clumping of the balls together, then you can say that our whole universe is temporary. Our existence is temporary!
