    Suppose I was to make a time machine. I go back to yesterday and meet myself. So now there's two of me. Then we both go back to the day before yesterday and meet myself again. Now there's three of me. Then the three of us go back to the day before that...etc. Eventually there could be lots of myself.

    The above scenario is impossible because it violates the Law of Conservation of Mass, which says that mass cannot be created or destroyed. If there are suddenly two of me, that implies an increase in the amount of mass in the universe, which is impossible.

    Now you could say, "I'll go back to a time before I was born". That's no good either, because the matter that you are made of today, has been around since the universe began. No matter how far you go back, "your" matter will be there, and you will violate the Law of Conservation of Mass.

    • And if the law is wrong?

    • It's not wrong. It's a law of nature.

    • You're not thinking in four dimensions.  Matter isn't being created or destroyed; merely being moved in time.

    • I agree. If "moving" matter is moved in time, something in the "present" must first give it up to be used by the traveler.

    • Oh it certainly does exist, my friend. That is because i am Einstein in the flesh; past, present and future. Though I do enjoy hearing all of your ridiculous theories based on what I once believed to be true. Here is a little advice: look to the stars, and think about the possibility a second time. Good luck.

    • One of the theory of time and dimension says that, you could only go back to past and observe things, just like a pilot observes things through the cockpit of an aircraft.You really can't alter things as you stay in another dimension, but it's just another theory.
