Let me understand this I am more confused than ever. Here is my question: You have a time machine. You get a pound of gold. You put it on the table. Then 10 minutes later you put it in the time machine and send it back ten minutes. Does this mean that at (T-10) minutes you see two pounds of gold? Irrespective of whatever time line you are talking about, you will have two pounds of gold, correct? And if you keep repeating it, then soon you will have a ton of gold. That means, you are creating matter out of nothing, or did I miss something here?
