I registered only to post this question as it's bothering me since yesterday. So.. I was watching Discovery Science and saw in a show that scientists are trying to send info in the past. A guy was saying that when this will be possible, they will be able to send messages back in time and prevent many major events that happened in history. Now this is where I don't understand it anymore. How come we didn't receive any message from the future? Our present and our past is the past of their future. Hope you understand what I mean. ( English not my natural language ) So how come all the major events still happened if "we" from the future didn't send any information back to the present ( past )? Or did they go "Oh let's not alter the history, it can be dangerous". Also, if the scientists will ever discover time traveling or sending info back in time, shouldn't we receive their test messages or something? For me, it doesn't seem normal that they discover, let's say in 50 years, the time machine and don't use it to send people back in time for research. Of course I don't expect to see someone on TV saying that he is from the future, and if I would I'd say that most probably he has problems. Sorry for repeating myself, as I said English is not my main language and I'm not a scientist. ( not even close to become one ) Anyway... what do you think?
