What time is it?

Somebody recently asked us if time exists. They weren't talking about 'clock' time. They were talking about natural time. Is there any proof that time as a dimension of space/time, as the engine behind entropy, as the harbinger of  life and death and everything in between actually exists? Some would say that time exists simply because we cannot go back and relive the past (except perhaps as a memory, which isn't quite the same is it?) Others would say time exists because of cause and effect. The cup does not break and then fall off the table.  Time travel is possible, or at least communication through time. Why? Because you are reading this AFTER it was written. So in essence we are communicating with you from the past. It is a hot Sunday afternoon here in the past. We hope it's cooler where you are reading this. Scientists have believed time exists since Einstein postulated about traveling faster than the speed of light. (Which he believed to be impossible.) Extremely accurate atomic clocks have been placed on the space shuttle and have proven his theory about time dilation. The faster you move the slower time moves. It's proven. Are there any practical applications that this idea could be used for? Possibly in communications. Scientist have experimented with a process know as Quantum entanglement. And have proven that instant communication would not only be possible. It could be used to communicate instantly across vast regions of space. The technology requirements for this process are expensive (it requires a nuclear accelerator) but the theory is sound. Somebody once communicated to this writer from the past, they wrote on a bathroom wall, "Time is natures way of keeping everything from happening at once." and someone wrote later in marker, "Space is natures way of keeping it from happening in the same place." Both true statements. Imagine for a moment if you left some sort of trail behind you as you moved from place to place. And everyone could see the paths you have taken in your life. If time travel were possible, could a person cross that path and talk to you from your future. (It helps if you think of the moment of your birth, and then your existence in time as a long pink worm tapered at the beginning of your life, and slowly growing larger.) When you think of it this way, where you are now is as far as the worm would go. Therefore future time travel would seem unlikely, if not impossible. Some of us here at The Crazy do believe that time travel is impossible, simply because if it were, even in the future, than there would be people popping in and out of our time to view important events. (Didn't see lots of futuristic looking tourists standing around taking pictures of the 9/11 attacks did we?) We have often thought about time travel. If you could travel through time, where would you go? Back to see if the Biblical Christ actually existed, and did he die on the cross? Was there only one shooter that day in Dallas when JFK was shot? What would happen if you killed Hitler before the Beer Hall Putsch? If time travel were possible could we change the future? Or would we just create multiple futures as some people theorize. These are questions we may never answer. But it's interesting to think about them though isn't it? That's it for now. (oops "now" has become "then" before we could even type it down.) See you in the future. Ciao for now.
