Well, today's question in HUMA was about people sending messages back through time. I can't remember exactly where this question came from, but in general, we had to answer how we thought it might appear, what implications it would have, etc. if someone from the future were to have the technology to send a message back in time somehow. For my response, I answered that the message might take the form of little things that people consider messages "from God". In any case, the message would have to be as small and subtle as possible; the person from the future sending the message would have to find the smallest catalyst to change in the past, otherwise, the change might butterfly effect and change more than intended. If this were to happen, the future might become worse than intended. Some people argued that it would be best to send a message to the Government, Media, etc, but some, including myself, argued against that for the reason of the butterfly effect again. We said that the message could be anything, either verbal, written, or material, but that material was the least likely. If the message were a material substance actually sent back in time, or a material that was created, that would use up FAR too much energy. Same thing with sending an actual person back in time. Think: sending something or someone possibly thousands of years back in time. We can't be certain, but you might have to rip apart a galaxy or two to create the energy required for that. As for the matter of linguistics in a message, it wouldn't be hard, as chances are we could study the language of the past to communicate with them. If something happened in the course of history that destroyed the record of past languages, pictures would still work just as well. Others argued about the content of the message. Really, it depends on what the future would define as "important". If you're gonna go so far as to alter the course of history about something, it had better be deemed as important. Some argued that it wouldn't be something like "Grandma, don't cross the street today.", as that wasn't important. However, a couple of other people and myself argued that again, you have to define important. If that grandma happened to be able to find the cure for cancer later that day, assuming she didn't cross the street and get run over by a car, then you'd wanna leave that note for her, as I'm sure we could all agree that a cure for cancer is very important.
As for future posts, as we seem to be wrapping up classes here, I'll make some comments about the final essay I'm writing in HUMA. As I said, the prompt is what I think is the best metaphor for time (or at least, the best one that I can stretch to 3,000-5,000 words), and mine is linguistics. Sadly, I've made a TRAGIC, HORRID error in my calendar management, and it's due next tuesday, thursday at the latest, where I thought it was due in two weeks. Oops. So I'll definitely have a post ready by next week, albeit possibly a sleep deprived one.
