A recent
article in WIRED.COM talked about Time Travel, and the latest philosophical thoughts about it, but it is the reader's comments that are the most fun to read.....
From the article:
" .....Any theory of time travel has to confront the devastating “grandfather paradox,” in which a traveler jumps back in time and kills his grandfather, which prevents his own existence, which then prevents the murder in the first place, and so on........"
Selected comments from readers:
- Someone’s mere presence in the past is sufficient to disrupt air currents, people, etc. so that the future is altered (even if imperceptibly) on an exponential scale depending on how far into the past one traveled. For time travel to the past to work, it would be a one way trip; one could never travel to the past and return to the same future from whence they came.

- Any physicist (e.g., Stephen Hawking, Kip Thorne, Michio Kaku, etc.) who claims that general relativity does not forbid time travel is a fucking crackpot or a liar/con artist.
Nothing can move in spacetime, goddammit. Furthermore, the idea that we are already traveling in time toward the future at one second per second is not even wrong. It is an illusion of the mind that we are traveling toward the future. There is no time dimension because a time dimension would make motion impossible. There is only the changing present, the NOW. That’s it.
All your time travel fantasies are crap. LOL.

Someone please go back in time and shoot sixwings’ grandfather.
- All the people who have ever gone back in time and shot their own grandfathers are already not here. The future is all done and in our past already.
- The question is — If time travel is possible, why hasn’t there been a scientist come tell his past self or other scientists that they’ve figured it out. He could help the process along. But then he wouldn’t need to if the process would be fast-tracked in the first place.
But then surely someone would have visited our time from the future by now if time travel is ever going to be possible??
- If you are going to travel back in time you already have. There is no way to change what has happened. You may go back with the intention of killing your grandfather or mine. You have already failed to do so, it is an inevitability. This takes away free will, turning us into mere chemical reactions going through phase changes as the universe cycles through.
