MIT + Time Travel + Convetion

[Alex Pelan]

Just occurred to me...if, in the event that someone does time travel back to this convention, won't they immediately change the future, thus destroying their existence?

If thats true then we will never know will we.....

In some theories. One way to look at it is that all time travelling events ever to happen have already happened, and thusly the future will already have been written accordingly.

Or we could opt for the BttF thoery in which in our dimension, only a discrete number of timejumpers actually game, and in any scenario with other timejumpers will be played out in an alternate dimension (ala BttF II)

since the universe is expanding and our solar system is hurtling through space at thousands of miles per hour

wouldnt a time traveller also need a star ship? you send yourself even one hour into the future, and the earth will no longer be at this location when you pop back in

someone travelling from hundreds or thousands of years in the future would need to travel light years to get back to where we are now, relative to the center of the universe.

still the idea of only having one time travel convention is a little presumptuous - why not have one every 100 years?

I can see people in the future saying "you wanna goto that 2005 convention?"

"nah, the weather was miserable, besides theres nothing to do in Boston in 2005 - lets goto the 2805 one next"

Who says time is relative to position? Everyone knows a good time machine would compensate for that kind of thing anyway.

Time is the fourth dimension. If you want to meet me you have to specify X,Y,Z coordinates plus time coordinates. Im not going to stand on the corner of 5th and Main for eternity waiting for you.

since the earth is travelling through space at an incredible speed, if you travel through time and somehow manage to stay attached to the earth, isnt there a time-travel-rate at which you would be travelling faster than light?

Einstein would be very upset with you! c is the limit. Its not just a good idea, its the law!

If you could somehow attach yourself to the earth, then wouldnt you need to exist in all the times between now and the time you were heading to?

If I travel from today back to last year, wouldnt an observer in normal time perceive me as a frozen statue, sitting in my time machine, in the same location, from last year until now?

A good time machine, as mentioned above, will be invented in the future that will over come that distance, likely by antimatter travel.

Remember, the world was flat til Galileo said it wasn't.

With c, space is the limit!
