No Future?

Here's an update on the MIT time travelers's bash.
Example
It didn't go so well. "Unfortunately, we had no confirmed time travelers visit us," the organizers said. "We may be doing a run of t-shirts if there's enough interest."
That leaves us with a disconcerting question. Maybe no time travelers arrived from the future because there will be no future. Maybe something really bad happens before we learn to shake the shackles of spacetime.
Which forces us to take solace in John Titor, the only self-indentified time traveler from the future to be living on Earth right now. He claims that he came back from 2036, using a time machine built by General Electric. If he's right, rejoice and start saving up for your time-traveling retirement cruise. Here's how you do it. Buy some GE stock. Now!

But surely the boffins of MIT have realised the simplist fact of time travel in a multi-verse...

The great thing about the multi-verse theory is that the grandmother paradox would not be a paradox because new universes are being made all ...er...the time, so to speak. So going back to kill granny would not result in a paradox because any number of universes in which you did not kill granny would still exist.

The problem MIT seems to have missed is that it's a question of navigation...going back in time is as opaque as going forward. The real nut to crack will be how to navigate effectively to a particular universe, one in which MIT have posed this challenge....and from a universe in which this challenge also existed within. Now if MIT makes a better job of publicity in ...the future...maybe then...

...in fact if MIT could get every person on the planest to make the following utterance - 'Time Travellers Welcome' then maybe they could send out an effective enough ripple through enough universes that they might raise MIT’s chances of both (A) being remembered for the event and (B) being remembered for it in a universe that would spawn a time travelling system...that works in both that universal tree and amid the branches of the ones we flittered through yesterday...or will tomorrow.

Not unlike the search for life...searching more of the sky to increase the chance of contact.

Bood, it would be extremely difficult to break out of our spacetime and get lost in some parallel universe. Doing so, you would certainly violate some physical law, like the law of conservation of energy. I believe that the easiest way to travel in time is backwards, following your own worldline.
