This is just silly. If time travel were possible, it would have been invented already in the future and our world would be a very different place.

- arethuza 16y agoWhat about limited forms of time travel such as the one in the film Primer - where they have a device that does indeed allow travel through time but only back to the point where it was turned on and only at the normal rate (i.e. it takes an hour subjectively to go back an hour in time).
- bermanoid 16y agoIn the article under discussion, this is not what the authors are talking about: they're literally proposing a model under which every time you traverse the extra spatial dimension, you end up at an earlier point in time. So the reach of that communication would be, in theory, unlimited.
- hammock 16y agoHow do we know the world isn't already a different place and the future just decided not to tell us about it?
- jcl 16y agoThe article postulates that time-traveling communications can exist, via devices yet to be invented. Since we currently have no way of interpreting the backwards-flowing information, we would not see evidence of its invention today.
