"SCIENCE isn't the biggest barrier to time travel, it would just be way to
[sic] expensive to build the time machine, an Australian physicist says."

Bummer. The public never understand economic problems.

I'd be surprised if time travel in any shape or form (including sending
information to the past/future) would be possible. I've once heard some
idiotic theory that it would only be possible to travel to a point in time
after a time machine was invented. If you think about it that's totally
stupid since it merely depends on your frame of reference. Aliens may have
invented time travel before us still allowing the 'Grandfather paradox' to
take place.

I've argued many times that we won't be able to know for sure if time travel
(or FTL travel) will be possible until we have a complete understanding of
the laws of physics, which we don't at the moment.
