I saw the special on the Discovery channel a couple years ago. Looks
interesting.
One can "look" back in time. Look at the moon... you
see it as it was 1.3 seconds ago. We look back in time
with our telescope to study the history of the universe.
Give the current understanding of the way the universe
works, one cannot "travel" into the past.

Relativistic travel into "the future" is permitted, but
improbable.
Relativistic travel into the future is just another bullshit
path relativity leads the clueless on.
:)
Time travel itself, is complete utter bullshit, and nothing
more than such.

It's clock stopped.
Someone might like my article, "An Essay on Time" posted on www.Helium.com
and also on
http//groups.google.com/group/oscillatorsubstance-theory. I think it
does a fairly good job of debunking any notion of time travel.

You can always hope someone might like it.
Discovery Channel hosts many type of programs, some address reality
("How Things Are Made"), and some focus on the paranormal. Frankly,
I've had my fill of their evidently never ending series about Alaskan
Crab fishing!
Their series "Dirty Jobs" is generally excellent, but many of their
offering rate (at least in my book) a definite 'Yuck'!

Hi original (ring laser, slow light) time travel paper made an
elementary mistake (it used c both to mean c the constant of
proportionality that relates space and time units and c the speed of
his slowed laser) which would disgrace an intelligent 15 year old. I
am surprised his paper survived peer review. There was (and is) no way
that idea will work, and that is the idea that was widely touted.
Obviously you appear to be able to do interesting things if you are
allowed to have weird mass-energy distributions but its not clear
whether you can get them. Bear in mind that the Godel solution to GR
has lots of closed timelike loops which doesn't sound very physical
does it? But yet its an exact solution.

I see one big problem.
Lets say he does get this thing to work and he has a conversation with a
future version of himself. This "future self" sends him a ZIP file
containing documents concerning research done decades into the future. He
now has the documents and has no need to do the research. Where did the
information come from?
Anyone that hallucinates there is a constant of proportionality relating
independent space and time units would disgrace an intelligent 15 year old.
