Documentaries on Discovery Channel

Hi everybody! I would like to ask you two things. Some months ago i watched some documentaries on Discovery Channel but i don't remember the title! I can only remember that they was talking about p-brame theory and that some physicists wasn't able to describe it! And in anther they were talking about three physicists on a train that invent (i think) a new theory of physics.
Maybe it was "Through the Wormhole", but i don't really know...
Can anybody help me? Thanks.

Oh, I saw that, it's what I call a screamer. I remember the physicists on a train. It's about Hollographic universe. It had Brian Greene saying a black hole was like a wallet and that all of the data of anything that enters the blackhole is kept as information in 2D on the event horizon. Some nonsense about we might be the edge of a blackhole. Well, if information about what goes into a blackhole is stripped off and held on the event horizon, doesn't that mean that the information had to exist at the time it went in? You'd have to watch it to hear what I am referring to. Of course my memory of how bad it was could be tempered by how much I disliked it.

If this isn't the one, I'll keep looking.

Such TV programs are discussed here often, ALWAYS with the conclusion that there is a LOT of bad science in them. They have VERY pretty graphics and are entertaining to watch, but should NOT be taken seriously. TV "science" is not real science, it is dumbed-down pseudo-science, and often just plain WRONG "science".

Do not be fooled by the fact that some of the people shown are reputable scientists (more or less) ... it seems to be in their contract for these TV shows that they HAVE to get stuff wrong.
 
Yes i know i know but i would like to know the name of that three physicists of "the train"...

In english, p-brane sounds like "pea-brain" which is an old insult. (As in, "your brain is as small as a pea")

"p" stands for the number of dimensions, but why choose that letter in particular? It may have been a slight sense of humor on the physicists part. If not, it's still been making some people giggle ever since.

I think you're talking about Neil Turok and that other p-brain, sorry, p-brane that developed that cosmology model with the colliding thingamagigs that keep restarting the big bangs. :tongue:

Watch this four part series from NOVA and you will forget all about the one you can't remember.
