The three-brane, photons and the Higgs field.

[Daecon]

Something I was wondering about after reading Brian Greene's "Fabric of the Cosmos" book.

 

He says that if the Universe is a three-brane, why haven't we noticed? Because the three-brane is completely transparent to electromagnetic radiation, which is the only thing we canuse to detect the Universe around us (Photons being open strings that are forever stuck, attached to this three-brane).

 

Something made me think... The Higgs field creates mass in everything except for the photon (and something else if I remember correctly - the gluon?)

 

Maybe it's the same kind of effect, but manifested in different ways.

 

What I mean is that could the three-brane be made out of the Higgs field itself?

 

Because EM radiation is transparent to it, it isn't able to aquire mass and can therefore travel at light speed, being both unnoticed by the Higgs field and the Three-Brane of our Universe.

 

I think I'm starting to rant now, so I'll stop typing.

It is not so much that the three-bran is transparent to the photon - it is that the photon is constrained to always lie on the brane. So it cannot interact with anything not on the three-brane and thus we only see the brane and nothing else.

either that or string theory doesn't work and is a pile of nonsense.

 

sorry for the oppinion, but I don't see much in a theory that attempts to unify all of the forces without understanding what all of them are (gravity).
