The String Theory-and im new

[ninja nemesi$]

hi-im new here.....im 15, from london, and i like physics...lots! lol

String Theory
i found this site that has a whole load of info about it, and even 3 one hour clips explaining it and the theory behind it-

apparantly, all particles are made up of little strings that vibrate, and that's how energy is made...these strings are so small, that in comparison to an atom, they would be the size of a tree, where the atom would be the size of the universe....!

here's the site-

sorry if this has already been discussed....im still new-and 15-lol

Top of the forum on Strings.

No worries, though. It's the thought that counts! Welcome to the forums.

And hey, what's wrong with being 15?

lol----i dont particularly see myself as a geek of any sort, but usually when i tell people that im 15 and im into astrophysics.....lol-u know [6)] hehe

thanx for the link [:)]

Blah, the prejudices we're subjected to.

What's the difference between being 15 and wanting to be an astronaut and being 15 and being into astrophysics? One of 'em actually knows what he's doing!

Unfortunately, there are no testable predictions of string theory, so it is premature to say that particles are actually strings. (On the other hand, supersymmetry, which is a major player in our untested theories, *may* be discovered in the next 3-5 years.) Anyway, string theory has a great depth and richness like a forest with a hidden finely tuned and interconnected ecological system...the problem is we get lost in the forest a lot. There is enough beauty and strange things going on in the theories we *have* tested and which therefore *do* describe fundamental ways in which the universe works... like the Standard Model of particle physics (which by the way, only takes on its full beauty when you learn the framework of quantum fields, unfortunately!). Speaking from far down the road: the journey to get to these things is well worth the effort.
cheers.

can someone explain supersymmetry to me please?
