I was reading up a bit about string theory, and the author (Brian Greene) mentioned that the strings are "2-dimensional". How can something be 2-dimensional without being infinitely thin? Given the technology was available, wouldn't it have some width?

It's Quantum field theory that puts a constant on everything, making the universe 2D is easier to deal with. That's done by setting Newton's universal gravitational constant to 0. If you are writing plan, is easier to do it flat, and build on that. The human mind finds it a little hard to conceive 3D problems and solutions!

 

String theory only says that the string is 2D as the plan is not complete enough to add the gravitational constant.

 

So your right, but it's easier to pretend that the world is flat, as we are not at the stage to set sail to prove it isn't. Metaphorically speaking.

blike ur a dumbass obviously nothing is 2D. You need to learn to think as i must put in kindergarden terms for you "OUTSIDE THE BOX". Im very disappointed in you son

Actually, realizing that some things are in fact 2-D requires thinking outside the box you're sure not capable of

 

 

ex: cosmic strings
