string theory?

Question

If we make powerful microscopes in future, can we see strings or not? are there in 3-D world or 6-D?

Answer 1

Unlikely. String theory is falling out of favor as an explanation of how the universe hangs together.

Answer 2

Probably not. Strings (if they exist) are about the Planck length, which is far smaller than anything our equipment can 'see.'

Are they in a 3-D world or a 6-D? Well, neither. According to most models I've seen, 11 dimensions are required for the theory to work, seven more than the visible three spatial and one perceptible time dimension.

Answer 3

Never say never about what we may be able to do in the future. Right now it looks unlikely that we will ever actually see the strings of string theory.

If they exist they are probably in an 11 dimension world which is pretty much impossible to even imagine in our 4 (counting time as 1) dimensional outlook.

Answer 4

you will never be able to 'see' strings. strings are MUCH MUCH smaller than photons. in order so see something, you have to bounce photons off of it. if you tried, you would destroy the location of the string and would never be able to see it. one day maybe, we can observe them. big difference.

as to what some have answered, i dont think string theory (m theory) is falling out of favor at all. it is just that when a theory exists that claims to be the theory of everything, it is expected that that will be challenged by a lot of people. also, technologically we are far away from ever proving it so some think it is a waste of time (not me)

Answer 5

string theory is just a theory don't worry about it becaues by the time you are taking about it wont be there.
