of course it has. every subatomic particle has a corresponding antipartcle. a neutron's the antiparticle is known as antineutron

so why neutron and antineutron is different?neutron has no charge.

very basically, string theory says that electrons and quarks are made up of 1dimensional "strings". hence string theory.

There is an antiparticle of the neutrino, called the antineutron. An antiparticle is not just defined by having an opposite charge, but its quantum numbers will also be opposite. In the case of a neutron it has a positive baryon quantum number (that is it is equal to +1), but its antiparticle will have a negative baryon number (i.e. 1). As mentioned above, every particle has an antiparticle, but in some cases such as photons, these antiparticles will be identical to its particle.

String theory,if correct,describes physics at an energy scale far higher that we are able to probe directly.if we could probe the energy scales that string theroy describes directly,then we would presumably see the various exotic things like ExtraDimensions,DBranes,Dualities and soo on..this exotic physics underlies the world we experience (assuming string theory is correct).but string theory is separated from our experience of the worldnot by centuries of time,but by a similarly vast gulf in energy scales.particle accelerators would have to be a hundred trillion times more powerful than the ones going into operation today to reach the range of energies where we think extradimensions open up and stringy effects could be observed directly.
