超弦string

超弦理論string theory
String theory is arguably the most popular theory in theoretical physics; that is, it cannot be proven. The idea, is everything you see around you is made up of tiny strands of energy that vibrate at different frequencies.

超弦理論（string theory）可說是理論物理學當中最著名的理論；因為它無法證明。在此理論下，觸目所及的每樣東西，都只是由細小的幾『股』能量在不同的頻率下振動形成。
