• General Relativity; Quantum Gravity; String Theory and M-Theory.
  廣義相對論；量子引力；弦論和M-理論。
• I've got it! I finally reconciled the black hole information paradox with my theory of string-network condensates!
  我成功了！我終於用基於弦網冷凝物的理論，解除了黑洞的信息悖論！
• Thus, it is worthwhile to investigate the decay of scalar fields in the background of dilaton black hole being the stationary axisymmetric solution of the so-called low-energy string theory.
  由於穩態時空具有更普遍的性質，所以研究低能弦理論穩態軸對稱解的伸縮子時空中標量場的衰減行爲是非常有意義的。

權威例句

• What makes Dr Burgess's proposal unusual is that he went out on a limb and suggested that these energy-sapping, curled-up extra dimensions should be as big as a few microns across, gargantuan by string-theory standards.
  ECONOMIST: Cosmology
• One of the best explanations of why the universe is the way it is—so-called string theory—requires that the universe be, in fact, ten-dimensional.
  ECONOMIST: A matter of gravity
• The strings predicted by string theory are so small and convoluted that unwrapping them would require energies that have not existed since shortly after the Big Bang. (This is the main reason why string theory remains just a theory.) Dr Arkani-Hamed's loops, however, may be observable with existing equipment.
