量子引力可能导致光速的能量依赖性。伽马射线源的高能辐射可以用来限制这种效应。我们发现，从蟹状星云脉冲星的发射能量超过2 GeV的落后，在70 - 100兆电子伏的不超过0.35毫秒（95%的信心），并放置在1：8 - 10 - 15 GeV的光速量子引力效应的能量尺度上的下限。在不久的将来，通过观察蟹状星云在更高能量（50 - 100 GeV）下的脉动，这一界限可能会提高两个数量级。
Quantum gravity may lead to an energy dependence in the speed of light. The high energy radiation from gamma-ray pulsars can be used to place limits on such effects. We find that emission from the Crab pulsar at energies above 2 GeV trails that at 70-100 MeV by no more than 0.35 ms (95% confidence) and place a lower bound on the energy scale of quantum gravitational effects on the speed of light of 1:8 10 15 GeV. This bound might be improved by two orders of magnitude by observation of pulsations from the Crab at higher energies, 50-100 GeV, in the near future.
