Fast Radio Bursts (FRBs) are the brightest (Tb ~10³⁷K, which is higher than the Planck temperature) radio transients (~1 ms) in the Universe with unknown origin. Such bright point sources with coherent emission can be used to probe space-time at the source and along the path through the gravitational and plasma lensing. In this talk, I will discuss a direct measurement of the Lorentz factor in the giant pulse of the Crab pulsar and the implication for FRBs’ energies.
