Abstract

In 1880, Albert Michelson conceived the idea of optically measuring the speed of earth through the solar system. However, the Michelson-Morley experiment conducted for detecting the expected motion of earth, gave null result. Einstein propounded his theory of Relativity on the assumption that speed of light is isotropic in ECI reference frame. The Relativity model can be invalidated through an unambiguous physical experiment that confirms anisotropy of light speed in ECI reference frame. Let us consider a 3 km long line segment AB, fixed on surface of earth. The proposed experiment for measuring absolute velocity of earth involves sending a picoseconds Laser pulse from location A at time T₀ and detecting it at location B at time T₁ to measure the time of flight T_ab of the laser pulse from A to B. On the other hand, by sending a picoseconds Laser pulse from location B at time T₀ and detecting it at location A at time T₂ we can measure the time of flight T_ba from B to A. For accurate measurement of times of flight T_ab and T_ba the precision atomic clocks located at A and B must be in absolute synchronization. The absolute velocity U_ab will be given by U_ab/c = (T_ab - T_ba)/(T_ab + T_ba). Final absolute velocity U of earth can be computed from pulse flight timing record of 24 hours. For this we need to use the latest cutting-edge technology in Atomic Clocks, Pulsed Lasers, Ultrafast Detectors and Picosecond Time Interval Counters.
