However, the space-time distortion caused by gravitational waves is very small. For example, when GW150914 reaches the earth, the strain is only 10-21. LIGO is an L-shaped modified Michelson interferometer, and its structure is shown in Figure 1. Two 4 km long interference arms are perpendicular to each other, and the arm length change produced…

Researchers develop new laser pointer detector
Recently, a group of international researchers developed a new instrument for the laser pointer Interference Gravitational Wave Observatory (LIGO), which can remove quantum noise and expand the detector’s detection range in the universe. This new device called “quantum vacuum squeezer” helped LIGO reduce this confusing quantum crack phenomenon and expand the detection range of the detector by…
