We propose a new model-independent measurement strategy for the propagation\nspeed of gravitational waves (GWs) based on strongly lensed GWs and their\nelectromagnetic (EM) counterparts. This can be done in two ways: by comparing\narrival times of GWs and their EM counterparts and by comparing...

What is the relation between gravity's own constants and the speed of gravitational waves? Our attempt to answer these fundamental questions takes us far and deep into the universe. 展开 关键词: Gravitational waves speed of waves electromagnetismgravitomagnetism ...
waves, just as variations of anelectromagnetic fieldtravel as waves. If the masses that are the source of a field change with time, they radiate energy as waves of curvature of the field. Gravitational waves were first directly detected by theLaser Interferometer Gravitational-Wave Observatory(LIGO...
Gravitational Waves represent a nearly unique instance of unfinished business in the history of modern physics. One of the slew of novel concepts which arose in the revolutionary period of the early 20th century, they retained their place in the new physics for nearly a century in the total abs...
Gravitational waves as dispersed arrows The argument was put forward by the prestigious astronomer Tom Van Flandern, who calculated the arrow’s speed to be 20 billion times the speed of light, which is fair to be perceived as instantaneous. However, Einstein in his General Theory of Relativity...
根据第一段“The universal speed limit of any kind of wave — whether electromagnetic or gravitational travelling through a vacuum has been known since Albert Einstein developed his theory of special relativity in 1905.(自1905年阿尔伯特·爱因斯坦提出狭义相对论以来,人们就知道任何一种波——无论是电磁...
However, in the world, the great majority of the physicists follow the General Relativity, which explains the gravity like the effect of the curvature of the spacetime in the movement of free fall of the bodies. But, simultaneously they agree that gravity as gravitational waves is a quantum ...
