Introduction: The major event that gravitation wave is discovered to be universe of exploration of a mankind, so of gravitation wave how much is delivering rate?

Gravitation wave is discovered to be a heart-stirring good news. But with respect to the object between the action speed of gravitation, still want to explain again. Newton thinks the gravitation between the object is delivered do not need time, exceed namely spur action. I object, above paragraphic in also had said.

Gravitation wave has been confirmed now, although say not all wave,move with velocity of light. For instance Shui Bo, sound wave, because the earth is a special existence,this is. Nonexistent sound wave is in vacuum. Gravitation wave is the concept below cosmic measure, according to the theory of Einstein, gravitation wave moves according to velocity of light necessarily. This bit I am approve of, what be early in front is paragraphic in had had discuss.

At the same time I explained, because gravitation wave is delivered with velocity of light,be, fall in astronomy measure so, the abrupt change of cosmic star cluster, can make be apart from its very remote galaxy, either have gravitation effect with it immediately. This universe star cluster is like this moment lost a pulling force, can accelerate collapse to shrink! Now the data of observation is the universe is expanding, but because have gravitation effect,be in fact, just make expand have " alleviate. " if there is action of this kind of gravitation between galaxy, so of the universe expand speed, be more than present observation data far certainly.

Lift a simple example: again? Wu of rare ? reef says razor clam of closely question She wood ah Long? rice, the time of action of gravitation of two person happening is 1 divide with rice of C=299 792 458 of velocity of light / the time that second earning goes to, this time is 3.333e-9 second, 1/100000000 what be equivalent to one second, this is the time that the mankind cannot feel at all, also be the mankind the atomic Zhong Ye of highest science and technology is at present accurate without method.

But if a person appears suddenly on the sun now, the time that needs 8 minutes according to reaching the earth from the sun solely so, the gravitation action contact that shows this person that appears suddenly on you and sun also must use 8 minutes. But his quality is small, from you far, according to gravitation theorem so formula can know, you do not feel his gravitation effect to you at all. You two people are located to oneself the gravitation action of the heavenly body feels apparent.

The friend that has top news for instance asks, the earth is round, why doesn't that person have drop out earth? Because,be gravitation.

Extend again, if your head hole is opened, may think of any object or person, his all round the heavenly body that has countless, namely this countless heavenly bodies have gravitation effect to you. Is the gravitation action that that one person gets infinity? ?

Be such, a person can say get the gravitation action of two hundred and seventy-six million four hundred and forty-seven thousand two hundred and thirty-two heavenly bodies, but gravitation won't infinity. Everybody did not forget, force has resultant force. The force that experts on four sides adds up how much join forces is. Very simple, go to school of physics of our high school passes. You can drive block with the force of 5N right, but another individual towards the left also is used on block with the master piece of 5N. Block was not moved. It is because of the join forces of two people 0.

And more than be you all round have effect of material of countless heavenly bodies at you, the someone else all round you, other object faces similar case. So cosmic system of whole is " stability is even perhaps " system.

The god is very so wonderful still. The action of gravitation, effect of close to leaving it still great quality object is big. Like bringing muscularity with respect to what be like a person to basically accept the world, other and moonish ball, because the sun is apart from far, the gravitational force that get is small. Same earth compares the sun to the gravitation of the moon big to the gravitation of the moon. Because be apart from a problem,also be.

Emphasize again finally a bit, the speed of gravitation action is velocity of light. Not be Newton exceeds with what Ma He thinks spur action.

Somebody can ask the likelihood more: Why cannot be to exceed spur action? ! Apparent, if the connection between two objects does not need time, also do not need medium, also do not need to be apart from. So time did not have a meaning, so now is the gravitation wave of observation how to return a responsibility? Everything of modern physics should weigh model. This is very absurd!
