The first attempt to calculate gravity’s speed was made by Laplace, who redefined gravity as a field or a liquid. He calculated the speed to be at least 7 million times the speed of light. However, the finiteness of gravity’s velocity, irrespective of its exorbitance, posed a problem....
This is the speed of gravity as related to any mass m. For the Universe as a whole we have m = Mu and therefore vg ≈ c. There are about 1011 galaxies in the seeable Universe. Then gravity from a galaxy has a speed of about 3*105 c. There are about 1011 equivalent solar ...
Thoughts by Frank X. Didik. Can gravity by modulated? What is the speed of gravity? Does the half life and decay rate of elements vary? Does the speed of light vary? Science today is based on theory and speculation rather than hard facts. Op-Ed

What is the speed of gravity on Earth? What does the moon do for the Earth? If the mass of Uranus is 8.681 10 25 kg and the radius of Uranus is 2.556 10 7 m, what is the acceleration due to gravity on Uranus? What is the ratio of Jupiter s mass to the total mass of the Gal...
What is the speed of gravity on Earth? Gravity is measured by the acceleration it gives to free-falling objects. At Earth’s surface, the acceleration of gravity is about 9.8 meters per second. Q6 Does the influence of gravity extend out forever? The farther away you get from gravitational...
The first problem is that Earth is rotating at high speed. Earth's atmosphere and its oceans, rivers and lakes would be one of the first things to drift away into space. A lack of gravity would eventually destroy our very planet, writes Masters. " Earth itself would most likely break ...
“What is the speed of gravity?” It is only heard less often in the classroom because many teachers and most textbooks head off the question by hastily assuring students that gravitational waves propagate at the speed of light, leaving the firm impression, whether intended or not, that the ...

How fast do they travel across the universe? Gravitational waves travel at the speed of gravity! It is through the work of LIGO, Virgo, and observations from other astronomers that we learned that the speed of gravity is equal to the speed of light. Einstein predicted this, but our exciting...
