rKeep in mind that these are the only four parameters that are allowable in Newtonian gravitation. You can perform all sorts of calculations from this force law to derive, for example, elliptical planetary orbits around the Sun. But the equations only work if the gravitational force is instantaneous.... [+]
This would make orbits not only elliptical, but unstable. On the scale of a mere century, orbits would shift substantially. By 1805, Laplace had used observations of the Moon to demonstrate that the speed of Newtonian gravity must be 7 million times greater than the speed of light. Modern constraints are now 20 billion times the speed of light, which is great for Newton. But all of this placed a great burden on Einstein....
qualitatively, it isn't merely a sheet of fabric but all of space itself gets curved by the presence and properties of the matter and energy within the Universe. Note that spacetime can only be described if we include not only the position of the massive object, but where that mass is located throughout time. Both instantaneous location and the past history of where that object was located determine the forces experienced by objects moving through the Universe.
So that's the theoretical motivation for why the speed of gravity should equal the speed of light. If you want planetary orbits to be consistent with what we've seen, and to be consistent for all observers, you need a speed of gravity that equals, and to have your theory be relativistically invariant. There's another caveat, however. In General Relativity, the cancellation between the gravitational aberration and the velocity-dependent term is almost exact, but not quite.

WOW ! 😮 If the gravitational speed = the speed of light and precise, does this affect the rotation speed of the Planets? Are core rotation speeds equalized?

Fantastic article. Great read. Thanks 🙏🏻
I feel like this story is holding me down 🤔😂
May be 'The String Theory' is a probable answer to the quandrum of gravity verses light. Though theory is attracting less attention however, it does resolve space time matrix before the Big Bang and give answers to unification of four forces of nature i.e. missing gravity link
Not now, science. We are busy with rudimentary virology.
Gravity is really difficult to understand. All the theories sound like: God said, gravity attracts. Then gravity attracts, but, how, why?
It would be an unimaginable coincidence if two constants of nature were exactly the same. That they are in the case of gravity & light leads to the question, 'Are light & gravity the same?' Impossible? No, they're probably both merely 'aspects' of an underlying carrier.
there is no gravity.
Better hold that gravity bong
My eyes crossed reading this
Here's the thing, general relatively is said to completely fall apart near ultra dense objects of near unfathomable mass (blackholes), also within a year or so there was an observed mass particle ejection from a blackhole that seemed to break the speed of light
Fascinating, good read.
No these are two different variables that have realistic applications
Whelp, this caused me to ask the question if gravity bend light. Apparently, it does. Now I must dig deeper. Does gravity slow light? Or does it just cause it to travel further than if it were to travel as a crow flies.
ZenModeTrading I will politely disagree.
I have questions.
What we call 'gravity' is what we can perceive as waves, but we don't know yet what 'gravity' actually is. It is possible that this concept is at the origin of the creation of time and space and then it cannot have 'speed'!

💕 Lovely
It’s late Forbes, go to bed.
Bookmarking. Way too late to read that.
Surely energy and mass must be part of that equation?
The speed of gravity does not equal the speed of light that's an idiotic statement to start a premis on.
“Shut up” I said to me, when my mind said, “It’s so difficult.”
You know you’re Forbes right?

Dear Forbes. I have been tremendously impressed by your writing on physics and cosmology. Please keep up the good work. It says a lot about the quality of the rest of your work Kudos

There are 2 types of waves Think tennis net ● You could pluck a thread & send a fast wave of vibrations throughout the net. ● Or give the whole net a slow sine wave shake like shaking sand from a beach towel. But it is a 3-D net, and compression wave.
... and ?
Nice Theory. Not like the crp they teach in ** studies.
🤯
Typical newton classics, don’t think this may be fundamentally right . The sun exerts gravity not because it gives light but because it warps space time so if the sun was to go dark , light may take it’s due time but gravity would still be maintained due to the space time warp .
Screw that crap... I'm looking for travel at the speed of thought.
You're really overthinking gravity. We are actually stuck in 5th dimensional being's bellybutton. It's so sweaty and cavernous that we keep sliding back in. The being has no need for a shirt, so we can't escape with lint. Some eon the being will shower and we'll be free and clean
causality is limited by the speed of light. we still don't really know if gravity travels at all. That would require some actual evidence that gravity is a force instead of a tertiary effect of entanglement (information density problem).
HA! Neeeerds!
Quick opinion before reading article yet. “ nothing can travel faster than speed of light”
Hello amazing famz checkout this lovely jam it’s lit and nice feel the vibe don’t miss out love y’all 🔥🔥❤️❤️
The speed of gravity=the speed of light
NEEEERRRRDS
It is that, we wouldn't understand when our planet have a straight motion (as sun collapsed or may be go into a black hole) because as we will see the first blackness, at the same moment we have also detached contact from Sun- Earth elliptical system. 😀😀

Gravity is one thing that we still need to figure out especially when there are ships that Bob Lazar describes that run on an artificial gravity system to be able to go through space-time. Hopefully soon we can figure out what gravity truly is and use it to our advantage as well.
nice article
I Fucking love science (it's on Facebook) a channel. Splains Stuff
Sounds about right elonmusk ?
So if the sun just vanished - all the planets would continue to orbit a non existent star; Mercury for 3.2 minuets Venus 6.0 Earth 8.3 Mars 12.6 Jupiter 43.2 Saturn 79.3 Uranus 159.6 Neptune 4.1 hours Pluto 5.5 hours
Mind. Blown.

Lol false. Which dimension of light do you speak of? 😉
JennySnowBoscol Refreshing read first thing in the morning. All in balance, all as it should be.
And in simple, Time is the opposite/opposing force. Time & Light are linked, Gravity is opposite.
And in simple, Time is the opposite/opposing force.
I would never had thought the speed of gravity would equal the speed of light, but it makes intuitive sense.

Wrong although it’s close very very close, speed of light and speed of gravity even time each hold their own grounds on a separate chart “factors of opposition on the frequency spectrum,
Warped light
Why can't Speed of Gravity just worry about itself and leave Speed of Light alone? Ask on behalf of EmoPhilips
THIS is something that should be reviewed weekly.
Time to stop fitting facts to Einstein's theory. The article contains a huge amount of manipulation and controversial statements.
So the speed of gravity is 299 792 458 m / s Thats trippy
If sun disappeared, light & vibrations would stop in 8 min. Gravity 'field' - actually quantum thread network would take much longer to renormalize Light is vibrations in network Network itself is a substance (medium). It cannot dissipate at speed of light
I'm really high and need to read this again tomorrow, but this either sounds wrong and only relative to our sun, or proof that gravity is less about pull towards and object and more about push from dark energy
Great explanation and very interesting
I'm sitting on the couch eating generic yodels I have no shot at understanding this regardless of how much you dumb it down

Forbes found this out in 2020
The disrespect to Physics on the title.
This isn’t news.
That just sounds wrong 🤨🤨🤨🤨
But is it faster than the speed of love?
But gravity is acceleration and not speed..
speed of gravity
duh.
This was an incredible read. I wish more understood that we’re literally hitchhikers in the galaxy. At one moment, I thought: holy shit, we’re literally riding a wave a gravity around and through the galaxy. Blew my mind. Loved it. More!

This is incredible. More articles like this please.
What does SPEED of gravity mean?
G waves r from the motion of mass through space, velocity dependent, 2 black holes orbiting r producing continuous G waves from their velocities & upon merger the waves should cease, the merger itself not producing waves & yet they find 1 wave at merger. Explain That please

Ouch 🤕 😷
A bit old news, like few dacades old..
Interesting remarks Ethan, the rest mass of a gravitational wave must be zero is an interesting pondering... What is mass if not a space time deformation? What is a gravity wave, if not the same, just moving? What is rest mass if not the mass measured...in the same inertial frame

lgmedina_
....because the weak field approximation of general relativity that models gravitational waves has a propagation speed that is the speed of light?
nope
cotocolengoo
Я знала это
I’m almost certain this insight will be used to create a new weapon of mass destruction.
The problem is gravity think its speed will surpass light; and will pull anything to show it.
😎
Shake a mass and the change in the gravitational field — the gravitational wave — propagates at that same speed. “So the fact that the speed of gravitational waves is equal to the speed of electromagnetic waves is simply because they both travel at the speed of information,'.

Exciting article, must hang tight though but we'll explained!
That's how Pucci's stand, Made in Heaven is too op
great illustrations 🤪
There's no such thing as gravitational speed... Gravity is not a mass itself... Gravity is caused by mass... And speed is always associated with mass - otherwise speed of my thoughts is even greater than the seed of light.. What a misleading article it is..

you should stick with fashion and political commentary
While the 'speed' of gravity is true, there's error in quantifying it. To summarize: Gravitational waves from the Sun will travel to us at light speed. But a vanishing Sun would instantly have Earth traveling out of its orbital path.

Rubberbandits re Birmingham
The speed of light isn't a constant and gravity acts on objects at great distance instantly (hence the whole orbit thing)... Try again
That's why the speed of light and the speed of gravity equals to the speed of space-time
Those wobbles are fast , , bet we could surf on them if we really tried.

Funny, but no. Strength vs speed.
Who at Forbes is trying to be me?
Gravity does not exist and thus it does not have a speed.
I said this years ago. It’s because gravity IS light.
Drd r
Not now Forbes.
If star trek was right gravity does affect the flow or time. Oooooohhhh
Is there an explanation for the 1.7 seconds difference?
Forbes isn’t only about big money ! ..
Gravity has never been proven to exist.
More evidence God is real. As if we need more evidence. Hebrews 11 By faith we understand that the universe was formed at God’s command, so that what is seen was not made out of what was visible.
