Unresolved mistery: What is the speed of Gravity?

I can't even fathom what a gravitational wave truly is . Does it move faster than light ?

There is no gravity...

However there is density & buoyancy.

I would think it acts like water.so it only react's the speed of the objects that disturbed the gravity.

The only available resources that I can think of we could use would be how the moon's gravity affects the ocean tides. If you could measure the start of the depression of the ocean at a point and then the moment light reflecting off the moon hits the same point, you might be able to get a close idea of the speed of gravity; if there is such a thing. I would think of gravity as a field that could be considered an object. The larger the field the stronger the gravity, it is not a moving object but a force that affects matter in an area around an object that expands and contracts depending on it's strength.

always thought it was 9.80 m/sec2

oh shut the fuck up. try and find the southern cross in the northern hemisphere

the speed of gravity would be the exact same as electrical current. It is not a question of how long but how large.

that's acceleration due to gravity. op is talking about how fast the effects of gravity propagate

Einstein assumed that gravity moved at the speed of light.

Newton though gravity to be instantaneous.

Einstein was much closer to correct as infinite speed has been ruled out and there have been measurements showing that gravitational waves propagate near c.

It's equivalent to the speed of light because gravity IS darkLight
299,792,458 meters per sec

There is a lab: The Laser Interferometer Gravitational-Wave Observatory (LIGO), exclusively devoted to detect gravity waves from outer space, working since 2011.

They measure the loss of mass throug loss of energy in neutron stars' orbits, wich decays. The decrease in orbital speed can be detected from Earth.

BUT it is an indirect measurement, and is based on observations from data that comes at Earth at the speed of light.

Hence, the speed of gravitational waves is not measured. They only have proven its existance.

Gravitational waves are very small forces, but is believed that development in this field could conduct to new ways to travel in space with a spacecraft, in the future.

No formal theory has yet been developed. Only empirical measurements.

Just my own theory here, but I think gravity is faster than the speed of light. If the sun were to blink out of existence, I don't believe that we would be held in orbit for the next few minutes until the speed of light caught up and all the planets just started following their un-gravity controlled trajectories. Imagine a rubber band breaking, but with an instantaneous effect.
I only imagine this theory because gravity is stronger than the speed of light; so; why couldn't it be faster? And since it can be faster, how can we properly measure it since we don't have the tech yet?

Would measuring gravitational waves be the same thing as measuring the propagation of a body's gravitational force upon another?

I think we may have two different things here.

gravity is fake

I don't believe that such a thing as darklight exists. Gravity is one of the four forces assumed to exists at macro and microspace.

And yet many scientist doubt there is such a force. Newton only found a way to describe movements in the solar system on an EUCLIDIAN space. This means, using x,y,z linear coordinates.

The Universe can't be explained unless it's assumed that lies on a non-Euclidian space (everything is non-linear).

variable ,adjusted for relativety to masses around it.
robo school of physics!

I think also that gravity, if exists, is instantaneous force.

I think of gravity as an infinite tissue that bonds matter.
Everything is connected to everything at every dimension. If samething changes, this is propagated through the tissue at once, at infinite speed.

Think gravity fields as a WEB that entangles everything.

Gravity is not a speed to be measured ..it is an assumed force. A force created by mass, composition and density.

It is a force so powerful at times it can bend spacetime, thus it cant be measured as a speed IMHO

A force that can even overpower the speed of light.

Maybe, in the future, instruments can be created to measure the speed of influence of the Moon movements on ocean tides.

I think this would need very complex models, to decople relative speeds of rotation and traveling around the Sun from the real force of the gravity itself. Hard stuff.

By now, Newton theories suffice for most of Earth and Solar System mechanics.

I didn't mean gravity as a force, but the speed at wich gravity propagates: gravitational waves, scientists say.

According to Einstein, everythin CEASES to exist at the speed of light.

Matter is infinite, and time stop flowin. Everything freezes.

Example, at the door of a black hole.

It's relative.

We measure from the sun by the time sunspots energy hits earth.

There is no gravity. It's all electromagnetism. All matter, in different states of magnetism ranging between coherent (a magnet) and diffuse. ( the molecules in your body all slightly pulling toward earth center)

Gravity is a hoax. It's been for years.

Good one. I agree.

Then, we can't measure distances of 10000 years light and assume c=constant. What if our concept of TIME is applied in a wrong way and time CONTRACTS at big distances??

Maybe celestial bodies are closer and are younger than what we were told they were.

Fake science is astrophysics?

An echo of an event...poorly understood yet unique

Scientists can't explain what forces make a common refrigerator magnet to work. Are you really going to let them convince you that they've got the Universe figured out?
