Speed of gravity faster than light?

I would love to know if this could be possible also I remember in my youth riding a pedal cycle at night seemed to be easier than riding in daylight & sound seems to travel further when it's dark; is this just imaginable or maybe light does slow things down slightly? And if gravitity is faster than light can we somehow store it for space tr avel?...us.2u

that site is just pseudoscience. the first paragraph of the home page basically says modern astronomy/cosmology is crap.

Less background noise, less wind/turbulence generally.

and colder air, again generally.

Haven't you ever heard of the space-time continuum? Einstein solved all this nearly a century ago with his theory of special relativity.

Thanks for your insight Yourdadonapogas I believed they had something there; that gravity might be faster than light; can we measure the speed of gravity? Can we create it? as to making spaceflight? How do we define gravity & light as I believe there seems to be no volume, or mass but do they have energy? & can it be measured? Also when there is abscence of light is the gravitational force weaker or do we just imagine this?... us.2u

can we measure the speed of gravity?

 

Yes. It's been discussed in another thread.

In trems of terminal velociy, gravity could be "faster" so to speak. Gravity's terminal velocity depends on the amount of mass a subject has, such as pen on your desk, it's terminal velocity is nearly zero, and the earths is seven f/s, and a black holes is greater than the speed of light(2.988 x 10^9 m/s I think correct me if i'm wrong)

Thanks crzykllrghst do you think eventually gravity could be stored to propel a mass object? I don't know how this might work but does it sound feasible for future travel in space? maybe gyro-scopically controlled by use of magnetism & gravity like our first flying saucer? Or does this seem outrageous?...us.2u

For the times, it seems outrageous, but I dont know what the future my hold for travel.

How are you defining "terminal velocity?"

[crzykllrghst]

How are you defining "terminal velocity?"

the maxmium speed of an object in a vacuum caused by gravity's "pull"

omg, haha, i had a thread EXACTLY like this, but only about 2 people posted in it and it died... anyways.

 

 

----------------i editted this post, please read the posts i made after this-----------------

[ydoaPs]

links or at least a description of the experments that "proved" the speed of gravity to that of c?

[KholdStunner]

ok, ill try and find one. i remember reading about it a year or so ago, and then seeing it on the discovery channel (haha, what a great source )

 

ill post it if i can find it.

this link shows how the gravity could be faster than the speed of light: http://www.ldolphin.org/vanFlandern/gravityspeed.html'>http://www.ldolphin.org/vanFlandern/gravityspeed.html

 

heres another link:

http://www.ldolphin.org/vanFlandern/

 

heres a link about people talking about how people found out that they r the same speed, and they are also posing new, unanswered questions:

after doing some research, i found out i shouldnt have used the word 'proved'. but i have found the approximate speed of light which is 2.99792 x 108 meters per second, this relates VERY closesly to the speed of light.

 

 

 

heres the experiemnt with a brief description:

It's in the other thread that I mentioned; there is a search function available. It's cryptically called How fast is gravity?

van Flandern does not represent the mainstream of physics. Sturgeon's Law (90% of everything is crud) is especially relevant to the internet's plethora of "I don't believe relativity" population.

Why does a pen sitting on a desk have a terminal velocity of zero? Why do you think it's mass dependent?

If it was an adult bull elephant it would fall through the desk?
