So light travels at the speed of gravity?

Thats what they just said in the video. Didn't you hear?

i think its the other way around.

I can explain ... ( 6 months ago by Etimespace)

I can explain gravity with out drawing force. With out bending space.
I can explain old light redshifting with out expanding space. I can explain galaxies twirling with out dark matter.
I can told how atoms nucleus energy expanding all a time.
You cant told how space expanding. I think that space dont expanding at all. I think there is no extra dimension at all.
Old time people believe stardome and you believe extradimension. Lets forget extra dimensions!

Gravity is simply ... ( 4 months ago by kmarinas86)

Gravity is simply an effect of the conservation of angular momentum. Why does gravity exist? Because objects move the way they do in ways that conserve angular momentum.
Why does light bend around graviting objects twice as much as predicted by Newton? Light cannot produce torque on a distant body, whereas a mass bearing object can. Since angular momentum must be conserved, light therefore bends twice as much as Newton predicted with his gravitational constant.

is the suns gravity ... ( 4 months ago by farerse)

is the suns gravity pulling earth nearer the sun as the years goes by ? or is the orbit /gravity curve a fixed state ?

The suns gravity is ... ( 4 months ago by kmarinas86)

The suns gravity is indeed pulling earth nearer the sun as the years go by. This affects the rotation of the earth and the sun respectively.
A similar thing is happening between the earth and the moon. However, the moon is actually receding from the earth.
The former is due primarily to gravitational waves (angular momentum from sun-earth to gravity waves) and the latter is primarily due to tidal friction (angular momentum from earth's rotation to moon's orbit).

thanks for reply . so we are melting slowly ?

Hold on there a ... ( 4 months ago by kmarinas86)

Hold on there a second... I don't recall us "melting" slowly. What do you mean by this?
My best guess is that you mean that if gravitating objects are emitting quantities of angular momentum due to gravitational waves and tidal friction, that the same might apply to smaller bodies, such as ourselves. Then the answer would be yes, we would be "melting" very slowly.

nah i meant a more simpler thing :) that we are getting closer to the sun , and the suns heat will get more intense.

Array ( 3 months ago by sandrobrox)

A simple question:
If the sun warps space-time in our system, is it then faster to travel 1 km within the space between the Sun and Mercury than within the space between Neptune and Pluto?
