you are actually answering slightly different questions one from a Newtonian perspective the other from a General relativity perspective.
In general relativity on the other hand gravity propagates at the speed of light; that is the motion of a massive object creates a distortion in the curvature of spacetime that moves outward at light speed.
but remember that general relativity is conceptually very different from newtonian gravity so a direct comparison is not so simple.
Strictly speaking gravity is not a force in general relativity and a description in terms of speed and direction can be tricky.
In that case one finds that the force in GR is not quite central it does not point directly towards the source of the gravitational field
and general relativity very nearly reproduces the newtonian result. In the case of a disappearing sun (whatever that even really means;
it's hard to discuss physics problems when the heart of the question involves a word as grotesquely metaphysical and unclear as'poof
but during that 8 minutes it would be orbiting as normal in that it wouldn't'lag'behind the sun.*Another way of looking at your discrepancy is to remind you all that relativity does away with an ABSOLUTE frame of reference.
Sorry your understanding of orbital mechanics is flawed fundamentally. As DCRANNE correctly mentioned Earth would neither be accelerated nor de-accelerated (who or
and was defined by Newton). Only it would fly now in a straight line. The same goes for all satellites.
and speed (aka angular momentum) in relation to the only center of gravity the still have -which is earth. So all lower earth orbits would basically be undisturbed completely.
Oh yes and gravity*does*work at the speed of light you might check wikipedia on'gravity waves'.'Sorry JRHELGESON the only thing that was correct in your post was-most probably-your name.
Get back to physics 101: -Of course according to science the sun would never just disappear into nothing so his disappearing act would violate most conservation laws
and belongs to the realm of fantasy instead of science. So stating that all his gravitatory âÂ#Âoefieldã¢Â# would disappear instantly
1-The most accepted theory of gravity is Einsteinã¢Â#Â#s General relativity. It says that gravity moves at the speed of light
No tsunamis at all. lol at the understanding of physics soem people have...dissappearing sun is not impossible-imagine some unknown dimensional rift
Classical mechanics assumes physical interactions propagate at infinite speed. In general relativity which supersedes classic mechanics gravity travels in waves at the speed of light.
The speed of gravity has actually been measured experimentally not with pinpoint accuracy but within the ballpark of the speed of light.
and teach classical mechanics because it is a good approximation of how objects with low mass and speed behave
and very few high school students have the math skills to tackle relativity. However relativity is far a more accurate model of how objects in our universe behave.
The article is about the heat from the sun hypothetically disappearing. The last paragraph about the mass of the sun being affected is really the cause of all the confusion.
This and all the other argumentation about Newton and Einstein completely misses the point because the real and only issue is FOOD
and light from the sun in near-instantaneous fashion it's not hard to visualize something highly improbable yet entirely consistent with the laws of physics.

But until recently inventors lacked the aerodynamics expertise to turn diagrams into mechanical versions of something as quotidian as a fly or a bee.
Although insects and their relatives represent roughly 80 percent of the world s animal species ome 900000 known types he mechanics of their flight had long been an enigma.
And the stubby wings of bees and other insects lift far more weight than can be explained using conventional steady-state aerodynamics principles.
so that as it flapped he could analyze the fluid dynamics. At the University of California at Berkeley neurobiologist Michael Dickinson built a robotic fruit-fly wing that likewise mimicked a fly s natural motion
Working independently the researchers characterized the aerodynamics of flight with unprecedented specificity. Dickinson and electrical engineer Ron Fearing won a $2. 5-million DARPA grant in 1998 to apply these principles to a fly-size robot.
which aerodynamics insights the students should try to reproduce. Flies have really complex wing trajectories.
other researchers have used flapping-wing dynamics to reduce the size of aerial vehicles capable of carrying payloads.

But within milliseconds the fly s center of gravity appeared to pull the fly back into a stable position.
