rollcage Posted February 1, 2007 Share Posted February 1, 2007 For the past couple days at school, my friends and I have been discussing this: How fast does gravity travel? If the sun suddenly disappeared, would the earth fly into space at a tangent to its orbit the instant the sun disappeared, or would it be 8.3(-ish) minutes before we noticed? Remember, Einstein stated that nothing can travel faster than the speed of light, but could gravity be an exception? Or does the force of gravity travels slower than the speed of light? There has been a lot of debate on this subject, here's the first two sites I found in case you're interested: http://en.wikipedia.org/wiki/Speed_of_gravity http://www.space.com/scienceastronomy/grav...eed_030107.html Link to comment Share on other sites More sharing options...
DiaboliK Posted February 1, 2007 Share Posted February 1, 2007 all depends on the gravity i guess. each planet has a different gravity depending on its core's elemental makeup and the size of the planet. it been awhile since ive delved into physics but my main target was nuclear physics and sub-atomic particles....

Soündless Posted February 1, 2007 Share Posted February 1, 2007 gravity itself doesn't move. the speed all depends on how big the object is being attracted. -ithink, that makes sense to me Link to comment Share on other sites More sharing options...
