Karis   11 #25 Posted February 26, 2012 Gravity can be measured very easily karis, as long as you are at the place you want to measure. We can't remotely measure it though (well actually we can, but indirectly)  Which is EXACTLY what I said.  I mean, exactly! Share this post Link to post Share on other sites Share this content via...
Jabberwocky   45 #26 Posted February 26, 2012 Ok if gravity travels at the speed of light and an object appears then we`d start moving towards it as soon as we saw it because the speed of light allows us to see it at the same time as gravity reaches us...  Im resisting the urge to google this. I want to hear opinions, google is killing the forum because people are expected to use that instead of actually communicating here.

Karis   11 #27 Posted February 26, 2012 That is a brilliant question.  I've no idea:D  From what we know (and consider that we're still on theoretical grounds here) it would instantaneously affect the universe around it. Share this post Link to post Share on other sites Share this content via...

Jabberwocky   45 #29 Posted February 26, 2012 A black hole is formed by a collapsing star, they don't just appear.  Yep I know, I was speaking metophorically. Trying to imagine what would happen if a huge mass of gravity were to appear out of nowhere. I was trying to sort of quantify it to get it into perspective.

Deltic   10 #30 Posted February 26, 2012 Id rather not if you dont mind...? I prefer to hear peoples opinions on the matter. Google is too easy. If I wanted to google it I would have, just as I google other things such as coughporn  Sorry about that the thread title misled me into thinking you wanted facts or information rather than speculation., my bad.

Faster then light then? If a vast mass appeared a light year away would we be dragged towards it before we saw it...? Share this post Link to post Share on other sites Share this content via...

HeadingNorth   11 #34 Posted February 26, 2012 Ok if gravity travels at the speed of light and an object appears then we`d start moving towards it as soon as we saw it because the speed of light allows us to see it at the same time as gravity reaches us...  That is correct (assuming the current hypotheses are correct.)  Similarly, if the Sun were to spontaneously vanish, it would be about eight and a half minutes before we saw it disappear, and we would be freed of its gravitational pull at precisely the same time.
