How Fast Is Gravity?

Recommended Posts

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!

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.

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.

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.

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.

Instantaneously? Faster then light then? If a vast mass appeared a light year away would we be dragged towards it before we saw it...?

Have you been working on that world domination plan again:suspect:

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.

Opinions! Thats 99% of the forum! Google is a short cut thats useless for opinions.

 

Just think how small the forum would be if everyone and everything was directed to google.

What does light have to do with anything?

 

You've been watching too much Star Trek
