    Gravity Speed
AI Thread Summary
The discussion revolves around the speed of gravity, with participants humorously engaging in the topic. It is noted that the speed of gravity is slightly slower than the speed of light, which is approximately 186,400 miles per second. The conversation touches on the acceleration due to gravity, typically accepted as 9.81 m/s², although variations can occur based on altitude. One participant humorously mentions a fictional character, Mr. Robin Parsons, who supposedly adjusts gravity for fun. There is also a claim that gravity might be instantaneous, prompting further discussion. Overall, the thread combines scientific inquiry with light-hearted banter among participants.

hey all...does anyone know what the speed of gravity is?

OUCH! 186,400 miles/sec
Thats funny, I only started going 9 meters per second...per second...persecond...persecond...

PS I don't know of anyone who has actually achieved a measurement for gravity, itself, but we know it induces accelerations in matter and is probably in the lighspeed (+/- a little bit, maybe) range...

But do you like our sense(s) of humor?

if you must know it is slightly slower than the speed of light.

velocity = acceleration x time
No, actually, acceleration x time is the change in velocity, not the velocity itself.

True enough.
Where do you live by the way? 9.0824 \frac{m}{{sec}^2} is a bit low...

Mr. Robin Parsons is in charge of keeping gravity within tolerance everywhere. Sometimes he plays with the dials to create mischief.

SHHHHHH! (did you talk to Bad ***?)
 
i heard this somewhere that the speed of gravity is instantanious..
what are your thoughts on this. please forgive the spelling..lol

Sorry, it's been a long day. Is 32.174 ft/sec/sec ok? Do you like 9.8066 m/sec/sec better? I live on Shyne Road, first house on the left.
Well, normally g is taken to be 9.81 m/s^2. But you might find it to be 9.08 if you go on a high mountain or something, hence my question. :wink:
