Warts and all: The Earth as seen by the GRACE satellites. The red spots represent places where the Earth's gravity is unusually strong. The blue ones are where it's weak. Image: NASA/University of Texas Center for Space ResearchNews flash -- water has weight. I wonder what weighs more, rock or water?
This is true...but the differences in gravity across various areas amounts to about a 1 ounce difference in the weight of a 150 pound person. It’s not as if it’s anything even remotely noticable.
What weighs more...a pound of water, a pound of feathers, or a pound of rocks??

[snip] Earth’s spin warps space around the planet, according to a new study that confirms a key prediction of Einstein’s general theory of relativity. After 11 years of watching the movements of two Earth-orbiting satellites, researchers found each is dragged by about 6 feet (2 meters) every year because the very fabric of space is twisted by our whirling world... The effect is called frame dragging. It is a modification to the simpler aspects of gravity set out by Newton. Working from Einstein’s relativity theory, Austrian physicists Joseph Lense and Hans Thirring predicted frame dragging in 1918. (It is also known as the Lense-Thirring effect.)...Any object with mass warps the space-time around it, in much the same way as a heavy object deforms a stretched elastic sheet, explained study leader Ignazio Ciufolini of the Universita di Lecce in Italy. If the object spins, another distortion is introduced... If the space around Earth is being frame-dragged, then satellites ought to be caught up in the deformation... Ciufolini’s team analyzed millions of laser signals bounced off two satellites, called LAGEOS and LAGEOS 2. Both are highly reflective spheres not designed to do any work of their own. They look like 2-foot-diameter (0.6m) golf balls and contain no batteries or electronics. The researchers say their result is 99 percent of the predicted drag, with an error of up to 10 percent.

So...I’ll have a much better chance of dunking in a pickup basketball game on a freighter in the Indian Ocean? ;)
Most rock (not counting pumice) is denser than water. Hence, it does not float.
Well, let's throw a rock into a pool of water, then throw water in a pool of rock...
Does this say that the world is obese?
I’m so confused now
The Great Global Obesity Epidemic?
I’ll watch NBC tonight and really find out/s
You post the coolest stuff.
“Some of these are signs of global warming.”
Stopped reading right there because there is of course no way to prove this. I have no patience with these people anymore.
