GSFC's Terra mission detects indisputable evdence for gravity waves.
Ok, this was inspired by last month's Physics Today, but y'all remember that "gravity waves" are old fashioned fluid waves with gravity as the restoring force, and quite distinct from gravitational waves.
Those will come later.

First, what is a gravitational wave?
I find it interesting that some people are expressing difficulty in understanding what a gravitational wave is, as though everybody (who is not a physicist) has a perfectly good understanding of what any kind of wave is. We don't need to go too deeply beneath…
Remember the GRAIL mission? At the beginning of the year, two satellites, named Ebb and Flow, arrived at the Moon and fell into a parallel orbit. There is an instrument on board that very precisely determines the distance between the two space craft, said to be about the size of a typical washing…

Einstein, the brilliant mind behind general relativity and the concept of "spacetime," is making the news again this week. As you all know, gravity isn't some mysterious…
It's that time again - yes, we have yet another wacko reinvention of physics that pretends to have math on its side. This time, it's "The Electro-Magnetic Radiation Pressure Gravity Theory", by "Engineer Xavier Borg". (Yes, he signs all of his papers that way - it's always with the title "Engineer…
