From the article:
Whoa! That's a lot of ergs! Nice summary article but I'de like to see some info on how the energy output is calculated to be that high since the masses might be large but still finite.
Different strengths I can understand; based on mass. But since we haven't yet any confirmed detection of "gravity waves", how (does anyone know) that they will or can vary in wavelength? Are we considering that gravity waves will have a "spectrum" as with EM radiation?
