Re: Gravitational waves provide dose of reality about extra dimensions
#2So, is that a strike against string theory's extra dimensions, or is it another type of extra dimension being ruled out?
Re: Gravitational waves provide dose of reality about extra dimensions
#3Are there particular theories of quantum mechanics or string theory that are now any less likely?
Or is this just confirming what everyone expected all along?

It is a strike against the idea that over long distances, the spherical shell of "expanding and thinning" gravity can go down faster than 1/r^2 (which would come about from A=pi*r^2, the area of a sphere in three dimensions), achieving that goal by slipping in to dimensions higher than three. However now we have found that gravitational waves are about as strong as we expect it looks like gravity isn't leaving the world of 3+1D.

Sphere's have surface area and volume. Neither of those quantities is given by the formula for the area of a circle. I’m not a physicist and can’t speak to the merits of the rest of your post but this error of yours makes me doubt your post's veracity. Did you make a mistake in your parenthetical remark? Maybe it edit if you have.

I assumed it was a reference to the surface area of a sphere - which is 4pir^2. The point would still hold.

Makes sense. That’s what I would have thought if not for the area of a sphere in three dimensions remark.

Area = surface area not volume.
Physicists tend to drop constant factors when they do calculations, I’ve noticed.
