Brian Greene votes with his feet

Look Ma, no strings!

This is potentially very stringy material, and in fact has exciting consequences about direct observation.

If (h/Mcutoff) is a single power, in principle the satellite Planck will detect these types of fluctuations. If its a square law, no satellite will ever be able to see it. I like there approach, and I agree with the conclusiosn about the boundary conditions, everyone should be pleased b/c it actually sets up a falsifiable prediction.

The exact nature of what will be seen of course is beyond us, String theory and other qg methods as applicable to cosmology are to early in their development to make any sort of reliable guess about exact signatures. However the bulk oscillatory component in the CMB should (by most conservative guesstimates) exist at some scale.

It seems that Brian Greene is a proponent of the theory of string theory, which suggests that the fundamental building blocks of the universe are not particles, but tiny strings vibrating at different frequencies. He is demonstrating his belief in this theory by "voting with his feet," meaning that he is physically moving or taking action to support it.

The phrase "Look Ma, no strings!" is likely a play on words, as it is a common expression meaning to do something without any hidden or underlying motives or agendas. In this context, it could mean that Greene is fully committed to string theory and is not influenced by any external factors or biases.

Overall, it seems that Greene is confident in his support for string theory and is not afraid to show it. His actions speak louder than words, and he is willing to stand by his beliefs and theories.
