[...] It’s an interesting result– how important it really is for understanding high-temperature superconductivity, it’s hard for me to say, but it merited publication in Science, so it’s pretty significant. Does it demonstrate the physical reality of string theory? My take on that is pretty similar to something Sean wrote a while back: [...]

interesting, fact is they did one in haifa and didn’t have hawking radiation, neither evaporated, and it was done only with 10.000 atoms in
bosonic state. now they are going to mass strong force quarks at cern
hundreds of thousands. If they become a boson, their strong force, 100
times stronger than the electroweak force at haifa, will create a sucking hole 100^3 times faster in its absorbition. Speed of sound x 100^3=speed
of light. Thus a quark hole is actually a black hole and will be created
at cern and will not evaporate.
interesting haifa has proved that a boson quark hole will be a black hole
and it will not evaporate and it will be made at cern
interesting nobody has thought of this at cern?

"Of course there is no problem in having something go faster than sound, but sound waves themselves are stuck with that speed limit." hmmm... "Of course there is no problem in having something go faster than light but light waves themselves are stuck with that speed limit." Might we hope?

Is this really, truly, an example of sound science?

In order to actually read the post, I had to wait for a Templeton Foundation ad to get out of the way. Folk wisdom has often noted that he who pays the piper calls the tune.

I think that the proper analogue for black hole would be “silent hole.” It’s not that it’s not speaking, it’s that it can’t be heard.

“Anechoic hole” is what I’d call it.

Brian, It is fairly easy to produce one of these in a Fox News studio. We need to place a nozzle in the studio and then suck air out of the studio a super sonic speed. As air approaches the nozzle it will accelerate past the speed of sound. The place where the flow becomes super sonic is the horizon of the anechoic hole (dumb hole, whatever). As long as the commentator is within the horizon, the desired affect will be achieved.

Of course, that is just the theory. It still needs experimental verification. I hope you can find funding to do this valuable research.

how do we get one of these dumb holes into Fox New’s studio?

Does the interior geometry of a Mute Hole form a Cone of Silence as it collapses towards an acoustic Singularity?

Had to chuck in that reference. But as for ‘ether’ there was a “Scientific American” article about the prospects for acoustic black-holes and how they might imply an ‘ether’ for space-time structure after all. But it won’t be a 19th Century style ether – it’ll respect Lorentz invariance for starters.
