I'm disagreeing that it's trivial to check for fusion because of low mass of gas inside the bubbles and suggesting that it's unlikely that fusion would ever happen in a bubble because temperatures required for fusion are way higher than bubble cavitation temperatures.
Do you have any ideas on how detection can be made in a bubble radius of say 100um?
In laser fusion experiments the pellet size is in mm range and it's completely filled with solid/liquid hydrogen to achive high particle density.Thats not possible in a bubble.
The thing is even for something as well studied as sonoluminescence there is no scientific consensus. Literature is all over the place when it comes to bubble gas temperature during cavitation.
Lots of arguments and debates are ongoing in the community. I think that's what happened with fusion story.
> However it's quite possible that I'm wrong. Because bubble science keeps on throwing new surprises.
Ultimately that's my assertion. No need for exaggerated/optimistic claims when something interesting turns up about it on a regular basis.
