This is not the same method at all and this is much more reliable. For King Tut, they used ground penetration radar, which is very hard to interpret. Here: (1) this is confirmed by 3 independent teams using 3 different detection technologies, (2) we used the same statistical criteria as for discoveries in particle physics (deviation 5 sigma from the model).

In addition, we clearly see the new void on Nagoya's data (Fig.2).

Unfortunately, cosmic-ray muons cannot be used in King Tut tomb because we can only see "above us" (the muons come from the sky).

I'm definitely looking forward to where this research takes us. I'm curious if there have been any efforts to create a muon-like transmitter that would add more flexibility to the sensor system. Is there something about muons that prohibits this?

This would basically require a LHC-like particle accelerator.

However, we can acquire data for more time (depending on the detector technology), which will give us more statistics.

On a tangent, but as has been asked here, does this disprove Jean-Pierre Houdin theory?
