'Mach c'? Scientists observe sound traveling faster than the speed of light

For the first time, scientists have experimentally demonstrated that sound pulses can travel at velocities faster than the speed of light, c. William Robertson’s team from Middle Tennessee State University also showed that the group velocity of sound waves can become infinite, and even negative.

velocity of sound waves can become infinite, and even negative.

velocity becoming negative is arriving before sent

the sound pulses travelled through the non material field (dimension) at faster than light speed velocity (superluminal).

the observer, within the speed of light field (dimension), observed the sound arrive before sent because the observer detected the sound at superluminal velocity quicker than their senses/technology could hear/detect via light speed transmission

the two you`s

I realized what happened and look back and I'm standing on the sidewalk just still, with my eyes open and then "me" looked at "me"...

As soon as I make eye contact with myself…I get that head rush again like I’m going feet over head and I’m back in my body with my heart beating so fast it was all I could physically hear after the giant crunch of getting back in body

i believe you placed your personality (conscious you) into the non material field where time is like this:

A femtosecond is the SI unit of time equal to 10-15 of a second. That is one quadrillionth, or one millionth of one billionth of a second. For context, a femtosecond is to a second, what a second is to about 31.7 million years.

the sound is like the sound barrier but of the transition between non material and material realm

i think your description of experience is quite beautiful

thank you for shareing
