The speed of sound in air is ~340 m/s, in water ~1,430 m/s, and in steel ~5920 m/s.
Damn auto-correct.
The first time I heard it I was stunned just how loud it was.
Can you imagine being a sound deadening-engineer designing subs? Thats some impressive capability.
Recall the pic of the sub that collided with a (chinese) sub:
I'm not one to deep dive into sub design, but that looks like a lot of sound damping material to me...
I also watch anything and everything I can about subs, and the unofficial story was a chinese collision... A man can dream...
They claim it was a previously unmapped under-water land mass and the cover story was that it could have grown from the crust since the last time we mapped there....
This was in the south china sea correct? and we have seismic sensors everywhere, a lot in that region due to Indonesia's propensity to quake... (My brother is a COlonel - I don't take the official story regarding the military - and especially subs...
We haven’t come anywhere near mapping the entire ocean, and seamounts can pop up quite quickly. https://www.smithsonianmag.com/smart-news/underwater-eruptio...
> In 2018, seismometers around the world detected mysterious rumbles emanating from a usually quiet area in the Indian Ocean between Comoros and Madagascar. At the time, researchers were astonished to find a 2,690-foot-tall underwater volcano, which is about 1.5 times the height of the One World Trade Center in New York.
As with most conspiracy theories, this one falls apart on even casual examination.
