Is it normal to dive to the bottom of the marianas trench?
the other day, i was on a boat, and the tour guide said that we were passing over the Marianas trench. The guy next to me said that it was a fun place to free dive, and i thought he was joshing, because I had heard that it was the deepest ocean trench on earth and if you dove to the bottom of it your lungs could burst. nonetheless, i dove to the bottom in about an hour, and came back up without any trouble at all. It got a little dark at about fifty thousand feet, but the luminescent creatures lit everything up enough for me. is this normal? have any of you also tried this? is the marianas trench a great free diving destination i haven't heard about yet? please tell me soon.
