maybe is what will happen, but he started looking at the oceans and realized there is this vast unexplored universeour planet that we know very little about. below scuba diving depth, we have submarines for military use. there are a few instrumental submarines -- experimental submarines. jonathan: it seems like such a limited number of these devices that provide us with a wealth of knowledge. four there are literally submarines i can go to the average depth of the ocean. exploration, there is not a lot of funding for it. i don't know why. space seems more compelling. has always per trade space as this romantic thing, and the ocean is this scary thing. it is a dangerous, formidable place. crushing pressures and claustrophobia. a lot of things people just don't feel comfortable getting inside of and going underwater. jonathan: who is this guy? why is he the one to lead the exploration into the deep? why do we trust this guy?/ josh: he would say it's because no one else is. nobody was doing it. each of those subs are run by a government for national purposes. there are a few subs, one-off building eng
