One possible reason, among a few, that #OceanGate submarine lost communications and hasn’t been located is something that messes with how sound travels through water, #thermoclines. They can act as blocks or conduits for sound. Caused by differences in water density. Water density changes because of temperature and salinity, mainly. When a sound encounters these changes in density it can be reflected so something below it won’t be heard by something on top. They can also form a conduit where sound bounces between two layers.

Imagine being trapped in something the size of a minivan. Imagine it is pitch black. The air is thick because you and 4 others have been breathing the same air for hours. You are trapped under 15,000 feet of water. It’s cold because there is no power. Condensation everywhere… You can get up and move around because of the cramped space and even if you could it would just use more oxygen which you have a limited supply of on hand. No contact with the outside. Every now and again you hear the creaking of the hull caused by the tremendous pressure.

#OceanGate missing submarine is a sad situation and I pray it works out and everyone is found safe. Here is the thing. The submarine is a joke. The ballast system requires shifting of people to jettison used pipes. Wtf? It is a tragedy waiting to happen. It isn’t a game. I spent 11.5 years in the Navy and was sub qualified. Ocean Gate submarine is nothing more than a play toy for people with too much money and not enough commonsense ! Underwater, especially at the depths most military submarines operate isn’t a place to play…

#Racism doesn’t go away because laws are past. #Racism can only be defeated by education and people wanting to change. The #CivilRightsAct didn’t end racism, it just made it harder for people to discriminate against people based on #Race. It wasn’t a foolproof remedy… #Hate and #Racism still exist but they are not as obvious as before, at least not for most people. #Racism is just evil and it likes to hide in the darkness. What does it do? It pools together until it becomes strong enough to be a threat. Like roaches breeding or rats.
