I was scrolling comments to see if i am the only one who thought about him

Yeah I guess, but that doesn't really help. Humans already killed most of the whales so rubbing in our technological superiority is quite gauche.

You never know if whales are going to get revenge for this kind of stuff someday 😅

Unless the nuclear war and global warming kill off 99.999% of us, making our infrastructure unsustainable, then our mating call goes back down to a fraction of a kilometer. Whales: 1, humans: 0.

As sound travels through a water layer where the speed through which it travels varies with depth, the sound will tend to refract towards where it is the slowest.

A layer where temperature decreases as depth increases will refract sound downwards. A layer that has the inverse temperature properties will do the opposite. A layer that is isothermal (where the temperature remains constant as depth changes), will still tend to refract sound upwards because the increase in pressure also increases velocity, although not as strongly as temperature does, which is why temperature differences can easily overcome this effect where the water is not isothermal.

If you have a layer that refracts sound downwards on top of a layer that refracts sound upwards, you just created a sound channel, which acts as a wave guide in which sound will remain trapped and travel far longer distances horizontally before dissipating.

Ultimately you can't really put a number on the required temperature differences because there are many other factors to take into account like how steeply the speed of sound changes, how tall the layer(s) are, what is the frequency of the sound, or how much of it you want to remain "trapped" in the sound channel.

"The SOFAR channel (short for sound fixing and ranging channel) ... is a horizontal layer of water in the ocean at which depth the speed of sound is at its minimum" ...
"The SOFAR channel acts as a waveguide for sound, and low frequency sound waves within the channel may travel thousands of miles before dissipating." ... https://en.m.wikipedia.org/wiki/SOFAR_channel

I bet he'd hate bears, if he were to switch fields.

If someone outside of your match radius matches with you, you actually still will be shown their card, so, if you really want to game the app, you set your radius to .1 or whatever, and then only match with people outside it, because those are guaranteed matches. By doing this, you make your Like to Match ratio skyrocket, which causes Tinder's algorithm to put you at the front of the list, and gets you even more matches
