Sound is transferred through a medium literally as a wave. When you get right down to the core of it, the wave requires movement within the medium to transmit.

So it might help to conceptualize it not as “Liquid cannot move faster than the speed of sound in it’s medium” but more like “The speed of sound in a liquid medium is defined by the speed at which energy can propagate in that system, which includes motion.”

Are some options for people who don’t want clothing that is skintight and revealing.

I’ve very occasionally seen brands like this at box stores. But the vast majority of time if you want something that isn’t skin tight you have to get shorts designed for men and some sort of sports top with a shirt.

Yes. Baggy clothing isn’t optimal for swimming, and trunks will tend to stick awkwardly anyway, but a lot of guys would feel uncomfortable if speedoes were the only option. I know I would.

It’s a double standard plain and simple.

The blue and yellow maps are flipped because they are on opposite sides.

The green parts are where opposite sides line up (through the center).

The “two” Antarcticas aren’t on opposite sides of the same globe, the Antarctica (blue) lines up with the opposite (yellow) northern Greenland (overlap in green). Just like the blue Greenland mainly overlaps the yellow Antarctica showing green.

Just find a spot on the blue map, and then look at the yellow map to see what’s on the opposite side (it looks reversed since you are seeing that other map from below.)

“But, when I talk to people in general, most seem to not worry because they “have nothing to hide”, and most are only worried about their passwords, banking apps and not much else.”

Sounds like they have passwords and banking apps to hide, You should demand their bank account and credit card details to verify that they have made no illicit actions.

If they point out that they have no reason to trust you with that information, that’s when you point out that police, government, or corporate groups are made out of people just like yourself. They might have some codes of conduct, or a vetting process, but it just takes one person malicious or careless enough for you to be severely impacted.
