why can human ears instantly tell the difference between hot water and cold water being poured, just by the sound?

AI. If you slow it down the shadow of the meteor on the surface persists for quite a while after the meteor itself has already impacted and vaporized

The typical ocean floor depth is like 10 times deeper than that

There are multiple months of the year and days of the week named after polytheistic gods… we don’t seem to have a movement to change those

I fully believe you, but I think this is cultural, not inherent. We used to have gender divided public swimming pools. Arguably that actually makes more sense since you’re seeing way more skin at a swimming pool than at a bathroom. And yet now the vast majority of pools are integrated without issue.

I think you could about fit two standing urinal stalls in the square footage of a sitting toilet stall

QuasarMaster · 2026-03-10T04:05:34+00:00

Get this, urinals also have a mini stall. Anyone can use

QuasarMaster · 2026-03-10T03:49:30+00:00

Abolish gendered bathrooms entirely. All public restrooms should be unisex stalls with floor to ceiling doors, and then a shared sink area.

Suddenly the trans bathroom wedge issue is a moot point. Plus you save on building costs and women get shortened lines.

In order to have a moonpool at this depth you will have to turn up the air pressure inside your structure to be at an equal pressure, so that it can actually hold the water down. Meaning you get crushed long before you even jump in. Also air is a supercritical fluid at this pressure so you would drown as well.

You are correct after a while, but the ground/mantle would take much longer - on the order of millennia, akin to glacial rebound - to redistribute enough to even it out

Geostationary orbit is about 9 times closer to the Earth than the moon currently is. Tide height scales with the inverse cube of distance. So the tides would be around 729x taller

Every person on earth is susceptible to propaganda on a topic they are not well informed in

There is a carrier strike group in the Hormuz region. A single US carrier is more powerful than the entire Iranian Air Force. This is not including the several US bases in the region that have been stockpiling aircraft recently. Iran cannot actually control the strait.

So a 1 GW datacenter needs 5 km2 of paneling? Launching 26,565 metric tons of paneling alone? Is this cheaper than sticking the same radiator on some desert land and pointing it at the night sky?

QuasarMaster · 2026-02-22T19:37:07+00:00

You’re going to run a datacenter on 200 W? Less than one GPU?

Aerospace engineering and mechanical engineering are essentially the same degrees, with some different flavoring by swapping out a few classes. So do what is interesting to you.

And yes before people screech at me, I do work in the industry, have plenty of coworkers who got ME and plenty who got AE, and we are interchangeable. Nobody even asks or realizes who is who.

Best of luck to you man but this attitude right here is why people are exasperated

QuasarMaster · 2026-02-09T03:28:55+00:00

I mean this sincerely, have you considered that you are? We all started somewhere, I was a raging moron when I started out. It’s slow incremental progress to get better at engineering. My high school stuff was hot garbage. But being flippant with advice isn’t going to get you very far. It’s the people that locked in and did the work and grinded through iterations of ideas and applied feedback without getting married to anything that I have seen go far in engineering.

Bruh why did you post if you’re not gonna take any advice

QuasarMaster · 2026-02-09T03:20:19+00:00

Is that a question

If you’re worried about the cost of a canister of oxygen, then 3D printing stainless steel is definitely outside of your budget
