I’d love to see the images but that site is cancer

Whoever is sending these asteroids is getting their bearings awfully close now!

They must be. Aren't they the only ones to launch astronauts from US soil since the shuttle? Also they are launching NASA astronauts under a NASA contract so it makes sense to count them.

I guess where the force that stops it gets applied. Imagine the core halting so the crust momentum causes it to slide of the mantle. Massive quakes.
Dark side would definitely get cold once everything settled, below freezing for sure, and sunny side roasted worse than any desert.
Only dusk / dawn zones would be habitable

No, mass causes gravity, centrifugal force reduces are weight slightly, so once everything settled, everything would weigh more

Poor kid on the trampoline. Interesting for someone mid bungee jump.

Is it just me or does it seem like this happens quite a bit?

Are you asking what the planet would eventually look like should it stop rotating over time, or are you asking what would happen if it suddenly stopped rotating?

I think they were just being comical. Try to identify humor as much as you can

Technically, the side of the moon facing us gets less sun, because sometimes the shadow of the Earth falls on it, but the shadow of the Earth never falls on the far side.

That model’s out of date decades ago. Newer modelings find that with enough water, which Earth has, the dayside would be lush, and the substellar point would be really, really wet jungle as the ascending air dumps all its moisture down. You can read for more details in this blog.

Tidally locked and not rotating are 2 different things. The Moon is tidally locked to the Earth so we only see one face. The Moon rotates once every 27 days and orbits us once every 27 days. Mercury is tidally locked to the Sun.
Pick up a ball and have it "orbit" a lightbulb at home. A solar day (noon to noon) should be a year.
"Dark side" of the moon is a misnomer. All sides receive the same amount of sunlight. It's just generally people automatically assume the far side is always dark, and movies don't help.

It looks a bit like your lens was dirty/dusty tbh.

We'd fall off, wouldn't we? Pretty sure we'd fall off.

Once again the alien carnival goer misses his chance to score by failing to win his date the giant stuffed teddy bear.

The Sun's absolute magnitude (how bright it would appear at a distance of 10 parsecs), is about +4.83, which means that out to around 30 light years, it appears as a fifth magnitude star or brighter. Although there are many factors to how bright stars appear while observing from Earth, the classic constellations were limited to around fifth magnitude, or brighter (magnitude is an inverse scale; smaller numbers are brighter). So, for at least all systems out to around 10-12 parsecs, the Sun is bright enough to be included in their constellations (if they used the same criteria as our ancients did when creating star groupings).
Here is a chart of around 130 star systems where the Sun would be likely to appear as a significant constellation star.
