For a moment I thought you are an Estonian, because we, too, call it a falling star. But our military service is still mandatory :(

We call it a falling star in English too (though “shooting star” is more common, at least in my experience).

I saw a big one in the evening during army bootcamp. For a second or two it was as bright as day. One of the guys says "wtf was that?" and another replied "it's a falling star" (literal term we use for shooting stars in our language). A third guy asks, "so why do stars fall?". Silence. I ventured, "uh, guys... stars don't fall. Stars are like the Sun, just really far away. What we saw was a meteor, a rock that flew t…

In Italian as well, "stella cadente".

I have never heard the term "falling star" before this thread.

Yeah, you have to make sure you put them in your pocket.

Save them for a Rainy Day. Never let it fade away

Why is the top suggestion on a science video like that an anti-vax rant?

Suggestions are personalised for what it thinks you’ll engage with (depending on how much it has profiled you - if you’re logged in, have watch history). The top suggestion for that video when I’m logged in is a video about architecture…

I am not logged it on YouTube (ever). So this is the "default" suggestion.

In case the link won't load for anyone else, there's a YouTube video on the page: https://www.youtube.com/watch?v=RfNdaYqVxR0

Youtube has a general problem that angry and hateful and infuriating content is naturally more engaging to the human brain even if you don't believe it. That's why Youtube will still recommend right wing hate content even if you actively watch straight up socialist propaganda. It's just a more effective strategy that any ML or AI recommendation system will inevitability fall to.

It's similar to how casino slots aren't actually any fun because you don't need any fun to trigger a gambling addict, so they are optimized for that outcome rather than optimized for fun. Except it's even worse because nearly everyone is susceptible to the effects of anger inducing content, it's just how our brain works.

I was riding my bike to the Longs Peak TH, outside RMNP at around 5:00am one winter - around 9,000' - clear sky. A streak just like this went across the sky. I figured it was either a roman candle or the start of WWIII. Neither turned out to be true. Good summit of Longs Peak, that day.

I was at the base camp of Challenger Point / Kit Carson Peak, laying out watching the sky after dinner. I saw something similar to this but a bit more green and it shot off sparkles like a firework as it burnt up. Did not make the summit the next day though!

Always amazing when these things happen when the sky is that crisp and clear, and you're alone!

And one has been caught on film (we think) https://www.universetoday.com/110963/norwegian-skydiver-almo... . There’s also a nice coffee table book about them: https://www.amazon.com/Search-Stardust-Micrometeorites-Terre...

Damn nearly getting cut in half by a meteor while skydiving!

"Ann Elizabeth Fowler Hodges...was an American woman known for being the first documented individual not only to be struck by a meteorite, but also to live through the encounter."

Yes, relatively speaking. First likely hit I found: "Meteors enter the atmosphere at speeds ranging from 11 km/sec...to 72 km/sec ... The wide range in meteoroid speeds is caused partly by the fact that the Earth itself is traveling at about 30 km/sec (67,000 mph) as it revolves around the sun. On the evening side, or trailing edge of the Earth, meteoroids must catch up to the earth’s atmosphere to cause a meteor, an…

The "relatively slow" 11 km/sec is still 39.600 km/h, or around Mach 30 (although that depends on air density and temperature), so still pretty fast I would say...

There's no authoritatively correct reference for what "slow" or "fast" should mean in extraterrestrial contexts, however, I think it makes sense to look at it like this:

Suppose you were watching a (CGI) movie or a video of a meteor hitting Earth, with the whole globe on screen.

The diameter of the Earth is almost 13,000 km. So a meteor(oid) going even 70 km/s is going to take 3 minutes to hit from one diameter away.

It should look like it's barely moving on a planetary scale.
