God's getting ready, brewing up the inferno to blast the Earth with another another Carrington event (but bigger) and knock down the new Tower of Babel.
Hope you guys own a modern physical encyclopedia.- 1

Lots of solar activity fucking with Earth right now, maybe it was a satellite knocked out of orbit?

Not sure if it was an anomaly or intentional, but it was certainly the Starlink they were expecting to see. Just in more pieces than they expected.

We are in the middle of the first major cycle of solar activity since the beginning of the mass commercial satellite age essentially.

'Runaway' black hole the size of 20 million suns caught speeding through space with a trail of newborn stars behind it
Astronomers have discovered a "runaway" black hole, potentially the first observational evidence that supermassive black holes can be ejected from their host galaxies.

The James Webb Space Telescope discovers enormous distant galaxies that should not exist
Giant, mature galaxies seem to have filled the universe shortly after the Big Bang, and astronomers are puzzled.
Early galaxies found that are may have older than expected stars in them.

After rereading this claim of mine I questioned myself. So I looked up some stats.
Ten years ago there were a little over 1,000 satellites in space. Now there's a little over 7,000. And you have people like Musk sending them up who are likely cutting corners (Starlink is about a robust network, not individual robust satellites, y'know?). As this current period of heightened solar activity continues (the sun has 11-year cycles remember) expect to see more shenanigans with commercial satellites failing.
Note that it's already been a "stronger" cycle than predicted.
Hopefully nothing like this happens again:

The comforting thing about Starlink satellites is that they have a ~5 year orbital lifespan. So if a massive disaster happened creating a Kessler syndrome that made those low earth orbit altitudes a nightmare, I think ? it'd work itself out in a few years. Then again I don't know what kind of velocities would be imparted from the collision that might boost the orbital lifespan. It's intuitive to think that any collisions would decrease the orbital lifespan of the mass, but I don't know.After rereading this claim of mine I questioned myself. So I looked up some stats.

I do think humans will have to go through at least one massive disaster causing a Kessler syndrome before there is enough political weight to prevent future events.

Depends on the nature of the collision, but in general you're right. If something manages to come up from behind you from roughly along your same trajectory, it will increase your angular momentum. Such collisions would be the exception tho.

Yeah, agreed. I don't know how common it is for high earth orbit satellites to have ellipictal orbits that intersect with Starlink, but if they did that orbital mass could displace into high earth orbit if a starlink keppler syndrome btfo'd anything that descended into LEO with enough velocity to exit LEO.
Starlink satellites are about 550km altitude and high earth orbit are at 42,000km. I think it's ok.

I had to ponder about it a bit more but also debris cast off from explosions, either from midair collisions or electromagnetic radiation causing fatal power supply malfunctions, could end up colliding with other objects and even boost their altitude.

The Everyday Astronaut guy from YouTube was just on Lex Fridman's podcast and he said that the Kessler Syndrome would make the low earth orbit altitudes unusable for 5-10 years but it would eventually clear out but GPS and geosynchronous satellites wouldn't be affected.
