It's not exactly the wrong place to post something about Kessler syndrome, but it's obnoxious to post a video link instead of explaining the idea and/or linking to a written source.

Looking up Kessler syndrome online, the "2 days away" thing seems to mean that satellites have maneuvering thrusters to avoid collisions with each other. If a big enough solar flare knocked out all the collision avoidance stuff in the satellites, then within 2 days (3 days is what the other source said) there could potentially be enough collisions to trigger the syndrome.

Anyway people launching stuff are now at least aware of the issue and taking some kinds of precautions, maybe not enough.

And may not be
