The problem with geosynchronous orbit is that you need to be at a high altitude to maintain it. That increases the packet round trip time to a receiver on the ground. Starlink satellites orbit low enough to give a theoretical 20ms ping. A geostationary satellite would be at best 500ms. It’s fine for some tasks but lousy for applications that need low latency, like video calling.

In the past 6 months, Starlink satellites made 50,000 collision avoidance maneuvers. They now maneuver 275 times a day to avoid crashing into other space objects.

They use an on board AI to calculate the positions, but each time they course-correct, it throws off forecasting accuracy for several days. So a collision isn't an if, it's a when, and suddenly we're in Kessler Syndrome territory. Or maybe enough people will eventually wake up and realize Musk was an actual idiot all along.

But until then, great, low pings for video calls. Hurray.

This is completely factually inaccurate. 2 minutes on Google will help you learn but seeing as how you’ve been spewing crap all over this thread I don’t think it’s worth my time to even bother helping you understand.

Can you debunk it for the rest of us?

Shortest answer is that even if all Starlink satellites suddently exploded at the same time for no reason, they'd fall back to Earth in a matter of weeks. They're waaaay lower than the other satellites you're thinking of (see discussion on geo-stationary satellites for why), so they need to be actively pushed every few days just to stay up. They're so low they're still subject to atmospheric drag.

Search the web for “star link Kessler syndrome”. It’s well documented. It’s also discussed elsewhere in this thread.
