pineapple comments on China builds world’s first 20GW microwave weapon that can fire a 60-second burst

There is an issue with that, if the starlink saterlites were destroyed they would no longer be able to make avoidance menovers. This could very quickly lead to a cascade of massive crashes that pretty much means we will never be able to leave the earth for a long time.

Not true. Starlink are in a very low orbit and regularly (1 or 2 a day) will simply burn up themselves as they fall out of orbit.

Which is also fucking horrible. Yeah just further pollute the atmosphere with vaporized satellites why don't you. Hope that Fortnite battle was worth it.

that will decimate the ozone layer in 15-30 years.

🤦
I always thought of de-orbiting just to burn-off as a waste, but now this.

The researchers suspect this would help shrink the ozone hole that forms over the South Pole every year,

Ok, so there seems to be a silver lining.
A lesser Ozone hole during a certain period.

Now just to know if the Ozone decimation is winning over this little phenomenon.
Either way, the LEO satellites seem to be to big a mess for their worth, unless you are just considering their military worth.

A cascade of satellite collisions is called Kessler syndrome and the risk of it happening is rapidly increasing due to megaconstellations like Starlink:

Here we propose a new metric, the CRASH Clock, that measures such stress in terms of the timescale for a possible catastrophic collision to occur if there are no satellite manoeuvres or there is a severe loss in situational awareness. Our calculations show the CRASH Clock is currently 5.5 days, which suggests there is limited time to recover from a wide-spread disruptive event, such as a solar storm. This is in stark contrast to the pre-megaconstellation era: in 2018, the CRASH Clock was 164 days.

Kessler syndrome could be a solution to the Fermi paradox.
