5. Only recent news is allowed.
Posts must be news from the most recent 30 days.
6. All posts must be news articles.
No opinion pieces, Listicles, editorials or celebrity gossip is allowed. All posts will be judged on a case-by-case basis.
7. No duplicate posts.
If a source you used was already posted by someone else, the autoMod will leave a message. Please remove your post if the autoMod is correct. If the post that matches your post is very old, we refer you to rule 5.
8. Misinformation is prohibited.
Misinformation / propaganda is strictly prohibited. Any comment or post containing or linking to misinformation will be removed. If you feel that your post has been removed in error, credible sources must be provided.
9. No link shorteners.
The auto mod will contact you if a link shortener is detected, please delete your post if they are right.
10. Don't copy entire article in your post body
For copyright reasons, you are not allowed to copy an entire article into your post body. This is an instance wide rule, that is strictly enforced in this community.

One man has control over the widest-spanning and quickest-to-establish communication systems during natural disaster scenarios. He has previously used this control to affect military operations of sovereign nations. He also has control over one of the largest social media platforms. Now, he is in the ear of the soon-to-be worlds most powerful person. (Assuming that person isnt already him, himself.)

And possibly also cause Kessler syndrome.

Would you get off that?
Sure, as soon as you read the links I have already provided, including the academic paper, and respond to them, unlike the other person I am talking to.
No, it couldn't. That's pure misinformation.
Kessler syndrome is only a possibility in orbits high enough that atmospheric drag is negligible. Starlink, by design, is at an altitude where the atmosphere is still thick enough to bring any debris or old satellites down to earth in a timely fashion rather than building up like Kessler syndrome requires. (To be clear, the air is still so thin that you'd need sensitive instruments to detect it at all. It's just enough to produce a tiny amount of drag, which adds up over weeks or months to lower the debris' orbit so that it meets thicker air)
There are plenty of perfectly legitimate objections you can raise to starlink without resorting to Kessler syndrome
There seem to be a significant number of people who disagree with you.

It's not possible with these satellites as they're too low in orbit and can only stay up for 3-5 years before burning up in the atmosphere. It doesn't matter if you can find people to agree with you as I could easily find a dozen links from people claiming the earth is flat.
Just to be clear... you believe because the satellites are low enough that they will only last a few years, that they cannot run into each other and cause a cascading effect of debris? I mean, sure, the cascading effect (Kessler Syndrome) might only last a few years, but it still could happen, couldn't it? Or is there something special about them that means they can't actually accidentally run into each other and break apart, with the pieces hitting other satellites and breaking apart...?
I'm not sure why these satellites being in low orbit protects them from the laws of physics.
You're talking about the Kessler Effect (cascading collisions) not Kessler Syndrome (space is unusable). I never stated that they can't collide with one another just that they're not capable of trapping us on earth for any significant period of time due to their low orbit.
I'm not sure why they think they know better than the multiple scientists I have given them references to.
Oh no wait, yes I do. They refuse to look at the links.
Well, where are the dozen links?
Except that my links quote scientists.
For example:
But a professor of astronautics is basically the same as a flat Earther, am I right?
Also, I literally included an academic paper.
The number of maneuvers increased as they increased the number of satellites in orbit, which shouldn't be surprising to anyone. To claim that this is going to follow an exponential curve approaching infinity is ignorant at best and disinformation at the worst because they have a hard limit on how many satellites they need. The guy you're quoting qualified that statement with "right now" right at the beginning of the quote.
In addition to this, an increased number of maneuvers has no bearing on whether these LEO satellites will cause Kessler Syndrome as you claimed in your previous comment. They're in too low of an orbit to do that.
That's quite the heel-turn from "I could easily find a dozen links from people claiming the earth is flat," but congratulations on taking a tiny bit of effort and reading the first paragraph of one of the many links I posted when I quoted it to you.
I'm sure looking at the academic paper I gave you wouldn't even be worth the time of someone with your expert knowledge.
Weird, though, that you say you could "easily find a dozen links from people claiming the earth is flat" and yet have provided no links to support your actual claim.
What heel-turn? I stated it isn't possible for these to cause Kessler Syndrome and haven't departed from that.
I did read your links when you initially replied, and they don't claim that they'll cause Kessler Syndrome. Some of them dance around the topic with scary sounding premises but none actually state it because it's impossible for something orbiting flying that low to be trapped in orbit for long just like an airplane with engines that die can't maintain altitude and continue flying for long. You don't need to be an expert in aeronautics or spaceflight to understand this because it's basic physics.
Yes I focused on that statement that you quoted because that's what you quoted in your reply as proof it's possible even though all it said was that more evasive maneuvers are happening as more of these satellites are put into orbit just like more cars will need to dodge debris in the road during rush hour than during the middle of the night when nobody is on the road.
I didn't post a list of flat earther links because neither one of us is arguing that the earth is flat. This statement was hyperbole to point out the flawed reasoning in thinking that your position is correct simply because you can find someone else stating the same thing (something those links don't actually even do if the topic is Kessler Syndrome). Yeah, they can crash into something and cause debris, but they can't be trapped up there permanently and prevent us from reaching space again because their orbit is so low.
Starlink orbits at 342 miles so assuming the entire constellation exploded into debris, they'd only be an issue for as little as a few weeks and as much as a couple of years before burning up and clearing themselves out. Kessler Syndrome requires that something be in high earth or geostationary orbit to trap us on the planet permanently.
https://aerospace.org/article/space-debris-101
No one said anything about permanently. That's been your whole issue here? Because that's not how gravity works anyway. The thing you yourself quoted says it could take years for it to reenter. So that's years of too much debris in LEO to launch anything safely.
I have no idea where you got the notion that Kessler syndrome means something like nothing can ever be launched again until the year 5 billion when the sun engulfs the Earth.
