What about high frequency trading shops?
This is talking about radio wave frequency, not trading frequency.

Re: SpaceX punched a hole in the ionosphere
#132Commercial space is a tragedy of the commons in the making. What is its "carrying capacity", who calculated it, who enforces it? What are the long term effects, when do they kick in? What are potential secondary effects or tipping points? Astronomy is already a casualty as the sky stops being "dark". I guess who cares about fundamental knowledge when there is profit to be had.
Space is alot bigger than you think or make out, the effects on astronomy are short lived while they get into position

Only insignificantly. Most of the radiation is filtered/diverted by the magnetosphere. The only really practical effect of the disturbance is making the already hard to predict sky-wave propagation of HF even more harder to predict and characterize. Which is today realistically of an interest to HAMs and mostly as an fallback for intelligence agencies and diplomatic services. Edit: It also somewhat changes the scatte…

Yes, in fact at this moment commercial interests are petitioning the FCC to allocate bandwidth in the HF 2-25mhz range for the purpose of high-speed stock trading: http://www.arrl.org/news/commercial-interests-petition-fcc-f...
Re: SpaceX punched a hole in the ionosphere
#134Seems like this isn't considered to be a big issue, beyond that it is a very visible thing that instinctively 'feels' like a bad idea. > Rocket engines spray water (H2O) and carbon dioxide (CO2) into the ionosphere, quenching local ionization by as much as 70%. A complicated series of charge exchange reactions between oxygen ions (O+) and molecules from the rocket exhaust produce photons at a wavelength of 6300 Å–the…
It may not seem like a big issue but it speaks to the attitude of billionaires. I am no longer free to vent personal amounts of coolant from a refrigerator but Elon Musk can punch all of the holes he wants with his expensive rockets.
There are thousands of people responsible for planning, certifying and monitoring the operations of these launches. Within SpaceX, but also the launch site owners, the FCA, journalists covering it all. There are comprehensive environmental impact assessments, with opportunities for comments from the public. One of the thousands of people involved in all of that is a billionaire.
Furthermore it’s an issue that affects all launches, by ULA, NASA, ESA, whoever, not just SpaceX.
But sure, go ahead and ignore all of that and make a thoughtless dig against one person, in one country, running one rocket company for the crime of being successful at it.

It’s not just stroking egos; if you read any accounts by astronauts, there’s a profound effect on people that get a chance to look back at earth, and see how it’s actually not infinite. I hope every powerful person gets the chance to do that, I think it’d go a long way in reducing the petty bullshit we engage in.
You could do that with a VR headset

I would take the astronomers opinion [1] on how "big" is space over a throwaway HN shill reassuring me that I am idiot worrying too much.

The space industrial complex would pollute a whole lot more than today, and let’s hope space tourism it’s not something too feasible, aside from stroking egos it wouldn’t do much, space is very human unfriendly after all. I for one hope we move slower not faster.

Or, you know, you just check your ego from earth. Not sure how much of an impact the trip had on Bezos, and I wouldn't put my hope on such trips fixing the other ones.

I wonder what the total carbon footprint is of the Musk Empire. (Tesla + SpaceX + X + Boring Company + …)
And I wonder how many times over Tesla makes up for it.
The harm they cause to public transportation (such as politically stalling rail systems with Hyperloop) outweighs the good they do with their cars, especially now that car companies that don't directly hurt more efficient forms of transport are making electric cars.
And self driving taxis, if they ever do make it which is still waaaaay out even by Elon time, are not going to balance it out.

Will excess radiation leak through to Earth during re-ionization?
Don't believe the ionosphere has any role in any sort of radiation absorption, outside of RF?
The Ozone Layer is considerably lower than the Ionosphere proper, and protects all surface life from ionizing solar UV radiation. It most likely is as damaged by rocket exhaust as the ionosphere, and much more slowly healed.
That undoubtedly deserves its own article, which will unavoidably be confused with this one and be considered old news.

The needs of the many outweigh the needs of the few. (They can just be awfully hard to count, no matter who counts.)
The needs of the many outweigh the needs of the few. Glad to hear it! Because I know a large family that doesn't have a computer. I'll send you their address so you can mail them yours!
These families surely own a smartphone? You know the powerful computer in your pocket you potentially used to browse this website.
