Earlier quoted context omitted.

I guess high frequency traders might be interested too then.

Aren't they all just across the street form wall street with exactly the same network ping as everyone else?

That doesn't help if you're transmitting information from Shanghai Exchanges to London trying to gain first mover advantage.

I saw something interesting the other day that I had previously missed: Starlink has the potential to provide lower latency around the globe than terrestrial fiber because light travels faster in vacuum than in optical silica fiber. "Delay is Not an Option: Low Latency Routing in Space" https://discovery.ucl.ac.uk/id/eprint/10062262/ http://nrg.cs.ucl.ac.uk/mjh/starlink-draft.pdf "We conclude that a network built in…

I wonder how the Starlink latency compares to the current microwave technologies used by high frequency trading firms. Any slight latency improvement is a game-changer in the HFT industry.

IIRC this is how they plan to finance it.

I'm really excited about this technology for selfish reasons. I love disconnecting and spending time in remote wildernesses. But paradoxically, being disconnected from technology gives me a lot of anxiety about technology. Working on devops roles over the last decade, I've almost never had a time when I can just forget about it all. Even when I'm not on call, and no matter how well I try to document things, I'm often…

Why not just use any of the number of existing satellite telecoms providers?

There's not as many as you think, and they all blow. Not enough bandwidth, way too much latency, and very very expensive.

I thought I read somewhere that they cancelled the plans to use lasers and were going to use radio instead. But now I can't find anything about it.

Radio and light have (for the purposes of this comparison) the same speed in vacuum.

How is the censorship going to work with Starlink? Twitter is heavily censored in many countries like Turkey.

Other countries censor other things, be it on political, commercial or "criminal" grounds.

Can someone explain a bit on these issues? Is the global internet going to be governed on US laws if Starlink becomes a thing?

Why would you do that?

The trades originate from elsewhere around the world.

This is a function of the permittivity of the material. A Vacuum is 1, the lowest possible. Air is 1.0006 so you won't see much difference.

Fiber optics of various types are usually on the order of 2 to 3 (closer to 2).

The current generation of Starlink satellites don't have satellite-to-satilite links, but I haven't seen any indication that that feature is canceled for future iterations.
