Same stock is listed in more than one place, and also e.g. stock movements in NY affect stocks in London. There are undersea cables built for this purpose: https://www.popularmechanics.com/technology/infrastructure/a...
What a waste of human ingenuity. And I thought ad-tech was bad enough
Can someone explain the physical layer aspects of starlink? Is the spectrum same as mobile data spectrum or does it work with different part of spectrum. If it is different part, do we need specific hardware to receive and transmit? Are there any interference/loses issues that might popup when scaled? What is stopping spaceX to provide internet outside US?
Almost certainly has its own slice of spectrum. You need a pizza-box sized antenna set up, so it's not quite person-portable yet, but not too bad for installing on a vehicle.
> Are there any interference/loses issues that might popup when scaled?
Each satellite only has so much bandwidth. So the more people using it in the same area, the worse it's going to get. In theory they'll add more satellites as needed, but it's never going to be much good for towns/cities.

Ground stations and regulations. Once they have satellite-satellite communications running the ground stations become less of an issue (though there's a latency penalty if your signal has to go a long way round the satellites before getting to the ground).
The true question is: may I be able to play an online video game in the deep Sahara before the modern human civilization collapses?
50ms ping should be reasonable for most games. whippersnappers who complain about 20ms ping should watch some quakeworld or quake 3 cpma where this dude rat used to destroy everyone on 300ms.
Fantastic. I'm keenly curious on how this will work with national regulations. Having a single global ISP is very attractive on the surface and that's with the huge caveat on monopoly, but as an additional option. I'm just not sure how this will interact with some nations' policy/restrictions. Looking at this aspect very much.
This is amazing. I know there will be latency issues, but for majority of web browsing, videos, etc, it shouldn't matter. We are entering the era of spacenet and the future looks bright. Imagine having devices as small as phones or set-top boxes that can directly access internet using satellites. It would lead to a revolution in many industries.
In my experience (multiple clients in rural area) low speed (1.5 Mbps) with low (50 to 80 ms) latency will outperform 40Mbps/800 ms latency connections for video. Web browsing, of course, isn't really affected by latency.

Why would HFT even consider using it? They are located as close as possible to the exchange they operate on, not across states or halfway across the world.
Arbitrage between multiple exchanges requires data to go from exchange A to exchange B as fast as possible. Light in vacuum is faster than light in fiber.
