      fun fact, that would make the transmission slower.

      According to wikipedia cat5 cable has a propagation delay of 5.30 ns/m, which works out to about 62% of the speed of light. While radio waves propagate at the speed of light.

        Yeah, the reason ethernet is generally faster compared with wifi is mainly due to interference from physical objects between the device and the transmitter. Not as much an issue when you’re issuing commands into the vacuum of space from large, high-powered antennas.

        Radio waves always propagate at the speed of light, it’s just that the effective speed of light in copper and glass fibre is lower than that in air/vacuum.

        This means that if you have long cables at some distance you’ll get a lower delay by using low earth orbit satellites like Starlink. Assuming a total distance via satellite of 1000km and the effective speed of light in glass fibre to be 2/3 c, cables over 667km will have a higher delay than the satellite.

          Some fiber-optic cables are faster than others, because they’re full of air. Hollow-core fibers have a large central cutout and/or a close hexagonal packing of smaller glass tubes. The latter are technically a “photonic crystal.”

          Speed of light in fiberoptic cable is slower than c for a different reason. The light is in something close to vacuum, signals travel slower than c because the light doesn’t follow a straight path, it zig zags bouncing off the walls.

          A radio wave or laser in reasonable vacuum (in orbit for example) will be lower latency than a signal on a fiber link the same length

          I’m expecting lower ping via starlink than fiber once starlink has laser links between satellites

    It’s not like they “play” competitive real time over there. It’s more turn based single player

    Well NASA is essentially botting. It’s not like they need to sit there and give it every input. They tell it what to do and it follows a program. I could bot with that much ping if my bit is running locally on the game’s servers. Basically: NASA is full of cheaters.

      Yeah wtf, 100ms is great.

      300ms is the average reaction time in humans. Less than 100ms reaction time would be insane and I’m pretty sure it’s something no one has actually achieved.

      Lemmy.nz has had some serious problems with federation with World, and a few other instances, because the way federation works, or worked, is an item would be sent, the receiving server would acknowledge receipt, and the next thing would be sent.

      We ended up four days behind at one point.

    Don’t let your ping hold you back. I bought one of the COD games a few years ago and my PC would not run it no matter what I did with the settings (I think my processor was the problem). Usually it crashed before I even got into a game but I was actually able to join 2 of them and it was like playing a PowerPoint presentation of COD. The one game I actually able to finish I was still in the middle of the pack for k/d…
