  • Just to add to this, because it’s fascinating. GPS satellites signals are about as strong as radiation from a light bulb, 20000km away. The signal that arrives on earth is 20db weaker than the noise floor, so background noise is a lot stronger than the signal is.

    The way it works is that the background noise is random and the signal is repeated many times a second, so you can split the signal and add it together. The random background noise averages out and you’re left with a strong signal. But due to this, it’s enough to have a very weak signal that adds non random noise on the correct frequency for it to just break.

    And actually what I desribed above is just the first layer of a GPS signal, it gets a lot more complicated with signals within signals, it’s pretty crazy how well it works. this is an amazing write uo on how the signal actually works, in case anyone is interested



  • Those are not the same things… Glass is better for the environment, for one it doesn’t break down into microplastics which get everywhere. And glass can be recycled indefinitely (minus some loss due to impurities) whereas plastic can be recycled up 0-1 times usually.

    Plus the whole “it’s up to consumers to solve this” is just corporate propaganda to absolve themselves of any responsibility, all the while not offering any alternatives that a consumer could pick from. Like literally, they paid for marketing campaigns to convince the public that it was our fault.
