In this context “politics” clearly conveys “things directly related to governments, such as wars, elections, or socio-economical ideologies”. It is only a subset of the definition of politics that you’re probably using, something like “things direct or indirectly related to human groups and their conflicts of interest”.
We got a whole Lemmy to talk about Israel vs. Hamas, late stage capitalism, elections etc. We could - and should - have at least one community to chill and talk about other stuff, and without that rule we won’t have it. For example without that rule 99.99999% of the content as of late 2024 would be about Trump, as if Americans didn’t have multiple communities to talk about it already.
Okay, here’s a silly explanation.
Imagine two people want to communicate. They shall be named Alice and Bob. It’s night, and they’re too far away to hear each other; but each has an electric torch, and they can see the light coming off the other person’s torch.
Those torches are fancy. They have two settings: “strong” (big arse blinding light) and “weak” (wee light, but still visible). Let’s call a strong flash “1” and a weak flash “0” for short.
They also have a code, that they use to interpret the flashes of light that they send each other. Here it is; check the “binary” column. For example, if Alice sent Bob a weak flash, then a strong flash, then weak, strong, weak, weak, strong, strong, then Bob is supposed to interpret this as an “S”.
This is already enough to communicate. Like this:
Remember, each “0” is a weak flash and each “1” is a strong flash. When we decode it with the table from the link, here’s what you get:
Now. Messing around with the settings of a torchlight is slow, painful, and annoying. So is to watch closely for light flashes, write them down, and decode them with a table. So… let’s use machines to do so?
Okay, now let’s replace the torch. We want something that emits light that you can see from as far as reasonably possible; like, from Mars if you want. We could instead use light that has been amplified by radiation, it’s really strong and directed. The common name for that is “laser”.
