The official client is an emacs package, interesting! These parts from the readme made me chuckle:

To consume and read other users’ feeds, you can read them manually, use a script, or a client.

Because of the decentralised nature it is very difficult to discover new users.

Strange how much higher the top one, 123456, is than the others, and how the most popular ones with repeating numbers also have 6 digits. Why do people like 6 digits so much more than 5 or 7?

Unfortunately yes. I’ve met people who ask chatgpt about absolutely everything such as what to have for dinner. It’s a bit sad honestly

This is interesting because the most “realistic” (i.e. still not realistic) depictions of time travel in fiction involve travelling through a singularity or wormhole. So you probably have to be in space to start with, but also both ends of the wormhole have mass so they can be orbiting a planet or star and stay within a stable distance of it. It solves this particular problem (just leaving the other usual problem of causality!) It also proves your point since it does allow travelling in space, in fact it allows travelling faster than light.

I think the converse is true as well, that if faster than light travel is possible then time travel must be possible, at least if you take relativity at face value. As others have pointed out there’s no universal reference frame, and for any journey that is faster than light in one reference frame, there is another frame in which the journey goes backwards in time.

Welcome!
