This doesn’t directly answer your question, but things would probably get very weird compared to our universe. Here’s an interactive visualization of a different weird universe with two time dimensions, Dichronauts by Greg Egan:

He really goes through the math on that site, so you might get some insight into how other topologies would look

I have standing orders to invade the Hague if ever tried there

There’s a sudden influx of users from instagram and tiktok and whatnot because of the ban, zuckerberg fellating Trump, and all of that stuff going on. So the answer to “What’s getting posted?” is “everything”

Signal has a lot of overlap there. They’ve got disappearing messages and Stories

Source hasn’t been released, but the dev has said it will be and there’s no reason to doubt that IMO. Same dev as pixelfed which is open source and federated

Looks like it’s still a load thing:

Pretty impressive you’re running it on a pi, even with how nice the 5 is 👍

Are you running all of the services at grey.fail on the same pi?

How big of servers are you using? Is the load just from syncing with pixelfed.social?

Pinging @jgrim@discuss.online since you run social.photo as a sister site to discuss.online

We’ve got !AskUSA@discuss.online for casual conversation about the US. You’ll likely get more opinions there than straight science, though
