Galaxy colonization simulations I’ve seen suggest colonization speed is exponential, so even a billion years added to the age of the universe should dramatically change things.
I think, if I recall, there was a study done recently that suggested we shouldn’t be too surprised if we have not seen aliens yet but probably soon, in the next 1000 years. But I can’t find the study - had 3D graphic of bubbles expanding outward and meeting.
If it’s true this would affect the Drake Equation quite a lot I would think, making it even more puzzling why there are no aliens yet. Unless most of this new time at the start of the universe was uninhabitable.
And no Uranus jokes yet - well done Fediverse. Now hold the line, hold!
Copy paste of my research:
Nostr
Nostr is a Twitter alternative that’s decentralized, not a Reddit alternative.
Nostr is not P2P. Its a broadcast protocol. Nostr is pub/sub, distributed, decentralized; while others such as Matrix,mastodon, bluesky are federated and are somewhat closed than nostr.
Nostr is just a protocol - a structured way to send and receive data. Not tied to one-email or a centralizd service for identity. Anyone can create anything on top of nostr. (https://www.reddit.com/r/nostr/comments/14ea9y3/whats_the_difference_between_nostr_matrix/)
No, they (Nostr) are not doing ActivityPub. ActivityPub requires server-to-server communication, which Nostr does not have. They only have client-server communication. And the actual protocol is different to ActivityPub, all the way from the transport (which uses WebSockets rather than HTTP REST) to the schemas of the objects being passed. They also rely much more heavily on public key cryptography.
Nostr takes decentralization too far to be practical for a wide audience IMO. The relay model is even more abstract than Mastodon instances (which can at least be analogized to e-mail hosts) and the public/private key system is both inaccessible (copy/paste a key or look people up in a directory-- like a phone book! Friend codes on steroids) and unforgiving (no password resets). Like much of crypto, there are interesting ideas that don’t seem practical in actual use. Curious if it pans out.

But unlike ActivityPub, the Nostr protocol is extensible with NIPS (https://github.com/nostr-protocol/nips) so maybe there is hope to fix these problems (https://kbin.social/search?q=nostr)

That’s exactly it, thx.
