Will we grab the universe? Grabby aliens predictions.

Video Description

In the previous video, we talked about why humanity seems to have appeared very early in the universe: among the first civilizations that could ever appear. Earliness constitutes a riddle. It makes humanity’s situation seem rather mysterious. Robin Hanson, who introduced the idea of the great filter, solves this riddle by postulating that civilizations that he calls “grabby” will soon fill the universe. As anticipated, grabby aliens are the main assumption of a detailed model describing how such aliens expand and distribute in the universe. The model makes many interesting predictions, such as when we’ll meet grabby aliens, our chances of hearing alien messages, and becoming an interplanetary civilization ourselves. It also answers why we don’t see aliens yet, considering the universe’s large number of stars and galaxies. These predictions are the topic of this video. ▀▀▀▀▀▀▀▀▀PATREON, MEMBERSHIP, KO-FI▀▀▀▀▀▀▀▀▀▀▀▀▀▀▀▀▀ 🟠 Patreon: https://www.patreon.com/rationalanimations 🟢Merch: https://rational-animations-shop.fourthwall.com/ 🔵 Channel membership: https://www.youtube.com/channel/UCgqt1RE0k0MIr0LoyJRy2lg/join 🟤 Ko-fi, for one-time and recurring donations: https://ko-fi.com/rationalanimations ▀▀▀▀▀▀▀▀▀SOCIAL & DISCORD▀▀▀▀▀▀▀▀▀▀▀▀▀▀▀▀▀ Twitter: https://twitter.com/RationalAnimat1 Discord: https://discord.gg/hxWBm6sBNU ▀▀▀▀▀▀▀▀▀SOURCES & READINGS▀▀▀▀▀▀▀▀▀▀▀▀▀▀▀▀▀ Robin Hanson's paper on Grabby Aliens: https://grabbyaliens.com/paper Grabby Aliens website: https://grabbyaliens.com/ The Great Filter - Are We Almost Past It? https://mason.gmu.edu/~rhanson/greatfilter.html The Grabby Aliens Model — 3D Sim, by Daniel Martin: https://youtu.be/oLvzFJLLfCY ▀▀▀▀▀▀▀▀▀CREDITS▀▀▀▀▀▀▀▀▀▀▀▀▀▀▀▀▀ Writer: Emanuele Ascani Animator: Michela Biancini Narrator: Robert Miles ▀▀▀▀▀▀▀▀▀PATRONS▀▀▀▀▀▀▀▀▀▀▀▀▀▀▀▀▀ BIG thanks to our patrons from the simple adder tier and above: Gabriel Fair Bleys Goodson Francisco Lillo Kevin Ma Krishna Penukonda marverati Michael Zimmermann no special person Trevyn Case Noah Corwin Austin Cluff Connor FusionOak Mark Gongloff Marty Betz Matthew Brooks Neel Nanda Perry Jackson rictic Robin Hanson Ryouta Takehiko Yegor Gagarinov Ana Tomasovic Ashten The Platypus Bryan Egan Calvin McCarter Chris Chapin Craig Ludington Jacob Van Buren Jeroen De Dauw JHeb Lars Osborne Luke Freeman Meade Marmalade Nathan Nathan Fish Nicholas Kees Dupuis Raphaël Lévy Roboroger Sephiths Superslowmojoe Tim Duffy Z ▀▀▀▀▀▀▀MUSIC ATTRIBUTION▀▀▀▀▀▀▀▀▀▀▀▀▀▀▀▀▀▀▀ Dreams Become Real by Kevin MacLeod is licensed under a Creative Commons Attribution 4.0 license. https://creativecommons.org/licenses/...
