  • Climate stabilization on Earth is projected to be achieved through advanced geoengineering techniques involving atmospheric scrubbing and oceanic carbon sequestration, fully reversing anthropogenic damage from prior centuries.[199]
  • Terraforming efforts on Mars and select moons (such as Europa and Titan) will reach advanced stages, supporting fully self-sustaining ecosystems and human habitation by the 29th century.[200]
  • The cataloging and study of all known exoplanetary systems within 100 light-years will be completed, informing detailed astrobiological and astrophysical models.[201]

Social and cultural milestones

  • The continued evolution of posthuman societies, blending human and AI consciousness, is anticipated to create diverse cultural expressions and hybrid identities spanning physical and virtual realms.[202]
  • Major art movements will integrate neural interface technology, allowing direct sensory and emotional sharing between creators and audiences, revolutionizing experiential arts.[203]
  • Universal education systems will be fully digitized and personalized, accessible across planets, leveraging immersive virtual reality to eliminate geographical and socio-economic disparities.[204]

Other notable events

  • 2899–2900: A major interstellar festival is projected to celebrate the millennium of the metric system’s adoption and humanity's expanded use of universal standards in science, trade, and daily life across multiple planetary systems.[205]
  • Continuous monitoring of astronomical phenomena will likely witness the first confirmed observation of the Betelgeuse supernova if it occurs within this century, impacting astrophysics and interstellar navigation.[206]

30th century

  • 2931: Pluto will complete its second full orbit of the Sun since its discovery in 1930, taking approximately 248 Earth years per revolution.[207]
  • 2941: The 1,000-year copyright on the Long Now Foundation’s "Manual for Civilization" (created in the 21st century) will expire, assuming such copyright durations are respected over the millennium.[208]
  • 2957: The Greenland ice sheet may have significantly melted if global climate models predicting high greenhouse gas emissions continue into the future.[209]
  • 2967: Projected decay of certain ultra-stable isotopes such as xenon-124 may become detectable in deep time physics experiments — useful in refining the limits of particle physics.[210]
  • 2996: The 1,000th anniversary of the 1996 Summer Olympics in Atlanta, Georgia, may be commemorated as part of a long-term Olympic historical observance.[213]
  • 3000:
    • c. 3000: The North Star will no longer be Polaris due to the precession of the equinoxes. By then, the pole star will shift toward the star Errai (Gamma Cephei).[225]
    • Estimated timeframe when many long-term nuclear waste warning messages (e.g., at Yucca Mountain or WIPP) are designed to remain understandable and durable.[226][227]
    • According to Carl Sagan and others, advanced human civilizations may begin terraforming nearby planets such as Mars, depending on technological and ecological trends.[228]
    • The fictional setting of various sci-fi franchises, including the animated series Futurama, which portrays life in the year 3000 with advanced technology and interplanetary travel.[229][230]
