The World in a Billion Years: Top 5 Future Technologies

Five Speculative Technologies in a Billion Years

The video imagines five highly speculative technologies humanity might develop in a billion years. These ideas are presented as future possibilities, not established scientific predictions.

1. Wormhole Networks Across Galaxies

Vast particle accelerators could create millions of wormholes, allowing people and robotic probes to reach distant galaxies. Wormhole hubs would group connections to destinations at different distances.

2. Travel to Other Universes

Humanity could use wormholes and hyperspace to enter younger, parallel universes with similar physics but less dark energy. The video imagines these universes as sources of energy and describes advanced technology that might seem paranormal to less advanced civilizations.

3. Black-Hole Computers

The video proposes that sufficiently massive computers could collapse into black holes, which it calls the ultimate computers. It also describes computation involving quantum entanglement between particles associated with a black hole, as well as planet- or star-sized computers and vast numbers of human minds merged with them.

4. Reversing Cosmic Expansion Locally

To counter the threat of accelerating expansion and a possible “Big Rip,” humanity could harness dark energy and manipulate extra dimensions. A gigantic sphere would supposedly reverse dark energy’s effect within its boundary, allowing galaxies and stars inside to continue evolving normally.

5. Creating Small Universes

Humans could trigger Big Bang-like events in hyperspace to create miniature universes. The video speculates that their microscopic components could be controlled and made intelligent, and that some universes might contain nested simulations.
