Facts about the Multiverse
- 08
Gravitational lensing observations of galaxy cluster Abell 1689 reveal temperature fluctuations in the cosmic microwave background consistent with predictions that cold spots could indicate collision signatures between adjacent bubble universes in an eternally inflating multiverse.
- 07
Physicist Andrei Linde's eternal inflation theory predicts that universes spawn from quantum fluctuations within existing universes, creating a self-reproducing multiverse where pocket universes continuously bud off from parent universes.
- 06
Observable evidence from the cosmic microwave background suggests our universe's geometry may be flat or negatively curved, implying space extends infinitely and potentially contains infinite copies of our multiverse region.
- 05
The Many-Worlds Interpretation, proposed by Hugh Everett in 1957, suggests that every quantum measurement spawns branching universes where all possible outcomes physically occur rather than collapsing into one reality.
- 04
Quantum decoherence experiments suggest that observing a quantum system collapses its wave function into one state, supporting the many-worlds interpretation where all possible outcomes occur in separate branching universes.
- 03
String theory landscape calculations suggest approximately 10 to the 272nd power possible vacuum states, each potentially representing a distinct universe within the multiverse.
- 02
Cosmic inflation theory predicts that our Big Bang was one of infinitely many simultaneous Big Bangs occurring across a vast eternally inflating spacetime, generating the inflationary multiverse model.
- 01
In 2011, physicist Juan Maldacena's work suggested the multiverse could contain 10 to the 500th power distinct universes with different physical laws.
