7. Λ and the Multiverse Theories
Modern physics suggests that the value of the cosmological constant might not be unique to our universe.
In some multiverse theories, each universe could have a different Λ, dramatically impacting its evolution and stability.
A universe with a much larger or smaller cosmological constant might collapse quickly or never form galaxies at all.
This idea raises profound questions about why our universe’s Λ is just right to allow stars, planets, and life to exist.
