Who’s Afraid of the Multiverse?

Urbi et Orbi

“In their efforts to solve fundamental problems in cosmology, many researchers have converged on the idea of a multiverse — the theory that a vast number of universes lie beyond the limits of what we can observe.

Because they’re unobservable, multiverse theories are also untestable, blurring the line between science and speculation and making them controversial in the scientific community. Princeton University physicist Paul Steinhardt has called the multiverse “a dangerous idea that I am simply unwilling to contemplate.” By challenging both humanity’s uniqueness and our central place in the cosmos, multiverse theories have also become embroiled in theological debates  — some fear they will join evolution as another battleground in the culture wars.” (Seed)
