Perhaps our universe isn’t as finely tuned as we thought! We know that life requires stars and planets to form. Overly rapid expansion of the universe would prevent this from happening and a larger amount of dark energy means that the universe expands more rapidly. Yet a recent paper shows that the amount of dark energy in the universe could be hundreds of times larger and yet still permit stars and planets to form. This result seems to reduce the role of fine-tuning, right? Sort of, but not really. In fact, this discovery makes multiverse explanations for the intricate balances that life requires even more difficult to accept—if you demand a purely naturalistic multiverse.
How Does the Multiverse Attempt to Explain Fine-Tuning?
