Theories of cosmology based on a multiverse are flawed, says Lee Smolin, author of the bestselling science book The Trouble with Physics and a founding member and research physicist at the Perimeter Institute for Theoretical Physics.

Smolin points out why a timeless multiverse means that our laws of physics are no longer determinable from experiment and how the connection between fundamental laws, which are unique and applicable universally from first principles, and effective laws, which hold based on what we can actually observe, becomes unclear.
