Just this month, based on quantum mechanics, mathematician Tim Andersen says maybe and theoretical physicist Sabine Hossenfelder says no. Based on cosmology, the study of our universe, physicist George Ellis said yes last June. With free will, as with consciousness, we don’t fully understand what’s involved. All insights from science are partial so we can’t look to science for a definitive answer. But maybe science can offer some hints.
