Physics

Is global warming caused primarily by humans?
Since the industrial revolution, humans have been emitting greenhouse gases that the Intergovernmental Panel on Climate Change (IPCC) believe are responsible for Global Warming. While the majority of climatologists agree with the IPCC's conclusions, skeptics suggest that the IPCC's climate models are flawed and that recent climate changes should be attributed to natural causes.

Is the many worlds interpretation of quantum mechanics correct?
The many worlds interpretation of quantum mechanics says that a quantum event doesn't have a single random outcome, but rather all possible outcomes, meaning that each event splits the universe into multiple divergent universes that exist in parallel.

Must all explanations be compatible with the laws of physics?
The laws of physics are foundational to all of science, describing with mathematics the basic ways in which the physical world behaves. Although physics doesn't provide the simplest explanation for everything - we need fields such as biology to explain emergent phenomena like life - it does require all explanations of the world to be compatible with physics. In contrast, some religious thinkers believe that this compatibility is impossible in explaining humanistic concepts such as free will.

Evolution

Does evolution violate the second law of thermodynamics?
The second law of thermodynamics states that entropy increases over time, or that a closed system moves from an ordered state to a random state. Critics of evolution suggest that life itself is prima facie proof that evolution is flawed, since the opposite appears to be happening - life has evolved from primordial soup to sophisticated creatures like ourselves. Defenders of evolution say that this objection is based on a misunderstanding of entropy.
