Science Capsules

Claims about unreliable temperature records, natural cycles, and overconfident models still circulate widely, and dismissing them unexamined convinces no one. The arguments here set the strongest skeptic cases against the evidence behind the human-caused-warming consensus, from CO2 records to how climate models earn their credibility. Working through both sides equips you to hold an informed position rather than an inherited one.

The UFO question splits into evidence-first investigation, government secrecy and oversight, the scientific search for alien life, and the cultural and psychological lenses we view it through. These approaches show where skeptics and open-minded researchers diverge on what the evidence actually supports. You can weigh the science against the speculation and reach your own view.

Why a brain produces felt experience remains the hardest open question about the mind. These arguments split on where to look: measurable integrated information in the brain's wiring, Buddhist accounts of mind refined over centuries, or a skeptical view that loose non-expert claims muddy the whole debate. Which one convinces you shapes what you believe about free will and yourself.

Science earns its authority by making predictions that could fail, and string theory doesn't. Against its popularity among physicists, the argument here places untestable theory closer to metaphysics than physics, however elegant the math. Taking this view means judging every theory by whether an experiment could ever prove it wrong.
