Built to stump. Any score is bragging rights, and 9 or 10 earns the Genius title.

This hard science quiz mixes chemistry, physics, astronomy and biology into one tough challenge. You'll face questions on liquid metals, gem minerals, subatomic particles, blood types, temperature extremes and the edge of a black hole, with wrong answers built to tempt you. It's a genuine brain-buster, so any score you post is bragging rights, and the explanations make each question worth the struggle.

How to think like a scientist under pressure

The toughest science questions tend to live where the subjects overlap. Chemistry leans on physics, astronomy borrows from chemistry and biology depends on both. A question about the stars might really be about atoms, and a question about your body might turn on a bit of chemistry. That's what makes science such a rich subject for a brain-buster: there's always another layer underneath the one you know.

When a question stumps you, try reasoning instead of guessing. Ask what the answer would have to do or be, then check each option against that. Watch out for the classic traps, too. Plenty of people believe Earth has summer because it's closer to the Sun, but the seasons come from the tilt of Earth's axis. In fact, Earth is closest to the Sun in early January, during winter in the Northern Hemisphere. Tempting wrong answers are often real terms from a neighboring topic, so ask yourself which choice fits the exact wording.

Remember that science is built on revision. Ideas are tested, challenged and refined over time, which is why the history of discoveries is full of brilliant people who were partly right. This quiz is meant to be tough, so every answer you get is a win worth sharing.
