What is a Neutrino?

Neutrinos are particles that interact only via gravity and nuclear decay, making them invisible as they don't interact with light. Detecting them is challenging, akin to catching a bullet with a butterfly net. A common detection method involves using water tanks to observe Cherenkov radiation when neutrinos collide with electrons. The largest detector uses the Antarctic ice sheet. Neutrinos reveal that the universe is not symmetrical, as they are all left-handed, unlike other forces in physics.

What makes neutrinos difficult to detect?

• They are too large to be captured by detectors.

• They emit strong radiation that is hard to measure.

• They interact only with electromagnetic forces.

• They interact only via gravity and nuclear decay.

How can neutrinos be detected using water?

• By detecting Cherenkov radiation from electrons.

• By observing the water's temperature change.

• By measuring the water's pH level.

• By capturing the sound waves they produce.

What is the largest neutrino detector in the world?

• A deep-sea observatory in the Pacific Ocean.

• A satellite orbiting Earth.

• A balloon over the South Pole using Antarctic ice.

• A tank in the Sahara Desert.

What is unique about the handedness of neutrinos?

• They have no handedness.

• They are all left-handed.

• They are all right-handed.

• They can be both left-handed and right-handed.

How do neutrinos differ from other forces in physics when mirrored?

• They remain unchanged like gravity.

• They change their handedness.

• They become stronger.

• Their mirror image does not exist.
