The obvious questions

What did scientists achieve by melting a diamond?

Scientists confirmed the carbon density paradox and unlocked potential for triple fusion gain.

What is the carbon density paradox?

The carbon density paradox refers to the unexpected behavior of carbon under extreme pressure and temperature conditions.

What are ice giants?

Ice giants are a class of giant planets, such as Uranus and Neptune, composed mainly of elements heavier than hydrogen and helium, including oxygen, carbon, nitrogen, and sulfur.
