Why is the most common element in the universe so rare on Earth?

The universe is dominated by hydrogen and helium, but on Earth, these elements are surprisingly scarce, accounting for less than 1% of our planet. This video dives into the fascinating reasons behind this cosmic paradox.

We explore how hydrogen was massively created during the Big Bang and why Earth's gravity isn't strong enough to hold onto these light gases, especially compared to giants like Jupiter. We also detail the unique case of helium, a noble gas that rarely bonds, leading to its near-total escape, and how the helium we do find is mostly a result of radioactive decay deep underground. Finally, we look at how hydrogen's ability to bond with oxygen (forming water) helps it stay on Earth, unlike its noble gas counterpart. Understand the science of planetary formation, gravity, and elemental abundance!
