a concept that we never learnt in schools

Infinity is not just “endless” — there are different sizes of infinity.
In this video, I explore one of the most mind-bending ideas in mathematics:
why the infinity of points on a line is far bigger than the infinity of whole numbers.

Using a light projection technique, I show that no matter how long or short a line segment is, all line segments contain the same number of points. This challenges our everyday intuition that “longer means more.”

We dive into:
Why every line segment has equal point-infinity
The density property of a line (there is always another point between two points)
Why points on a line cannot be paired one-to-one with whole numbers
Georg Cantor’s idea of cardinality
What ℵ₀ (aleph-null) really represents
Why the cardinality of the continuum is strictly larger than countable infinity

This video is not about formulas — it’s about seeing infinity differently.
If you’ve ever thought all infinities are the same, this will change how you think forever.
