Ever feel like you’re taking up too much space? Turns out, you’re actually made of almost nothing at all.

In this episode of Brain Blast, hosts Jordan and Alex peel back the layers of reality to reveal the "ghost" inside the matter. We dive into the startling fact that atoms are 99.9999% empty space. If an atom were the size of a massive football stadium, the solid nucleus would be nothing more than a tiny marble sitting on the 50-yard line—leaving the rest as a vast expanse of nothingness.

Why Can’t We Walk Through Walls?

If we are mostly empty space, why do we keep bumping into things? Jordan explains the quantum mechanics behind our "solid" world:

• The Electron Cloud: Electrons zoom around the nucleus so fast they create a "shield," much like the spinning blades of a fan looking like a solid disc.
• Magnetic Repulsion: Because electrons carry a negative charge, they repel the electrons of other objects. In reality, you have never actually "touched" anything in your entire life; you are just hovering incredibly close.

Where Does Your Weight Come From?

If you are mostly empty space, why do you still have mass? The answer lies in a subatomic "dance party":

• Quarks and Gluons: Deep inside the nucleus, particles called quarks are held together by "gluons".
• Energy as Mass: These particles move at nearly the speed of light. Following Einstein’s famous equation,E=mc2, the sheer kinetic energy of this movement creates 99% of your body's mass.
