Imagine soot so black that it looks like a hole cut straight through reality. 🕳️⚡ That's the idea behind Vantablack-like soot!

Technically, Vantablack soot isn't an official material name, but soot and Vantablack have an interesting connection.
🖤 What makes soot so black?

Carbon particles: Soot contains tiny carbon-rich particles that absorb some of the light hitting them.

Porous structure: Clumps of soot can trap light between their particles, causing repeated reflections and additional absorption.

Surface texture: Fluffy, uneven soot can appear much darker than a smooth black surface.

Ordinary soot

Dark, dusty carbon particles. It can look nearly pitch-black in the right lighting, but it scatters and reflects some light.

Vantablack

An engineered coating made using vertically aligned carbon nanotubes. Its microscopic structure captures light exceptionally well, making surface details seem to disappear.
🤯 Could soot become as black as Vantablack?

In principle, a carefully engineered carbon-based material with a suitably light-trapping structure can achieve extremely high absorption. But simply piling up more soot won't automatically make it equivalent to Vantablack.

Vantablack's special nanotube arrangement is the crucial difference.

The coolest part: If you coated a three-dimensional object with an exceptionally light-absorbing material, its shape could become difficult to recognize. Your eyes might see what looks like a flat, black void instead of a sphere or cube.

Imagine a ball of soot-black darkness floating in a room. You'd see its outline only where a little light revealed its edges. ⚫
