Is Cybertruck's glass really unbreakable? What's the strongest glass in the world?

Who can forget when Elon Musk proudly boasted that the glass in his Cybertruck was unbreakable only to have it shatter moments later?

According to the CEO, the glass was indeed very sturdy, it just lost its stability when the vehicle door was hit with a sledgehammer in an earlier part of his demonstration.

So what is really strong glass? Perhaps bulletproof glass? This material is very strong but not completely bulletproof as its name suggests.

It’s typically made by layering a polycarbonate material between pieces of ordinary glass. The more layers are added, the more protection it can provide, allowing the glass to absorb the bullets’ energy.

The glass in the Cyrbertruck is supposed to be bulletproof but it’s still unclear exactly how it’s made. They call it the Tesla Armor Glass, and it has been described as an “ultra-strong glass and polymer-layered composite” that can absorb and redirect impact forces.

Musk himself has said that the glass is basically transparent metal, but has never revealed the exact engineering behind the material.

But Tesla’s Armor Glass is not the toughest glass out there.

In 2011, researchers from Caltech and the Department of Energy’s Lawrence Berkeley National Laboratory announced the introduction of a metallic glass that was stronger and tougher than steel, beating out any other known material.

How was this glass made and how exactly does it compare to other bulletproof glass?
