## FAQs
### Q: How dense is aerographene compared to air?
A: Aerographene has a density of 160 g/m³, which is significantly lower than air’s density of approximately 1,225 g/m³. This makes it one of the lightest solids ever produced.

### Q: What is aerographene made of?
A: It is composed of graphene, a single-atom-thick layer of carbon atoms arranged in a two-dimensional hexagonal lattice. This structure contributes to its ultralight yet robust properties.

### Q: Is aerographene a type of aerogel?
A: Yes, aerographene is classified as a subclass of aerogel, a synthetic material known for its low density and high porosity. It inherits aerogels’ ultralight characteristics but is distinguished by its graphene-based composition.

## Why It Matters
Aerographene represents a groundbreaking achievement in materials science due to its unprecedented low density, outperforming all other solid materials. Its existence challenges conventional understanding of structural integrity at extreme lightness, opening avenues for transformative applications in aerospace, energy storage, and insulation technologies. As the lightest solid, it addresses critical needs for weight reduction in engineering and environmental solutions, exemplifying human innovation in manipulating matter at the atomic scale.

## Notable For
- **Record-Breaking Density**: Recognized as the least dense solid material, with a verified density of 160 g/m³.
- **Graphene-Based Innovation**: First aerogel to leverage graphene’s unique properties, combining low density with mechanical strength.
- **Ultralight yet Robust**: Maintains structural stability despite being lighter than air, a paradoxical feat in materials engineering.

## Body
### Classification & Composition
Aerographene is a synthetic material classified as a subclass of aerogel, inheriting the latter’s ultralight and porous characteristics. Its primary component is graphene, a two-dimensional carbon lattice, which forms a three-dimensional network in aerographene’s structure.

### Technical Specifications
- **Density**: 160 grams per cubic meter, achieved through its highly porous graphene framework.
- **Aliases**: Often termed "graphene aerogel" in academic and technical contexts.
- **Metadata**: Documented under Wikidata with identifiers including a Freebase ID (`/m/0vztw7k`) and a discontinued Microsoft Academic ID (`33036341`).

### Comparative Significance
Unlike conventional aerogels (e.g., silica-based), aerographene’s graphene composition enhances its mechanical resilience while maintaining ultra-low density. This dual functionality positions it as a superior candidate for applications requiring both lightness and strength, such as in next-generation aerospace materials or high-efficiency thermal insulators.
