He points out that the Titanic sank after its hull was damaged by hitting the underwater part of an iceberg, which wouldn't be possible if it were made of dark matter. The questioner in the audience misunderstands the metaphor by taking it literally, thinking that Ponytail is saying that the part of an iceberg below the surface is literally made of dark matter. So baryonic matter is like the "tip of the iceberg," visible to us above the surface, while dark matter is like the invisible majority of the iceberg below the surface. Excluding dark energy, dark matter accounts for about 85% of the total mass of the universe. Dark matter is known to not interact at all with ordinary baryonic matter except by gravity, and has been detected only by its gravitational effects. ![]() In this case, Ponytail is using it to illustrate the fact that about 95% of the mass in the universe does not appear to be in the form of ordinary (" baryonic") matter, but rather dark matter and dark energy. Just as real a iceberg floats with the vast majority of its body below the water's surface (often simplified as 90%, which does quite closely reflect the general range of buoyancy for ice in cold sea-water), the iceberg as metaphor represents a system where the large majority is unseen, invisible, or hidden in some way.
