Ice has a lower density than the density of water.
Galactic recycling is a natural phenomenon in which the stars expel some gas into the space so that it would mix with the interstellar medium. As a result, this would produce new younger stars. So, basically, the concept done here is the mass and energy conservation. In order to create new species, the energy must come from another source.
Answer:
Electrons have negative charge.
So this can explain the density of a person very clearly.
