Noujoum

“Noujoum” would like to make these same ideas sensible, to bring out the celestial objects through the emergence of sound masses, to orchestrate their race, their trail, their disappearance.

For scientists, all the structures observed in the Universe were formed by gravitational collapse due to differences in density. The denser areas create a higher gravity and attract the matter around them while becoming denser. When density becomes too high, other processes come into play and limit growth.

The pressure forces can become important if it is a gas (we then witness the appearance of acoustic waves) or a solid (as in the case of planets) or more subtle phenomena, such as diffusion, free propagation or violent relaxation in the case of dark matter, can occur. Small structures begin to collapse before larger ones, and large structures are formed by incremental or agglomeration of smaller structures already formed. Some objects are formed by fragmentation of a gas cloud cooling down. This is the case of stars. During this transformation the substructures are partially destroyed. It thus remains in the new structures the traces of the oldest. Halos, granularity, clusters, waves, the universe of the Universe looks terribly like a musical score. “
