Solar systems, planets, spiral galaxies. (Atoms?) What causes objects to spin, rather than just wobble around?

Planets spin because of the conservation of angular momentum. When the solar system was formed, it was a cloud of gas and dust that collapsed due to gravity. As the cloud collapsed, it started to spin faster and faster, and this spinning motion was preserved as the planets formed. This is similar to how an ice skater spins faster when they pull their arms in.
Galaxies spin for the same reason as planets – the conservation of angular momentum. When the universe was formed, it was a cloud of gas and dust that collapsed due to gravity. As the cloud collapsed, it started to spin faster and faster, and this spinning motion was preserved as galaxies formed. However, the exact mechanisms for galaxy formation and spin are still being studied and debated among scientists.
Solar systems spin because of the same underlying principles as planets and galaxies. As the cloud of gas and dust that formed the solar system collapsed, it started to spin faster and faster due to the conservation of angular momentum. This spinning motion was then transferred to the planets and other objects in the solar system as they formed.
Spin plays a crucial role in the formation of solar systems, planets, and galaxies. Without the initial spinning motion, these systems would not have formed in the first place. The spin also helps to shape the objects and can influence their orbits and interactions with other objects in the system.
Yes, the spin of these systems can change over time. External forces, such as gravitational interactions with other objects, can cause a change in the spin. Additionally, internal processes, such as the transfer of angular momentum within the system, can also cause changes in the spin. However, the overall conservation of angular momentum principle still applies, so any changes in spin must be balanced out by changes in other parts of the system.
