Study Notes
Formation of the Solar System
- The solar system formed from a nebula, a cloud of gas and dust, approximately 4.6 billion years ago.
- The nebula collapsed due to its own gravity, accelerating its spin.
- The spinning nebula flattened into a disk structure.
- Hydrogen and helium, the universe's most abundant elements, comprised the majority of the disk.
Why does the solar system have a disk shape?
- Collisions between particles within the nebula led to the flattened shape.
- These collisions caused particles to lose vertical momentum, resulting in a thinner, flatter disk over time.
- The law of conservation of angular momentum explains this loss of vertical momentum.
Why doesn't the solar system have a spherical shape given that space is 3D?
- In three-dimensional space, particles in a spinning cloud can move in any direction, including up and down, in addition to orbiting the center.
- Collisions between particles cause a reduction in vertical momentum, ultimately forming a disk.
- In a four-dimensional space, particles would have two planes of rotation, preventing the loss of vertical momentum through collisions.
- Consequently, a four-dimensional cloud would retain its spherical nature.
- The three-dimensional nature of space is fundamental to the formation of disk-like structures.
Is the solar system unique?
- No, numerous other planetary systems show disk-like structures, evidenced by observed exoplanets.
- Many galaxies exhibit a disk-like structure too.
- Saturn's rings and accretion disks surrounding black holes also display this flat shape.
- The flattened shape is a common characteristic of spinning systems throughout the universe.
