What is the arrangement of the objects in the universe from largest to smallest
http://www.physics.hku.hk/~nature/CD/regular_e/lectures/chap01.html
To determine the arrangement of objects in the universe from largest to smallest, we can consider various scales and structures. Here is a generalized arrangement:
1. Cosmic Scale:
At the largest scale, we have structures such as:
- Superclusters: Groups of galaxy clusters.
- Filaments: Vast cosmic "web" composed of galaxy clusters, superclusters, and intergalactic gas.
- Cosmic Microwave Background Radiation (CMBR): Thermal radiation remaining from the early universe.
2. Galactic Scale:
Moving to a slightly smaller scale, we have:
- Galaxies: Vast collections of stars, gas, dust, and dark matter.
- Galaxy clusters: Groups of galaxies held together by gravity.
- Local Group: A small cluster of galaxies including the Milky Way.
3. Stellar Scale:
On the stellar scale, we find:
- Stars: Massive, luminous objects fueled by nuclear fusion.
- Solar Systems: Stars with planets and other celestial bodies orbiting around them.
- Planets, moons, asteroids, and comets: Various celestial bodies that orbit stars.
4. Subatomic Scale:
As we delve into the smallest scales, we encounter particles and elements:
- Atoms: Basic building blocks of matter consisting of a nucleus (protons and neutrons) and electrons orbiting around it.
- Subatomic particles: Protons, neutrons, electrons, and various other elementary particles.
It's important to note that this arrangement is not exhaustive, as there are many other substructures and elements within each scale. Additionally, new discoveries and scientific advancements may lead to updates and refinements of our understanding of the universe's organization.
