The Ultimate Cosmology Quiz

Cosmology

• Cosmology is the branch of science that studies the origin, evolution, structure, and fate of the universe.
• The most accepted theory for the origin of the universe is the Big Bang Theory.

Early Universe Eras

• During the Planck Era, the universe was smaller than an atomic nucleus.
• The era when the super force split into gravity and GUT (Grand Unified Theory) force is called the Grand Unified Theory Era.
• During the Grand Unified Theory Era, the expansion of the universe was caused by the asymmetry between matter and antimatter.

Earth Science

• The atmosphere, which comprises the air we breathe, is composed of gases such as nitrogen, oxygen, and others.
• The lithosphere comprises the solid layer of the Earth.
• The hydrosphere comprises 70% of the Earth's surface, which is water.

Biology

• The biosphere pertains to life forms, which includes humans.

Interconnectedness of Systems

• The subsystems (atmosphere, lithosphere, hydrosphere, and biosphere) are interrelated and interconnected.

Historical Figures in Astronomy

• Aristarchus was the first to propose that the Earth was not the center of the universe.
• Philolaus believed that the central fire was actually the Sun, and seconded Aristarchus' Heliocentric model.
• Aristotle believed that the center of the cosmos is the Earth.
• Claudius Ptolemy popularized the geocentric model, wherein celestial bodies revolved around the Earth (Ptolemaic model).
• Albert Einstein proposed that the universe was a finite and static closed four-dimensional sphere, where matter spread smoothly throughout space.

Geology

• Rocks are composed of minerals, which are naturally occurring substances that build up the Earth's crust.
• Geologists use the physical properties of minerals to identify newly discovered minerals.
