Physical science

Big Bang Theory

The rapid expansion of the universe that caused it to cool down and form new particles.

Nucleosynthesis

The formation of protons and neutrons shortly after the Big Bang, leading to the creation of hydrogen nuclei.

Deuterium

The combination of protons and neutrons to produce deuterium nuclei and gamma rays, contributing to the formation of light elements like helium.

Nuclear Fusion

The process in which high energy and temperature cause neutrons and protons to combine, forming heavier atomic nuclei.

Light Elements

Hydrogen, helium, lithium, and beryllium, which are created through nucleosynthesis and nuclear fusion.

Isotopes

Variants of an element with the same atomic number but different atomic mass number.

Supernova

A massive explosion of a star.

Quarks and Electron

Particles that formed as the universe cooled down after the Big Bang.

Neutron Star Merger

The process of creating heavier elements by adding more neutrons to existing nuclei, rather than through fusion of light nuclei.

Proton

A positively charged subatomic particle.

Neutron

A neutrally charged subatomic particle.

Electron

A negatively charged subatomic particle.

Stellar Nucleosynthesis

The process of creating elements within stars by combining protons and neutrons from lighter elements' nuclei.
