🌃Universe and Solar System Formation🪐

Gravity

A Fundamental force that refers to the attraction of one body toward another.

Electromagnetic Force

This force binds atoms into molecules

Strong Nuclear Force

This force binds protons and neutrons in the nucleus together.

Weak Nuclear Force

This force breaks down an atom’s nucleus

Radioactive Decay

This describes the changes in an atom once it has become unstable

Singularity

This refers to a very small ball where all matter is compacted and has infinite density and intense heat.

Helium and Hydrogen

These were the first atoms to form as the universe cooled

Clumped Matter

Stars and Galaxies formed as a result of __

Edwin Hubble

He discovered that the Milky Way isn’t the only galaxy, and that galaxies are constantly moving.

Hooker 100 Inch Telescope

This is the telescope Hubble used to observe galaxies.

George Lemaître

He is the Father of the Big Bang Theory

Theory of General Relativity

This theory was applied to cosmology to propose that the universe is expanding according to Lemaître.

Primeval Atom

This is the dense point hypothesized by Lemaître where the universe formed

Hubble-Lemaître Law

A law derived by Lemaître where The recessional velocity of a galaxy is directly proportional to its distance from Earth.

Cosmic Microwave Background

This is the afterglow of the Big Bang, with no exact source.

Doppler Effect

This is the apparent shift in wavelength

Redshift

This is the occurence where galaxies recede further from the earth.

Big Bang Nucleosynthesis

Hydrogen, Helium and Lithium formed abundandly in the first few minutes if the universe through this process.

Solar Nebula

This is a vast cloud of gas and dust believed to be the starting point of the solar system

Planetismals

This is what the remaining debris formed as it collided and clumped together.

Asteroids

These are planetismals that failed to become planets

Carbon

An element abundant in the Asteroid Belt
