Flashcards

What is the Big Bang?

The Big Bang is the theory that explains the origin of all matter in the universe, a singular event that began the expansion and cooling of the universe from a state of extremely high density and temperature.

What does E=mc² mean?

Einstein's famous equation E=mc² describes the relationship between energy (E) and mass (m), demonstrating that energy can be converted into mass and vice versa, with the speed of light (c) being the conversion factor.

How are protons and neutrons formed?

Protons and neutrons, the building blocks of atomic nuclei, are formed from the combination of fundamental subatomic particles like quarks, bound together by the strong nuclear force.

What are the most abundant elements in the universe?

Hydrogen, helium, deuterium (a heavier isotope of hydrogen), and trace amounts of lithium are the most abundant elements found throughout the universe, formed in the early moments of the Big Bang.

Where do heavy elements come from?

Elements heavier than iron are primarily synthesized in the explosive deaths of massive stars, known as supernovae, where intense temperatures and pressures allow for nuclear fusion to create heavier elements.
