Galaxies - A system of gas and dust and billions of stars, held together by gravity.
Cosmological - Relating to the origin of the universe.
PhD - An abbreviation for a Doctorate of Philosophy. Students study for several years and usually do their own extensive research to gain a PhD.
Black holes - A region of space where gravity is so strong that nothing can escape from it, including particles and radiation.
Dark matter - A hypothetical substance that can not be detected by scientific instruments. Its existence is inferred from evidence that the universe consists of more mass than we can perceive.
Big Bang - The moment the universe came into being. It is thought that this took place in a kind of explosion from a dimensionless singularity.
Quantum mechanics - A fundamental theory in physics describing the properties of nature on an atomic scale. Unlike general relativity, which works when applied to large objects, quantum mechanics helps describe the world on a tiny level - at a scale where things can be in several places at once, and measurement can affect reality.
