Final answer:
The Big Bang theory suggests that the universe began as a singularity and expanded over time. Mass, volume, and density are important in understanding this theory. The universe started from a point of infinite mass and density, and as it expanded, this mass was spread out over a larger volume, causing a decrease in density.
Step-by-step explanation:
The Big Bang theory explains the origin and evolution of the universe. This theory suggests that the universe began as a singularity, which is a point of infinite mass and density. As the singularity expanded, it led to the creation of matter, energy, space, and time.
Mass, volume, and density are relevant in understanding the Big Bang theory. Initially, all the mass in the universe was concentrated in a single point of infinite density. As the universe expanded, this mass was spread out over a larger volume, resulting in a decrease in density. Understanding the concepts of mass, volume, and density helps us comprehend how the universe evolved from a highly concentrated state to its current diffuse state.
The key idea behind the Big Bang theory is that all the mass and energy in the universe were once concentrated in an extremely tiny region, and as the universe expanded, this concentration of mass and energy spread out resulting in the creation of galaxies, stars, and planets.
