Final answer:
The answer explains the expansion of the universe through Hubble's Law and cosmological redshift, as well as the basics of the Big Bang theory, dark energy, and dark matter.
Explanation:
Expansion of the Universe:
Hubble's Law: Hubble's law states that the velocity at which a distant galaxy is moving away from us is directly proportional to its distance. This provides evidence for an expanding universe.
Cosmological Redshift: Cosmological expansion results in the redshift of light from distant galaxies, indicating their movement away from us and supporting the idea of an expanding universe.
Big Bang Theory:
Formation: The Big Bang theory explains that the universe began as a singularity and has been expanding ever since, leading to the creation of all matter and energy we observe today.
Dark Energy and Dark Matter: Dark energy is the mysterious force driving the acceleration of this expansion, while dark matter is a form of matter that does not emit light but influences the dynamics of galaxies and cosmic structures.
