Cosmology Explained: The Science of the Universe’s Origin

Cosmology is the branch of science that studies the universe’s birth, structure, and ultimate fate.
The Big Bang Theory is the leading model, describing the universe’s beginning 13.8 billion years ago.
Cosmic microwave background radiation is the afterglow of the Big Bang, a fingerprint of the early cosmos.
Cosmologists investigate dark matter, an invisible mass shaping galaxies and cosmic structure.
Dark energy drives the accelerating expansion of the universe, a discovery that reshaped modern science.
Observations of distant galaxies reveal that the universe is expanding, first discovered by Edwin Hubble.
Inflation theory proposes a burst of rapid expansion just fractions of a second after the Big Bang.
Cosmology uses data from telescopes, satellites, and particle accelerators to piece together cosmic history.
By studying large-scale structures, cosmologists map the web of galaxies across billions of light-years.
Cosmology bridges physics and philosophy, tackling ultimate questions of existence and the universe’s destiny.
