Jun 18, 2024 · Big-bang model, widely held theory of the evolution of the universe. Its essential feature is the emergence of the universe from a state of extremely high temperature and density—the so-called big bang that occurred 13.8 billion years ago.
The Big Bang is a physical theory that describes how the universe expanded from an initial state of high density and temperature. [1] . It was first proposed as a physical theory in 1931 by Roman Catholic priest and physicist Georges Lemaître when he suggested the universe emerged from a "primeval atom".
The origin, evolution, and nature of the universe have fascinated and confounded humankind for centuries. New ideas and major discoveries made during the 20th century transformed cosmology – the term for the way we conceptualize and study the universe – although much remains unknown. Learn more.
Jul 9, 2024 · The big bang is how astronomers explain the way the universe began. It is the idea that the universe began as just a single point, then expanded and stretched to grow as large as it is right now—and it is still stretching!
Jan 18, 2017 · The most popular theory of our universe's origin centers on a cosmic cataclysm unmatched in all of history—the big bang. Learn about the big bang theory and how our universe got...
Physicists are even starting to tackle the big gaping holes in the big bang theory: what came before the big bang? What triggered it? How will the universe end?
Feb 2, 2022 · The Big Bang was not an explosion in space, as the theory's name might suggest. Instead, it was the appearance of space everywhere in the universe, researchers have said.
Hubble’s discovery was the first observational support for Georges Lemaître’s Big Bang theory of the universe, proposed in 1927. Lemaître proposed that the universe expanded explosively from an extremely dense and hot state, and continues to expand today.
Oct 11, 2017 · The concept of the Big Bang is easy to misunderstand. In this Q&A, Dr. John Mather, a Nobel laureate and the senior project scientist for NASA’s James Webb Space Telescope, answers some commonly asked questions about this expanding universe story, and about Webb’s role in understanding the early history of the universe.
