There is perhaps no room for science when we talk about religion and vice-versa. However, there is one religion whose cosmological beliefs sit well with the current model of the Universe.
Aug 16, 2024 · August 16, 2024. The best-supported theory of our universe's origin centers on an event known as the big bang. This theory was born of the observation that other galaxies are moving away from our ...
- How it all started. 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.
- The universe's first growth spurt. When the universe was very young — something like a hundredth of a billionth of a trillionth of a trillionth of a second (whew!)
- Too hot to shine. Light chemical elements were created within the first three minutes of the universe's formation. As the universe expanded, temperatures cooled and protons and neutrons collided to make deuterium, which is an isotope of hydrogen.
- Let there be light. About 380,000 years after the Big Bang, matter cooled enough for electrons to combine with nuclei to form neutral atoms. This phase is known as "recombination," and the absorption of free electrons caused the universe to become transparent.
Aug 22, 2024 · The big-bang theory proposes that the universe was formed from an infinitely dense and hot material core. The bang in the title suggests there was an explosive, outward expansion of all matter and space that created atoms. Spectroscopy confirms that hydrogen makes up about 74% of all matter in the universe.
The Universe’s History 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. Here is the history of the universe according […]
The Origin of the Universe according to the Big Bang Theory. The Big Bang Theory says that our known universe originated from a singularity—an infinitely small and dense point—approximately 13.8 billion years ago. This theory suggests that all matter, energy, and the fabric of space itself were compressed into this singularity before ...

The universe is everything. It includes all of space, and all the matter and energy that space contains. It even includes time itself and, of course, it includes you. Earth and the Moon are part of the universe, as are the other planets and their many dozens of moons. Along with asteroids and comets, the planets orbit the Sun.
