The Big Bang is a type of beginning of the Universe. It wasn't exactly an explosion in the traditional sense, and it may or may not have been the actual beginning.We know about the Big Bang, among other things, because of the redshift of distant galaxies (the only reasonable explanation is that galaxies are moving away from us); because the element distribution in the Universe closely matches what is expected from a Big Bang; and because the cosmic microwave background radiation, likewise, closely matches the expectations.
The Big Bang
That is, more or less, the description of the Big Bang.
The Big Bang theory suggests that the universe began expanding from a very high-density and high-temperature state, but it was not an explosion in the traditional sense. It was a rapid expansion of space itself, not an explosion within preexisting space.
No, the Big Bang was not an explosion in the traditional sense. It was a rapid expansion of space and time that marked the beginning of the universe as we know it.
Astronomers believe the universe began with an explosion, known as the Big Bang, because of the observed expansion of the universe, the cosmic microwave background radiation, and the abundance of light elements like hydrogen and helium. These pieces of evidence support the idea that the universe started from an incredibly hot and dense state about 13.8 billion years ago.
big bang: This is the big bang theory
The best supporting information for the inference that the universe began with an explosion is the observation of the cosmic microwave background radiation, which is the afterglow of the Big Bang. Additionally, the redshift of distant galaxies indicates that the universe is expanding, suggesting it originated from a singular, explosive event. This evidence aligns with the Big Bang theory, which describes the universe's rapid expansion from an extremely hot and dense state.
actually it all started at a explosion called the big bang first the universe was stuck inside the explosion untill the universe began to expand inside this explosion pushing and making this explosion expand, finally when the explosion exploded the universe was formed
The theory that states the universe began in a violent explosion is the Big Bang theory. It proposes that the universe started as a singularity and has been expanding ever since, leading to the formation of galaxies, stars, and planets. This explosion occurred approximately 13.8 billion years ago.
The big bang theory which is a theory of cosmology holding that the expansion of the universe began with a gigantic explosion between 12 and 20 billion years ago
We do not know how the universe began, or what the exact sequence of events were.
That our Universe began with an explosion of matter, from a central point in space of high density to parts of space of low density. It was not an explosion at all, it was an expansion. And it wasn't of matter, it was of space itself.
