what is the big bang، The Big Bang is how astronomers explain the way the universe began. It’s the idea that the universe started out as just one point, then expanded and expanded to grow to the size it is now – and is still expanding! why all that? In 1927 an astronomer named Georges Lemaître had an idea.
what is the big bang theory
The Big Bang event is a physical theory that describes how the universe expanded from an initial state of high density and temperature. Different cosmological models of the Big Bang explain the evolution of the observable universe from the earliest known periods through its later, large-scale form.
The Big Bang model, the popular theory of the evolution of the universe. Its main feature is that the universe emerged from a state of extreme high temperature and density – the so-called Big Bang that occurred 13.8 billion years ago.
how did the big bang happen
The Big Bang theory was thought about nearly 100 years ago. It has been accepted by scientists and the public as the origin of the universe for more than 50 years. However, it still holds many mysteries. Most of it revolves around the fact that what we see does not match what the theory tells us. If we go by the evidence, about 95% of the universe is invisible.
That moment was the Big Bang. We can even tell when that happened from the speed of the galaxies: about 14 billion years ago. We can’t actually see the galaxies moving, but the evidence lies in.
what is the big bang theory science
The Big Bang is a really misleading name for the expanding universe that we see. We see the infinite universe expanding in on itself. The name Big Bang conveys the idea of exploding fireworks at a time and place – with a center. The universe has no center. It happened everywhere at once and it was a process that happened in time.

what is cosmic microwave background
amazing! This brilliant idea later became known as the Big Bang! The Big Bang was the moment 13.8 billion years ago when the universe began as a small, dense fireball that exploded. Most astronomers use the theory to explain how the universe began. But what caused this explosion in the first place remains a mystery.
The universe did not exist forever. I was born. About 13.82 billion years ago, matter, energy, space and time erupted in a fireball called the Big Bang. It expanded, and from the cold wreckage were frozen galaxies – islands of stars of which our Milky Way is one in two trillion. This is the theory.

The Big Bang is generally believed to be the beginning of everything: about 13.8 billion years ago, the visible universe boomed and expanded into existence.
