Big Bang

The Big Bang is the leading scientific theory for how the universe began. It is based upon the observation that the universe is expanding, and that the cosmic microwave background radiation is evenly distributed throughout the universe. These two observations suggest that the universe was once very hot and dense, and then expanded and cooled over time. The Big Bang theory is supported by a wide range of evidence, including the abundance of light elements in the universe, the large-scale structure of the universe, and the cosmic microwave background radiation.

What is the Big Bang theory?

The Big Bang theory is the leading scientific theory for how the universe began. It is based upon the observation that the universe is expanding, and that the cosmic microwave background radiation is evenly distributed throughout the universe. These two observations suggest that the universe was once very hot and dense, and then expanded and cooled over time.

The expansion of the universe

The expansion of the universe is one of the most important pieces of evidence for the Big Bang theory. The universe is expanding at an accelerating rate, and this expansion is consistent with the predictions of the Big Bang theory.

The cosmic microwave background radiation

The cosmic microwave background radiation is another important piece of evidence for the Big Bang theory. This radiation is a remnant of the early universe, and it is evenly distributed throughout the universe. The cosmic microwave background radiation provides strong evidence that the universe was once very hot and dense.

Why is the Big Bang theory important?

The Big Bang theory is important because it provides a scientific explanation for how the universe began. It is a well-supported theory that is consistent with a wide range of evidence. The Big Bang theory is a fundamental part of our understanding of the universe, and it has had a major impact on our understanding of our place in the cosmos.
