The Answer:
And, the answer for the the question is :
Explanation:
Edwin Hubble, an astronomer, demonstrated in 1924 that the cosmos was expanding and that the rate of expansion increased with increasing distance. These findings provide credence to the Big Bang theory of cosmology, which proposes that the universe expanded swiftly from a tiny, dense state to the vast expanse we see today.
The Big Bang theory is one of the most widely accepted explanations for the origins of the universe. It proposes that the universe began as a tiny, hot, and incredibly dense point, and has been expanding ever since. One of the key pieces of evidence for this theory is the discovery that the universe is expanding.
The idea that the universe is expanding was first proposed in the 1920s by the American astronomer Edwin Hubble. Hubble observed that distant galaxies were moving away from us, and that the farther away a galaxy was, the faster it was moving. This observation suggested that the universe was expanding, and that the galaxies were moving away from each other as the universe expanded.
This discovery was a major breakthrough in our understanding of the universe. It provided evidence that the universe had a beginning, and that it has been expanding ever since. It also supported the idea that the universe was much smaller and hotter in the past, as predicted by the Big Bang theory.
The Big Bang theory proposes that the universe began as a singularity, a point of infinite density and temperature. This singularity then expanded rapidly in a process known as inflation, which lasted for a fraction of a second. As the universe expanded, it cooled and matter began to form, eventually leading to the formation of galaxies and stars.
The discovery that the universe is expanding provided strong evidence for the Big Bang theory, as it supported the idea that the universe had a beginning and has been expanding ever since. However, there are still many questions that remain unanswered, such as what caused the initial singularity and what happened in the first moments of the universe.
astronomers continue to study the expansion of the universe using a variety of techniques, such as measuring the distances and velocities of galaxies and observing the cosmic microwave background radiation. These observations have provided further evidence for the Big Bang theory and have helped to refine our understanding of the universe.
the discovery that the universe is expanding is a key piece of evidence for the Big Bang theory. It provides strong support for the idea that the universe had a beginning and has been expanding ever since. While there are still many mysteries and unanswered questions surrounding the origins of the universe, the Big Bang theory remains one of the most widely accepted explanations for how the universe came to be.
