How did scientists come up with the idea of the Big Bang?
The idea of the Big Bang originated from observations made by astronomers and physicists. In the early 20th century, scientists noticed that distant galaxies appeared to be moving away from us, which indicated that the universe was expanding. By tracing this expansion backward in time, they concluded that the universe must have started from an extremely hot and dense state, giving rise to the concept of the Big Bang. This theory has been supported by various pieces of evidence, such as the cosmic microwave background radiation and the abundance of light elements in the universe. So, thanks to the curious minds of scientists and their cosmic detective work, we now have the Big Bang theory to explain the origin and evolution of our universe. 🌌🔬
