So, how does Hubble's Law support the Big Bang Theory? Well, if the universe is still expanding, it means that everything was once really, really close together. This idea is the foundation of the Big Bang Theory, which says that the universe began as a single point and has been expanding ever since. It's like the ultimate cosmic explosion!
The Big Bang Theory is supported by a ton of other evidence, including cosmic microwave background radiation and the abundance of light elements in the universe. It's pretty cool to think that we can learn about the birth of the universe just by looking at the clues that are all around us. The universe is like a big mystery novel, and scientists are still trying to figure out the ending!
