1. What evidence do we have for the Big Bang theory?

One of the main pieces of evidence for the Big Bang theory is the cosmic microwave background radiation, which is a remnant of the intense heat and energy released during the early stages of the universe's expansion. Other evidence includes the observed expansion of the universe, abundance of light elements, and the large-scale structure of the universe.

2. How do scientists study events before the Big Bang?

Currently, scientists use mathematical models and theoretical physics to study events before the Big Bang. These models, such as the inflationary model and cyclic model, propose different ways in which the universe could have existed before the Big Bang. However, due to the extreme conditions and lack of empirical evidence, it is still a subject of ongoing research and debate.

3. Can we ever know what caused the Big Bang?

Currently, we do not have enough evidence or understanding to determine the cause of the Big Bang. Some theories suggest that the universe has always existed and the Big Bang was just a moment of rapid expansion, while others propose that it was the result of a quantum fluctuation. It is a topic of ongoing research and ultimately, we may never be able to know for certain.

4. Has the Big Bang been proven?

The Big Bang theory is currently the most widely accepted explanation for the origins of the universe, but it has not been definitively proven. As with all scientific theories, it is subject to change as new evidence and discoveries are made. However, the vast amount of evidence supporting the Big Bang makes it a highly credible and well-supported theory.

5. What is the role of Cambridge University in studying the Big Bang?

Cambridge University, along with other universities and research institutions around the world, plays a crucial role in studying the Big Bang and the origins of the universe. Researchers at Cambridge use a variety of methods, such as theoretical physics, cosmology, and observational astronomy, to contribute to our understanding of the Big Bang and the early universe.
