Scientists investigate the origins of the universe and the Big Bang theory

Scientists continue to explore the origins of the universe, focusing on the Big Bang, which occurred nearly 14 billion years ago. Evidence from Edwin Hubble's discovery of an expanding universe and the cosmic microwave background radiation supports this theory. Recent experiments at particle accelerators have revealed conditions close to the Big Bang, showing that the four fundamental forces of physics were once unified. As the universe expanded and cooled, these forces separated, leading to the formation of matter. Theories like cosmic inflation suggest that the universe underwent rapid expansion after the Big Bang, creating a uniform cosmos. However, what occurred before this inflation remains largely unknown, with some theories proposing chaotic conditions or singularities.
