What came before the Big Bang is one of the biggest mysteries in science. In this video, we explore the theories that try to answer what existed before time, space, and the universe itself began.
From quantum fluctuations and cosmic cycles to multiverse ideas and eternal inflation, scientists are still debating whether the Big Bang was truly the beginning or just part of something much larger. Some theories suggest the universe had a past, others say time itself didn’t exist yet.
What came before the Big Bang challenges everything we think we know about reality, physics, and existence itself.
