Brian Cox - What Caused The Big Bang? Ever pondered the enigma of the universe's inception? Join Brian Cox and Brian Greene in a captivating exploration of the Big Bang's mysteries. This journey takes us 14 billion years back, to a time when all matter and energy were compressed into an infinitesimal point, destined to expand and create the cosmos we know today. This video delves into the depths of cosmology, challenging the boundaries of our understanding of physics. Discover the nuances of time's creation, the nature of the universe at T equals 0, and the emergence of time and space as we comprehend them. We examine the universe's expansion and cooling, leading to the formation of the first particles and atoms, culminating in the cosmic microwave background radiation – a testament to this colossal event. But the intrigue deepens. What existed at T equals 0? Was there a 'before' the Big Bang? Our experts analyze theories like quantum fluctuations, where the vacuum of space teems with energy, potentially sparking the Big Bang. The multiverse theory, string theory's branes collision, and cosmic inflation are also scrutinized, offering diverse perspectives on our universe's birth. This video isn't just about seeking answers but understanding the questions themselves. We shift from asking 'why' to probing 'how' – how conditions aligned for the universe's birth, how physical laws and randomness intertwined to birth our cosmos. Dive into a universe so dense that it's beyond imagination, where concepts like 'repulsive gravity' challenge our very understanding of cosmic forces. This journey through the Big Bang's aftermath isn't just a scientific exploration; it's an invitation to marvel at the cosmos's vast complexities and mysteries Subscribe to Science Time: null #briancox #briangreene #bigbang
