BIG BANG: The Birth of Everything? James Webb Is Forcing Scientists to Rethink! SPACETIME S08E01

The Big Bang marks the beginning of space, time and matter—but what actually happened in the first moments of our universe? This documentary explores the latest scientific understanding of the Big Bang, cosmic inflation, dark matter, dark energy, quantum physics and the formation of galaxies. Featuring insights from leading physicists and astrophysicists, it explains why the origin of the universe remains one of science's greatest mysteries. From the first fractions of a second to the discoveries of the James Webb Space Telescope, this documentary examines what we know, what remains uncertain and why the search for our cosmic origins continues.

What is the Big Bang theory?
The Big Bang theory is the leading scientific explanation for the origin of the universe. It proposes that space, time, matter and energy began approximately 13.8 billion years ago in an extremely hot, dense state before expanding rapidly. The theory is supported by observations such as the expansion of the universe and the cosmic microwave background radiation.
What happened before the Big Bang?
Scientists currently have no definitive answer to what existed before the Big Bang. Since space and time themselves are believed to have originated with the Big Bang, the concept of "before" may not apply in the conventional sense. Several hypotheses—including quantum gravity, cyclic universes and the multiverse—are being explored, but none has yet been confirmed.
How does the James Webb Space Telescope challenge the Big Bang theory?
The James Webb Space Telescope has discovered surprisingly massive and well-developed galaxies that formed only a few hundred million years after the Big Bang. Rather than disproving the Big Bang, these observations suggest that galaxy formation occurred much faster than previously expected and may require refinements to existing cosmological models.
