Understanding the Universe's Fate

Michio Kaku discusses the expansion of the universe, explaining it through the Doppler shift, which affects light and sound. He describes how the universe's age is calculated by reversing its expansion to a single point, estimating it to be 13.7 billion years old. Kaku explores the universe's future, suggesting it may end in a 'big freeze' rather than a 'big crunch' due to its accelerating expansion. He speculates on the potential of intelligent life mastering Planck Energy to access parallel universes, offering a possible escape from the universe's eventual demise.
