Ep 8. The NEW Crisis in Cosmology

Description:

In PBS Space Time season 2021 episode 8, entitled "The NEW Crisis in Cosmology," viewers will delve deep into the world of cosmology - the science that studies the origins, evolution, and nature of the universe. The host of the show, Matt O'Dowd, will take viewers on a journey through the latest groundbreaking discoveries and explore the new challenges that scientists are facing in understanding our universe.

The show will begin by explaining the current state of cosmology, highlighting the most widely accepted models that have been used to explain the universe's origins and evolution. However, as the episode progresses, O'Dowd will explain how recent observations and discoveries are beginning to cast doubt on these models. The episode will explore new theories and ideas that are emerging as scientists try to reconcile this new data with the existing models.

One of the most significant challenges that cosmologists face is the discrepancy between two vastly different calculations of the universe's rate of expansion. Recently, a few different experiments have suggested that the universe is expanding much faster than scientists previously thought, which could have profound implications for our understanding of the universe's history. In this episode, viewers can expect to learn the full extent of this discrepancy and the efforts that scientists are making to resolve it.

The show will also discuss the Dark Energy problem, which is one of the most significant mysteries in cosmology. Dark Energy is a hypothetical form of energy that is thought to be responsible for the accelerating expansion of the universe. However, scientists have not yet been able to detect Dark Energy directly, and its properties remain largely unknown. In this episode, viewers will learn about the current state of Dark Energy research and the new ideas scientists are proposing to solve this mystery.

As the show progresses, viewers will also learn about some of the most fundamental questions in cosmology, such as, What is Dark Matter? Could there be an alternative explanation for it? And, what caused the Big Bang? PBS Space Time season 2021 episode 8 will explore all of these questions and more, providing a comprehensive look at the current state of the field.

Overall, "The NEW Crisis in Cosmology" promises to be an engaging and informative episode of PBS Space Time. Viewers will learn about the latest discoveries in cosmology, the efforts scientists are making to reconcile these discoveries with existing models, and some of the most fundamental questions in the field. Whether you're a seasoned science enthusiast or just starting to learn about the universe we live in, this episode is sure to provide a fascinating look into the cosmos.
