Ep 1. How Big, How Far, How Fast

The Universe is an American television series that explores various topics related to astronomy, physics, and space exploration. In the seventh season's first episode of the show titled "How Big, How Far, How Fast," the experts delve deeper into some of the most intriguing mysteries of the universe.

The episode begins with presenting the question of how big our universe is and how far away various celestial bodies are from us. The experts discuss how vast the universe is and how it is impossible for humans to comprehend its size. They explain that the universe's size is continuously expanding, and hence, it is impossible to measure its exact size. However, the astronomers have been able to come up with an estimate of the size of the observable universe, which extends up to about 92 billion light-years.

The experts then move on to explore the vastness of space. They talk about how the closest star to our sun is about four light-years away from us, which means that it would take approximately four years for the light from that star to reach us. They also discuss how, in comparison, the Andromeda galaxy is a staggering 2.5 million light-years away, which means the light from that galaxy would take over two million years to reach us.

The episode then moves on to discuss some of the fastest-moving objects in the universe. The experts explain how light is the fastest thing in the universe, travelling at a speed of about 186,000 miles per second. They also discuss how some of the brightest stars in the universe are moving away from us at incredible speeds of over a million miles per hour.

The experts then talk about some of the latest discoveries in the field of astrophysics, which have helped them understand some of the universe's most significant mysteries. They discuss how scientists have discovered massive black holes that exist in the centers of galaxies, which can have a mass equal to over a billion times of our sun.

The episode also explores the concept of dark matter, which is an invisible material that scientists believe exists in the universe and holds galaxies together. The experts explain how scientists have been studying the effect of dark matter on galaxy movements, and the data they have collected has led them to conclude that dark matter makes up about 27% of the universe.

The episode concludes by summarizing that the universe's vastness is something that humans will never be able to entirely comprehend. However, through the latest discoveries in astrophysics, scientists have been able to gain a better understanding of the size, distance, and speed of some of the most significant objects in the universe, allowing us to gaze into the depths of the cosmos with greater clarity and awe.

The show's narrative is buoyed by an enthralling and visually stunning presentation with excellent production value. The experts provide a clear exposition that makes the episode accessible to newcomers and experts alike, leaving the audience spellbound and inspired. Overall, The Universe season 7 episode 1, "How Big, How Far, How Fast," is an exciting and illuminating offering that explores the fascinating mysteries of the cosmos and presents the latest scientific discoveries in a captivating and easily accessible manner.
