The Shortest Year In The Universe

The video explores the concept of time across the universe, highlighting the differences in year lengths on various celestial bodies. It begins with Mercury's short year and long day, then discusses how exoplanets are detected, often having short years due to their proximity to stars. The video also covers the shortest known year around a pulsar and a main sequence star, and concludes with the longest planetary year and the concept of a galactic year, emphasizing the vastness of time in space.
