In 2001, he graduated at the top of his class with a degree in physics from Kent State University and began to pursue a graduate degree in biophysics. Arthur became involved in local politics and now serves as chairman of the Ashtabula County board of elections. His wife, Sarah Fowler Arthur has represented Ohio's 99th district in the Ohio state legislature since 2021. Arthur enlisted in the US Army in 2003 and was deployed to Iraq from 2005 to 2007.

Science & Futurism with Isaac Arthur
Arthur began the educational YouTube channel Science & Futurism with Isaac Arthur in 2012. In September 2014, he released the first video on the channel on the topic of megastructures. As of March 7, 2023, the channel has over subscribers and  videos.

Arthur joined the United States Air Force Academy space policy course as a visiting lecturer, contributed to the academy's simultaneous transition to remote education during the COVID-19 pandemic and the launch of the graduation of USAFA cadets into the United States Space Force.

Arthur serves on his hometown board of elections by day, spending the majority of his personal time working on production of his videos. He collaborates with other science communicators, including Paul Sutter and Fraser Cain, and acts as an analyst and consultant for science fiction novels and games, such as HADES 9. His channel is dedicated to topics including space colonization in the near and far future, futurism, artificial intelligence, and transhumanism, among others, especially in the context of thermodynamics, economics, science fiction, the Fermi paradox, and the Dyson dilemma. The channel's main focus is to speculate on how humanity or other hypothetical advanced civilizations may behave logistically, technologically, and socially, in the near and distant future under the laws of known science.

The channel releases new episodes every Thursday, which tend to be around thirty minutes in length and are roughly organized into series:


 * Advanced Civilizations
 * Alien Civilizations
 * Post Scarcity Civilizations
 * Civilizations at the End of Time
 * Cyborgs, Androids, Transhumanism & AI
 * Fermi Paradox
 * Interstellar Warfare
 * Megastructures
 * Upward Bound
 * Outward Bound

Outward Bound's main protagonist is the traveler, featured across the series.

Arthur collaborates with other YouTubers and science communicators.
