Young Sheldon Season 6, Episode 4 Has Fans All Buzzing About The 'Zero' Scene

Contains spoilers for "Young Sheldon" Season 6, Episode 4

The intelligence of the titular character on "Young Sheldon" allows viewers to dive deeper into mathematical and scientific concepts. This is a precedent set by the original series, "The Big Bang Theory," on which Sheldon (Jim Parsons) and his friends are all experts in their respective fields. This authentic pursuit of knowledge also opened the show up for a wide array of guest stars, including world-renowned scientists like Neil deGrasse Tyson and Stephen Hawking.

On "Young Sheldon," Sheldon's (Iain Armitage) intellect propels him into college at an early age. This is where he meets the professors who inspire his future career: Dr. John Sturgis (Wallace Shawn) and Dr. Linkletter (Ed Begley Jr.). These two match Sheldon's intelligence and often challenge his previous notions, leading to the hilarious problem-solving in Season 6, Episode 4, "Blonde Ambition and the Concept of Zero."

While Sheldon is tutoring his next-door neighbor Billy (Wyatt McClure) in math, he's faced with an Earth-shattering question: An entity cannot be both something and nothing, so does zero really exist? The mind-blowing conundrum was met with an exciting amount of fan response on both Twitter and Reddit.

Fans praise the episode as one of their all-time favorites

Without zero, mathematics would simply fall apart, leading Sheldon to an overexaggerated existential crisis. This comical moment had fans in stitches sharing their favorite moments online. Redditor u/termacct dubbed the episode one of their favorites, saying, "I really loved the zero conundrum – this might be my most fave YS episode." Redditor u/MandoAviator sparked their own scientific debate, commenting, "If a car is not moving, its speed is zero. Boom."

The Twittersphere was equally enthralled and stupefied by the possible nonexistence of zero. "Sheldon: Zero isn't real!!! Trashcan [sic] Barfs. Sturgis: Zero isn't real!!! Trashcan [sic] Screams. Linkletter: Zero isn't real!!! Hand over the [t]rashcan [sic]," tweeted @tvcriticme, breaking down the episode's most hysterical scene, in which the three scientists are so uneasy at this suggestion that it causes them to sequentially lose their lunches by hurling into the trash bin. Another user, @jayel1964, praised Billy as the unexpected source of inspiration that kicks off the entertaining and overly dramatic ordeal, tweeting, "Yay, Billy! He scored one by proving zero doesn't exist!"
