Ballium's number is a number coined in a parody YouTube video by Meerkats Anonymous, in which a fictional physicist Samuel Ballium claims it to be "the largest number."According to the video, Ballium's number is exactly \[(794{,}843{,}294{,}078{,}147{,}843{,}293.7 + 1/30) \cdot e^{\pi^{e^\pi}}\] In the video, a spoof on newscasts about scientific findings, Ballium explains how he accidentally added "Hamlet" to an equation he was working on and stumbled upon this number. The video also goes on to say that the "Microsoft calculator struggles to produce an output, even when set to scientific mode." ∎
