The main Vsauce channel, also known as Vsauce1 to distinguish it from the series as a whole and the other channels, is hosted by the founder, Michael Stevens, and dedicated for a mix of philosophical and scientific questions about the universe and its contents (including humans). The primary segment, DOT, questions things such as "Is anything real?", "What if everyone jumped at once?", "How much does the Internet weigh?", "How old can we get?", or "How big can a human get?". WOAH is another segment which details hypothetical events and "what would occur if it actually happened?" Stevens has stated he researches on Wikipedia and academic papers to find information for his videos.
