Have you ever wondered how many G's it would take to knock you out? It's a question that has been asked by thrill seekers, fighter pilots, and astronauts alike. Well, the answer may surprise you. The truth is that it depends on a variety of factors like your physical condition, the type of G-forces you experience, and the duration of the exposure. Generally speaking though, it takes exposure to more than 5 G's for most people to feel the effects of being knocked out. So, the next time you find yourself in an intense situation, remember that it may take more than five G's to knock you out.
