A weightless vacuum container, when floated in the atmosphere, theoretically has no maximum height due to the continuous displacement of atmospheric weight. The principle of buoyancy, as described by Archimedes, suggests that the container would experience an outward force from pressure differences on its sides. In reality, high-altitude balloon flights demonstrate a practical limit of around 50 kilometers, although this does not apply to a truly weightless scenario. The discussion highlights the contrast between theoretical physics and practical limitations in atmospheric conditions. Ultimately, the concept remains a thought experiment with intriguing implications for buoyancy and pressure.
