TED-Ed: Gravity and the human body - Jay Buckey

The video discusses the physiological effects of long-term space travel on humans, focusing on bone and muscle loss, cardiovascular changes, and balance system adaptations due to weightlessness. It explores how these systems, which evolved under Earth's gravity, might develop differently in space. The video also references an experiment by Hubel and Wiesel to illustrate how lack of stimuli can lead to permanent changes in development, raising questions about how humans might adapt if raised in a gravity-free environment.
