Artificial gravity is transitioning from science fiction to practical engineering reality, with rotating habitats and centrifuge research advancing rapidly to solve the devastating health effects of long-term spaceflight on human physiology.
Scientists are decoding hibernation mechanisms—metabolic suppression, mitochondrial protection, antifreeze proteins—to develop human suspended animation. Already, therapeutic hypothermia saves newborns and organ preservation techniques extend transplant windows. Within a decade, trauma patients may be placed on ice to buy surgical time, and astronauts could hibernate on Mars missions. Yet challenges abound: physiological risks, inequality in access, regulatory hurdles, and ethical dilemmas ab...
