“It’s not something that we normally experience on Earth unless you’re sort of standing on your hands.” “The blood that normally pools in the extremities redistributes toward the head,” Kramer told.
Kramer theorizes that a lack of gravity in space causes blood to rush to the head instead of circulating throughout the body. Furthermore, Kramer found that these changes could persist a year after the subject had returned from space and may even be long-lasting issues, although the radiologist admitted that more study was needed.
After running MRIs on 11 astronauts before and after space travel, Kramer and his team found that prolonged exposure to microgravity and the resulting intracranial pressure could cause the brain to swell as well as change the volume of cerebrospinal fluid and the shape of the pituitary gland. Larry Kramer, a radiologist at the University of Texas Health Science Center at Houston, has found that intracranial pressure may also cause changes in the brain. Now, the new study by the RSNA, led by Dr. “Scientists suspect that these vision issues are caused by increased ‘intracranial pressure,’ or pressure in the head, during spaceflight.” “Medical evaluations on Earth have revealed that astronauts’ optic nerves swell and some experience retinal hemorrhage and other structural changes to their eyes,” ‘s Chelsea Gohd writes. As notes in its own report on the study, there have also been many recorded cases of astronauts suffering from issues with their eyesight after returning from space. This isn’t the first time that doctors and scientists have encountered changes to human physiology in astronauts, including cases of muscle atrophy and the deterioration of a subject’s skeleton. The Radiological Society of North America (RSNA) released a study in April 2020 that shows how the human brain could be affected by prolonged exposure to microgravity in a spacecraft.
In fact, according to a new scientific study, 2001 may have predicted yet another aspect of space travel researchers are only beginning to understand.
Space odyssey movie#
Today, the movie is recognized for its predictive power. Decades later, the story of how man was born and reached the stars still feels like more than just a space-faring fairy tale. Clarke and Stanley Kubrick’s 2001: A Space Odyssey is regarded today as one of the most influential and important pieces of science fiction ever made.
