What Would Happen To An Astronaut Who Felt No Gravity In Orbit?

💡 The Answer

• Astronauts in orbit are not truly weightless; they are in free fall around Earth.
• The feeling of weightlessness comes from the absence of the normal reaction force against gravity.
• Microgravity causes fluid shifts upward, leading to puffy faces and thinner legs.
• Bones and muscles weaken without the constant pull of gravity to work against.
