Step 1:I'll solve this problem by providing a detailed explanation about the highest G-forces survived by a human.
Step 2:: Understanding G-Forces
One G is equivalent to Earth's gravitational acceleration, approximately $$9.8 \mathrm{m/s}^{2}$$.
G-forces represent the acceleration experienced relative to gravitational acceleration.
Step 3:: Record Holder
The highest documented G-force survived by a human is $$46 \mathrm{G}$$, experienced by Colonel John Stapp during a rocket sled deceleration test in 1954.
Step 4:: Context of the Experiment
Stapp was part of the U. S. Air Force's research into human tolerance for extreme acceleration and deceleration. He deliberately subjected himself to extreme G-forces to understand human physiological limits.
Step 5:: Specific Details of the Test
- Location: Holloman Air Force Base, New Mexico - Date: December 10, 1954 - Duration of extreme G-force: Extremely brief (less than one second) - Purpose: Understanding human survivability in high-speed emergency scenarios
Step 6:: Physiological Impact
At $$46 \mathrm{G}$$, Stapp experienced:
- Temporary blindness - Severe physical strain - Potential risk of fatal injury - Significant medical research contribution
Final Answer
The highest G-force survived by a human is 46 \mathrm{G}, achieved by Colonel John Stapp in a controlled scientific experiment in 1954.
