    The dude has a masters in physics. I’m pretty sure he did the math and that that’s enough to kill a man.

    It will drain the blood completely out of your brain until it stops functioning permanently. It will also cause irreparable trauma to your organs.

    That’s what the smaller circles are for. You need to see it in 3D, the loops aren’t linear, they will trail off into a spiral, away from the “viewer” (or towards, depending which side you choose to see it from).

    It’s sustained 10G over 60 seconds, through seven inversions.

    It’ll kill you for sure.

      Just because you are a master of physics does not mean you are a master of physiology…

      It will drain the blood completely out of your brain until it stops functioning permanently. It will also cause irreparable trauma to your organs.

      10G is not enough to completely drain your brain of blood, nor is it enough to cause irreparable harm to your organs for a healthy adult.

      For positive or upward g force we are pretty tolerant, though you will definitely G-loc, but G-loc isn’t really that harmful if it isn’t something that’s happening frequently.

      “The human body is flexible and deformable, particularly the softer tissues. A hard slap on the face may briefly impose hundreds of g locally but not produce any real damage; a constant 16 g for a minute, however, may be deadly.”

      For negative vertical g force we are much less tolerant, and is much more damaging to the body. That is when blood is forced to your head instead of you feet.

      “Resistance to “negative” or “downward” g, which drives blood to the head, is much lower. This limit is typically in the −2 to −3 g0 (−20 to −29 m/s2) range. This condition is sometimes referred to as red out where vision is literally reddened[11] due to the blood-laden lower eyelid being pulled into the field of vision.[12] Negative g-force is generally unpleasant and can cause damage. Blood vessels in the eyes or brain may swell or burst under the increased blood pressure, resulting in degraded sight or even blindness.”

      For horizontal g forces we are quite tolerant.

      “Early experiments showed that untrained humans were able to tolerate a range of accelerations depending on the time of exposure. This ranged from as much as 20 g for less than 10 seconds, to 10 g for 1 minute, and 6 g0 for 10 minutes for both eyeballs in and out. These forces were endured with cognitive facilities intact, as subjects were able to perform simple physical and communication tasks. The tests were determined not to cause long- or short-term harm although tolerance was quite subjective, with only the most motivated non-pilots capable of completing tests”

      My father used to teach aeronautical physiology when he was in the Air Force and then for FAA when he retired from the military. He operated the centrifuge at Holloman AFB for 5 years when we were stationed in New Mexico. Sustained 10g won’t be fun, and you will probably G-loc and shit your pants, but it wouldn’t kill the average person unless they were negative gs, and that isnt happening from hypoxia, nor isn’t a pleasant or fun way to go.
