If the turbulence will be 'extreme' (lets assume a fluctuation of 2gs), we will reach a max positive G load of 3g and a negative G load of -1g. Perhaps that’ll be some solace the next time you take a tumble, when gravity grabs your attention too. So assuming a fluctuation of 1g (positive or negative) inside turbulence, we can assume that we will be able to reach +2.0g or -0g passing trough this turbulence.
It seems that, from the smallest scale to the largest, gravity keeps attracting scientists’ attention. Others have looked at creative ways to magnify quantum gravity effects, using vibrations in a large metal bar or collections of atoms kept at ultracold temperatures. Some people have proposed theories that would let quantum gravity show up at close to the millimeter scale, but so far we haven’t seen those effects. When pulling intense G-forces, its common for people to experience a temporary loss of consciousness called G-LOC. That’s where quantum gravity’s effects will be strong enough to measure, but it’s far too small for any experiment to probe. Ultimately, it reaches the strength of the other forces at a very tiny distance known as the Planck length, many times smaller than the nucleus of an atom. Gravity is very weak, but the closer together two objects are, the stronger it becomes. Quantum gravity appears at the smallest length anything can be. On Earth, the acceleration of gravity generally has a value of 9.806 m/s2 or 32.1740 f/s2. Gravity is measured in metres per second squared, or m/s2. It’s what keeps our feet firmly planted on the ground. Illustration by Sandbox Studio, Chicago with Ana Kova 6. 1G is the acceleration we feel due to the force of gravity. Neither loop quantum gravity nor string theory, nor any other theory is currently able to provide testable details about the microscopic behavior of gravity. This allows loop quantum gravity to describe the effect of gravity on a scale far smaller than the nucleus of an atom.Ī more famous approach is string theory, where particles-including gravitons-are considered to be vibrations of strings that are coiled up in dimensions too small for experiments to reach. Matter would be restricted to hopping from one point to another on a flexible, mesh-like structure. It proposes that space-time is particle-like on the tiniest scales, the same way matter is made of particles. One G never felt so welcomegood old 32 feet per second squared. One avenue of research is called loop quantum gravity, which uses techniques from quantum physics to describe the structure of space-time. However, we still don’t have a fully working quantum theory of gravity, though researchers are trying. The other three fundamental forces of nature are described by quantum theories at the smallest of scales- specifically, the Standard Model. Explaining the microscopic behavior of gravity has thrown researchers for a loop.
