This paper - http://arxiv.org/abs/1211.3816 - by Beckenstein is fascinating. I would like to know if the experimental test proposal is realistic.
I would expect mainly hydrogen in the vacuum, as it can diffuse through other materials easily. It is the dominant contribution in the LHC vacuum, for example.But I suspect that you might be dealing with a lot of high-molecular-mass gunk such as finger grease or stuff that outgasses from various surfaces, which also might be high in molecular mass.
If the accelerations are slow, it might not matter.I think the general assumption there that photon transmission depends on the displacement is very speculative, even if that displacement is of the order of the Planck length.Hasn't he simply designed the world's most sensitive seismometer?

A tabletop search for Planck scale signals is a scientific research method that involves using laboratory equipment, such as lasers and detectors, to search for signals that may indicate the existence of the Planck scale. The Planck scale is the smallest scale at which the laws of physics can be applied and is a crucial concept in theories of quantum gravity.
Searching for Planck scale signals is important because it can help us better understand the fundamental laws of physics and potentially lead to the development of a theory of quantum gravity. It can also provide insights into the nature of space, time, and matter at the smallest scales.
Currently, a tabletop search for Planck scale signals is not feasible due to technological limitations. The required energy and precision to detect these signals are beyond the capabilities of current laboratory equipment. However, with advancements in technology, it may become more feasible in the future.
One of the main challenges in conducting a tabletop search for Planck scale signals is the extremely small scales involved. The Planck scale is about 10^-35 meters, which is much smaller than current experimental capabilities. Another challenge is the high energy required to produce and detect these signals, which may not be attainable with current technology.
A successful tabletop search for Planck scale signals could have significant implications for our understanding of the universe. It could provide evidence for the existence of the Planck scale and help bridge the gap between quantum mechanics and general relativity. It could also potentially lead to new technologies and advancements in our understanding of the fundamental laws of physics.
