A prototype atom interferometer chip in a vacuum chamber, harnessing the quantum behaviour of atoms to perform ultra-precise measurements of gravity.

"Quantum physics and space travel are two of the greatest scientific achievements of the last century," comments ESA's Bruno Leone, who this month organised the latest Agency workshop on technologies.

"We now see huge great promise in bringing them together: many quantum experiments can be performed much more precisely in space, away from terrestrial perturbations. In addition, the new generation of quantum devices offer huge improvements to space-related technology.

"Potential is there for the use of in areas such as Earth observation, planetary exploration, secure communications, fundamental physics, microgravity research and navigation."

This Earth gravity meter is being developed by RAL Space in the UK and IQO Hannover in Germany, with ESA support.

Microwave and light interferometers provide extremely precise measurements by combining different waves. Just like sets of ripples meeting in water, the combination of slightly different signals creates interference patterns.

This interferometer takes advantage of the fact that – as stated by quantum theory – atoms also behave like waves as well as particles, and can be combined to deliver extraordinary atomic-scale precision. It could be used in principle to map variations in Earth's gravity with orders of magnitude greater than our current best.

Technology is finally learning from natures rules of how and why gravity works.

The principles of atomic gravity are a description of how gravity works at the atomic scale. The principles are fundamental in the natural world.

The academics behind the research presented in the above article should be first in line to explore all solutions. Words like maybe, possibly or hopefully are not an effective part of the scientific method.

Academia's current teachings that gravity is a geometric construct, not a force has really inhibited innovation and discovery in this area of research.

A similar academic situation occurred during the time of Galileo when academia taught that the Earth was the center of the universe.

The answers begin by understanding how gravity works at the atomic scale. The principles of atomic gravity are simple and have been proven over and over again.
