This advanced technology is developed in the field of measurement, at the atomic level, the degree of change in ambient gravity , as well as for the detection of gravitational waves - ripples sort of space-time, which is caused by various events, including the Big Bang. According to the general theory of relativity, Albert Einstein created; gravitational waves are provided when massive cosmic bodies, during its motion, break the fabric of space and time.
However, by the time when these gravitational waves reach the Earth, they are already extremely weak and detect their presence is only possible to observe the atoms. It is precisely because of this, even when using the most advanced ground-based interferometers; "see" gravity waves is not possible.
Experts believe NASA; of an atom interferometer could easily solve this problem and give astronomers a tool to study a variety of phenomena. For example, thanks to this tool, it will be possible to study black holes.
The principle of atom interferometer based on the same principle that is running and optical instruments - is a comparison of the two beams of light. However, it is more dependent on the quantum mechanics, in particular the effect on the cool-down to absolute zero, at which they can be placed in a state of superposition and be distributed across different trajectories. This is what will create the atomic interferometer, which fact, be an optical analogue, but it is much more accurate.
Now, scientists have developed a powerful narrowband optical fiber laser system, the test to be held at one of the largest interferometer, which is located at the laboratory of physics at Stanford University.
