The gravitational waves may provide
 a wealth of information about the Kingdom of God.

Our eyes use visible light to see things. At night, when there is no visible light, soldiers may use infrared to see enemy's activities. In hospitals, x-ray is commonly used to see possible symptoms inside our body. The visible light, infrared and x-ray are electromagnetic waves with different wavelengths. As explained in a previous article, electromagnetic waves (photons) are confined in our braneworld, which is a three-dimensional sub-universe embedded in a ten-dimensional bulk universe. If God is an intelligent life living outside our braneworld, it is impossible for us to see Him by electromagnetic waves.

The only possible way to see the Kingdom of God is by gravitational waves (gravitons), which also travel at the speed of light. The graviton can leave our braneworld and enter the bulk space. On the other hand, all kinds of particles can interact with gravitons. Therefore, it is possible to use gravitational waves to obtain information about the Kingdom of God. However, the gravitational waves are extremely weak compared to electromagnetic waves. This is because the gravitational waves are related to the gravitational force and the electromagnetic waves are related to the electromagnetic force. For the interaction between two electrons (which have both charge and mass), the electromagnetic force is 10⁴³ times stronger than the gravitational force. 

The gravitational waves are emitted when the motion of a mass is accelerating (including vibration and rotation), similar to the emission of electromagnetic waves from accelerating charges. Hence, it is very easy to generate a gravitational wave - just shake your head. However, to generate a detectable gravitational wave is a very challenging task. Although the gravitational wave was predicted by Einstein's general relativity in early 20th century, it has not been directly detected yet. The strongest gravitational wave may come from the rotation of stars. Currently, there are several gravitational wave observatories (e.g., LIGO and GEO 600) designed to detect gravitational waves from the space.

Because the graviton can go anywhere in the bulk universe and all kinds of particles can interact with the graviton, God is very likely to use gravitational waves to "see" our world. He may also use gravitons to influence our world, ranging from stellar motion, to biological evolution, and to our brain function. The existence of God will be confirmed if the gravitational waves from God are detected.

The most convincing way to prove the existence of God is to "see" God directly by gravitational waves. The classical method of vibration or rotation of a mass in our laboratory is unlikely to generate detectable gravitational waves. Recently, it has been suggested that the gravitational waves could be generated by quantum methods, similar to a laser that generates photon beams. The gravitational laser is called gaser (more info).

After a powerful gaser is developed, there is still another challenge: which direction should the gaser point to?  All directions that we can see with our eyes are in the braneworld, but God may be in the direction that is invisible to us. We do not have the answer at this time. However, since the gravitational waves may spread to the extra dimensions that cannot be seen by electromagnetic waves, the graviton beam may reveal the extra dimensions no matter which direction it is pointed to. After we gain more experience, we will be able to know how to probe the extra dimensions by gravitational waves. In the not-too-distant future, the gravitational waves may provide a wealth of information about the Kingdom of God.
