Gravitational Wave Successful Green Laser Pointer Detection

Gravity wave detection significance. The detection of gravitational waves has lasted for hundreds of years, so it has consumed huge human, material and financial resources. What is the significance of detecting gravitational waves? In fact, on the one hand, as an introduction to Einstein’s general theory of relativity, the existence of gravitational waves is an experimental verification of the actual facts recognized by Einstein’s theory of relativity. On the other hand, the laser pointer is understood from the perspective of space-time dimension.

At present, it is generally believed that three-dimensional space is actually not the case. There should be four-dimensional space, three-dimensional position space + one-dimensional space-time space. Simply put, time is also an important coordinate for describing matter. For example, we usually describe the location of an object as having three specific elements, the X axis, Y axis, and Z axis in the coordinate axis. This is in a short period of time, and what is described can be found through these three specific elements, but if the coordinates of these three spatial elements have not changed.

After a period of time, something has mildewed or changed its appearance. At this time, if there is no time coordinate, it will be difficult to describe this thing simply by using three-dimensional space coordinates. Therefore, on the basis of three-dimensional space, the successful green laser pointer detection of gravitational waves will open a new door to space and time for us.
