Yes that is truth. But I am wondering if a force that is very strong, could it change the space but does not change the laser or light? like squeeze it or extend it..Scott said:
In the extreme, the EM field has a mass and therefor gravity. And of course, it would warp space as gravity does. But unless you EM field is powered by fusion bombs, your body would cause more space warping than that EM field.sidabao said:
That is great point, thank you..Scott said:
A gravity wave is a disturbance in the fabric of spacetime caused by the acceleration of massive objects.
Gravity waves can be measured using a variety of instruments, such as laser interferometers, which detect tiny changes in the distance between two objects caused by the passing of a gravity wave.
Measuring gravity waves can help us better understand the universe, as they can provide information about massive objects such as black holes and neutron stars. It can also help us test and refine theories of gravity.
Relative measurement in the context of gravity waves refers to measuring the changes in distance between two objects caused by the passing of a gravity wave. This allows us to detect and study these waves, even though they are incredibly small and difficult to detect directly.
Measuring gravity waves is a difficult task, as the waves are very weak and can easily be masked by background noise. Scientists also face challenges in building sensitive enough instruments and techniques to detect these tiny changes in distance.
