Suppose we have a curved spacetime with metric g, how can we find out the path of light throughout that space?

Thanks for reminding me ;) They are here for what it is worth.Ibix said:Edit: @m4r35n357 has written some simulations as well.
The "Path of Light in Curved Spacetime with Metric g" refers to the trajectory that light takes as it travels through a curved spacetime, where the metric g is used to describe the curvature of spacetime. This is a concept in the field of General Relativity, which explains how gravity affects the motion of objects in the universe.
The metric g is a mathematical tool used in General Relativity to describe the curvature of spacetime. It is a mathematical function that assigns a value to each point in spacetime, which represents the curvature at that point. By using the metric g, we can calculate the path that light will take as it travels through curved spacetime.
Understanding the Path of Light in Curved Spacetime is essential for understanding the behavior of light and other objects in the universe. It allows us to make accurate predictions about the motion of objects under the influence of gravity, such as planets orbiting around a star. It also plays a crucial role in many modern technologies, such as GPS systems, which rely on the principles of General Relativity.
In Flat Spacetime, the metric g is constant, and the path of light is a straight line. However, in Curved Spacetime, the metric g varies with the curvature of spacetime, causing the path of light to bend. This is due to the presence of massive objects, which create a curvature in spacetime, altering the trajectory of light.
One of the most well-known applications of the Path of Light in Curved Spacetime is in GPS systems, which use General Relativity to make precise calculations of location and time. Other applications include the study of black holes and the behavior of light around them, as well as the study of the expansion of the universe and the role of gravity in this process.
