In this passage, we will study space-time, ricci tensor, and minkowski topology.
Minkowski is a well-known German Mathematician who lives in the time of Albert Einstein. He is pretty friendly with the work of Einstein on explaining space-time curvature. He is a professor of Albert Einstein, in 21 September 1908, he delivered, alongside Einstein works, the meaning of space-time in Special Relativity and General Relativity, on the 80th Assembly of German Natural Scientists and Physician.
"The views of space and time which I wish to lay before you have sprung from the soil of experimental physics, and therein lies their strength. They are radical. Henceforth space by itself, and time by itself, are doomed to fade away into mere shadows, and only a kind of union of the two will preserve an independent reality."
Even if they still use the cartesian diagram to profoundly map relativity, yet the Euclidian did not falter too much from the tensor mathematics and topology. In short, as a starting, let's imagine two places in space-time, one started in New York City, and say the other one started in Bandung. Accordingly, let's say the distance is stated in two dimensions, in which started in New York City was 1000 years ago even before the city was built, while the one in Bandung started just several years ago. According to time reference, these two states were differentiated by the fourth dimension, especially close frame of reference yet quite different as long as quaternion has to comply. So, the t on the first state equation is say 1000 and the second t let's commute with r is 3. let's say that the equation is
S2 = x2 + c2t2
and
S2 = x2 + c2r2
We can see that the delta S of the component would include two different time measures, in which were 1000 as t and 3 as r. As how we see it, then S would propagate either as the square root of the first as well as the second equation. To solve this equation and knows the real dimension of the planar, we would use the equation in differentiation to solve on each slopes and points.
