What is the mathematical reasoning, for reducing GR down to the quantum world? How would these application be considered in a supersymmetrical world?
Is the figure-eight knot the same knot as its mirror-image? The property of "being the same as your mirror-image" is called chirality by knot theorists. The image sequence below shows the figure-eight knot being transformed into its mirror image -- such knots are called achiral
You have to remember this is the year 2000, article was produced below.
Physicists Finally Find a Way to Test Superstring Theory
As the unification quest has forged ahead, physicists have found it necessary to expand superstring theory to include vibrating membranes -- called branes for short. These are not just two-dimensional surfaces, like the skin of a drum or the world of the Flatlanders. Hard as it may be to picture, there can be branes with three, four, five or more dimensions. These "surfaces" can be tiny like the strings but they can also span across light-years.by George Johnson
I know this may seem a little slow but if the cosmic string was considered in context of the Fresnel lens and I apologize for my ignorance, how would reverse imaging account for gravitational lensing?
The gravitational lensing has to reveal the warp field as such a possibility? Yet, in that distant time, such alteration of the shapes, amongst it event, would have show two points, but would also have indication that one was the reverse of the other. What signatures would we see of this?
So in keeping with the direction we were given by Lubos in his article, I a am trying to comprehend.
This page is the beginning of a demonstration of strong gravitational lensing about a pseudo-isothermal elliptical mass distribution (PID). You can look at a simple animation or read about the mathematics behind the PID lensing.
