Cosmological Perturbation Theory So far we have treated the universe as perfectly homogeneous: Transcript
To understand the formation and evolution of largescale structures we have to introduce inhomogeneities As long as these perturbations remain relatively small we can treat them in perturbation theory In particular we can expand the Einstein equation.

It enables us to make progress when a physical system is too complicated to be analyzed exactly. The essential idea is to solve the behavior in steps. First we approximate the system by some simple Hamiltonian whose Schrödinger equation we know how to solve. Then we add the bit missed out, and use perturbation theory to calculate how our previous results (energy . Hayato. . Motohashi. & . Teruaki. . Suyama. . (.

By the end of Chapter 2 we had made it to 1840 with the discovery of stellar parallax and correspondingly ridiculously large distances to the stars.. At this point, it is useful to introduce a device, similar to the Evil Genius device of Descartes, known as the Random Alien Test (or RAT). Under the RAT device, an alien spontaneously appears and asks random planetary inhabitants basic knowledge questions about the Universe that any "intelligent civilization" would know. So, in 1840 the RAT question would be:. The universe is the sum of all energy, matter, space and time..
