  In this paper we prove the twin prime conjecture by showing that
\begin{align} \sum \limits_{\substack{p\leq x\\p,p+2\in \mathbb{P}}}1\geq
(1+o(1))\frac{x}{2\mathcal{C}\log^2 x}\nonumber \end{align}where
$\mathcal{C}:=\mathcal{C}(2)>0$ fixed and $\mathbb{P}$ is the set of all prime
numbers. In particular it follows that \begin{align}
  \sum \limits_{p,p+2\in \mathbb{P}}1=\infty\nonumber \end{align}by taking
$x\longrightarrow \infty$ on both sides of the inequality. We start by
developing a general method for estimating correlations of the form
\begin{align} \sum \limits_{n\leq x}G(n)G(n+l)\nonumber \end{align}for a fixed
$1\leq l\leq x$ and where $G:\mathbb{N}\longrightarrow \mathbb{R}^{+}$.
