The DES data are the two-point correlation functions of weak gravitational lensing, galaxy clustering, and their cross-correlation. We use simulated data and blind analyses of real data to validate the robustness of our results. In many cases, constraining power is limited by the absence of nonlinear predictions that are reliable at our required precision. The models are: dark energy with a time-dependent equation of state, non-zero spatial curvature, sterile neutrinos, modifications of gravitational physics, and a binned $\sigma_8(z)$ model which serves as a probe of structure growth. For the time-varying dark energy equation of state evaluated at the pivot redshift we find $(w_p, w_a)= (-0.99^+0.28_-0.17,-0.91.2)$ at 68% confidence with $z_\rm p=0.24$ from the DES measurements alone, and $(w_p, w_a)= (-1.03^+0.04_-0.03,-0.4^+0.4_-0.3)$ with $z_p=0.21$ for the combination of all data considered. Curvature constraints of $Ømega_k=0.00090.0017$ and effective relativistic species $N_\rm eff=3.10^+0.15_-0.16$ are dominated by external data. For massive sterile neutrinos, we improve the upper bound on the mass $m_eff$ by a factor of three compared to previous analyses, giving 95% limits of $(\Delta N_\rm eff,m_eff)(0.28, 0.20\, eV)$. We also constrain changes to the lensing and Poisson equations controlled by functions $\Sigma(k,z) = \Sigma_0 Ømega_Łambda(z)/Ømega_Łambda,0$ and $\mu(k,z)=\mu_0 Ømega_Łambda(z)/Ømega_Łambda,0$ respectively to $\Sigma_0=0.6^+0.4_-0.5$ from DES alone and $(\Sigma_0,\mu_0)=(0.04\pm 0.05,0.08^+0.21_-0.19)$ for the combination of all data. Overall, we find no significant evidence for physics beyond $Łambda$CDM.
