The standard model of particle physics (SM) and general relativity (GR) are arguably the best tested and most successful scientific theories in history. They provide a coherent description of known physics observed on Earth, in the solar system, and in the stars. Together, they account in exquisite detail for the pattern of light elements forged in the early Universe during big bang nucleosynthesis and provide a solid framework to consider cosmological questions. Yet, precisely because we understand them so well, we are now certain that the SM and GR provide an incomplete description of our Universe. From cosmology, we now have strong evidence: (i) that the abundance of dark matter is roughly six times larger than the abundance of ordinary atoms; (ii) that an epoch like inflation occurred in the early Universe to seed the ripples that grew to form the structures in the Universe we observe today; (iii) that the Universe today is dominated by dark energy which is causing its expansion rate to increase rather than decrease.

粒子物理学（SM）和一般相对论（GR）的标准模型可以说是历史上最佳测试和最成功的科学理论。 它们提供了在地球，太阳系和恒星中观察到的已知物理学的连贯描述。 他们共同详细说明了大爆炸核合成期间早期宇宙中伪造的光元素的模式，并提供了一个可靠的框架来考虑宇宙学问题。 然而，正是因为我们非常了解它们，我们现在确定SM和GR提供了对我们宇宙的不完整描述。 从宇宙学中，我们现在有强有力的证据：（i）深色物质大约是丰富的普通原子的六倍； （ii）在早期宇宙中发生了一个类似的通货膨胀，以播种呈现出我们今天观察到的宇宙结构的涟漪； （iii）当今的宇宙是由黑暗能源主导的，这导致其膨胀率增加而不是减少。
