Whether you call it a vibe shift or a paradigm shift, physicists must be ready to challenge their fundamental understanding ...

Physicists are scrambling to understand why dark energy is weakening. In a surprising twist, we must now reconsider the ...

Ripples in the fabric of space-time called gravitational waves may be the key to solving the Hubble tension — one of the biggest nagging problems in physics.

A closer look at the Lambda Cold Dark Matter model, its core components, supporting evidence, and why new observations are ...

SDSS 巡天北天区一切片的星系分布，展示出宇宙在大尺度上存在结构。观测者(z = 0) 位于切片底部. 图中每点代表一个星系的位置, 颜色代表星系颜色, 比如红色点代表偏红的星系。此图取自Michael Blanton, Sloan Digital Sky Survey (SDSS) 标准宇宙学模型 (concordance model ...

Cosmology has come a long way since Edwin Hubble determined the rate of cosmic expansion around 90 years ago. Since the 1990s, multiple independent techniques have converged on values much lower than ...

When we think of cosmology, we might think of some of its most complex scientific theories, such as inflation or the general theory of relativity. Or we might consider its astounding discoveries, such ...

Physical cosmology, as a branch of astrophysics, is the study of the large-scale structure of the universe and is concerned with fundamental questions about its formation and evolution. Cosmology ...
