Redshift and blueshift describe the change in the frequency of a light wave depending on whether an object is moving towards or away from us.
What is the Cosmological Density Parameter 惟O?It has been clear for more than a decade that the deceleration of the universe can not be determined from the magnitude-redshift relation for first-ranked elliptical galaxies, which suffer from...doi:10.1007/978-1-4612-4762-3_39Amos Yahil...
A lot of galaxies in a very small corner of the sky. Most of the color difference comes from “cosmological redshift”; the redder a galaxy is, the farther away it is. The first galaxies date to when the universe was a bit under an billion years old, with a redshift of a bit u...
Evidence for the quantization of extragalactic redshifts is reviewed, and the author proposes a cosmological uncertainty principle, which leads to a spinor eigenvalue equation for the redshift. A redshift combination rule restricts the a... WJ Cocke - 《Astrophysical Letters》 被引量: 174发表:...

What is responsible for the earth's elliptical orbit around the sun? What model of universe creation is supported by redshift? What shape is the universe? What shape is the solar system? Which of the terrestrial planets is closest to the Sun?

Although the perspective of this idea is not clear, it might be our best shot for now.什么是引力?引力虽然是我们最早就知道的, 但同时也是了解得最少的一种基本相互作用力. 对引力的认识在历史上经历了三次巨大的飞跃, 第一次飞跃是牛顿提出了万有引力定律, 第二次是爱因斯坦提出了广义相对论, 第三次...
What is an event horizon? Studying Black Holes: We know that black holes exist but due to their complexity we can only make a few conclusions about them. Scientists who study black holes admit that they break down the laws of reality, so matter and energy may not behave as they should....
