Where Did the Big Bang Occur? | Space Questions - The Nine Planets
网页2023年8月22日 — Key to the idea of the Big Bang is an understanding that the universe is gradually expanding. In 1912 observations by Vesto M. Slipher indicated redshifting of the light from remote galaxies. This led to the theory that the galaxies may be receding from the earth or basically moving further away. A decade later using Einstein’s field ...

What is Cosmic Microwave Background Radiation (CMBR)?
网页2019年11月5日 — We can detect radiation from the young Universe. In 1989 NASA sent up the Cosmic Background Explorer satellite to measure this radiation accurately in all directions. One of the things it produced was the image above which shows a slight variation in the level of the CMBR. This tells us that at 300,000 years old the Universe was not …

How Big is the Universe? | Size, Why So Big, Infinite & Facts
网页2020年9月29日 — The Universe is so big because it is constantly expanding, and it does so at a speed that even exceeds the speed of light. Space itself is actually growing, and this is going on for around 14 billion years or so. In this amount of time, with speed greater than the speed of light, the Universe gradually grew, and it still expands even to this day.
