A SPIDER WEB IS THE BEGINNING OF THE UNIVERSE
The information described here was gleaned from the article by Robert Roy Britt that was noted in the last post. This is a more detailed description of what was discovered from the image showing cosmic radiation emitted across the universe just after the Big Bang. This image is the first evidence ever discovered that confirms scientists’ theory that the first seconds of the existence of the universe was a time of super expansion. It also gives clues as to how exactly this expansion was able to occur.
The data was derived from observations of the cosmic microwave background. According to the article by Robert Roy Britt, the Cosmic Microwave Background was created “about 380,000 years after the Big Bang, when the universe had first expanded enough to cool and allow atoms to form. Around that time a dense and impenetrable primordial cloud cleared out. The radiation escaped in one form and, over time, its wavelengths were stretched to the microwave range by the perpetual expansion of the universe. The remnant radiation retains an imprint of the end of that era and hints about what occurred before, much like the patterns on a cloud’s exterior provide clues to its insides.” This microwave radiation has spread throughout the universe over time. Its temperature is nearly uniform across all of space, but extremely small variations in temperature reveal clues about the structure of the early universe. The temperature ranges from 2.7251 to 2.7249 degrees Kelvin. According to Britt these locations of variation were the earliest “lumps and bumps” or “seeds for galaxies and stars.”Scientists have not yet found any evidence indicative of what happened to those places of temperature variation, but they imagine that “nodes” of matter were connected with filaments of matter, like a spider web. Hydrogen, like droplets on a spider web, developed and eventually gathered at the nodes of matter. Here the matter gathered to form the first galaxies.
