The cosmos theory of origins of the universe

He later added a fifth elementaether, to describe the void that fills the universe above the terrestrial sphere. However, as you'll see as we move through this section, this theory is not only a product of science but also of the times in which we live.

Special creation or supernatural intervention is not subjectable to meaningful tests, which require predicting plausible results and then checking these results through observation and experimentation.

Other advocates of creation science are willing to accept that Earth, the planets, and the stars may have existed for millions of years. Called the Plasma Universe, his model starts by noting that 99 percent of the observable universe including the stars is made of plasma.

The oldest known rocks on Earth occur in northwestern Canada 3.

Dark matter makes up another 27 percent. Time, as measured in degrees of latitude, would have a beginning at the South Pole, but the South Pole is much like any other point, at least so I have been told. Why do the planets orbit the Sun? Imagine the universe as a cake full of raisins sitting in an oven. It is not defined. Some proportion of stars, including our sun, formed in the middle of a flattened spinning disk of material. On the experimental front, cosmologists expect that inflation should have produced galaxy-spanning gravitational waves in the CMB just as it produced slight temperature and density variations. Science as a methodology likes to see itself as a revealer of the true nature of the universe, as sort of a seer that can look beneath the veil of appearance. His ideas were generally rejected in favor of the geocentric theories of Aristotle and Ptolemy until they were successfully revived nearly years later by Copernicus. But how did the histories start? The answer depends on the amount of mass that the universe contains. This marked the end of the radiation-dominated era and the start of the matter-dominated era.

Inastronomers found an even more remarkable puzzle: the universe seems to be accelerating while expanding, as if being pulled by some kind of "antigravity" force. In this section, we're going to take a brief excursion through the various theories that science has put forth to explain the origin of the universe.

It also predicted that time would come to an end in black holes. In other words, in relation to the theories in cosmology, whether the universe has always existed or began with a bang, can't be separated from the influence of the zeitgeist, or spirit of the times.

Some galaxies showed just a slight redshift. No place in the universe should be unduly lumpy. Steinhardt, for instance, is working on a "big bounce" model, which pushes the starting clock back even further, to an earlier period of contraction that smoothed space-time and set the stage for an explosive expansion.
