This principle applies only to the large-scale properties of the universe, but it does imply that the universe has no edge, so that the big-bang origin occurred not at a particular point in space but rather throughout space at the same time.

These two assumptions make it possible to calculate the history of the cosmos after a certain epoch called the Planck time. Scientists have yet to determine what prevailed before Planck time.

History of the big-bang model. Soon afterward, the dominance of matter over antimatter as observed today may have been established by processes that also predict proton decay. During this stage many types of elementary particles may have been present.

After a few seconds, the universe cooled enough to allow the formation of certain nuclei. The theory predicts that definite amounts of hydrogenheliumand lithium were produced.

Their abundances agree with what is observed today. About one million years later the universe was sufficiently cool for atoms to form.


The radiation that also filled the universe was then free to travel through space. Penzias and Robert W. Created and produced by QA International. The possibility exists that other relics from the early universe may eventually be discovered.

Where was the big bang? Learn how the centre of the universe changes with different perspectives.Physical cosmology is the study of the largest-scale structures and dynamics of the Universe and is concerned with fundamental questions about its origin, structure, evolution, and ultimate fate.

Cosmology as a science originated with the Copernican principle, which implies that celestial bodies obey identical physical laws to those on Earth, and Newtonian mechanics, which first allowed us to. The branch of learning that deals with phenomena at the scale of many millions of light-years is called cosmology—a term derived from combining two that billion years ago all of the matter in the universe was closely packed together in an incredibly dense state and that The currently accepted cosmological model is the big bang.

This is an artist's concept of the metric expansion of space, where space (including hypothetical non-observable portions of the universe) is represented at each time by the circular sections. Steady-state theory, denying any beginning or end to time, was in some minds loosely associated with atheism.

Gamow even suggested steady-state theory was attached to the Communist Party line, although in fact Soviet astronomers rejected both steady-state and big-bang cosmologies as "idealistic" and unsound.

William Lane Craig is a prolific Christian philosopher, apologist, author, and public debater. He is the best debater – on any topic – that I’ve ever heard.

As far as I can tell, he has won nearly all his debates with debating him, atheists have consistently failed to put forward solid arguments, and consistently failed to point out the flaws in Craig’s arguments.

Cosmological Theories Through History "Cosmos" is just another word for universe, and "cosmology" is the study of the origin, evolution and fate of the of the best minds in history - both philosophers and scientists - have applied themselves to an understanding of just what the universe is and where it came from, suggesting in the process a bewildering variety of theories and.
