What are the basic observations about the universe that any theory of cosmology must explain? Cosmology deals with the organization and evolution of the universe. A cosmology theory must explain the expansion of the universe and the Cosmic Microwave Background Radiation(CMBR).

What are the basics of cosmology?
Cosmology is a branch of astronomy that involves the origin and evolution of the universe, from the Big Bang to today and on into the future. According to NASA, the definition of cosmology is "the scientific study of the large scale properties of the universe as a whole."
What is the main theory of the universe?
Scientists think the universe began with a bang. A big bang. The Big Bang theory (no, not the TV show) is the most widely accepted theory for how the universe started.
What are the characteristics of cosmology?
the branch of philosophy dealing with the origin and general structure of the universe, with its parts, elements, and laws, and especially with such of its characteristics as space, time, causality, and freedom. the branch of astronomy that deals with the general structure and evolution of the universe.
What does the term Hubble time mean in cosmology and what is the current best calculation for the Hubble time?
What does the term Hubble time mean in cosmology, and what is the current best calculation for the Hubble time? 13.8 billion years old, hubble assumes that universe is expanding at a constant rate.
Why is cosmology important?
Introduction. Modern scientific cosmology is valuable in itself for what it reveals about the nature of the cosmos we inhabit [1]. It is a demonstration of the power of modern science to transform our understanding of who we are and where we came from.
What did the COBE observations tell cosmologists about the early universe?
What did the COBE observations tell cosmologists about the early universe? Recent observations indicate that the universe is expanding faster today than it was a few billion years ago (that, in other words, the expansion of the universe is accelerating).
What are the 5 theories of the origin of the universe?
The flat Earth, the geocentric model, heliocentricity, galacticocentricity, the Big Bang, the Inflationary Big Bang… Each model explains what was known at the time and what the measurements could confirm. We cannot say that these theories were wrong; perhaps it would be truer to say they were incomplete.
What is the theory of how the universe began?
The Big Bang was the moment 13.8 billion years ago when the universe began as a tiny, dense, fireball that exploded. Most astronomers use the Big Bang theory to explain how the universe began. But what caused this explosion in the first place is still a mystery.
What is the importance of cosmology?
Introduction. Modern scientific cosmology is valuable in itself for what it reveals about the nature of the cosmos we inhabit [1]. It is a demonstration of the power of modern science to transform our understanding of who we are and where we came from.
