big bang theory
The steady-state theory is obsolete - it is now known that the Universe does change over time (the Steady-State Theory states that it doesn't). According to the Steady-State Theory, the Universe has no beginning and no end.
The Greeks created the theory of which they thought the earth was the center if our solar system ( a.k.a, the geocentric model)
The steady-state universe theory
Current theory is the Big Bang
Claudius Ptolemy and Nicolaus Copernicus both described the universe. Ptolemy, a Greek astronomer, wrote a book that combined all knowledge of astronomy that he could find. He expanded ancient theories with careful mathematical calculations in what was called the Ptolemaic Theory. Ptolemy thought the Earth was the center of the Universe and that the sun and other planets revolved around Earth. Although this theory was incorrect as we now know, it predicted motions of the planets better than any other theory at the time did. Copernicus, a Polish astronomer, published a new theory that would eventually revolutionize astronomy. Copernicus thought the Sun was the center of the universe, and all the planets (including Earth) orbit the sun. Although Copernicus correctly thought that the planets orbit the sun, his theory did not replace Ptolemaic theory immediately. When Copernicus's theory was accepted, major changes in science and society called the Copernican revolution took place.
The big bang theory explain the creation of everything. It gives the explanation of beginning of our universe and it's evolution
Because it is one of many theories that have attempted to explain the formation and existence of the universe; no-one can truly know how the universe reached its current state.
An accelerating universe is a theory which describes and seeks to explain the increasing rate of the expansion of the universe.
An accelerating universe is a theory which describes and seeks to explain the increasing rate of the expansion of the universe.
The Big Bang theory is the current scientific theory used to explain the origin of the universe.
An unexplainable natural thought.
The big bang theory which is a theory of cosmology holding that the expansion of the universe began with a gigantic explosion between 12 and 20 billion years ago
It doesn't really explain it as describe it. Think of the universe as sort of the smoke and debris that resulted from a massive explosion.
The steady-state theory is obsolete - it is now known that the Universe does change over time (the Steady-State Theory states that it doesn't). According to the Steady-State Theory, the Universe has no beginning and no end.
Scientists believe the "first event" in the Universe was the Big Bang. The Big Bang Theory attempts to explain how the universe was originally created.
Cosmology is defined as the science of the origin and development of the universe. an account or theory of the origin of the universe.
