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The steady-state theory is obsolete - it is now known that the Universe does change over time (the Steady-State Theory states that it doesn't).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 event that marks the beginning of the universe is the Big Bang. This was a cosmic event that occurred about 13.8 billion years ago, creating the universe as we know it today. The Big Bang theory is widely accepted by scientists as the most plausible explanation for the origin of the universe.
The steady state theory of the universe, which proposed that the universe has always existed in a constant state without any beginning or end, has been discarded in favor of the Big Bang theory, which suggests that the universe began from a singular event and has been expanding ever since.
The theory that the Earth was the center of the universe was popularized by Claudius Ptolemy, a Greek astronomer, in the 2nd century AD. This geocentric model of the universe was widely accepted in Western societies until the heliocentric model proposed by Nicolaus Copernicus in the 16th century.
Pulsating Theory According to this theory, the universe is supposed to be expanding and contracting alternately i.e. pulsating. At present, the universe is expanding. According to pulsating theory, it is possible that at a certain time, the expansion of the universe may be stopped by the gravitational pull and the may contract again. After it has been contracted to a certain size, explosion again occurs and the universe will start expanding. The alternate expansion and contraction of the universe give rise to pulsating universe.
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 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.
There are various concepts and theories about the universe, including the Big Bang theory, multiverse theory, inflation theory, and the cosmic microwave background radiation. These concepts seek to explain the origins, expansion, and composition of the universe.
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.
A "no boundary" universe is a universe where the change in energy is positive or negative everywhere in the universe. Such a universe theory calls for everywhere expansion or everywhere contraction. The current central dogma in Astronomy is for such an expanding universe. The corrected Law of Gravity indicates that the universe is bounded and not expanding.
