The theory you are referring to is the Big Bang theory. It posits that the universe originated from an extremely hot and dense state, which then expanded rapidly, leading to the formation of all matter and energy we observe today. This expansion continues, and the theory is supported by evidence such as the cosmic microwave background radiation and the redshift of distant galaxies.
The Big Bang is the theory that was developed to describe the origins 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 describes the universe's origin as a singularity approximately 13.8 billion years ago, where all matter and energy were concentrated in an infinitely dense point. This singularity underwent rapid expansion, leading to the formation of space, time, and the universe as we know it. As the universe expanded, it cooled, allowing particles to form and eventually coalesce into atoms, stars, and galaxies. The theory is supported by evidence such as cosmic microwave background radiation and the observed redshift of distant galaxies.
The Big Bang Theory suggests that the universe began approximately 13.8 billion years ago from an extremely hot, dense state known as a singularity. This singularity then rapidly expanded, leading to the formation of space, time, and all matter and energy in the universe. As the universe cooled, it allowed for the formation of subatomic particles, atoms, and eventually stars and galaxies. This model explains the observable expansion of the universe and the cosmic microwave background radiation.
The Big Bang theory is currently the most widely accepted explanation for the formation and expansion of the universe. It proposes that the universe began as a singularity and has been expanding ever since, with galaxies moving away from each other. This theory is supported by observational evidence, such as the cosmic microwave background radiation and the redshift of distant galaxies.

All modern models based on science that are worth their salt would be. The only major theory I know about the origin of the universe is the Big Bang Theory, which is supported by Red Shift observations. Galaxies we can observe are all moving away (we know this due to Red Shift) from a central point, believed to be the epicenter of the Big Bang.
the big bang theory
Relativity theory establishes a speed limit for objects travelling through space - but the expansion of the universe is the expansion of space. There is no speed limit for that expansion.
