The temperature of the fireball drives the resulting mix of particles and radiation, and we can divide the Universe evolution into four stages; heavy particle era; light particle era; a radiation era and the present day era of matter. As the Universe expands its temperature and density decline.
What is the order of the Big Bang theory?
A summary of the Big Bang events occurred in this order:
- Big Bang beginning – a bright and hot event →

- Elementary Particles – photons create particles and antiparticles →

What are the 3 types of universe?
We will first consider the three most basic types. There are basically three possible shapes to the Universe; a flat Universe (Euclidean or zero curvature), a spherical or closed Universe (positive curvature) or a hyperbolic or open Universe (negative curvature).
What are the 3 different models of the universe?
Three Models of the Universe: Flat, Open & Closed.
Who created universe?
Many religious persons, including many scientists, hold that God created the universe and the various processes driving physical and biological evolution and that these processes then resulted in the creation of galaxies, our solar system, and life on Earth.
How many dimensions are there?
The world as we know it has three dimensions of space—length, width and depth—and one dimension of time.
What does the closed universe theory say?
(in cosmology) a hypothetical expanding universe that contains sufficient matter to reverse the observed expansion through its gravitational contraction.
Who created the God?
We ask, "If all things have a creator, then who created God?" Actually, only created things have a creator, so it's improper to lump God with his creation. God has revealed himself to us in the Bible as having always existed. Atheists counter that there is no reason to assume the universe was created.
