What are the stages of the Big Bang theory?
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 timeline of the Big Bang?
Big Bang Timeline
| Time | Era | Temperature |
|---|---|---|
| 100 s (a few minutes) | Nucleosynthesis era | 109 – 107 K |
| 380,000 years | Recombination (Decoupling) | 3000 K |
| 500 million yrs | Galaxy formation | 10 K |
| 14 billion years or so | Now | 3 K |
What are the three parts of the Big Bang theory?
Three main pieces of evidence for the Big Bang theory are the red-shift of light, cosmic background radiation and types of elements.
What are the five stages of the universe?
The book divides the timeline of the universe into five eras: the primordial Era, the Stelliferous Era, the Degenerate Era, the Black Hole Era and the Dark Era. In addition to explaining current cosmological theory, the authors speculate on what kinds of life might exist in future eras of the universe.
Which is the best explanation of the Big Bang theory?
The Big Bang Theory is the leading explanation about how the universe began. At its simplest, it says the universe as we know it started with a small singularity, then inflated over the next 13.8 billion years to the cosmos that we know today. Because current instruments don’t allow astronomers to peer back at the universe’s birth,
How many stages are there in the Big Bang?
What are the Stages of The Big Bang! Well, since you asked, the Big Bang has four main stages. The first actually begins before it happened! Take a look: Stage 1: Oh, you mean that tiny dot?
How old is the universe according to the Big Bang theory?
Planck’s observations, first released in 2013, mapped the background in unprecedented detail and revealed that the universe was older than previously thought: 13.82 billion years old, rather than 13.7 billion years old.
What was the period after the Big Bang called?
The period after the formation of the first atoms and before the first stars is sometimes referred to as the Dark Age. Although photons exist, the universe at this time is literally dark, with no stars having formed to give off light.
