The Planck Era
Fun Facts About the Planck Era?
The Planck era had no gravity or forces. The four forces gravity, electromagnetism, strong nuclear force, and weak nuclear force were combined into one super force.
Fun fact about the Grand Unification Era?
In this era, the distinction between matter and forces that carry protons has completely vanished.
What is a fun fact about this era?
During this era the universe expanded in a fraction of a second, faster then the speed of light! this was pretty phenomenal as space isn't restricted by the cosmic speed limit.
Fun facts
The universe looked like white-hot fog with a heat of about 1 billion kelvin.
The universe was so hot that light was unable to escape.
Fun facts about this era
The name "Recombination" is a misnomer as this was the first time electrons and protons had ever been bound together. During this era the universe would have looked orange.
When was this era?
The era lasted from time zero to 10-43 seconds.
What time did the Grand unification era exist?
It was from 10-43 to 10-35 seconds
When was this era?
The inflationary era was from about 10-36 to 10-32 and the electoweak era continued from 10-36 to 10-12
When was The Cooling Era?
The Cooling Era lasted from 10-12 to 3 minutes, but some sources argue it started later due to other eras before it.
When was this era?
What marked the beginning?
Nothing marks the beginning
What marked the beginning?
The beginning is marked by the separation of the first fundamental force: gravity.
What marked the beginning of this era?
The separation of the strong nuclear force
What marked the beginning of this era?
This era is marked by the separation of the final two fundamental forces: Electromagnetic and weak forces.
What marked a the beginning of this era?
This era is marked by the universe cooling to allow ionized atoms to "pair up", a process called Recombination. At this point the universe turned from opaque to transparent (atoms were scattered enough that light could pass through).
Types of matter/particles in the Planck era?
Particles like electrons, photons, and quarks did not exist.
What types of matter/particals are in the grand unification era?
In this era, it was extremely hot, so the definition of a particle breaks down at this temperature.
What matter was there in this era?
There was a bit more matter then anti-matter which led to the building blocks of the universe
What matter was there during The Cooling Era?
As temperatures decreased, density became close to that of Earth's atmosphere. This shift led to protons and neutrons coming together to form light elements such as deuterium (an isotope of hydrogen) and helium.
What types of matter were in the era?
During this era, there was hydrogen and helium, which was in a 3:1 ratio.
Other important information about the Planck era
In the planck era all understanding of time and physics breaks down.
Important information about the Grand Unification Era?
It was very hot and dense. It lasted less than a trillionth of a trillionth of a second. Additionally, this was when gravity separated from the other three forces.
Other important info
This era technically continued for 300,000 years, but contains a bunch of mini sub-eras.
