The Beginning
The earliest period in history is called
What is Planck Epoch?
Cosmic microwave background radiation (radiation from the early universe) and the redshift of galaxies (we see that distant galaxies are moving away) tells us that
What is Big Bang is correct?
When a molecular cloud collapse under its own gravity.
What is the formation of a star?
This was a hot and hostile place. There was intense volcanic activity, frequent meteorite bombardments, and there was no oxygen.
What is early Earth?
A soup of organic molecules in earth’s early oceans then energy from lighting, UV radiation, or hydrothermal vents started the formation of life.
What is Primordial Soup Theory
This was infinitely small, one dimensional, infinitely hot and dense. The size of this was planck length which is 10^-35 meters. This was Planck temp which is 10^32 degrees celsius.
What is Singularity?
This is made when the universe expands and cools. It has a 50/50 chance.
What is Matter?
When a star expands into a red giant and its core becomes a white dwarf, supernova, or collapses into a black hole.
What is the death of a star?
Thick and toxic; it mainly had carbon dioxide, nitrogen, water vapor, and methane.
What is the atmospheric composition of early Earth?
Life stared around hydrothermal vents on the bottom of the ocean
What is Deep-Sea Vent theory
Atoms were allowed to form after the universe
What is cooled?
This is made when the universe expands and cools. It has a 50/50 chance. It also eliminates matter.
What is antimatter?
When a star runs out of hydrogen it goes to the helium that was made.
What is creation of elements up to iron?
CHNOPS which are carbon, hydrogen, nitrogen, oxygen, phosphorus, and sulfur.
What is the origin for the ingredients of life?
A comet or meteor that had life on it hit the earth and seeded it
What is Panspermia
When the singularity started to expand into itself
What is Inflationary Epoch?
Albert Einstein discovered this equation . It appears three times. During singularity, fusion of a star, and matter and antimatter interactions.
What is E=MC2?
When a giant star explodes.
What is creation of elements past iron?
Must be made of cells, metabolism (obtain energy from food), homeostasis (maintain internal environment), growth, reproduction (reproduce offspring), response to stimuli (respond to light temperature, chemicals, and touch), and adaptation (adapt to their environment).
What is characteristics of life?
Combined water, methane, ammonia, and hydrogen in a closed system then subjected them with electrical sparks to mimic lighting, produced amino acids
Miller-Urey Experiment
As the universe expand what were formed
What is quarks, leptons, and hadrons?
The 3 original elements
What is hydrogen, helium, and lithium?
When gravity collapses a solar nebula making it spin faster, flatting it into a disk shape with the sun in the middle. In the disk small clumps of material are colliding, merging, and forming plants, moons, asteroids, and comets.
What is the formation of our solar system?
How was life started
What is no one knows?
Researchers investigated the chemical reactions that could lead to organic molecules under prebiotic conditions, they found that wide range of organic compounds can be synthesized under such conditions
What is Prebiotic Chemistry Experiments?
