The Big Bang
What is the big bang?
The birth of the universe where it started at an extremely hot and dense point
How does the life of a star work?
Is anything able to escape the pull of a black hole?
No nothing, no objects not even ligtht can escape the pull of a black hole.
What is the base of what Earth was formed by
The debris leftover from the birth of the sun
Do scientists have all the answers and facts about the big bang?
No The big bang remains a mystery although there are many theories with facts to support them
How many stages are in the full life cycle of a Star?
There are 5 stages to the full life cycle of a star
What forms a Black hole
A black hole is formed at the end of a massive star's life after it goes through a supernova explosion and collapses into a black hole.
Why was the conditions of surface of earths crust fitting for the origin of life.
The mix of gasses and water on the surface made it ideal
What are two theories for why the Big Bang occured?
Redshifts of Galaxies and Cosmic Microwave background radiation
What are the names of each phase a Star goes through in its life cycle?
1- Nebula phase
2- Main sequence
3- Red giant or supergiant
4- The death of a star
5- The aftermath
What are three interesting properties of black holes?
spaghettification
Time dilation
No Escape
What was the first type of life on earth?
simple single celled organisms
What is an explanation of redshifts of Galaxies and Cosmic Microwave Background radiation
essentially when galaxies are moving away and show the expansion of universes.
CMB radiation was a leftover echo from the universe around 380,000 years after the big bang and it provides evidence that the universe initiated in a hot , dense state
Which phase is the most important one that a star goes through
The main sequence as it is the longest as well as most stable part of a star's life
Why is nothing able to escape a Black hole?
It all comes down to the incredible strength of the gravity of a black hole where once you reach a certain point near a black hole called the event horizon no matter how fast you are ravelling you cannot escape the gravitational pull of a black hole.
How did the debris of the birth of the sun come together to form earth?
through gravity as dust and gas came together they formed protoplanets and planetesimals which, merged, collided and evolved into layers that cooled and formed the solid surface and oceans of Earth
Who are the founders of each prediction
The theory of redshifts of galaxies was founded by Edwin Hubble
The theory of CMB was predicted by George Gamow along with his colleges , Ralph Alpher and Robert Herman
Do all star's die the same way?
No depending on weather a star is low or high mass it will die differently, low mass stars do not undergo any mass explosion whereas high mass stars explode as a supernova and leave behind a neutron star or black hole
Who figured out why time dilation exists and the closer you aer to a black hole the slower time moves?
This fact was developed by Albert Einstein
Since all the facts are still a mystery what do Stanley Miller and Harold Urey believe are the appliances for the origin of life on earth?
Stanley Miller and Harold Urey believe that it is chemical reactions powered by lightning and volcanic heat that created the elements to life like for example amino acids.
