what does science say about the origins of the world? Flashcards
what is a scientific belief about the origins of the world?
the big bang theory
what evidence backs up the big bang theory?
observations that can and have been tested
eg.scientific discoveries led to the suggestion that the world was expanding which led to the suggestion that the world became from a singularity
who developed the big bang theory?
Stephen Hawking
how was the world created(with the big bang theory)?[15]
1.hot dense point (singularity)that expanded
2.as it expanded it also cooled which caused matter to appear which led to clouds of hydrogen
3.the clouds are pulled together by gravity
4.pressure and temperature increases which led to a fusion reaction which created a star
5.as the the energy of the stars nuclear reaction pushes outwards,gravity pulls inwards
6.these forces are balanced until the hydrogen fuel that keeps the process going is used up
7.When the fuel begins to run out,the reaction begins to die but the gravity continues to pull inwards
8.the star is squeezed which causes helium atoms to appear
9.in a bigger star ,heavier elements are formed until iron is produced
10.once the fuel is used up in small stars,they fade away but in larger stars,a massive explosion pushes the stars matter outward in a supernova
11.the elements and star matter hurtles into space
12.shrapnel from the explosion and gases between stars mix to form new stars and planets
13.planets are formed from dust and gas particles that form clumps
14.the clumps clump together
15.it took billions of years for planets to be created created
what happens when the expansion of the universe stops?
the universe will collapse in on itself to be a singularity again
do scientists believe the world was created on purpose or accident?
accidental,it was chance that the conditions were right in order for the expansion from the point of singularity to begin
what would christians believe about the big bang theory?
literalist christians believe the big bang theory contradicts the bible whereas liberal christians believe that the big bang theory was designed by God and that it was his way of creating the universe.
