Flashcards in origin of the universe Deck (25):
1

big bagn

one act of creation 13.82 thousand million years ago
a pure point of energy that transformed energy itno matter

particles were produce in a minute amount of time; and helth together by glue of gravity and other electromagnetic forces

2

what were the first fundamental particles

electrons and quarks; make up everything visible

3

what is gravity

no proper explanation exists for the origions;
but its a force that breaks hydrogen and leium into littl peices and makes clouds infold and collapse

4

what are atoms made up of

protons neutrons and electrons

5

quark assemblage process

quarks assembled into threes and were glue d together by electognetic forces which resulte din the creation of protons electrons and neutrons

happened in 1 billiongth of a second

6

nuclear fission process

universed exapanded as more energy entered it

at high temperatures the univrese cooled down to expand

in 10-15 minutes, protons and neutrons joined together in a process of nuclear fission at 15 million degrees; resulsted in positive electrical charge slammed into neutrals at high temperatures and speeds

7

primieval chemistry

property atoms started forming with different protons electrons and neutrons such as hydrogen

8

primordial atoms

the universe keeps expanding and cooling down into the darkness

75% hydrogen
25% helium
and traces of litium make up the primordial elements known as the 'big bang elements'

9

spectrographs

allow for us to measure th enumber of atoms in th eunivrese

10

first stars

gases compressed to form the first stars and clouds of that gas

11

proccesses in stars

atoms and matter formed energy

protons and neutrons provided light; mass is slightly less together than when seperated

when mass is lost energy is resulted (hence an equillibrium exists between matter and energy)

600 million tons of protons turns into 596 million tons of helium and energy every second; results in production of other elements such as beryllium

eventually gas will run out of fuel, gravity will compress, temperatures will rise and energy dispereses

12

death of a star

supernovas; star collapses and explodes and dies

temperature foes form hundres to thousands

results in the formation of black holes and the death of a solar systme

13

heavy element production

due to death of stars and unstable conditions;

higher elments are produced such as:
1. silicon during death
2. radioactive elements (polonium) form and decay
3. iron after death as the assembly of nuclei result in iron
4. cobalt

14

regeneration of stars

after star death matieral from supernova falls into center of clodus and spins in collapse of old star

left over temperature and matieral (hydrogen, helium and mineral rocks)

failed stars become planets

15

planet formation

death of starts produce solid surfaces

water, formaldehyde is formed in interstellar space

planet surface contains many chemical reactions


dark clous of soot and dust and sad are in contnious cycles of formign stars and planets

gas planets vs geological planets

16

our solar system (when)

formed 4560 million years ago
third generation of a cycle of star deaths and regeneariton

formation of moleculse like carbon in gas clouds

17

why is carbon important

a versatile atom that cna produce many molecules and is fundamental for organic chem

18

our solar system( what and how)

water, co, co2, nh3, ch4= fluid gas forms

collisiosn and merging leads to formation of the earth

19

collision into earth

during formation; lead to excess derbis forming the moon

it also decided the spin of the earths axis and change dht einternal structure of earth: (hot, pressured center, molten and electrical middle, crust)
- double core of hot earth
-magnetic field of earth
-tectonic plates and volcanic eruptions

20

atoms into molecule

molecules grow to form coasts and oceans on earth

6 molecules join to form dna; which is the fundament of life as it can replicate, contains the genetic code and determiens protein membranes


results in formation of prokaryotes, ohotosynthesis, paradise adn eukaryotic evolution

21

start of life

most life began microscopie as bacteria and archae

cyanobacteria did photosynthesis by liberating oxygen into envrionment

22

great oxygenation event

by cyanobacteria; resulted in eukaryotes (internal membranes and nucleus0

23

rotiffers

have cilia, suck food into vaccum

24

excintinos

1. life extinct several times
2. first extinction resulted in 90% of life dying by volcano or meteorite
3. second extinction was extinctino of dinosaurs where 70% of animals died due to meteroites and ice age

finalyl mammals evolved
