Age and size of universe
Age infinte size 300,000 light years -
scientist
Both Newton and Einstein's theories predicted that gravity would bend starlight as it passed by the sun -
Period: to
timespan
-
Fact #1
Scientists needed a total eclipse to detect the the bending of starlight around the sun because they needed to see the stars near the sun -
Fact 2
Einstein added the cosmological constant to his equation for Relativity to keep the universe unchangeable -
Scientist
Dr. Edwin Hubble took a picture of "spiral nebula" with the hooker telescope -
1929 Age and size of universe
2 billion years old and 280 million light years -
1929 fact#2
their are three types of galaxies
Spiral
eleptical
irregular -
Fact 1
Edwin Hubble discovered that Andrmeda is 900,000 light years away -
!955 age and size of the universe
6 billion years old and 4-8 billion light years -
Scientist 1955
Walter Baade used the hooker telescope at Mount Wilson Observatory to take images of Andromeda -
Fact 1
their are two types of super- novae and they are type 1 and type 2 and the difference between them is whether or or not they have hydrogen -
Fact 2
Type 1 stars are brighter, bluer, and lie in open clusters in Andromeda's disk while Type 2 are redder, fainter and lie in globular clusters. -
Age and size of universe
10-25 billion years old and 25 billion light years -
Fact 1
Emile le Rez, Andre Dorschkevic, and Edward Ohm all missed the cosmic backround radiation -
Fact 2
Astronomers measure the stars around their center of gravity by sutudying light of nearby stars -
Scientist 1965
Arno Penzias and Robert Wilson were trying to track down unwanted microwave signals they were detecting with the 20-foot horn-antenna in holmdel,New Jersey. -
Age and size of Universe
12-20 billion years old and size 30 billion light years -
Fact 1
The Universe started as a dense ball of energy that began to expand, distributing hot radiation and space outward in all directions -
fact 2
Without the dark matter, the gas would quickly dissipate -
Fact 3
Inflation theory states that the Universe underwent a very rapid expansion in very short amount of time causing the cosmic microwave backround radiation to be uniform in all directions that we look -
Fact 1
Dark energy 73%, atoms 4%, dark matter 23% make up the universe -
Age and size of Universe
13.7 billion years and size 94 billion light years -
Scientist
Dr John C. Mather a NASA scientist won the nobel peace prize in physics for discoveries about the comisc microwave backround -
Fact 2
Cosmic Microwave Backround is the remaining light from the beginning of the universe as seen today
