Universe Age and Size
.Age- Infinite
Size-300,000 Light Years -
Einstein
Einstein's theory of relativity twice that the theory of Newton was proven correct by Professor Stanley Eddington. -
Constant
Einstein added the cosmological constant to solve the problem of the debate of the universe expanding or contracting. -
Dr. Shapley
Dr. Howard Shapley used the hooker telescope to find a common center of gravity for the clusters that were orbiting. -
Solar Eclipse
-Scientists needed a total solar eclipse to detect the bending of starlight becuase they needed to see the stars near the sun. -
Period: to
Time
-
Age
-The Universe was 2 billion years old
-The size was 280 Million Light Years -
Dr. Hubble
-Hubble took photos of spiral galaxies using the 100 inch hooker telescope, he settle the debate between Curtis and Shapley. -
Three Facts
-Hubble discovered three types of galaxies, spiral, eliptical, and irregular.
-Andromeda was proven to be outside the Milky Way.
-The faster a nebula is from us the faster it is moving away. The Universe is always expanding. -
Age
-Age is 6 billion
-Size is 4-8 Billion -
Three Facts
-There are two types of supernovae, type 1 and type 2.
-The Big Bang Theory and the Steady State Theory existed in the 50's
- The difference between the two types are a difference in the elements of hydrogen. -
Baade
-Walter Baade deduced that there are two types of of cepheid stars and they have a different period-luminosity relationship. -
Age
-Age 10-15
-Size 25 Billion Years -
Three Facts
-Without Princeton University, Penzias and Wilson would not have gotten an answer.
-At least three scientists have missed cosmic backround radiation within their data.
-You can meaure the speed of stars by spliting the light into spectra, spectra contain linse that shift to the speeds of the stars. -
Penzias and Wilson
-Arno Penzias and Robert Wilson's base research led to the discovery of radiation coming from a hot, dense ball of matter and energy that existed from the beginning of the universe, -
Age
-The universe's age was 12-20 Billion
-The universe's size was 30 billion light years. -
Extra Fact
-Henrietta Leavitt's theory in 1912 was proven incorrect by the new "standard candles", scientists have discovered in 1993. -
Three Facts
-We cannot see dark matter but we do react to the gravity it gives off.
-The universe started off as a dense ball of energy, always expanding.
-As the universe cooled and expanded, it produced quarks, electrons, protons and neutrons. -
Age
-The universe's age was 13.7 billion
-The universe's size was 94 billion light years -
Three Facts
-The composition of the universe is 73 percent dark energy, 4 percent atoms and 23 percent dark matter.
-CMB=Cosmic Microwave Backround
-Cosmic Microwave backround is the remaining light from the beginning of the universe seen today. -
Mather
-John C Mather is a NASA scientist who won the Nobel Prize in Physics for discovering more information about the cosmic microwave backround.
