Scientists for Astronomy

Albert Einstein

• (Special) Theory of relativity 

• E=mc^2

  • The theory did not include gravity 

• Einstein took a whole decade 

• Generalized his theory to include gravity 

  • This is referred to as General Relativity 

• Einstein’s Theory of Gravitation

Friedmann

• German is the mother tongue of physics 

• Solved Einsteins equations and predicted that the universe was expanding 

Dematre

• IF the universe was expanding it means it was smaller in the past 

• The big bang theory came from a priest

Alfer and Herman

• Two students of Gamow 

• As the universe expanded energy is being converted last 

• T= 2.7 degrees 

• They created a  theory which talked about the evolution. Of the universe to the BBT 

  • Some of that energy was left over and the temp that was left over is 2.7 degrees 

• Scientists are supposed to prove it by finding the radiation

Penzias and Wilson

• Worked for the telephone company 

• Bell Labs, located in murrayville new jersey 

• They believed communication was gonna  be via satellite

Wolfgang pauli

• Apply it to white dwarf system, you can explain their existence 

• Some particles do not like eachother 

  • One of the particles is electrons 

• It creates an outward pressure that counteracts blah blah blah

Chandrasekar

• Theory of White dwarfs 

• The mass of white dwarves is < 1.4m(sun Symbol) 

• Chandrasekhar 2unit 

• White dwarf is the end point in the stellar evolution of a low mass star 

Kyper bell

• Astronomer 

  • Predicted that there were solid bodies revolving around the sun whose orbits are larger than neptunes orbit 

    • Pluto is an example of this 

Albune clark

Bc Serius is always low in the sky it can disappear behind a building

Thomas Gold

• Pulsars? 

• Thomas gold 

• Chandrasekas - Quantum mechanics ->  special relatives -> theory of white dwarfs 

Mwp < 1.4 M☉ Chandrasekar Limit
