Deflection of Starlight by Newtonian Gravity - Example Calculation

Click For Summary
SUMMARY

The deflection of starlight predicted by Newtonian gravity is only half of the deflection calculated by Einstein's General Relativity. This discrepancy highlights the limitations of Newtonian physics in explaining gravitational effects on light. The discussion emphasizes the need for a thorough understanding of both Newtonian and Einsteinian frameworks to grasp the full implications of gravitational lensing. Participants are encouraged to seek out derivations and examples to deepen their comprehension of this phenomenon.

PREREQUISITES
  • Understanding of Newtonian gravity principles
  • Familiarity with Einstein's General Relativity concepts
  • Basic knowledge of gravitational lensing
  • Ability to perform mathematical derivations in physics
NEXT STEPS
  • Research the derivation of starlight deflection in Newtonian gravity
  • Study Einstein's General Relativity and its predictions on light deflection
  • Explore gravitational lensing effects in astrophysics
  • Examine the differences between Newtonian and relativistic physics
USEFUL FOR

Astrophysicists, physics students, educators, and anyone interested in the comparative analysis of Newtonian and Einsteinian gravitational theories.

So, I have heard that the deflection of starlight using Newtonian gravity is only half of the deflection predicted by Einstein. NE1 know where I can find an example of the former calculation? thanks

Mea culpa. Thanks for the gentle reprimand. In hindsight I was bring a little lazy, But not completely,
I was so surprised in reading this (in Ripples in Spacetime) that I thought others might benefit from
a discussion. I have googled a derivation but have not yet worked through it all. I am sure I will have more
questions later. H
