Foil 19 More Tests of General Relativity

From Numerical Formulation and Solution of Collision 0f two Black Holes CPSP713 Case studies in Computational Science -- Spring Semester 1996. by Geoffrey C. Fox


Observed time delay of radar signals bounced off planets or spacecraft during superior conjunction
  • so that signals are affected by close passage to sun
Observed decrease in period of binary pulsar discovered by Hulse and Taylor(1975)
  • Consistent with energy decrease due to radiation of gravitational waves predicted by general relativity
A laser monitors distance between Moon and Earth showing that they both have same acceleration due to sun with a precision of 7 parts per ten trillion(1010)
  • Tests Equivalence Principle
