SUMMARY

The discussion centers on the phenomenon of superluminal jets emitted by certain galaxies, which appear to travel faster than the speed of light. Participants suggest starting research with the Wikipedia page on superluminal motion to understand the underlying physics and relativity theory. The assignment requires a two-page report that explains these measurements while clarifying that relativity theory remains intact despite these observations. Key concepts include the nature of jets, the speed of light, and the principles of relativity.

PREREQUISITES
  • Understanding of relativity theory
  • Familiarity with astrophysics concepts
  • Knowledge of superluminal motion
  • Basic research skills for academic writing
NEXT STEPS
  • Read the Wikipedia page on "Superluminal motion"
  • Study the principles of relativity and how they apply to astrophysical phenomena
  • Investigate specific examples of galaxies known to emit superluminal jets
  • Explore academic papers discussing measurements of superluminal jets and their implications
USEFUL FOR

Students studying astrophysics, researchers interested in cosmic phenomena, and anyone seeking to understand the implications of superluminal motion in the context of relativity theory.

I've got this assignment but have missed a few classes due to a health reasons.
To be honest I have no idea for how to approach this problem. I don't ask you guys to answer it for me but I'd like to know what I can do to approach this problem. For example, what should I read and think about in order to be able to answer this question.
I have to write a 2-page report on this question. I'd really appreciate any help.

Homework Statement



Some collections of stars called galaxies release jets of gas. Some of these jets have been measured to travel faster than the speed of light in a vacuum. Write a two page report on these measurements and explain why relativity theory is not violated.

hi appplejack! :smile:

start with http://en.wikipedia.org/wiki/Superluminal_motion" :wink:

(in case you're wondering, i got it by googling ' jet "faster than light" ')
