SUMMARY

The discussion clarifies the relativistic effects of two objects moving away from each other at significant fractions of the speed of light. Specifically, if observer A perceives objects B and C traveling at 0.9c, the separation rate observed is 1.8c. However, from the perspective of B and C, they each observe the other moving away at 0.9945c due to the principles of special relativity. This illustrates the non-intuitive nature of velocity addition in relativistic physics.

PREREQUISITES
  • Understanding of special relativity principles
  • Familiarity with relativistic velocity addition
  • Basic knowledge of the speed of light (c)
  • Concept of inertial reference frames
NEXT STEPS
  • Study the Lorentz transformation equations
  • Learn about relativistic velocity addition in detail
  • Explore the implications of time dilation and length contraction
  • Investigate real-world applications of special relativity in modern physics
USEFUL FOR

Physics students, educators, and anyone interested in understanding the principles of special relativity and its implications on the perception of speed and motion.

I'm sorry this could be obvious but i thought I'de ask

ok if 2 objects travailing at 1/2 of the speed of light are traveling away from each other would you be at the speed of light or no

Nope.
 
Well, there are two concepts here. If observer A sees B and C moving in opposite directions at .9c, then A sees their separation growing by 1.8c. On the other hand, B and C each see the other moving away at .9945 c.
