SUMMARY

This discussion explores an experiment designed to determine if the one-way speed of light (OWLS) is the same in both directions. The experiment involved two observers, A and B, with differing speeds of light (c=10 and c=5) and resulted in a discrepancy of 30 seconds in one direction and 60 seconds in the other, concluding that OWLS is not the same. A follow-up verification with equal speeds (c=10) yielded equal results, reinforcing the initial findings. The conversation highlights the complexities and nuances of measuring light speed and the implications for physics.

PREREQUISITES
  • Understanding of the theory of relativity
  • Familiarity with the concept of one-way speed of light (OWLS)
  • Basic knowledge of time dilation and signal transmission
  • Experience with experimental physics methodologies
NEXT STEPS
  • Research the implications of one-way speed of light on relativity theory
  • Study experimental setups for measuring light speed
  • Explore the concept of time dilation in different inertial frames
  • Investigate historical experiments related to the speed of light, such as the Michelson-Morley experiment
USEFUL FOR

Physicists, students of physics, and anyone interested in the foundational principles of light speed and relativity will benefit from this discussion.

suppose speed of light varies in two directions
->c=10
<-c=5

distance=100, A and B stationary wrt each other
A...d=100...B

A resets clock and sends signal to B
A=0...B=?

10 seconds pass, B receives signal and resets clock, B sends signal to A
A=10...B=0

20 seconds pass, A receives signal from B
A=30...B=20

Now A sends signal to B, B reflects the signal, then A reflects the signal, B gets the signal. 40 seconds pass
A=70...B=60
(A sent signal when A=30, B received when B=60, difference = 30)

Now B sends signal to A, A reflects the signal, then B reflects the signal, A gets the signal. 50 seconds pass
A=120...B=110
(B sent signal when B=60, a got the signal at A=120, difference = 60)

result: 30<>60.
With this experiment, we were able to determine if OWLS was not same in both directions.

Go collect your nobel prize, I don't care.

P.S. verification: same experiment if OWLS is same in both directions
->c=10
<-c=10

A resets clock and sends signal to B
A=0...B=?

10 seconds pass, B receives signal and resets clock, B sends signal to A
A=10...B=0

10 seconds pass, A receives signal from B
A=20...B=10

Now A sends signal to B, B reflects the signal, then A reflects the signal, B gets the signal. 30 seconds pass
A=50...B=40
(B sent signal when B=10, A got the signal when A=50, difference = 40)


Now B sends signal to A, A reflects the signal, then B reflects the signal, A gets the signal. 30 seconds pass
A=80...B=70
(B sent signal when B=40, A got the signal at A=80, difference = 40)

result:40=40

Just something I noticed at first glance... From second example:
10 seconds pass, A receives signal from B
A=20...B=10

Now A sends signal to B, B reflects the signal, then A reflects the signal, B gets the signal. 30 seconds pass
A=50...B=40
(B sent signal when B=10, A got the signal when A=50, difference = 40)
B didn't send the signal, A did. So this last line should be
(A sent signal when A=20, B got the signal when B=40, difference = 20)

therefore..
result: 40<>20

Or Am I mistakin' ?

ouch...
yes you are correct...
I was so sure I found a way.. by bouncing light 3 times...
sorry...
never mind...
