AI Thread Summary
The discussion explores an experiment to determine if the one-way speed of light (OWLS) is the same in both directions. The initial scenario posits different speeds of light in opposite directions, leading to a discrepancy in signal timing between two observers, A and B. The results indicate that the OWLS is not the same, as shown by the differing time differences calculated from the signals sent and received. A follow-up verification with equal speeds yields consistent results, suggesting that the initial conclusion may be flawed. Ultimately, the participant acknowledges a mistake in their reasoning, indicating the complexity of the topic.

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...
 
So I know that electrons are fundamental, there's no 'material' that makes them up, it's like talking about a colour itself rather than a car or a flower. Now protons and neutrons and quarks and whatever other stuff is there fundamentally, I want someone to kind of teach me these, I have a lot of questions that books might not give the answer in the way I understand. Thanks
