As you put it, "light just traveling one speed no matter circumstance or direction" is a perfectly logical idea, but not enough to explain the experimental results. But it must be true to some extent, because photons red or blue shift when we move towards a source of light, and or away. Coz we're passing wave crests more or less frequently depending on our own relative motion to the light. So what you say is also true, but there must also be something else going on. As perplexing as this is, I believe there to be a reasonable answer. But what? | |

| Mar 14, 2016 at 12:43 | comment | added | Steve | Beautiful, thank you guys. Bob walks one of the 2km long interferometer legs at 2 km / hr. So it takes him one hour each way, total two hrs. Twin Bob walks the adjacent 2 km leg, however aided by an escalator at an additional 1 km / hr. Traveling at 3 km / hr it takes him 40 mins to reach the furthest point of the leg. On turning around, the escalator begins to impede his progress. Walking at 2 km / hr against a 1 km / hrs escalator, he makes headway at 1 km / hr, it takes him 2 hrs to travel the 2 km. Added together, it took him 2 hrs 40 mins in comparison to the other bobs 2 hrs. love it | |

| Mar 14, 2016 at 9:07 | comment | added | Bill Alsept | So how long would it take to walk 3 km against the escalator? | |
| Mar 14, 2016 at 7:34 | comment | added | John Rennie | In your example set the escalator speed to 2km/hr. Bob now takes an infinite time to return on the leg with the escalator because his net return speed is zero. | |
| Mar 14, 2016 at 7:24 | comment | added | CuriousOne | @BillAlsept: The velocities are in the denominator, not in the numerator. 1/3+1/1=4/3, which is not the same as 1/2+1/2=1. | |
| Mar 14, 2016 at 7:13 | comment | added | Bill Alsept | I'm curious why wouldn't the times be the same? Say the distance is 3 km one way and 3 km back again. Traveling with the escalator is 3 km/h and traveling again's the escalator is 1 Km per hour. Wouldn't that be a four hour round-trip for either paths? | |
| Mar 14, 2016 at 6:58 | comment | added | dmckee --- ex-moderator kitten | Please take what @CuriousOne says seriously and calculate the travel time of the scenarios you suggest. The two walkers don't take the same time in the course of the trip. Really. Do the math in detail. | |
| Mar 14, 2016 at 6:26 | comment | added | CuriousOne | What trouble are you having with calculating this scenario? $v=ds/dt$, from which you get $dt=ds/v$. Substitute the velocities and you can calculate the total time that your Bob would take along the arms of your interferometer. | |
| Mar 14, 2016 at 6:13 | comment | added | Steve | Thank you. For purposes of conceptualizing the Michelson Morley experiment, I dont know what contingency was made for the circumstance as posed in my question please? If lights travel was being aided then inhibited in one leg, in equal proportions. then it conceptual might arrive back at the detector at the same time as light in the leg perpendicular to it which traveled a constant speed. I'm assuming there must be a contingency made for this situation, because people are sure of their experimental conclusions. However I am not aware of the contingency please? | |
