Why SPEED OF LIGHT May Actually Be WRONG | Nobody Has Actually Measured Light Speed

[@dipeshotwani5824]

Interesting perspective Gaurav! If we understand movement of light from point A to B vs B to A, probably it's difficult to hypothesize why the speed of light would be different in these cases given that it's travelling thr same medium and the same distance. So speed of light being different in opposite directions would still be an unproven assumption at best and difficult to disprove the entire experiment based on this assumption. However, one perspective that could truly pressure test this is the frame of reference. When the speed if light is measured on earth, the average speed is taken assuming that the light is travelling the same distance back and forth based on observer from earth. Now even the earth isn't static and completes 1 rotation in 24 hours. For an observer from outside earth, the point A has itself moved a bit to A' by the time light reaches from its source. And even when the light returns to point B, it has moved to B' for the observer in space. So effectively for that observer, the speed of light would be different than 3 Lac km/s. Biggest challenge is that it's impossible to define an absolute stationary object. This will always be relative.

your answer is hidden in this video already. just watch it again and again until you got your answer😅

[@Hydroverse]

I believe I have a solution for the problem. You don't actually use a clock, but light itself. The key is interferometry. Instead of your normal double-slit experiment in which the laser beam enters through both slits simultaneously, you instead shine the beam parallel to the plane of the slits. This way one wave enters through one slit before the other, and you should be able to make predictions about the interference pattern that is made if light travels at a constant rate. This is using light to tell us if it is moving faster in one direction over the other by interfering with itself with a modification to the classic interferometer that treats light waves like water waves in which the two waves that exit from each slit will modify the interference pattern made depending on the one-way speed of said waves. I've tried this myself, and I don't see any difference between shining my laser parallel to the plane of the slits when doing in both directions. Should I be correct, then all it means is that the simplest convention is true, which is that light does travel the same in both directions.

[@suhankumarchoudhury9958]

But why is 150km/hr wrong and the other value right

[@abhishekraj1186]

​@@suhankumarchoudhury9958 it's because average speed is calculated by total distance divided by total time taken and if u take distance from A to B as 200 km then total distance would be 400km as the car has to return too from B to A but total time would be 3 hours as due to the difference in speed that's why average speed would be 400/3 that's 133.33km/hr

[@RohanDreamerz]

This is a very interesting concept and I remember watching the video about this exact topic by Veritasium.

[@monireol]

I have an Idea if this works ? Step 1: You throw the first light photon from location A to B and start a countdown timer in location A. Let's assume the clocks in locations A and B are not synchronized. Step 2: After exactly 1 second of the first photon being thrown, you throw the second photon from location A. It's important to have precise timing to ensure a 1-second gap between the photon throws. Step 3: The first photon reaches location B, and you start a countdown timer in location B to measure the time between the arrival of the photons. Step 4: The second photon reaches location B, and you stop the countdown timer in location B. Step 5: Now, you calculate the time difference between the first and second captured photons using the countdown timers. Here's the analysis of the results based on the assumptions: - The countdown timer in location A would show 1 second when the second photon is thrown, as you started it exactly 1 second after the first photon was thrown. - The countdown timer in location B would show the time it took for the first and second photons to reach location B. If the time difference between the arrival of the first and second photons in location B is indeed 1.5 seconds, the countdown timer in location B would display that value. By calculating the time difference between the first and second captured photons using the countdown timers, you would find that it is 1.5 seconds (the value shown on the countdown timer in location B). Now, if we subtract the known time gap of 1 second (the time between the photon throws in location A) from the time difference of 1.5 seconds, we get 0.5 seconds. Therefore, based on these assumptions, you can conclude that light takes approximately 0.5 seconds to travel from location A to location B in this specific setup.

[@bhuwanbist2748]

It's completely weird though..say light is travelling from A to B in 10 seconds and back to A from B in 2 seconds in vacuum. So light may not have same speed as of A to B and B to A as we notice there is difference of time taken to travel same distance. So what causes the speed of light to change..they are in same medium, travelling between two fixed points. Light can't just change it's velocity itself right! That would go against the laws of physics.

[@_gamer_8073]

@@IronMan-ke5uv Exactly that doesn't make any sense

[@thatonerobloxian9440]

I am also thinking about this that how the speed of light can change. We all know that it is constant or if it is not constant then many calculations and assumptions based on speed of light are wrong. For eg- E=MC^2. In this C is the speed of light which is not constant in all the directions then Energy evolved will ultimately change in every direction and this is not possible...

[@IronMan-ke5uv]

@@thatonerobloxian9440 All of you my point of saying is not constant factor of speed of light. But the point is that if light speed was not constant then 3G network would become faster than 5G network. So this raises a question that Light speed is constant. Moreover The point of view for seeing is that 3*10^8 m/s could also be not the right value. Radio waves of networks can be speeder than our thought also. Like 5*10^n m/s etc. Actually correct speed of light is division of distance between source and end point and integration of time with extent from 0 to max second. I know it's little bit confusing but the resultant is the actual speed of light

Eg , you are traveling 10 km by bike and you took 1 hour to travel so your avg speed is 10 km/h. But it is impossible to travel in constant speed of 10 km/h due to traffic 🚦 so you might have travel with 20 or you have stopped near signal which implies your actual speed was not 10, Similarly speed of light is not completely accurate
