- Hi friends, Gaurav here!! Do you know, no one has measured the speed of light, infact the value 3x10^8 m/s is also wrong. his is just not some random misleading fact, it has yet to be discovered. Because the speed of light we know is two-way speed of light and not one-way speed of light. Click on the video to understand why measurement of one-way measurement of lightspeed is impossible for scientists.

Its like a torch on a frog. The more you increase the torch size(radius) more shadow it unleashes across the diameter . The diameter of knowledge is always less than the circumference of darkness..the more you increase knowledge(diameter) more the darkness increases (circumference)
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.
No it will differ
Instead of showing your idead to the World,make groundbreaking discoveries yourself.

Nice
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😅
I saw this topic on the channel "VERITASIUM" it for sure is the one of the best channel of science, but you did great too! Nice work!
The more I'm watching his videos the more I am questioning about my knowledge 💀
Don't worry you r just updating your knowledge
Same here dude 😅
Although most of his videos are good . This video is complete bullshit . Speed of light is constant in all inertial frame hence , speed of light in both directions are constant . Speed of light can be changed only if medium is changed . Giving example of cars to explain average speed of light is complete bullshit .

To find Average Speed

ok
Awesome❤❤
But why is 150km/hr wrong and the other value right
@@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

V=S1+S2/t1+t2
Here even if thr speed is given you have to convert it into distance and time
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.
This does not work as I now visually thought
Very smart!!! They did some similar in Large Hydrone Collider
Very smart!!! They did some similar in Large Hydrone Collider
Problem is you would have to assume 1 second at location A is exact same as the 1 second at location B
It's just the same video as that of veritasium in which he told why one way speed of light cannot be measured and has not been measured , but I appreciate your efforts

From Maxwell's equations
c = 1/√(μ₀ε₀)= 3 lac km/s
This equation shows that the speed of light is a constant that depends on the properties of space itself, and not on the motion of the observer or the source of light.
3:52 2v1v2/v1+v2 formula can be used so the answer is 133.3km/hr

But it is interesting to see same concept in Hindi
Keep it up 💪💪 man you are a scinece,facts, politics gigachad
i also saw that vedio
sir i studied that according to Michelson Morley Experiment it was proved that speed of light is constant in all inertial frame of reference. So, the speed of light should be constant in both the direction.
But bhai Wo experiment fail ho gya tha, null result aya tha
@@sharukamboj514 brother do you mean that there is something like eather
That experiment also measured two way speed of light not the one way speed. There was a mirror. You can never measure a one way speed of light and thats a fact.
This man is a great analysist ❤
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.
But if it does then what we know upto now proves to be wrong right
Not logical because if it happens then 3G Network would become more faster than 5G Network
@@IronMan-ke5uv Exactly that doesn't make any sense
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...
@@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

I just want to see if we can ever surpasses speed of light
Total distance from earth to sun is around 15 crore km and it takes 8min and 20 seconds(500 seconds) for sunlight to reach earth's surface
So, speed = distance/time
= 150000000km/500seconds
=300000km/sec.
The reality is distance bw sun and earth is calculated by multiplying 3lakh m per second with 8 min 20 sec
I think you are also following Veritasium because a lot of your videos describe the same things he has already done. But still as you are speaking the native language, it's a lot more easier to understand you than him. Keep up the good work dear
Yupp I totally agree.. whatever he explained was a lot similar to the old Veritasium video on the same topic....but he explained it a little better🙌

Light speed is constant in vaccume ( space), it can be vary in other conditions, just like light travels straight bt bends in under water
I've known this since I heard about the experiment where they supposedly discovered the speed of light in high school. My first thought was light will move slower through space with humidity.
Ok
So if we have two perfectly synchronised watches, we can measure one way light speed.
Can we create perfectly sync watches using entanglement property of quantum particles?
using quantum entanglement as a telecommunication method, needs a loy of tech, we haven't evolved that far...

I actually have a doubt, From a small atom to the galaxy every thing is somehow related to any type of circular shape, for example:- the nucleus of an atom is spheroid its electrons are spheroid and also their orbit around nucleus, the base of a mountain although not circle but its round(curved) - same with the trunk of a tree, the earth is spheroid the planets the sun even the galaxy is circular, even we humans for that matter - our head is round our bones are like rods but still curved... why is this??

Thank you.
Electrons are spheroid...? Huh?¿
@@Ashutosh0_0 Electrons are not actually objects. They are just cathode waves.
@@Leomessi18222 and why are you telling me this?
PS: I guess my actual reply might've been confusing, so I'm rephrasing it.
If an object covers s distance from point a to b with the velocity of 3lakh km/s and returns with the same velocity then total distance covered =2s and time1 = s/3lakh time2 =s/3lakh then total time taken = 2s/3lakh. The avg velocity will be 2s/2s/3lakh. Upon solve this equation, the avg velocity will be 3lakh km/s. So why shall we consider 2 different velocities(4lakh km/s and 2.4lakh km/s) 🤔🤔🤔🤔🤔
Nice brother. thanks for great information 🙏
T1 aur T2 ko equate kaise kar sakte hai?kyuki distance constant hai but speed varying hai toh relation satisfy karne ke liya tume ko bhi vary karna padega aur varied quantities cannot be equated
What about Maxwell's equations which calculates the velocity of electromagnetic radiations..

Can you comment on Vedic philosophy of measurement of light speed which very closely matches with modern value.
Studing for IIT ez 133km /h
Note avg velocity is not same as instantaneous velocity, the speed of light we calculate is avg , avg is defined for large distance which is not actual speed .
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
You told us that light was traveling with two different speeds so it will take different time than how could you say that t1 = t2 (x/V1 = x/v2).

But Guarav Sir what if the speed of light from A to B be 3× 10^ 5 km/ s and same from B to A then the average speed of light will be same
Ayo who knows but the thumbnail was hallarious asf 😂
according to newtons third law of motion , every action has an equal and opposite reaction . so if the light travels from point A to B with speed C , then its speed will be C to be reflected from point B to A .
Gaurav's mistake at 8:56 he says light's speed 3 lakh km/hr that is wrong but dont't mind vdo is useful😂👍😎
Gaurav bhai kya challenge hai!! Gazab 😮✌🏻
If you know the exact two way speed of light than can’t you just divide it by 2 or by that method you used in this video for calculating the speed of car and get one way speed of light?
133.33 Km/hr according to the eq. Avg speed = 2V¹V²/V¹+V²
Prove -
Avg speed = Total distance travelled / Total time taken
If the distance is d
And it covers two distances then it's 2d
Total time taken of object 1 is d/V¹ and d/V² for the other one according to s=d/t and on equating this we come to the conclusion of eq. 2V¹V²/V¹+V²

What do you mean by average speed? Light never changes it's speed, Albert Einstein bark this statement in his whole life..
mistake 8:58 he meant to say 3 lac km/sec but he said 3 lac km/h
How can u say the speed of light is different if it is not changing its medium and source from which it has been emitted...? Basically how the speed of light changed in air what is the thing that affected the speed of light??
Doraemon explaining😅 Nobita listening
And how would you say that the light is changing its speed for different distance.
How would you just assume the speed of light of 4lach and 2 lach per sec for different distance
150Km/hr. According to me 😅 now let me check whether i am correct or not.
Please don't spread rumors According to Albert Einstein's theory of special relativity, the speed of light in a vacuum is the maximum possible speed in the universe. It is independent of the motion of the source of light or the observer measuring it. This means that regardless of how fast an observer is moving relative to a light source, they will always measure the speed of light as being approximately 299,792,458 meters per second.
The constancy of the speed of light in a vacuum is a fundamental principle that has been experimentally verified numerous times and forms the basis of our understanding of the behavior of light and the fabric of spacetime.
But why you think that light speed is different in different direction
