While it is true that photons have no mass, it is also true that we see light bend around sources with high mass due to gravity. This is not because the mass pulls on the photons directly, but instead because the mass warps the space-time through which the photons travel.
Aisa isliye kyuki light straight path ko follow kerti hai...aur space time apas me related hain...to black hole space me ek hole create kerta hai....aur light sirf us path ko follow kerti....space agar path hi twisted hai to light bhi waisa hi vyavhar karegi
I have a doubt with the mathematical equation,i.e., E²=(mc²)² + (pc)² When v=0 , then whole (pc)² term is zero . So, we will be left with E=mc² . Now you told for photons there is no mass ,so putting m=0 , we get: E²= (pc)² E=pc . But p= mv as momentum is the product of mass and velocity. -(i) Now, replacing m=0 in equation (i), we get: p=0×v p=0 Putting this value in E=pc , we get: E=0 From this we get that photon has zero energy . Since any object cannot have zero energy, it cannot travel at a speed of light. Now again, taking the equation E=pc, we get: E= pc (For photon) E= mv × c (As p= mv) Since, v = c for photons, so we get that: E= mc× c E= mc² which is same as that of an object at rest. Please solve my doubts about this equation in the next video.
U Anand bro wait I m not saying vgyan TV told u wrong information but bro they just skeep to told u about something which is momentum I m not talking about normal momentum I mean to say about momentum of light bro which is not p=mv but it is p=gama×mass×speed of light bro I can't put sign of gama bcoz my keyboard don't have so now we r taking about momentum of light so bro here gama is=7.089 so when we solve this we will get the diff result bro

Big bang happens much later the disturbance in energy due to which a singularity born which led to big bang and creation of universe/miltiverse.so how big bang be a cause.
Don’t u think so...by breaking time barrier we can travel faster than light speed.. that is what called warp drive and that is what nasa trying to do with IXS enterprise.. i already have made video on that check it out.

Both of your questions are nice One more question from my side (may you help me with my confusion) In that train's example the boy standing outside was noticing the train(which was a single system)so for him also the photon should strike the two mirrors at the same time because ofcource the RHS mirror was moving away from that bulb but the bulb itself was moving with the train so the distance between that bulb and the two mirror must be constant from outside too...

Nope it is not about the bulb and the mirror it's about your eye and the mirror If train is moving it is in your left so your distances between your eye and right mirror is more than the left one so you will feel that distance between right mirror and bulb is more than that of left one
I am confused---- Aapne kha ki jin object ka mass nhi hota vo Light Speed pr travel krega . And uski energy hogi E= pc. Now photon ka mass nhi hota, momentum. p = mv hota h to vo bhi 0 ho jayega phir light ka momentum kse hua?
Sir , par electron Ka speed CERN ke LHC me speed of light ke 99.99 % tak kaise jata hai , Jabki koi bhi mass wale object ya particle ko speed of light se chalne ke liye infinite energy chahiye. Sir plz reply my answer.
Actually speed of light is not 3*108m/s it is 299 792 458 m / s but we do not use this value while solving questions and if u wanted to know how we calculated this value there are many videos on RUclips please watch it
Because according to the Einstein special theory of relativity speed of light is absolute in this universe irrespective of the intertial frame of reference
@@sagargyawali8506 NO..it was Newton not Einstein who said’speed of light is absolute’,but Einstein corrected this and gave that Space and time are relative.space and time cannt be seperated from each other by any means.(theory of relativity). its like a fishing net.
Extra ordinary explanation but i have one doubt if mass is 0 than than momentum is also 0 because the momentum is the product of mass and velocity if the mass is zero than pc is also 0
There's no reason for their existence that we know till date..We should combine General relativity and quantum mechanics to know it which is impossible for us by current theories
There are some possibility of the singularity. In theories time between big bang and singularity is a bounce. And..... In hindu mythology it is bhramadivas. There are possibility that every black hole in universe merge one by one and forms a singularity!!
I want to ask a question if photon is mass less means it mass =0 then how black hole gravity can absorb it bcz it does not feel any force bcz force is mg n m=0 so how light got absorbed n if it got absorbed then photon have mass so how it can travel with light speed as Einstein said a object with mass cannot travel with light speed ??????? Pls answer my question soon
Bhai sai hai question tmhara Aur photon completely massless nhi hai photon ki speed hi wo ultimate speed hai jo achieve ki ja skti hai..............n i truly believe in conversion of mass to energy(light) aur jb kisi cheez ki speed bdh kr light tk phochegi to uska pura mass energy me convert ho chuka hoga.😊 What i believe.
In my opinion, as per Hindu mythology, mind is the only means to cross the speed of light. An individual whose mind is fully under control can achieve it. Means to control mind is meditation and concentration. Einstein may be one individual to achieve it. Mythology also predicts that such experience is only individual. This experience has no( intellectual concepts of) language OR Grammar to share with others. This experience is the GOD experience which we all seek. We can all achieve this without any, quarrels OR blood bath.
@@bentennyson3255 what i have heard of big bang theory it suggests that before big bang there was an infinitly small point which had infinite mass that is what i believe is the reason for continuous expansion of universe(the infinite mass) and then that mass breaks down into energy and smaller masses(on big bang) so the total energy and mass in total is conserved . So from this point of view i believe energy and mass are related and only there conversion takes place from energy to mass and vice versa. While what we have studied when it comes to photon it can't be considered as energy directly those are considered as packets of energy. A lot of questions can be worked out from this point but i think the concept of wave particle duality can resolve those.and yes i think I'll require some more research for telling you how energy and photons are quite different
I feel this is the best video i have ever seen on RUclips. It was the most informative explanation on this topic. Great job guys. This was the first video of yours that i have seen and straight away after watching i have subscribed your channel. Great job.
becoz, according to special theory of relativity, if a object moves in higer velocity, it's mass increases from it's rest mass, so in case of photon when photon is moving through the speed of light or near spedd of light, it's relative mass increases, and in this equation the term P is the relative momentum of object , so the rest mass of photon may be 0, but it's relative mass is nit zero... that's why here m(rest mass)=0, but p(relative momentum) is not zero
@@abhishekkumar2315 bhau , pahle thik se dekho inka question, normal mass wala koi object se to koi problem nehi hai, uska to mass, momentum sab kuch hai, usse kuch problem nehi hai, sab thik hai, par inn janab ka question tha 0 mass wala object yani photon k liye...
Light speed. and even. More. Than that. Speed is. Possible. However at present we may think it as impossible. As we all know that nothing is impossible. Or any thing for which we think or imagine. Can be made possible if we achieve or find the ways & circumstances which may lead us to. Achieve it. In this case we know that our. Thoughts. are faster to travel with more speed than that of light. So if we any how succeed to supersede it. We will make it possible
Momentum of an object is equal to the mass of the object times the velocity of the object. So in case of photons, if mass is 0 for the first part of the equation then it will be 0 for the 2nd part aswell i.e (pc)2 means energy will be equal to 0
Why people take it in wrong way? It's not about the speed of light which is 3 lakh km/hr. It is about constant speed with respect to any reference (either in motion or rest). If we travel with the speed of light, we can only see the present (without any delay due to speed of light coming into your eyes). But if you travel with a speed which is constant then it is possible to travel in time. Speed of light is not important, nature of light is important due to which it's speed remains constant with respect to any reference.
Anyone give me answer Sir, you say that E=mc2 is used when things are not moving, but but in universe all things are moving respectively, then E=mc2 is possible ??????????????
But,if the observer(who is out of the bus) is watching the photons,then the speed of photons(light) will be added to the speed of the bus(for the observer) Take the speed of bus 'x'. Speed of light=300000km/sec. Then,speed of light for the observer= x+300000km/sec. You said faster than light is impossible. Explain how.

Speed of light agar koi particle haasil kar le then uska mass nhi hoga Aur phir khte ho ki agar koi particle speed of light se travel kare to uska mass bahut zyada hoga What the hell
*Aur phir khte ho ki agar koi particle speed of light se travel kare to uska mass bahut zyada hoga- Are ye assumption base pe samjhane ki kosi hai, ki agar pahali question wrong jo tumane likhi to niche wali sahi honi chachiye, joki nahi hai. that means pahali wali sahi equation hai. See one this video one more time ...might be they clear your concept. Thanks
Kehne ka matlab ye hai ki agar kisi particle ka mass nahi hoga to vo speed of light se travel kar sakta hai Agar kisi particle ka mass hoga aur phir vo speed of light se travel karega to uska mass infinity ho jayega..explained by E=MC2
Brother I am student of business studies .. All of the reason I understand why faster than light travel is impossible except last one ...by god so many equation...end of this video I have realized that I had taken good decision to take Commerce...
i will like to differ about the logic of the train and light bulb u mentioned.. In the second figure u have moved the points A and B but have not changed the position of the light?????? how can this be possible?? when a compartment is moving everything must move as an unit but u have shown the light bulb as stationary.. so your logic of hitting the mirror A first is baseless..what we can say is that mirror A will be closer to the outside observer if the train is on the right of the observer outside,hence light from mirror A will reach the observer first after defraction !!!!
You are correct.. in all videos of this channel he always does tweaks to prove his point... which is totally wrong and unethical...he should stop giving lessons if he don't have understanding himself..
My thinking is that: Past, present, future of any body does not change, but we can see only present because we do not have enough power to interact with space - time field.
bhai dekh maan le ki particle masles hey to uske liye e=PC... par P is momentum... momentum equals to mass × velocity.... then P is zero... this E= 0.....🤦♂🤦♂🤦♂🤦♂🤦♂.. bina energy woh masless particles pure brahmand me ghumta rahega on speed of light.... means usme koi energy nahi rahegi... bina energy aur bina energy ka partical kese posible hey??? yah to usme mass hoga.. yah to usme energy... dono nahi hey fir bhi uska wajood hey to mass aur energy ke alaava koi rahasyamay tisri raashi hogi 🤦♂🤦♂🤦♂🤦♂🤦♂

rest mass is zero so momentum is not zero
Bro p=E/c
Not p=mv
P=mv is wrong
Great Explanations 👍
Best utube channel... And best explainer
When we derive expression for phase velocity of wave.. Then why we write phase velocity of matter wave is greater than speed of light
Why scientist believe in point of singularity?
Can u please explain the reason of existence of singularity??
There's no reason for their existence that we know till date..We should combine General relativity and quantum mechanics to know it which is impossible for us by current theories
There are some possibility of the singularity. In theories time between big bang and singularity is a bounce. And..... In hindu mythology it is bhramadivas. There are possibility that every black hole in universe merge one by one and forms a singularity!!
I want to ask a question if photon is mass less means it mass =0 then how black hole gravity can absorb it bcz it does not feel any force bcz force is mg n m=0 so how light got absorbed n if it got absorbed then photon have mass so how it can travel with light speed as Einstein said a object with mass cannot travel with light speed ??????? Pls answer my question soon
Bhai aap gravity ko space-time ka curve samajhiye. Aur general relativity kko padhiye aapko Aapka answer mil jayega.
Photon is not massless......it is the same thing as to achieve 99.99℅ of light speed.perfectly 100℅ is not possible..
Bhai sai hai question tmhara
Aur photon completely massless nhi hai photon ki speed hi wo ultimate speed hai jo achieve ki ja skti hai..............n i truly believe in conversion of mass to energy(light) aur jb kisi cheez ki speed bdh kr light tk phochegi to uska pura mass energy me convert ho chuka hoga.😊 What i believe.
In my opinion, as per Hindu mythology, mind is the only means to cross the speed of light. An individual whose mind is fully under control can achieve it. Means to control mind is meditation and concentration.
Einstein may be one individual to achieve it.
Mythology also predicts that such experience is only individual.
This experience has no( intellectual concepts of) language OR Grammar to share with others.
This experience is the GOD experience which we all seek.
We can all achieve this without any, quarrels OR blood bath.
@@bentennyson3255 what i have heard of big bang theory it suggests that before big bang there was an infinitly small point which had infinite mass that is what i believe is the reason for continuous expansion of universe(the infinite mass) and then that mass breaks down into energy and smaller masses(on big bang) so the total energy and mass in total is conserved . So from this point of view i believe energy and mass are related and only there conversion takes place from energy to mass and vice versa. While what we have studied when it comes to photon it can't be considered as energy directly those are considered as packets of energy. A lot of questions can be worked out from this point but i think the concept of wave particle duality can resolve those.and yes i think I'll require some more research for telling you how energy and photons are quite different
Kya gajab knowledge hai aapko..... Waaa.... Maja aa gaya... Thanks bro...you have an Excellent explaining skills...
Awesome video, i just subscribed and will watch all your videos soon
The Pythagorous example was just a amazing way to understand this theory.great video
in case of mass-less particles , where is the momentum coming from?
Displacement
Bahut hard .... If particle is massless then how mumontum releation is possible
It's wave nature
Momentum coming from force results from energy p=E/C ...
Momentum does not require mass and even velocity....it only needs energy...plz check Google
Bhai shuv is trah to momentum increase hoga to speed kam ho jayegi because p=E/c h.
Why speed of light decreases in denser area like water.
Refractive Index
Too good explanation
The video not only talks of beliefs but proof it with proper analysis
Great work Sir.Thanks a lot 🙋
I feel this is the best video i have ever seen on RUclips. It was the most informative explanation on this topic. Great job guys. This was the first video of yours that i have seen and straight away after watching i have subscribed your channel. Great job.
When mass is 0 then equation is
E=Pc
Where P is momentum
And momentum= mass×velocity
But here mass is 0 so P =0
And E =0
I am confused.
Help.
Mujhe bhi same confusion hai😅😅
Same confusion bro
becoz, according to special theory of relativity, if a object moves in higer velocity, it's mass increases from it's rest mass, so in case of photon when photon is moving through the speed of light or near spedd of light, it's relative mass increases, and in this equation the term P is the relative momentum of object , so the rest mass of photon may be 0, but it's relative mass is nit zero... that's why here m(rest mass)=0, but p(relative momentum) is not zero
@@sudiproy8793 bro they doesn't talk about photons but speed of the object
@@abhishekkumar2315 bhau , pahle thik se dekho inka question, normal mass wala koi object se to koi problem nehi hai, uska to mass, momentum sab kuch hai, usse kuch problem nehi hai, sab thik hai, par inn janab ka question tha 0 mass wala object yani photon k liye...

Hi Akshat i want to know who is thisnSmeer Sir . I like very very much his videos n would like to see him once or talk to him .
Wooow.. Great video.. Applause Explanation 👌👌
Excellent boy. Appreciation from Pakistan.
Light speed. and even. More. Than that. Speed is. Possible. However at present we may think it as impossible. As we all know that nothing is impossible. Or any thing for which we think or imagine. Can be made possible if we achieve or find the ways & circumstances which may lead us to. Achieve it. In this case we know that our. Thoughts. are faster to travel with more speed than that of light. So if we any how succeed to supersede it. We will make it possible
Be
, No
Momentum of an object is equal to the mass of the object times the velocity of the object. So in case of photons, if mass is 0 for the first part of the equation then it will be 0 for the 2nd part aswell i.e (pc)2 means energy will be equal to 0
Abey yaar 12th Mai padke nahi aaye ho kya....itna nahi pta...P=h/λ....where h Is plank constant and λ is wavelength
Sir, Higgs field k saath particle km ya jaada kyu interact krte hain..jabki wo sab k sab light ki speed se travel krte hain
Aditya Saini superb question!
It might be because , different particles have different mass.
higgs field particle ko mass deta hai.... photon particle ko nhi de pata isliye koi resistance nhi hoti
Due to size of those particles which varies as per the particles
Sandeep Gorantiwar mass is given to them by higgs boson..
Why people take it in wrong way? It's not about the speed of light which is 3 lakh km/hr. It is about constant speed with respect to any reference (either in motion or rest). If we travel with the speed of light, we can only see the present (without any delay due to speed of light coming into your eyes). But if you travel with a speed which is constant then it is possible to travel in time. Speed of light is not important, nature of light is important due to which it's speed remains constant with respect to any reference.
Thank you aapka itna achchha video
Banane ke liye 😊😊😊😊😊
Sir please make video on what is outside our universe
Sir ek video magnetism pr please explain everything how magnet works and how elctro magnet work and megnatron star
Anyone give me answer
Sir, you say that E=mc2 is used when things are not moving, but but in universe all things are moving respectively, then E=mc2 is possible ??????????????
That means we should have a light plant for traveling to other planets.
Sir but singularity of black hole rotates faster than light. Then why we not break speed of light.
Bhai , yeh Maine 3 yrs pehle Minutephysics ( A RUclips channel ) me dhekha tha...
But you made me understand....Thankyou
Sir,
Please!,explain theory of relativity

If faster speed than light is not possible then how galaxies which has grand mass moving faster than light.
Buddy in the begining of the video he already clear it he will gona discus about any object is not fastrr than light and universe is not an object
He is talking about us bro...😂
Abhi toh hamne science aur astromomy study karna start hi Kiya hai
Muje lagta hai ki future me light speed par travel possible hai.
But,if the observer(who is out of the bus) is watching the photons,then the speed of photons(light) will be added to the speed of the bus(for the observer)
Take the speed of bus 'x'.
Speed of light=300000km/sec.
Then,speed of light for the observer= x+300000km/sec.
You said faster than light is impossible.
Explain how.
I subscribed you only for explaining E=mc2.
By the way thanks
Great Video 👍👍👍
Thanks Akshay
Dimagh mai phir se xhemical locha ho geya
Speed of light haasil krna ye equations seekhnay se zeyada asaan hai😅😅😅
Very nice because you are doing good work of spreading this knowledge
So well explained...Thank you everyone for the good work
Sir i am huge intrested in astronomy. Or space or other these type of materials and knowledge and i suggest ke apko astronomy se related books bhi explain krni chahiye jaise stephan Hawking ke Einstein ke or other some famous books...
Coz isse ye hoga ke usse intrested saari knowledge hme ek he channel i mean apke channel pe mil jaegi...or don't explain movies coz wo to sif dekhne me he mza ata h vese haan aap ye zarur bta diya karo ke kon se movies mast hain...
Like my fav are all superhero moVies specially jisme IRON MAN ho you know i loVe technology so and geostorm, the cloverfield paradox, the core , lucy etc and many more technological movies

Speed of light agar koi particle haasil kar le then uska mass nhi hoga
Aur phir khte ho ki agar koi particle speed of light se travel kare to uska mass bahut zyada hoga
What the hell
Haan wahi to .....I was thinking that too
*Aur phir khte ho ki agar koi particle speed of light se travel kare to uska mass bahut zyada hoga- Are ye assumption base pe samjhane ki kosi hai, ki agar pahali question wrong jo tumane likhi to niche wali sahi honi chachiye, joki nahi hai. that means pahali wali sahi equation hai.
See one this video one more time ...might be they clear your concept. Thanks
@@ArunSingh-xv4rq magar yeh sahi hai koi agar speed of light se chale to uska mass infinite ho jayega use m=m1/(1-v^2/c^2)
Where v=c
Kehne ka matlab ye hai ki agar kisi particle ka mass nahi hoga to vo speed of light se travel kar sakta hai
Agar kisi particle ka mass hoga aur phir vo speed of light se travel karega to uska mass infinity ho jayega..explained by E=MC2
Bhai love your videos!
Good to know that.
Brother I am student of business studies .. All of the reason I understand why faster than light travel is impossible except last one ...by god so many equation...end of this video I have realized that I had taken good decision to take Commerce...
Zabarjast episode tha bhai 👌👌
i will like to differ about the logic of the train and light bulb u mentioned.. In the second figure u have moved the points A and B but have not changed the position of the light?????? how can this be possible?? when a compartment is moving everything must move as an unit but u have shown the light bulb as stationary.. so your logic of hitting the mirror A first is baseless..what we can say is that mirror A will be closer to the outside observer if the train is on the right of the observer outside,hence light from mirror A will reach the observer first after defraction !!!!
You are correct.. in all videos of this channel he always does tweaks to prove his point... which is totally wrong and unethical...he should stop giving lessons if he don't have understanding himself..
vedio starts from 1 : 23
Sir ji E.M drive se ho skta h 👍light ki speed se travel karna
My thinking is that:
Past, present, future of any body does not change, but we can see only present because we do not have enough power to interact with space - time field.
One of the best videos I've watched in a while! Wah kya explanation hai.. Isse yeh bhi sabeet hota hai ke time travel bilkul bakwas hai.
According to quantum mechanic every event has possibility to occur so faster than light is possible
bro can we make a massless body ??
@@Ray-pu3ou but how
@@manashimandal7302 simple take mass and leave bones there😆😆
Switzerland nature we already did ,see the skeleton 😆🤣😆🤣😆
bhai dekh maan le ki particle masles hey to uske liye e=PC...
par P is momentum... momentum equals to mass × velocity.... then P is zero...
this E= 0.....🤦♂🤦♂🤦♂🤦♂🤦♂..
bina energy woh masless particles pure brahmand me ghumta rahega on speed of light.... means usme koi energy nahi rahegi... bina energy aur bina energy ka partical kese posible hey??? yah to usme mass hoga.. yah to usme energy... dono nahi hey fir bhi uska wajood hey to mass aur energy ke alaava koi rahasyamay tisri raashi hogi 🤦♂🤦♂🤦♂🤦♂🤦♂
Photons me energy aur momentum don't rehta hai par mass nahi hota. Energy Matlab humesha mass nahi hota.
Abe dual nature nhi padha photon jab move karta hai toh woh wave nature show karta hai particle nhi .
At 13:48 , If mass is 0 then p should also be zero which ends up that E must be = 0
Thanks sir for giving us these interesting information in easy ways and words....
