isnt there a best questioner category? i mastered it probably, making others really sick with my questions. but y was mr swanshot's name not included?

ooops. it's point. sorry, dont ban me please.

how do we know the math & models are correct then?

ok. what if we dont allow them to interfere instead let them fall on two different points so that we may observe the pts. now how can the same light make two things visible at different places at the same time? does it mean if light diverges from a pt all photons it carried do travel simultaneously in all beams? what's wrong in supposing half of the photons in one beam & the other half in other beam? after all the intensity does reduce the same way. it wasnt clear sir. please explain & send me the links, name of books what i should study regarding this.

thanks. i get it. we probably cant imagine it geometrically.

pls dont mind but if we really cant visualize something how can we explain? how do we know?

if universe was a pt at the time of bigbang what was outside that pt? what was before that time?

we can see only three mutually perpendicular st line in space at a pt. if time was another dimension either we have to imagine it only or we must shrink the angles. but what is the reason of shrinking the angle? infact what is the significance of another dimension? pls explain.

actually wen i first entered the forum i saw a name appear lepton now its quark? well i think its got 2 do soth with atomic physics. can somebody tell me what those are?

both in reality as well as wht we are meant here?

what is hoghmann transfer orbit? can anybody give me the deduction for minimum energy? or tell me where to find it pls. i am a 1st yr stdnt of physics only.

black one of course if there is light around otherwise same.

how can u say light has quantized energy?

what is localized light? i think it never stops.

Merged post follows:

even if light is quantised being a wave how can a photon interfere with itself? if it has to do so it must be present in both the beams simultaneously. bt how can 1 thing be at 2 different palces at the same time?

how can u observe time without light? light signals from a pt where an event occurs reaches u & u can start measuring time. otherwise how do u understand the interval? i think light's velocity is more fundamental.

no problem. we can still try to know what light would itself observe.

a light particle/ soth moving in speed of light must be at rest wrt itself. nothing can say that its really moving. i just wanted to understand its observation.

is there any problem in assuming that mass is infinite for the frame of reference regarding my question?

Merged post follows:

if we can really measure the relative velocity of 2 photons approaching each other whats the problem in supposing that light itself is the observer?

i didnt understand. pls explain. i am a 1st yr student in physics.

if relative speed of light is constant for all reference frames-

suppose there are two light sources one moving with a speed of light itself. now light emitted from them fall on a shooter simultaneously & gets reflected to a stationary observer now since the velocity of light was c wrt the person moving with the speed of light it must be 2c wrt the stationary 1. if not the stationary observer can calculate the vel of light as 0 for the source moves with velocity c itself.

again if the vel is 2c for him he can observe the same event the shooter firing twice. for one of the lights travel faster. i cant understand. can light really be emitted then? if not what's stopping it? pls explain.

we suppose some events are occuring outside a reference frame which is moving with speed of light.

what will the person inside the frame observe?

everything occuring simultaneously or nothing occuring? both cases relate to 0 time interval.

pls reply.

let us suppose there are two particles travelling with speed of light toward each other. now one cant see the other till they collide. say there is a mirror behind the 1st 1 at a distance d from the pt of their meeting in a stationary reference frame. can the 1st 1 see the 2nd reflecting back to it & then measure the relative vel?

bt that cant also be possible for in the reference frame of the 1st d=0 & time taken by the 2nd particle to move the distance 2d is also 0.

how do we know the relative speed?

can u suggest me the expression of singularity? isnt it where some of derivatives dont exist? pls explain.

why all books call photon a particle if its a wave?

photons r actually passing through the slits, doesnt deflect. so y those r obstacles. pls explain.

what if we have a continuous source of light? how do we know which light signal to observe. 2 signals may start at different times to reach us. pls explain.

well then please explain how is actually length measured?

suppose 2 people have 2 rods of same length when they were at rest. when one starts moving the other sees the length of the rod different. y?

i didnt understand. how can the photon interfere with itself? half a photon i didnt say what i meant was half the no of photons are in one beam the other half in the other beam.

suppose u have water in a large pipe & want to distribute it in two equal pipes. half the no of molecules go in one pipe other half to the other. y this isnt true regarding photon particles???

pls explain.
