The link looks promising, thanks a bunch !

Great answer helped me formulate my real question exactly :) If i have Lat/Long info and the sat position(83) what's the formula to use to get the bearing and elevation. (I am actually making a satellite finder app for the smart phones, you could simple point your phone in the sky and it will...

So what does 83 deg means? can you elaborate a bit more or maybe point me to a web page which offers more information, i want full details and calculations, how can i find a satellite in my sky if i have the degrees (83) thanks for you time

Hi, I know what geo stationary orbit is, my question is what does it mean when they say satellite is at "83.0°E", don't you need more coordinates to find it??

According to my understanding waves are produced when something is waving... like a bunch of people *oscilating* to produce a mexican wave at the football stadium or the water waves where the water moves up and down to create a wave, in that sense what is waving when we say an electron is...

Ever since 10th grade when i got to know that electron is *also* a wave i have been wondering if electron is a wave then "whats waving?" When i asked my physics teacher this he threw me out of class (almost :) ) I understand in case of photon i guess the electromagnetic field is waving but...

Thanks a lot for clarifying but how come square root of 2 is fixed?

Hi, I have a really stupid question :smile: suppose the base and perpendicular are both length 1 (whatever units) then the hypotenuse's length comes out to be SquareRoot of 2 but square root of 2 is 1.41421356.... (not a fixed number) so that means if i physically measure the...

Is our moon slowly receding? is it getting further from us? if so why?

That was really enlightening (actually it explained a lot of things i was confused about... kind if an aahhhhaaa moment :smile:) , where can i read more on this?

Great there's a happy thought :rolleyes: Yo easy bro... didnt get that... need to think about that for a while... so we will never ever see past CMB but why won't the photons ever get past us (... thinking... when they get past us new ones will take their place..)

One more question what will happen to the CMB as time goes by, i am guessing it will get more and more red shifted and the light travel time will increase as time passes. Can you suggest some book or online material where i can read up more on this stuff? Thanks a lot for your time

:confused: Damn why didnt i think of that

Thank you for such detailed explanation, i got what you mean i plugged in z = 1090 and i got these values It is now 13.666 Gyr since the Big Bang. The age at redshift z was 0.377 Myr. The light travel time was 13.665 Gyr. The comoving radial distance, which goes into Hubble's law, is...

Great :biggrin: i understand that the source was close to us when it emitted the radiation and now its far far away but we see the CMB as coming from around 13 billion ly, what is the reason its coming from 13b?
