The Hubble deep field image was constructed by collecting photons from a specific region of space over a continuous duration of time; in this case ten days. As the number of collected photons increase, higher the resolution of the image. If this duration increases, how much more resolution do...

Is there a formulation of any of the relativity theories in terms of complex analysis? As in - I imagine - every event would be a complex number in a complex field.. or something as such..

I have read that Albert Einstein was quite (pleasantly) surprised to read Schwarzschild's solution to his field equation because he did not think that any complete analytic solution existed. However, of all the possible scenarios to consider, a point mass in a spherically symmetric field (ie, a...

As long as there is no reason to think that the data might not be accurate, the age should not matter.

HI, I am looking to find a table of galaxies, their masses, types, black hole mass and dark matter content. Does anyone know if such a place exists anywhere on the internet? I'm trained in physics but is not a physicist - more a hobbyist. Any suggestion that you might have will be greatly...

Thank you. I think I misunderstood what the origin of "time dilation" is and PF has saved me yet again! I have a follow up question. Let us say that we have a galaxy at redshift z and some Hubble velocity 'v'. This galaxy is observed to have a cosmological time dilation by a factor 'B' {ie, a...

Since galaxies are moving away from us, shouldn't they be contracted in length than they would be if they were at rest (wrt us)? In other words, are we observing increasingly shrunken galaxies as we look deeper into space? When measuring supernova light curves, we do adjust for time dilation...

HI - we know that the orbit of mercury precesses (I hope I am using the right terminology here). Which basically means that the orbit seems to undergo some sort of rotation in the ecliptic plane. Does this also mean that the period of Mercury's orbit as seen from the Earth is not uniform but...

Please allow me to ask two other stupid questions, which I am sure the learned minds here will be able to clear with no difficulty. I find my mind coming to these questions by itself and then it forces me to bother all of you - I apologize on behalf of my mind. 1. Suppose there is a laser that...

Thank you for taking the time to write this description. I am very grateful for your help.

Thank you so much! I think I understand where I went wrong now.

I would say yes - but this might also be where I might have some basic misunderstanding. But I do agree that 1 microsecond in the muon clock is 10 microseconds for us and vice versa.

If I understand you correctly: Suppose in one frame of reference, and event begins at T1 and ends at T2. Interval ΔT = T2 - T1. In a moving frame, T2' = T2γ and T1' = T1γ (as T1 and T2 are simply co-ordinates of time in this frame) ΔT' = T2' - T1' = T2γ - T1γ = ΔTγ ..? But you are saying ΔT'...

I'm sorry but I don't really see how this applies to my logic - could you please tell me where I have assumed simultaneity in the argument i put forth? (thanks for the book recommendation btw. I will look into it)

γ = 1/√(1-v∧2/c∧2) in the equation that i wrote. So that T' = T/√(1-v∧2/c∧2) = Tγ... Did i go wrong somewhere?
