Thanks a lot, marcus! I knew Friedmann equation, but it DOES relate to some model. And I think when my physical skills and knowledge improve, I will try to know more about these theory and some models. And I, wondering why IT IS DIFFICULT TO FIND MANY INFO ABOUT HUBBLE PARAMETER.(even in...

If you were being in 60 hundred millions years ago, and measured the High-Z SnIa (as I mentioned above) And you would find that the H is 30 also. (For the light need 60 hundred millions years to pass to present,2007; I will also measured the H of 30 by the High-Z) NAMELY, Both our values...

I can't agree that the age is reciprocal of Hubble constant(H0). Eg. The constant of very-far(high Z) supernova Ia is about 30. And those Supernovae is represented of many "thousand millions years' present" But the reciprocal of 30 can refer the age of 320 hundred millions years old As your...

Hubble "Parameter"& acc. Universe I am a senior high student. And I am studying on SnIa. I recently read that SOME(maybe most) theory said that hubble's constant is not a CONSTANT, it's changing by time. But I wonder if there are something influent the data. (like "slection effect" .etc)...
