I wonder what would happen if arterio venous shunt procedure is done between say a mother and child. Child has abnormal lungs that might improve overtime. Mothers arterial blood will go into child's venous blood and child's arterial blood back to mother. Of course having same blood groups.

Sorry due to language barrier may be I couldn't express what I meant. Question is unrelated to detectable or undetectable. You are absolutely correct in this regard.I wanted to say that the farthest edge what we see and think 13.7 byrs away ofcousre detetcable, but only its past, its present not...

well i think so but by undetectable i mean what we see today as the farthest universe

when we talk of big bang we say expansion faster than speed of light why can't the crunch be faster the same way and arent the black holes a pre_crunch event

i guess it has event horizon that is like an edge

tif we presume that our finite universe has a boundry. This boundry is due to the pull of gravity. Light will slow down and then come back to us. 'i may be absolutely wrong in this'. My question is that the light we see will be from the stars surface that doesn't face us and star moving away...

as all the matter came into existence at once is it possible that the farthest stars have evolved into solar systems like ours

well thanks for correcting me a good news in this article

then what is the true distance

one more thing that confuse me is that big bng happened 13.7 billion yrs ago and the farthest star is 46 billion light yrs from us it means that it traveled faster than light initially ? Can anyone explain

i would like to know the evidence that suggests a big crunch not happening soon can you elaborate that further

why the crunch will not take very long will those events be faster than light?

doesnt that mean that our knowledge is very old

the light of stars we c comes to us with delay. Depending upon the distance we observe the past of this universe. My question is what is happening in the distant stars like andromeda at present? Can we know it? Secondly a big event in our universe like big crunch might have already set in but it...

i am amazed by the possibility that if the light reflected from Earth comes back to us after traveling in space for thousands of years we will be able to see our past. And this could happen around black holes. Has anyone found an image resembling earth?
