    Given LQC would a massive black hole undergo inflation?

    I just read the thread on inflation is very unlikely. Then I read the paper by Abhay Ashtekar, David Sloan Loop quantum cosmology and slow roll inflation Although, I did not comprehend all of the implications what seemed to be implied was Given enough mass at some critical density...

    If the universe is expanding more rapidly now

    Thanks Chalnoth. I am still not comfortable with the explanation but you have given me a direction to go gather additional knowledge. If it would not be too much trouble could you explain how negative pressure occurs?

    If the universe is expanding more rapidly now

    OK this is where I become totally baffled by the explanations. I accept that the cosmological constant does fit the observations. What disturbs me about this explanation is that we are implying an infinite expansion in the amount of energy in the universe. The universe grows larger and more...

    Was Gravity turned off during inflation?

    Thanks. This helps my understanding of why the early universe was not a black hole.

    Was Gravity turned off during inflation?

    Do the current models of inflation contain an implicit understanding that gravity is some how turned off during the inflationary expansion? Does the scientific community believe that gravity is a temperature dependent phenomina?

    Do black holes truly never reveal their secrets?

    I think a really interesting question would be if you were entering a space time curvature would the rest of the universe appear to be increasingly accelerating away from you? I am not saying that this is what we are currently measuring beause I would expect some anamoly in the CMB that we...

    Do black holes truly never reveal their secrets?

    I think this! I think it is a logical conclusion that the book would indeed be further away from us in a curved space time then it's projection into a flat space time would have indicated. I am not sure of my conceptual pictures that I use to make sense of complex mathmatical systems and I...

    Do black holes truly never reveal their secrets?

    How would you measure the size as distant observer. Since photons traveling out of the well spread since the lip has a greater circumference than the interior where the book is the book will appear smaller to the distant observer. So not only would its red shift indicate that it was...

    Do black holes truly never reveal their secrets?

    It appears to me as if the explanation is wrong. If fewer photons are emitted and they are increasingly red shifted to the distant observer it would appear as if the book was accelerating rapidly. So wouldn't the distant observers point of view be that the object accelerated to the speed of...

    Curvature of space and dark matter

    I graduated more decades ago than I like to admit but I got curious and after some research I am blocked by these questions. It seems like the whole evidence for our universe expansion accelerating is that photons which travel a very long space time path arrive with less energy than expected...
