Models for Compactification from Inflation?

AI Thread Summary
The discussion highlights a paper advocating for evolving extensions to inflation models, emphasizing the potential for new insights in cosmology. It references recent research on circumventing the no-go theorem for accelerating universes in M theory through a time-varying internal space, although this space is expanding rather than compactifying. Additionally, it notes a resurgence of interest in string inflation following a significant 2003 paper by Linde and Maldacena. The conversation underscores the ongoing exploration of compactification models in the context of inflationary theory. Overall, these developments suggest a dynamic landscape in theoretical physics regarding the interplay between inflation and compactification.

Here is a good paper that is quite neat makes a good case for evolving extensions to Inflation models.

This is a more recent discussion of how the no-go theorem for accelerating universes in M theory can be evaded by a time varying internal space. However, it seems that the internal space is expanding rather than compactifying.

Today at about 4:30 am I saw the conjunction of Venus and Jupiter, where they were about the width of the full moon, or one half degree apart. Did anyone else see it? Edit: The moon is 2,200 miles in diameter and at a distance of 240,000 miles. Thereby it subtends an angle in radians of 2,200/240,000=.01 (approximately). With pi radians being 180 degrees, one radian is 57.3 degrees, so that .01 radians is about .50 degrees (angle subtended by the moon). (.57 to be more exact, but with...
