DrmDoc Posted October 1, 2016 Share Posted October 1, 2016 Here is a link to an abstract of article published by Physical Review Letters on this very subject. Apologies, I do not have a link to the full article outside of University access. According to the abstract, "Including all degrees of freedom simultaneously for the first time, anisotropic expansion of the Universe is strongly disfavored, with odds of 121 000:1 against." Enjoy!

What does this exactly mean? That our universe is finite? Link to comment Share on other sites More sharing options...
swansont Posted October 1, 2016 Share Posted October 1, 2016 What does this exactly mean? That our universe is finite? It means the universe looks the same, on some level of resolution, in all directions Link to comment Share on other sites More sharing options...
SpecialGuest Posted October 1, 2016 Share Posted October 1, 2016 It means the universe looks the same, on some level of resolution, in all directions yeah well I get that but what does it mean beside that? Could it be indication to something on larger scale, like indication of multiverse or something? Link to comment Share on other sites More sharing options...
DrmDoc Posted October 1, 2016 Author Share Posted October 1, 2016 What does this exactly mean? That our universe is finite? As Swansont has informed, isotropy refer to the uniformity of our universe in all directions--but not necessarily indicative of a finite universe.

Mordred Posted October 1, 2016 Share Posted October 1, 2016 The determinant for a bound closed universe is the curvature. Which relates to mass density vs rate of expansion/contraction. Well prior to cosmological constant which confuses the issue. Link to comment Share on other sites More sharing options...
