Probably the greatest barrier to the acceptance of the binary star theory is that no one has yet observed a binary system with the exact orbits and stellar mass ratios that are being suggested by astronomers searching for Nemesis. Critics point out that it would be a more credible theory if we could point to a similar system in the night sky. Mike Brown, who discovered Sedna and Eris, thinks that most binary star systems go through this kind of orbital pattern at some time in their evolution. He concludes that the reason we have not yet found an example of this is because of the difficulty of detecting brown dwarfs so close to another star.

The belief that we are already in the ascending Dwapara Yuga gives a very different outlook than many of the theories that suggest 2012 is the focal point of a major shift. The Yukteswar view would suggest we should be able to expect steady progress toward a more enlightened society that will be provided by advances in technology. Other researchers, including Jenkins, feel that the coming galactic alignment marks the ending or midpoint of the Kali Yuga, as the alignment of the winter solstice sun with the galaxy marks galactic midnight. This viewpoint would suggest that we could expect something quite different and perhaps significantly more dramatic.
