So is the universe flat or is it curved? I haven't had the change to read the whole paper, yet, but, from what I understand from the paper and what the lovely people at PBS explained to me is, apparently physicists at Cornell University observed a cluster galaxies under extreme gravitation forces causing gravitational lensing. Now this is nothing spectacular as far as what observation about the universe has lead us to, but, what is interesting is that when the amplitude of light passing over these distortions in gravity are examined more closely, apparently, they fall way out of line with currently, standard, models involving the geometry of the universe which uses triangulation of areas in the Microwave Background Image and Early Super Nova in the Early universe to summize that the universe is flat. This totally flies in the face of our current understanding of the universe and could have damning implications for modern Cosmology; The universe wont expand for ever? What is driving expansion then? Our models for Dark Energy break down. I am literally freaking the fuck out over this right now. HELP ME EDU!
