Putting that all together gives about two million years for the whole sky (http://www.wolframalpha.com/input/?i=(148510660)%2F(4.6)*(2+million+seconds)+in+years ) The research paper: http://hubblesite.org/pubinfo/pdf/2016/39/pdf.pdf , http://iopscience.iop.org/article/10.3847/0004-637X/830/2/83/pdf, https://arxiv.org/abs/1607.03909 (all the same paper) Other source: http://hubblesite.org/newscenter/archive/releases/2016/39/full/, http://www.darkenergysurvey.org http://www.stsci.edu/science/goods/
