"At some point, the gluons will no longer be able to hold the quarks together, and the hadrons will decay. Which will mean the end of matter in this universe." - Albert Einstein  1 As it seems, in our universe, nothing is made to last. Eventually, everything gets old and dies or changes or decays into something else and I am not refereeing to the life forms only but all matter in the cosmos. For all we know this might not be true within our own macro world alone but also deep below the same goes for particles in the quantum realm as well. The fact is that everything in the universe have a tendency to achieve the lowest energy state and to finally rest within a stable system even if that means going through various changes or decays. In the quantum world, this could be true for the Higgs field as well. According to Hawking, if it becomes meta-stable, the vacuum decay bubble will emerge and consume everything in order to eventually reach the lowest energy state possible. For

Not so long ago I mentioned great city of Alexandria in post Constantine & Naissus when I described the horrible misfortune and death of Hypatia, one of the greatest philosopher and astronomer of 4th century AD, who lived at the very end of classical Greek era of prosperity. Within the same city walls, couple of centuries before, one of the equally greatest and famous scientists of all times, Claudius Ptolemy was living, exploring, teaching and dedicating his life in various disciplines including astronomy and, of course, unavoidable astrology which was considered to be "connected science" for centuries, especially in the old ages. Rachel Weisz as Hypatia of Alexandria in Agora (2009) Among other things, Ptolemy will be remembered as the one of first scholars who described and identified 48 constellations of clear and unpolluted nightly skies above Alexandria so many centuries ago. One of the biggest constellations in his list was the great constellation of Gem
