![]() ![]() Without the constant in the picture, on the other hand, Einstein’s general theory of relativity suggested that the gravitational pull of masses contained in the universe would pull all the matter together, keeping the universe dynamic. ![]() ![]() The constant had a value such that, when used in his newly created equations describing the behaviour of the gravitational force, a non-changing universe was spit out – agreeing with knowledge at the time, as well as his belief, that the universe was static. ![]() In it, he described a number called the cosmological constant. On February 8, 1917, Einstein published a paper titled ‘ Kosmologische Betrachtungen zur allgemeinen Relativitätstheorie‘ (‘Cosmological Considerations in the General Theory of Relativity’). According to his field equations, a static universe was impossible because the gravitational forces would pull all the matter together.” – Walter Isaacson, Einstein: His Life and Universe, 2007, p. His theory indicated that the universe would have to be either expanding or contracting, not staying static. But there seemed to be one hitch, a flaw that needed to be fixed or fudged. “ concept of the cosmos that Einstein derived form this general theory of relativity was elegant and magical. ![]()
