Derived from Einstein’s theory of General Relativity, the two Friedmann equations describe the life of the entire universe, from fiery Big Bang birth to chilly accelerated expansion death.
The formulas contain an odd term known as the cosmological constant (the triangle thing with no bottom), initially inserted by Einstein to counteract gravity and keep the universe eternally unchanging. When observations showed that the cosmos was actually expanding, Einstein called this insertion his biggest mistake. Recent experiments have vindicated Einstein, showing that there is a great and mysterious force known as dark energy accelerating the expansion of the universe. Its discovery was the subject of the most recent Nobel Prize in physics, though understanding how it works has thus far eluded scientists.
Dude -- Freelancers have been asking that question, unsuccessfully, since the dawning of the ages. But I'm sure that you'll be the first to breakthrough to the holders of UW's JSS secret code.
