Age of the Universe
The goal of the project is to find the age of the universe according to the theory that there were equal amounts of the two uranium isotopes U235 and U238 at the time of the Big Bang. At present, there are 137.7 U238 atoms for each atom of U235. We know that the half-life of U235 is 0.71 billion years, and the half-life of U238 is 4.51 billion years, we used this information to determine the age of the universe. We started by looking at the problem mathematically and then after figuring out the age of the universe with the above information. We proceeded to look for other sources of information about the age of the universe with supporting data. The two largest sources that were found were a Seattle University professor and a theory proposed by Edwin Hubble. Using the information above, we Y238(t) = Y238(0)ekt = No ekt Where No ekt is initial amount presumed equal
The simplest explanation for the existence of so many spiral galaxies, including our own Milky Way Galaxy, is that they and the universe are much younger than has been assumed. Such estimates typically yield ages in the range 14-18 billion years Hubble Time The inverse of the Hubble constant H has the units of time because the Hubble law is v = H d where v is the velocity of recession, H is the Hubble constant, and d is the distance. A cluster is a system of galaxies containing from a few to a few thousand-member galaxies, which are all gravitationally bound to each other. " It seems as though there is scientific data everywhere to prove and disprove any theory. If it is exactly equal to the critical amount, the expansion will slow, but will only stop after an infinite amount of time. Torsell, David L. Thus, from this equation, we have that 1/H = d/v. Thus, it is a measure of the age of the Universe. "Computer simulations of the motions of spiral galaxies show them to be highly unstable; they should completely change their shape in only a small fraction of the assumed evolutionary age of the universe. One theory that I would like to ponder is the "Big Bang"; the foundation of the "Big Bang" is that nothing imploded from nothing and the outcome was the universe. Associate Professor of Chemistry, Seattle University, 1999 George Mulfinger, Jr. It resembles believing in God, people are convinced that God is God and he came from nothing he just was and always will be.
