What is th? big bang th?ory? W?ll, it’s mor? than half a th?ory built to giv? ath?ists som?thing to b?li?v?, so why think th?n? W? b?li?v? in it b?caus? th? syst?m of sci?ntific ?ducation th?n chang?s than ?v?r r?ally should not b? taught in schools, but sci?ntists mak? th? curriculum of th? sci?ntific class. Nothing strong about it r?ally. But, this is off track. L?t’s talk about th? Big Bang!Th?r?for?, astronom?rs b?li?v? that th? univ?rs? was cr?at?d about 13 billion y?ars ago. During that tim?, th? ?ntir? univ?rs? insid? th? bubbl? was small?r th?n th? small?st thing you could think of, and was incr?dibly hot and d?ns?. From anywh?r?, this bubbl? thing b?gan to ?xpand. This ?xpansion cr?at?d what w? know of th? univ?rs?. In such a small tim? th? univ?rs? w?nt from th? atom of our homog?n?ous galaxi?s that ar? constantly incr?asing.According to th? th?ory of th? Gr?at Bang, th? univ?rs? app?ar?d as an individual. Th? f?atur?s ar? b?li?v?d to b? locat?d in th? h?art of th? black hol?s. Th?s? ar?as ar? call?d a d?ns? ar?a of ??infinit? “vocabulary”. Th? univ?rs? is b?li?v?d to hav? start?d v?ry small, h?avily h?at?d, and infinit?ly d?ns?. With tim? how much mor? cont?nt w? hav? with it.Th? obs?rvation shows that ?ach galaxy took th? sam? tim? to mov? from th? starting position to its curr?nt position. This obs?rvation is call?d th? Hubbl? Act, nam?d aft?r ?dwin Hubbl?, who discov?r?d this in 1929. ?dwin Hubbl?’s guid? supports th? rapid ?xpansion of our world, and indicat?s that th? univ?rs? was onc? compr?ss?d. Thirdly, if th? univ?rs? is madly hot as th? Big Bang sugg?sts, sci?ntists should b? abl? to find som? of this l?ft h?at. In 1965, sci?ntists us?d cosmic microwav? background radiation that implant?d th? obs?rv?d univ?rs?. Finally, th? discov?ry of larg? amounts of h?lium and hydrog?n l?ads to th? support of th? Big Bang Th?ory.So far w? hav? th? basics of big bang th?ory, what happ?n?d aft?r th? initial ?xpansion? In th? fractions of th? first s?cond aft?r th? initial cr?ation of what was onc? a vacuum b?gan to ?xpand into th? univ?rs?. Imm?diat?ly aft?r th? Big Bang, th? univ?rs? was ?xtr?m?ly hot, b?caus? this was th? r?sult of both matt?r and moving mat?rial moving away in all dir?ctions. As it b?gan to cool th?r? was about an ?qual abundanc? of mat?rials and antimatt?r. How?v?r, th? antimatt?r disapp?ar?d and rar?ly found at th? mom?nt l?aving only a cas? to fill it.
