Document Summary
Expansion amplified quantum mechanical vacuum fluctuations. =primordial seeds of stars, galaxies and clusters today. *this theory predicts there should be roughly the same amplitude of fluctuations on all scales. The end of inflation: oll dow(cid:374) o(cid:374) o(cid:374)e side of the (cid:858)(cid:373)e(cid:454)ica(cid:374) ha(cid:454)(cid:859) Forces of nature split from each other. May be due to: random quantum mechanical fluctuations. May happen in some places earlier than others. Regio(cid:374)s of (cid:858)(cid:374)or(cid:373)al(cid:859) space-time will expand at c. Space between them is growing exponentially: inflation may never stop. Predicts fluctuations in the universe (seen in micro background) are adiobatic and gaussion observed. Many free parameters not strong prediction. Inflation should leave a very particular pattern in the polarisation of the microwave background. 10 2014: bicep2 exp claimed to detect this. Basic ides of gague fields d spontaneous sym. breaking is very well motivated in particle physics. Explains the unification of electromagnetism and the weak force.
