Hi
This question may have already been answered elsewhere. If so please accept my apologies in advance.
I am confused!
The textbok(s) I am reading describe a whole bunch of different causes for there being temperature fluctuations in the CBM, so I am confused about which one(s) of these effects is the mai cause.
For example, I understand the biggest apparent difference is caused by the Earth's peculiar motion relative to the coming frame of the CMB. Then looking at the graph of CMB power spectrum as a function of angular scale, am I correct in believing that the first big peaks are due to acoustic osscilations? And if so, how does the integrated Sach's-Wolf effect fit in with this? Further more I read about quantum fluctuations in the matter density distribution during inflation. Am I correct in believing that these are supposed to be responsible for the large scale structure(s) such as galaxies we find in the universe? And is there evidence of this also in the CBM.
Please excuse my ignorance and when answering try to assume with all due respect that you are talking to a very young child! I am not a young child but I do have learning difficultiesThanks
Peter
