does the CMB/background radiation have irregularities/creases in it?

Question

plz show where you got your info

Answer 1

the cmb has small differences in temperature.

Answer 2

Yes it has what are usually called "ripples". They are really really tiny and it has been very hard to measure them, but we have done so, although not perfectly.

The reason we looked for the tiny ripples is that someone pointed out the big bang had to have been a little lumpy, or stars and galaxies would not have formed. That lumpiness would translate into ripples in the CMB.

So a theory guy calculated how the ripples had to look so the stars and galaxies we see today would have been formed. He said they'd be really really tiny and have a certain shape.

So we spent millions of dollars and years on building a satellite (COBE) to look for the tiny ripples. It found them, just as predicted.

That actually was the last nail in the coffin of the steady state universe. A few steady state believers had invented a variety of explanations for the CMB. They haven't been able to come up with any good theory about why there are ripples.

I know this because I've read many things about cosmology.

Much better info about this is in this book:

Answer 3

The cosmic microwave background is isotropic to roughly one part in 100,000: the root mean square variations are only 18 µK.

Answer 4

Hi. Check out "Wrinkles in Time".

Answer 5

yes
read "big bang" by simon singh. This is a great book.
