Inflationary interactions with n_s < 1 (like the .96 we observe) should leave a flat line with a slight tilt downward. On large scales (smal l) inflation should dominate. We see this.<br /><br />On small scales baryon acoustic oscillations govern so we should see oscillations at large l. We see this too!<br /><br />Modern Cosmology is consistent!Joseph Smidthttps://www.blogger.com/profile/02583891162785742138noreply@blogger.comtag:blogger.com,1999:blog-4212234230338648875.post-1092577537264040452010-02-16T09:30:09.747-08:002010-02-16T09:30:09.747-08:00Stan,
