Millimeter Anisotropy E Xperiment IMaging Array - Results

Results

Compared to MAXIMA's competitor the BOOMERanG experiment, MAXIMA's data covers a smaller part of the sky but with much more detail. By the end of the year 2000 the experiment provided the most accurate measurements of the cosmic background radiation (CMB) fluctuations on small angular scales. With this data it is possible to calculate the first three acoustic peaks from the CMB power spectrum. These greatly confirm the standard cosmological model by measuring a baryon density of about 4%, which agrees with the density calculated from Big Bang nucleosynthesis. The measurement of the flatness of the Universe also confirms a major prediction of inflationary cosmology, although BOOMERang was the first to discover this.

Famous quotes containing the word results:

    A distinction of property results from that very protection which a free Government gives to unequal faculties of acquiring it.
    James Madison (1751–1836)

    “The ideal reasoner,” he remarked, “would, when he had once been shown a single fact in all its bearings, deduce from it not only all the chain of events which led up to it but also all the results which would follow from it.”
    Sir Arthur Conan Doyle (1859–1930)

    The chief benefit, which results from philosophy, arises in an indirect manner, and proceeds more from its secret, insensible influence, than from its immediate application.
    David Hume (1711–1776)
