B Challenge to humanity to see beyond and further than the CMS

  1. Mar 17, 2016 #1
    The CMS or cosmological background permates the whole universe. It's mentioned so often in study halls and on documentaries that NOTHING can peak further back into the universe evolution beyond the CMS.

    Just want to hear all of your ideas on how YOU would solve this problem if you were on this project.

    It's not a technical issue, it's a feature of the universe. Light could not penetrate the universe before the instant that the CMB.

    There are two known ways to look further back: gravitational wave astronomy, and neutrino astronomy. Both are in their infancy.

    The universe was about 300,000 years old when the CMB was produced.
    The Cosmic Neutrino Background was made when the universe was about 2 seconds old.
    Primordial gravity waves would date to about 10^-36 seconds

    No, it isn't. All that is "mentioned so often" (btw, rather than a vague statement like this, you should give specific references) is that we can't see further back than the formation of the CMBR using electromagnetic radiation. But there are other sources of data that can tell us about events further back; newjerseyrunner mentioned a couple, but there are others as well, such as the relative abundances of light elements.
