I Big Bang

  1. Aug 13, 2017 #1
    I'm assuming for some time after the Big Bang we may have been close enough to another universe to observe it. Would all signature of such observation be lost due to the heat in the early universe or the length of time past? Could anything observed be a remnant of this?

    Hi ErikC, welcome to PF!

    If you mean being in contact with another patch of the universe that is currently unobservable, then that was never the case. The particle horizon soon after big bang was smaller than it is today.

    This looks like personal speculation, which is off limits for discussion at PF. If you can find a mainstream reference (textbook or peer-reviewed paper) that describes a hypothesis like this, then we would have some basis for discussion.
