Yep, but this sphere must have radius up to 14Bly, to be part of BB.

  The observable universe has a diameter of about 47 billion light years! https://imagine.gsfc.nasa.gov/educators/programs/cosmictimes/educators/guide/age_size.html https://imagine.gsfc.nasa.gov/educators/programs/cosmictimes...

    Then we need to move the time of BB to 47/2 = 23.6By. Moreover, we should do that every time when we improve our telescopes.

      Correction... I meant radius of 47 billion light years. It's about 94 billion light years across!
