Any news on the heavier elements?

  1. Have they ever retried to recreate the heavier elements, such as
    element 118? I have heard no news since they retracted the statement
    that they had created element 118. I looked in the wiki for Ununoctium
    but the last thing it says is that they retracted it.

    I was wondering, is it even possible to create such a heavy element? If
    there is no news, then perhaps it is because it is impossible. Is there
    anything in quantum chromodynamics that would suggest that such a heavy
    particle could not exist? Perhaps because the moment it is created it
    decays and hadn't really formed an element except as an intermediate
    phase..

    I would seriously like some feedback on this topic.

    The "island of stability" for superheavy elements requires very large
    neutron-proton ratios. There is no apparent pair of parent nuclei
    that can be fused to get there - precursors rapidly beta-decay near
    their neutron drip lines. A sufficiently large neutron luminosity
    would, by multiple capture, give enormous neutron-proton ratios plus
    beta-decay to progressively ratchet up the atomic number of a heavy
    precursor. If you could sustain an H-bomb for a few hours instead of
    a few microseconds...
