    Thanks for your time and attention.

    We have never observed anything in the universe just popping into existence from nothing (…)

    if we did, that would be a major shift in physics. in this regards I heard of (or read of) two candidates :
    .1 if universe’s expansion continues to accelerate, (it would mean) dark energy is increassing.
    .2 an excess of hydrogen (clouds) outside of galaxies was observed that is difficult to explain with current cosmology.

    I know these are not direct observation of something popping up, …but still.

      Yeah, dark energy is an interesting theory. I certainly don’t understand enough about it to really be able to judge it, but it kind of feels like we’re following our human tendency again, to find someone/-thing to blame, without that really aiding the explanation…
