1^st^ law of thermodynamics :
There is something that will always be the same.
2^nd^ law of thermodynamics :
Everything else always changes and never will be what it was before.

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...
