#2>Even in the distant past, during the period of cosmic inflation that occurred before the Big Bang, that background radiation was present
What does "before the Big Bang" mean? Don't space and time break down at the Big Bang singularity? Didn't cosmic inflation happen 10^-36 seconds after the Big Bang?

#3The Higgs field is and was a thing, right? In that sense, the universe has never been empty, but only in the sense of the scale and diversity of matter.

Yeah, it's hard to understand what that means because the furthest point back in time that we know of could be looked at as the beginning of the big bang, even if there was a delay of some kind before the most significant expansion.

#5Anything thing that talks about "Before the Big Bang" isn't science. It may be philosophy or mathematical speculation, but it is not science.

There is as yet insufficient data for a meaningful article.

#7It's sad to see this kind of pop-sci garbage. This isn't science, it isn't even philosophy. It's pure speculation.
And hey, speculation is fine - but as soon this kind of speculation is phrased in an authoritative "this is how it is" kind of way, it becomes absolute garbage IMO.
It's even worse when it comes from an actual scientist.

Ok?
Not everything in the world has to be science. Some things are not science. It’s fine.

#9This article doesn't make any sense. Skimming over it, I don't see that it's even about "before the Big Bang," which is a nonsense phrase. Nor do I see why it's arguing the point that our universe has even been empty, because nobody has ever argued that it was.
Ah, it's talking about the future, when it might be "empty", and explaining to the reader how it won't actually be empty. That's weird.
Ah, it's now circling back to "cosmic inflation... Before the hot Big Bang occurred." What? That is one of the most wrong things I've ever heard about the early universe.
