This so called "science" is nothing but speculation. They don't know but just grandstanding for attention. More fake
news.
They're not looking for attention, they're looking for money.
One of my brothers is a PhD in Physics, and a Prof at a very large University in the east.
He told me that most of his timeis spent in and the biggest requirement of his job is, finding money.
The University takes half off the top, his Dept keeps the rest.
Not education, but grant searching.
And, since almost all the grants are from taxpayer money (Feds), that's who he needs to suck up to.
Ergo, whatever the grantor is looking to confirm is what he needs to come up with.
Think about that.
