It’s not unlikely the universe is full of life. But there’s no reason to think humanity is going to “discover” it anytime soon, if ever. (The emotional dream of doing so is exactly that – a kind of religious faith. See the Zaitsev quote here for the “Good News”.) This “scientific” prediction, i.e. media stunt, is just the typical tabloidism of scientism PR and corporate welfare advocacy.
My prediction is that eventually they will make some kind of observation which some of them will claim is proof of extraterrestrial life. (This has been attempted before, but they couldn’t make it stick.) Other scientists, probably a minority at first, will correctly refute this hoax but be temporarily shouted down by the establishment and the mainstream media. The same kind of thing is already happening everywhere in science and scholarship, as corporate-decreed “science” has become Science As Such, while real science has abdicated for the time being. Whatever way humanity will get it back won’t be from within the establishment.
