The evidence for biosignatures on K2-18b is flimsy, at best

A much needed addendum to the previous post on this subject from 8 days ago: https://hexbear.net/post/4615155
Lol this has happened every year for as long as I can remember.
"Scientists discover a new planet/aliens"
Then, two weeks later:
"Nevermind folks, it was just a glitch/misreading"
Btw, what happened to those desiccated Mexican mummies people went nuts over last year?
Need a Angela Collier video on this until I make up my mind.
I was going to say this. It happened with biosignatures on Venus a few years ago. Phosphene gas. Life might actually be there though.
The lead scientist who made the original claim addressed these criticisms in this interview.
Very interesting, thanks!
I found a YouTube link in your comment. Here are links to the same video on alternative frontends that protect your privacy:
How much would it blow if we're the only planet with life on it in the universe and we're actively destroying it.
I mean, you can put some very reasonable, scientifically sound assumptions into the Drake Equation and it really starts to look like we might be alone. I had a professor in college that held this view.
But you can also change the variables and it looks like life is common so idk
Id believe in God, like the Christian God, before believing that. It's too unlikely. Whether or not physics works in a way where we can communicate is another, but there's no shot there isn't some form of other sentience in the universe
Maybe it's pedantic to point this out, but I seriously doubt anything humans can do would be able to wipe out all life on Earth, and I include nuclear weapons in that. Microbes can live in some crazy environments, and it only takes one surviving for life to persist and evolve into new species.
Human beings, on the other hand, and especially human civilization as we know it, well...
Is there any good studies or models showing how long shit like heavy metals and other chemicals will remain bioaccumulating in different food-chains like in lakes or coasts?
To think that will be our mark beyond the scorched steel frames and various hotspots of radiological, chemical or environmental damage.
We could probably Wandering Planet ourselves into the sun/out of the solar system. But that'd be deliberate rather than accidental, most likely.
A little too much venom in the article and way too many maybes and unsupported claims for me to take this critique seriously
I'm waiting for the results of the second look around to confirm or disprove the original claims, either they get to 5 sigmas or they don't
F in chat for alien fart gas
