A Cambridge-based team claims to find molecules on an exoplanet that are only produced by life on Earth. Don't fall for the unfounded hype.

A much needed addendum to the previous post on this subject from 8 days ago: https://hexbear.net/post/4615155

    The lead scientist who made the original claim addressed these criticisms in this interview.

    How much would it blow if we’re the only planet with life on it in the universe and we’re actively destroying it.

      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…

      I mean it’s HIGHLY unlikely Milky Way alone has 100 billion+ stars in it alone and probably like 1 trillion planets

      It’s crazy just how big the universe is frightening, were just a speck of dust.

      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

    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?

      I was going to say this. It happened with biosignatures on Venus a few years ago. Phosphene gas. Life might actually be there though.

    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
