I remember that first report that life had been detected on Mars, followed by caution that the test was not conclusive. I wondered at the time how the test could possibly be wrong. It won’t surprise me at all if life is discovered on Mars.
Interesting. I had always heard that the Viking test was inconclusive, and... not really anything else. I didn't know there were many tests done. I didn't know anything about the nature of the tests. At least, I don't recall hearing any of this before.
I think it would make for a good documentary film.
I'm not sure what goes on with Mars but we could be hiding a lot of information. When you follow everything reported about it there seems to also be a lot of things made up.
Anybody can write anything they want, some rag will pay for it. This is a blog site, not actually "Scientific American", the well-respected journal.
Inspect the standing of your sources in the scentific community, beware of stuff "faith-based" colleges support, for just one example!
@AnneWimsey It's under the auspices of Scientific American, essentially from the editors.
@bingst repeat a BLOG where anybody can write anything.....
