If there was life there 50 years ago there's good chances it has survived til today. Afaik there hasn't been any change in mars that would eradicate whatever life there is. We mightve killed the single organism we found but if we found one we can find more.

FauxPseudo, in We Might Have Accidentally Killed the Only Life We Ever Found on Mars Nearly 50 Years Ago - JSTOR Daily

There are stories that I wish would go away because they are just completely unsubstantiated. This is one of them.

TWeaK,

The article offers an explanation of the Viking test results, why do you think it’s unsubstantiated?

FauxPseudo,

Because it’s without substance. I has no substant to be aited. This claim is actively harmful to science.

You didn’t answer the question.

It’s interesting how the article you linked presents the conclusion

microbial life is not ruled out by the new results; but the fact is that the original Labeled Release results make sense with the chemistry of Martian soil as it’s now understood, no microbial life needed.

Meanwhile the paper it references concludes

the chlorine component of the chlorobenzene is martian, and the carbon molecule of the chlorobenzene is consistent with a martian origin, though we cannot fully rule out instrument contamination.

Which would seem to be the same thing but with opposite probability biases. Your link is twisting its source material.

This claim is actively harmful to science.

This is hyperbole.

niktemadur, in Spanish astronomer discovers new active galaxy

I have several astronomer friends from Spain, from where I’m standing it’s one of the world’s great academic “hot spots” for good astronomy.
Not only that, but one of these friends specializes in Active Galactic Nuclei and Blazars, I even entered the article hoping it was my friend. Cue Ron Howard narration voice: “It wasn’t.”

niktemadur, in Time ran slowly in the early Universe, just as Einstein predicted - Advanced Science News

I have to wonder how this slowing down of time affected the Universe when it was still an inconceivably dense point that suddenly went into inflation mode, where and when time dilation must have been nearly as extreme as in the immediate proximity of an event horizon.

Saneless,

So did time even move at all at a single dense point?

niktemadur,

And how has any black hole in the Universe grown in mass at all in the past 13 billion years if time stops there? Any matter within the event horizon should be falling towards the singularity but frozen in time, frozen in its’ fall, never quite making it there.

How does any supernova ever even finish collapsing into a singularity?

acockworkorange,

The way I understood it way back when I was taking basic physics in college was thus (simplified): Time for the particle at relativistic speeds / gravities moves slower compared to a far away observer unbound by such influences. Like the twin siblings paradox. So a particle past the event horizon of a black hole would basically cease to experience time, but if we could see it, it would move otherworldly fast into it.

btaf45,

If time didn't "move" there would still be that single dense area (there was never a point).

No time -> no motion no movement no changes.

If time slows down but there’s no one outside to experience it, does it make a sound?

Interesting, I remember there was a CGP Grey video on this if anyone’s interested: vid.priv.au/watch?v=SumDHcnCRuU

What an incredible picture! The scope of it always boggles my mind.

I remember this movie based on the Michael Crichton book. In seriousness though I’m excited for this!

Ghyste,

The Andromeda Strain. Amazing book.

Mindblowing. I never even thought of things that way!

It makes sense, but it’s also annoying. Now instead of which planet is closest, the question should be which planets in our solar system have the closest orbital radius to ours? And then it can still be mars and venus. Thankfully in school the question was based from the sun outward. In which case the order isn’t fussed with.

This article reads like a smarmy kid who just wants to say the clichéd “acktually” with it’s technical truth.

It’s like asking “how much of the earth is water” vs “how much of the earth’s surface is covered by water”. Those are two very different answers, but if you ask people the first with no context they will answer with the answer for the second most of the time because it’s the thing we’ve heard so much from schooling days.

I love that more and more open source science projects are streamlining deployment and encouraging folks to just try it. This one has a binder link in the README (though it seems to be failing… may need some TLC). I really think this is a positive template for what academia could eventually become!

foo, in How Might Life Migrate Through the Universe?

Very. Very. Slowly.

Is any documentation available? I only found the C++ documentation, but no Python documentatikn so far. Nothing linked on PyPI either.

Select your component under ‘name’ in the chart and then you’ll get more info with a set of docs for each.
