Off topic: - Is the big bang theory the scientific consensus on the origin and evolution of the universe ? - What are the alternatives ?

Big bang theory really a term describing the moment the universe started and not the evolution and how things evolved with time which have more questions than answer. The standard model of cosmology is the most accepted theory about universe. But you can't have knowledge about anything before the singularity. Actually we don't even know for sure what happens in the seconds after that because we need a much more power…

Yeah - people forget that the true advantage science has over other methodologies is that it accepts that what is believed today could be proved wrong tomorrow by new data. There are no absolutes, we're just formulating theories to best fit what data we have now, and, if new conflicting data (or even existing data that was misunderstood/misread/misclassified as being irrelevant) disproves our theory we formulate a ne…

Someone I know put this well: "science is just as gullible at following the latest trends. The difference is it corrects itself, where trends never do."

I like that - and it's true, eventually science will correct itself, even in the face of ridicule from its own stalwarts (eg. the way that Robert Atkins was treated by the scientific community, right up until his theory [which was recycled] was proved with empirical data)

I'm always fascinated by the posters here who insist on second-guessing the writers and the scientists who spend their whole lives studying a topic like this. No one needs to read your post fessing up to your profound ignorance and the fact that you didn't really read the link.

Given how simple Water is and how readily available it's components are, it's inevitable there are many planets with vast oceans.

At least 30% of the bodies in _our_ solar system have vast oceans. You are right, it's inevitable.

Water oceans? It’s far far from 30% isn’t it? Is there an image of a single water ocean not on Earth?

I second this, and it tends to be a sitewide issue. HN has really changed over the past 5+ years: went from healthy or interesting skepticism to reddit-style snarkiness and shitposting.

From the guidelines [1]:

> Please don't post comments saying that HN is turning into Reddit. It's a semi-noob illusion, as old as the hills.

(With that last sentence linking to 9 examples in [1].)

You don't think it's changed? You've been here about as long as we have. At some point you can't rely on it being a noob illusion if a place actually does change. The guideline is not a magic incantation that prevents it from never becoming false. Snarky replies used to be routinely downvoted swiftly, now they are not.

I’m not arguing either side. Just saying that the meta discussion is a discussion that the guidelines try to discourage.

IOW, it’s not really relevant to the article, so it’s not promoting curious, interesting discussion.

So both this discussion as well as the snarky comments you’re arguing against are both not following the guidelines of trying to keep discussion curious and interesting.

There is an ocean somewhere near Jupyter or Saturn.

Due to some counterintuitive geothermal reasons, it's likely that three of the four Galilean moons (of Jupiter) as well as Titan (Saturn's largest moon) all sport significant underground oceans of liquid water.

For example, despite being much smaller than the Earth, Ganymede is projected to harbor more liquid water than all of Earth's oceans combined.

(Whether this adds up to 30% depends heavily on what you start counting as a "body")
