Holes in the ground
If it turns out they're no good for habitation, we can always use them to store all of our nuclear waste.
Do you mean Morlocks?
It will create a greater number of more energetic collisions.
Re: Brit adventurer?
If he lost a load of food it seems quite reasonable he'd want to leave before he started going hungry. He wouldn't want to risk a safe departure by being too weak to climb down safely.
Re: In this case
Except that taking artifacts wasn't illegal in the 18th or 19th centuries, at least not in many countries. Now it is, and rightly so.
Re: Sunset clause
I forsee coalitions as being a way of life. Remind me, who do I vote for if I don't want this shit ?
Got to start somehwere, else it's just same-old, same-old.
Re: Can someone explain ...
I’m not saying that you are in a minority of one but you do perhaps have to respect the will of the masses.
Are the masses voting on this issue, after a healthy, well-informed public debate?
Didn't think so.

They do say they want to try to model a mouse brain in this first stage; a human brain comes later. Much later, I'd say.
Slapping and zapping? Sounds like this Sethi bloke has, um, specialist interests.

There's a telephone hotline you can call to shop the thieving so-and-sos. Go on, use it. Or go tell the bloke in the pub who told you about the fraudsters to use it. Or did you get your info from the Daily Mail? Well, I suppose the DM journalists will have called the hotline then, won't they? No?

Usually pronounced "boffeeeeeeeen" for some unfathomable reason.
An inability to communicate in standard English?
Re: Reaching out
Today's vomit-inducing neologism was the introduction of 'onboarding', used as a noun. I can just about guess what it means. I can also guess that my communications with that user will be kept to an absolute minimum.

Re: particularly clueless politicians
> 'There are some – particularly clueless politicians.' I'm not quite sure what this is supposed to mean.
a) Clueless politicians in particular
b) Politicians who are especially clueless
> But what is the alternative?
Encourage them to educate themselves a little before speaking, rather than to simply pontificate.
Part of the problem is the effect of 24-hour rolling news and social media over the last few decades, which encourages people to spout off without knowing the facts. When did you last hear a politician respond to a journalist's unexpected question with something like "I don't know. Call and ask me tomorrow, once I've had a chance to research the facts and give them due consideration."?
“want to know what it takes to work at nsa? check back each monday as we explore careers essential to protecting your nation.”
So they're happy for foreign nationals to apply? Best not let the local security service find out.
Anyway, maybe that's not the sort of protection we want from them.
In an area of mostly gas, collapse should be much smoother, and more of the original angular momentum is retained.
In an area of mostly gas, collapse would be much slower and more prone to disruption from all those planetisimals in your AUs-wide ring. Look at how Jupiter has kept the asteroid belt from forming into a planet. It would take far, far less to stop an amorphous cloud of gas from starting to spin in its own right, without something already at its centre to hold it together.
Re: Question regarding the Big Bang
A singularity is a dimensionless point of infinite density, so it's difficult to see how it could be described as an explosion. Our mathematics breaks down at that point, but then our theory of gravitation breaks down long before, when the collapsing mass reaches the quantum scale, so really we don't know (and possibly can't know).
I see no reason why the gravitational collapse of fluids and the gravitational collapse of a collection of discrete solid chunks should be treated as the same.
Can the materials in the inner and outer systems be treated as chunks in the first and only fluids in the second? We're talking about dust and ice crystals, which will behave much the same while they remain small (an approximation to a fluid) but both will then accrete to become chunks. The ice won't become gaseous again until there's enough heat for it to do so (via Kelvin-Helmholtz, perhaps).
and secondly that although largely homogenous, local non-uniformity in a gas cloud will lead to uneven gravitational forces, and regional collapse. Matter will move away from areas of lower density, and towards areas of higher density. Conservation of angular momentum will lead to rotation of this mass in the direction of rotation of the parent gas cloud.
Those areas of higher density becoming planetisimals, which then compete amongst themselves to gather more gas and ice. How likely is it that one will grow large enough to grab the majority of the gas directly (which would gain its angular momentum from a dominant direction) rather than gain mass from collision with other planetisimals (which would have a more scattered distribution of momenta, due to energy loss from breakups).
Also, bear in mind that whilst a gas cloud may start off as homogenous, once a star forms at the centre and fusion begins, the solar wind exerts a pressure which sorts the elements by mass, with heavier metallic elements ending up in the inner planets, and lighter elements ending up in the outer planets. Hence rocky planets with metallic cores followed by gas giants and icy bodies.
Thanks, I'm well aware of that, but I meant homogeneous within an orbit, where you're expecting your spinning gas cloud to form.
Give me time to finishing typing! ;-)
There's only one gas cloud and that's the planetary nebula itself. It will be spinning in the same direction as its star. Accretion of ice crystals occurs first by electrostatic attraction, and then by gravitational attraction. At that point there are millions of planetisimals in an orbit, which eventually collect into planetoids and finally a planet, sweeping its orbit clear of debris. Your hypothesis requires something to separate a cloud out of that homogenous pre-planetary mess and give it rotation, but if there isn't already a planet there to do that, how might it happen?

Re: Welcome to our country
"But anyone who thinks about it has to accept that the gov doesnt make money and doesnt create jobs."
Complete rubbish. Government can invest to create jobs. It can subsidise projects to attract further investment. It doesn't have to make money on the deal, just get enough back from the increased tax revenue over the longer term (and the consequent reduction in unemployment and related costs) to match the initial cost of investment. Breaking even and creating social benefits is a perfectly good aim.
Re: It's getting a bit like Facebook
"the problem being that anybody sensible would opt out of taxation given the opportunity."
And expect everyone else to pay for your use of roads, ambulances, etc. But what happens when everyone has opted out of taxation? Oh, yeah, a libertarian paradise. Right.
Re: It's not just the speed up.
BTW the "zero energy pathways" thing I think refers to passing between 2 orbits in this universe with zero energy expenditure
Yeah, that's what I thought. An example would be kicking a vehicle just hard enough to take it out of Earth orbit and into a solar orbit which intersects with, say, the future position of Mars. It effectively uses the Sun to fall from Earth to Mars, the trick being to arrive with just the right velocity to insert into Mars orbit.
That's the giveaway line, no American NSA insider would ever use the word "arse".
That's what they want you to think.
Some people are so utterly convinced, against all evidence, that their particular form of woo works that they will die for the cause -- or be killed by an equally-convinced "practitioner".
The worst story I heard was of an Australian woman with bowel cancer. She started off by acting on normal medical advice, but hated the surgery and chemo that she went through. That's understandable, but it caused her to abandon medicine and turn to a homeopath who swore she could be cured by "gentler, natural" means. Sadly her disease progressed and she stuck with the homeopathy even when her abdomen was visibly distended by the mass of tumours. In the final four days before she died (most probably of dehydration), her blocked bowel caused her to vomit faeces.
Of course if she had survived, the homeopath would have claimed it was due to homeopathy rather than to the earlier surgery and chemotherapy.
Surely, according to homeopathic principles, the less penicillin contaminant there is, the greater the allergic reaction?

If that was at a boarding school he'd be more likely to claim not to have had sex with a Sixth Former.
Re: Plenty of free advice sites
Well, I just glanced at the WebMD website (partnered by Boots...draw your own conclusions)
Does it offer homeopathy?
So who do you think will win in this battle of the boffins?
