Just because you act like a fucking piece of shit on slashdot doesn't mean you are one. But we may as well treat you as you yourself act, so there's little practical difference. PC is a term that refers to computers which run Microsoft operating systems on x86-compatible architectures. That some few people use the term differently does not change reality. Idiot.

Also, there's no longer any such thing as "running natively" - today's x86 actually takes every instruction and translates it into microcode - in other words, the cpu is really just an x86 emulator.

For the purposes of discussing computing hardware -- if the CPU executes the instruction, it is native. It doesn't matter how the CPU goes about the business. Idiot.

Most of the stuff you highlight can be handled by a feature phone, though, except reading books. I use my 6-year-old Android, doesn't seem to crash or need to reboot unless the battery is on empty (and shocking the battery still works pretty well after 6 years - will go 12+ hours between charges). You don't need anything fancy - what you want is something stable.

I'm really struggling with what to get next - the screen on my phone has been cracked for a couple of years now, so I should probably replace it one of these days. But now it's all these damn giant phones that don't fit in my pockets, don't have replaceable batteries - what ever happened to cell phones getting smaller?

When someone sends me a text or an email, there's no "he said - she said" disputes over what was said. Try doing that with your home phone.

If you have that problem often enough to care, you need better friends, not a better phone!

Inflation was cooked up to explain most of that after the fact, though, so it's unsurprising that it does. The fundamental problem with inflation is that too much is tunable. Penrose's cyclic cosmology explains all the same stuff, and at least has the decency to make some bizarre (and very likely false) predictions outside of the early universe.

Theories of the very early universe that require new fields that there's a way to detect today are interesting. Certainly there are ideas to explain dark energy as an extension of inflation that fit that bill. But theories that propose a bunch of cool new physics that all conveniently vanished early on are a bit sketchy, at least until we can somehow make an equivalent of WMAP for the neutrino background radiation, and observe the very early universe directly. I hope I live to see that!

If you can avoid traveling in normal space-time, then you've just potentially solved the problem entirely.

That doesn't help in the least. It doesn't matter how you travel: two events, separated in space, that happen "at the same time" in my frame of reference don't do so in another. If I depart A and arrive at B "instantly" in some reference frame, then I have travelled backwards in time from another. There's no getting around that: we live in a relativistic universe.

You seem to think the QM guys cooked up this really weird story while particularly high one night, then went looking for a way to make it fit the universe. It's the observations themselves that bring the weirdness. Sure, the universe at these scales far from human experience doesn't fit with our intuitions, but that shouldn't surprise, as our intuitions are based entirely on human experience. Sure the math is intricate, far from simple or elegant, but there's no actual reason to believe the universe is simple and elegant, other than it would be nice if it were so.

Is this all some complex expression of some simpler, underlying truth that we just haven't found yet? Certainly everyone working in the field hopes so! But the horrible, crufty Standard Model just keeps making accurate predictions, and all the clever ideas of physicists to create a simpler underlying model that could explain everything we measure keep failing to do so.

It seems like you're missing a key concept here: "simultaneous" depends on reference frame. If two events separated in space, A and B, happen at the same time in my reference frame, there's a reference frame in which A happens before B, and a reference frame in which B happens before A. There's no one true order of events.

This causes no paradoxes in relativity, precisely because you can't send information, or cause an action, faster than the speed of light. The propagation delay between A and B ensures cause precedes effect in every reference frame, and the order of events can't quite shift enough to overcome that propagation delay.

But moving FTL breaks all that. If I move "instantly" in my reference frame, then there's a frame in which I move back in time, and a frame in which I jump forward in time. I don't move back in time in my own reference frame, sure, but I really do in another. And if you're moving quickly relative to me, I can use that to relay a message from you to your past self - either by a series of accelerations between the frames, or by using a friend in your reference frame who can teleport as well.

If I want to visit my own past self, I would need to teleport some significant distance, accelerate up to relativistic speed, again teleport a significant distance, then accelerate again to match location and speed with my former self - elaborate, but possible. Or, if I could travel a great distance, say 1 billion light years, "instantly", then I don't need much acceleration at all, just the difference in velocity the Earth achieves in 6 months as it makes half an orbit would do it.

Comment Re: Do not (Score 5, Informative) 133

In addition to being cool stuff, mercury also has a very long history of use in gold extraction. I don't know about the people who built this particular structure; but mercury-amalgamation gold extraction is known to have been in use in South America well before the Spanish showed up. Given the human enthusiasm for gold, that's another point in mercury's favor as a funerary good, along with being weird and cool looking.

(Large scale extraction is now usually done by cyanide leaching, since that's somewhat less nasty than mercury amalgamation; but small scale miners often still use mercury. As one might imagine, the 'now heat the amalgam with a blowtorch to drive off the mercury and recover the gold' step is about as good for you as it sounds, possibly worse.)

It obviously can be done, the question is whether it makes financial sense. It seems that, if it were cost-efficient to store electricity in LiIon batteries then the biggest buyers of them would be power companies, so maybe there's some market inefficiency that you can exploit by doing it in customers houses, but it even with that it sounds like it will have a very long ROI. I pay about £400/year for electricity (about $600). A $13K battery storage array would cost me the same as almost 22 years of electricity. Even if it reduced my electricity bills to zero, it would take 22 years for it to pay for itself. I think the overnight rate, if I switch to a tariff that has one, is about half of the normal rate, so it would actually take 44 years. Probably a bit less as electricity prices are likely to go up over the next few decades, but even with a 20 year ROI there are far better uses of my money.

Comment Re:UK ISPs cause DoS (Score 1) 160

Lawsuits don't have to be expensive, it depends on how much you're asking. If you claim, say, the cost of one year of Internet subscription then you're in the lowest bracket for small claims court filings (plus your time, which may be a lot more depending on how flexible your working hours are). The cost for the ISP to send someone is more than they're likely to lose, so you're very likely to get a default judgement against them. For added irony, you might ask for the ISP to be required to pay for you to transfer your subscription to A&A and pay the difference in the cost of Internet access for the next two years...
