+ - Evidence of another world found on Moon 2

Submitted by mrspoonsi
mrspoonsi (2955715) writes "Researchers have found evidence of the world that crashed into the Earth billions of years ago to form the Moon. Analysis of lunar rock brought back by Apollo astronauts shows traces of the "planet" called Theia. The researchers claim that their discovery confirms the theory that the Moon was created by just such a cataclysmic collision. The accepted theory since the 1980s is that the Moon arose as a result of a collision between the Earth and Theia 4.5bn years ago. It is the simplest explanation, and fits in well with computer simulations. The main drawback with the theory is that no one had found any evidence of Theia in lunar rock samples. Earlier analyses had shown Moon rock to have originated entirely from the Earth whereas computer simulations had shown that the Moon ought to have been mostly derived from Theia. Now a more refined analysis of Moon rock has found evidence of material thought to have an alien origin."

It doesn't have to just beat the fallibility ratings of most humans though. It really needs to make less mistakes than, say, the top 1% of advanced defensive drivers to be acceptable.

If you believe you are a skilled driver and you make a mistake, I'm willing to bet you'll still come to terms with the mistake (and you can learn from it) much better than if you bought a self driving car and it makes a mistake that you know you wouldn't have.

Any mistakes a self driving car makes will cause media outrage anyway.

Also there are some driving Kobyashi Marus where whichever choice the algorithm takes, the driver is going to think it took the wrong one.

Also driving style is a very personal thing and there are arguably driving ethics. For example it's often taught not to brake or swerve for small animals but I'm sure millions of drivers will be disgusted if the self driving cars are coded to splatter the poor creatures on an empty road with clear visibilty at 30mph. Has this issue ever been addressed by the way? I've not heard it mentioned before.

The other problem (arguably greater in Europe than the States) is increased competition over land. As a local population increases due to a high birth rate and / or net immigration, individuals need careers to make a profit relative to their competitors so they can stake a claim to a patch of land to live on. If human population growth is expected to continue indefinitely, the competition over land will become more and more fierce so working hours and desire for income will not reduce. Population growth is encouraged because that's what fuels economic growth.

In the short term the "powerful people" are a problem too though as they keep the land and property prices propped up and encourage the population growth and competition. In the long term it will increase with or without them though.

Shouldn't the phrasing rather be something like "You can ask the frog one question, but every second day it lies, and every second day it tells the truth."

Now it is possible, but non-trivial, to formulate a question that tells you which door to use. (But not if the Frog is dead, though.)

I'd ask the frog "If yesterday I had asked you behind which door are the Riches and Power, what would you have said?" and then go through the opposite door.

Fuck beta as well.

Thanks very much for responding, Soulskill. I'm pleasantly surprised.

The one thing I can't get my head round is this obsession with increasing whitespace on new sites. I'm assuming it's connected with wanting to space out things people want to click on with their fat fingers on a small touch screen, but just increasing the size of buttons and links should do that.

I noticed even the current (classic) Slashdot site got its whitespace cranked up a lot a little while back, (I think it was sometime last year) around when the icons got redesigned, and people bitched about that even then.

Yes, I'm aware I'm not submitting this feedback through the proper channels. I guess you can put that down to a combination of cynicism, laziness and rebellious protest. I really feel it's something of a lost cause. This is the way the whole web is going.

Dice, Editors, your silence is deafening! Slashdot is News for Nerds but no true Nerd wants your Beta. Stop pretending this problem will go away. Maybe you actually hope it will go away, maybe you hope Slashdot itself will go away. Whatever - at least have the decency and respect for your long term readers to give some kind of response to all the negative feedback. Why not keep two versions of the site? If Beta was done properly it would all be a CSS skin with some scripts that could all be swapped out. You already have a mobile site, so it can't be to improve appearence on mobiles, tablets, phablets, touchscreens, etc. Oh sorry, I forgot, that wouldn't keep the advertisers happy. Slashdot was awesome while it lasted.

Thanks for your honesty but I abhor change for its own sake when it throws many of the great features of an old website. I've seen it happen so many times. Selling out to the mobile / tablet form factor with huge headings and everything spaced out and chunky. I don't blame the developers. They're building things to specification and have doubtless worked very hard. Reinventing the wheel for its own sake though when the new wheel is this unpopular - well sorry, I just have to let my frustration be known.

Dice have done far worse than kill Slashdot, they've hurt Slashdot and they intent to go on hurting Slashdot. They'll leave it marooned for all eternity in the centre of a dead fanbase ... Buried in whitespace ... Buried in whitespace ... Buried in whitespace.

Having said that it makes ME wonder how something created digitally would sound on vinyl!!

Don't you realise there's a whole LOAD of electronic music on vinyl? What do you think DJs in clubs were using? Some choose to do it without the vinyl now but it's still been the definitive medium for underground dance singles.

The thing is when work loathing people like that are forced into jobs, I think in many cases they will actually make their employing company worse off than if the position had remained vacant. An incompetent, work hating rebel can do a lot of damage when they're not being sacked and I'm sure there are thousands in large companies going un-noticed. They can cost the company financially and destroy the quality of the company's products or services. They can end up costing the economy more than the basic social benefits they could have been paid not to work.

You could add an extra 6km or so to that for every kilometre you could raise it off the ground, couldn't you? The tallest building right now is apparently 829.8m tall though I suppose the goal is to get it a uniform height from the centre of the Earth. Of course, raising it up means you have to build more of it versus just digging a tunnel underground.

I like work; it fascinates me; I can sit and look at it for hours.
