Comment Re:What complete nonsense (Score 1) 300

FWIW, there are diamonds in asteroids too.

Where did you ever get that idea? Diamonds are only formed under conditions you will find on a planetary body:

Most natural diamonds are formed at high temperature and pressure at depths of 140 to 190 kilometers (87 to 118 mi) in the Earth's mantle. Carbon-containing minerals provide the carbon source, and the growth occurs over periods from 1 billion to 3.3 billion years (25% to 75% of the age of the Earth).

Ain't gonna happen on an asteroid. A basic rule of thumb is that asteroids will only contain igneous materials, never sedimentary or metamorphic.

I suppose you think all roads should be toll roads and your bank account is auto-charged for each one you drive on?

Sounds like an awesome idea. It's not a new one, either. Private autos impose enormous external costs on society, amounting to a hefty subsidy for car ownership. There's no reason cars shouldn't pay their way in full.

That's just dumb, that's just dumb because you can't make a car smart enough to navigate daily traffic with all onboard sensors.

This is exactly how Tesla does it, and while it isn't perfect, it's mostly usable and still improving. It's silly to say something is impossible when we are already most of the way there.

Parent was being ironic.

here's what happened when Airbus built a fully automated airliner (with no human inside) and have it land itself:

This was not an automated flight, and was not unmanned: there were 136 passengers on board. Three people were killed, and 34 required hospitalization. The cause was pilot error, and the flight crew was convicted of involuntary manslaughter for pulling a stupid stunt with a loaded plane.

Use more rhetoric. Use more insults, make the conclusions more dire, and make the deadlines for action seem nearer and less attainable.

Funny how the same people who constantly whinge about "Political Correctness" and how much we need more straight talk, turn into delicate flowers when that straight talk is pointed at them.

People who still in denial about climate science are delusional nuts. Full stop. There is an actual reality out there, and those who refuse to accept that should be marginalized and ridiculed, and should be given exactly zero voice in policy.

Comment Good for China (Score 5, Insightful) 117

Good for China, and good for us: the sea level rises for everybody equally, no matter which country is at fault. Today, the U.S. and China emit vastly more greenhouse gases than the EU, India, and Russia combined. Those two countries have a responsibility to the rest of the world to get their houses in order.

China is doing something about it, albeit first steps. The U.S., by contrast, is being run buy delusional nuts who think global warming is some kind of scam. Makes me ashamed to be an American.

No dark matter is not just normal matter that isn't emitting light. It isn't absorbing light either. If 90% of the galaxy was just non-emitting normal mater you'd see it blocking the luminous modules as dust clouds and globules.

Um.

Things that absorb light also emit it, necessarily. Look up black body radiation sometime.
