Comment Re:The water will be gone (Score 2) 183

He may be correct, so long as he was using the correct place to measure time. "Now" is dependent on your frame of reference, if the frame of reference is earth then "now" there is a metric fuck-ton of water around that super massive black hole, if the frame of reference is there then there may be "now," a lot less. Who know's what "now" via an earth based frame of reference +12 billion years will hold.

I mostly agree with you, however I was very impressed with the Chicago Electric cutting torch I got for $50. I used it almost everyday for 2 years in a shipyard, made better cuts than a $300 victor. It even worked after someone ran it over with a fork.

Comment Re:Typical U.S. quality (Score 1) 118

No, as a metal worker I can say that the mild steel, stainless, mag and aluminum that our shop gets from China is FULL of impurity. I can tell if the steel is from America vs. China / Mexico by the amount of crap that sticks to my tungsten. If after a rod of GOOD filler rod and no dips you need to re-grind your tungsten, it isn't a pure aloy. The issue gets worse and worse the more the more specialized the alloy. Having worked in airspace, if you don't dip your tung in the Al alloy you should NEVER have spit, and should have a weld stronger than the base metal.

That is unless someone has some fun with you.... Try a simple exchange of magnisum filler rod for Al. Welds the same, however the bead just falls off when done. If you try this just know when to run.

Comment Re:Automatic transmissions fail before engines, no (Score 2, Informative) 609

The difference is that when an automatic does go, the parts are more expensive and the job is more complex because there is no convenient place to put a point of failure. In a manual, the designed point of failure is the clutch pads. it is relatively simple to pull it apart and replace the pads. At most, in a well designed car like a Subaru, it is a 2 or 3 hour job. I've seen automatics take 2 days. At $90/hour for shop time the repair of an automatic means you eat ramen for a month, while the servicing of a clutch means you can have some steak.

Comment Re:Laudable, but misguided (Score 2, Insightful) 281

Earth may have resources that are "useful," however all the stuff we have on earth is found further out of the Sun's gravity well. Main belt asteroids have more heavy metals than earth, and you don't need to crawl out of a deep well to remove them from the solar system. And if you are only after water and gases, the oort cloud has more than enough that the cost to weight of getting the minuscule amount we have here on earth just isn't worth the energy. The ONLY reasons I can see for a hostile race to worry about humans is our technology (not likely if they are interstellar race), genetic mapping for bio war, to remove a possible future threat (the most probable reason I can think of) or, finally to colonize a planet in the "Goldie Locks zone." That last one has a lot of issues that may make it more beneficial to sterilize the planet due to biological contamination, and in that case mars would seem to be the better planet to transform IMHO.

In any other case I can think of, they would contact us and see what they could learn or teach us, or place a probe in the outer solar system to watch us. Not a lot of reason to worry about it all.

We get observed, first contact or death and there is nothing we can do to change it.

Well It is a good thing that planet hunters are better at finding things than you, seeing as they have found 358 extrasolar planets. From what I hear, it is much harder to observe the wobble of a star's red shift or see the wink of a star as a planet travels between us and it, than it is to break open a rock in a known trilobite bed.


Comment Re:Swell... (Score 2, Funny) 336

I've been prepping my sons (3.5 years and 7 months) for their first viewing of Alien/Aliens since birth by grabbing their entire face with my hand. They think its funny... at least for now.

This reminds me of when my parents took me to see Alien when I was 5. Good time had by all due to a weeks worth of sleep deprivation.

Comment Re:pffft! It's not "Supervolcano" (Score 4, Insightful) 180

The point is that the very large and active Mt. St Helens could be just a small vent for a much larger volcano. One who's crater / caldera is close to 2000 square miles. If true, something like this going off would make Krakatoa look like firecracker. As in, all of the US and a good chuck of Canada and Mexico covered with ash.
