What is the definition of life?
lajoswinkler replied to RAINCRAFTER's topic in Science & Spaceflight
Once again, you are either trolling or not being able to understand what I was talking about. I took an example and your job was to look at the greater picture. It's you who's thinking inside the box here. It doesn't matter if it's ATP or anything else. The point was the living thing is actively resisting to change its internal environment. It resists the change of energy and matter content. It's called homeostasis and it's the foundation of biological life. It's not an Earth thing. It's what makes life living. -
And I think some people should grow up.

The gap would grow horribly. I'm telling you, that would turn the society towards an actual SF dystopia. Even today, chronically poor nations, on average, have lower IQ, because lots of people grows up malnutritioned. If you don't feed kids properly in the first years of life, brains on average don't end up optimal. Now widen the gap with this and it gets very bad. Just imagine if vaccinations (great example, btw) weren't available to everyone by humanitarian help.

This is for pure water. For solutions of ammonia, which is expected to be one of the main constituents because it's so obvious and everywhere, things are a bit different. The graph depends on the molar concentration of NH3 in water, but as a general rule, increasing concentration will skew the graph's liquidus and solidus lines towards lower temperatures. At one atmosphere, solution with w=25% will have a melting point of -57.5 °C, and w=32% will have it at -91.5 °C, so at greater pressures, melting points are lower, but we must not assume there are concentrated ammonia solutions deep below. There is no reason to think it has to be the case. I'm still inclined to think there are liquid pockets down below even though surface regeneration by lighter volatiles seems to be the dominant process.

Opposite of utopia. It's not what I was talking about. I'd very much like for diseases to be eradicated. The problem is that humans are a horrible species that turns all opportunities into the worst shape possible before (if ever) realizing things could be done better. It would turn into castes. Increasing IQ, "beauty" (determined by some .......) and health combined for rich classes only... That would end up badly.

It is impossible for any of the ices there to experience a liquid phase on the surface at encountered pressures. You'd need five orders of magnitude more pressure to get the triple point. I couldn't find a carbon(II) oxide phase diagram, but here's one with data on methane and nitrogen. CO is very much like nitrogen. There might occasionaly be some precipitation in the form of very tiny particles in the atmosphere, probably forming parhelia like in this photo. Rate of falling would be abominably low. Direct ground deposition of atmospheric gases (reverse sublimation), therefore frost, is much more likely. I do agree that the mountains most likely aren't very young. It's the regolith, being transported around by sublimation and deposition, that should be the main reason for fresh looking surface. Impacts into Pluto would be spectacular because a huge amount of volatiles would turn into gas.

Wow, they're speculating radioactive decay as power source. Told you so.

The sickly, colorful, jawbreaker-like images are false colors. Channels are stretched, intensified, etc. The beige ones are LORRI plastered with RALPH data. Green filter is missing, so that info is extrapolated. It's as real as NH can make, but not 100% realistic.
-
Yes, that's LORRI allright. Amazing details!

What is the definition of life?
lajoswinkler replied to RAINCRAFTER's topic in Science & Spaceflight
That's why there are several levels of defining life. Would artificial intelligence be alive? Yes, but not according to the basic physiology. It's important to include conditions when definitions are made. Rock does not resist dispersal. It is absolutely passive. Ever heard of erosion? Dissolved acidic gases in rain such as carbon(IV) oxide will dissolve limestone. Result: karst. If you put a living cell into an environment it does not find optimal, like for example a hypertonic solution, it will not passively let itself into equilibrium. It will use its membrane motors to resist, shifting ions across the membrane to try to attenuate the loss of water. When it spends all of its energy storage (ATP), it will stop resisting and soon equlibirium will occur. Death. Of course, there isn't a special "force" that makes the cell behave like that. It does not go against the laws of physics. It's just a special system of coupled feedback loop reactions. Living things is resisting total equilibrium, and that's the key of biological life. -
Supercritical fluids at those temperatures and pressures are 100% lethal for any kind of organic molecule. If the organic chemistry can't happen down there, biochemistry can't either. As I've said, microbes could exist in thin part of the amosphere on Jupiter if they had enough nutrients coming at them, and their reproductive rate is balanced with mortality caused by Jupiter's gravity, pulling stuff down into its hell. If that isn't happening, population can not exist. The problem is that life can't form there. For self organizing structures to appear, you need very nice conditions for a loooong time. Also, they need an evolutionary mechanism (data storage and mutation source) to, by the hand of a "blind watchman", explore other niches of the environment. If the environment is wild, uneven, unpredictable, furious, things can't proceed further than simple aminoacids, alcohols, and other simplest stuff. It's how chemistry works. It's not "because that's Earth and that's space so therefore other rules apply". Chemistry has the same laws everywhere. 1) Arsenic based biochemistry is disputed. Completely. 2) Plankton does not live on ISS windows. 3) Extremophiles are organisms that evolved to adapt to specific niches. Put them in another niche and they die. "Extremo-" means something else, not "godlike". Now feel free to ignore the fact I just busted the foundations of your arguments and continue to build more wild ideas.

Shouldn't be that bad. There's always extra space just in case. No need for deleting stuff.

What Are Things You've Heard That Made You Facepalm?
lajoswinkler replied to michaelsteele3's topic in The Lounge
"I'm sick of these 'Pluto images'. As if a craft came there and precisely hit the spot where the planet would be in nine years. First of all, 'Space' is an imaginary thing invented by 'scientists' to hide the existence of God and to convince people there's something above Him. This morning I was talking to padre Miro who explained they watched footages and that you can see it was all done in a studio, and now someone is trying to show a craft went there. Pathetic attempt of atheists to deny existence of Lord and show themselves as allmighty. When Son of Human comes, will he find faith on earth? Luke, 18,9 Stop with these lies and admit you're tiny and insignificant compared to the Allmighty. God bless you." One of the Facebook comments I've translated to English. Seems the dude is not trolling. -
I really doubt that. It would mean NH was designed with too small amount of solid state memory storage. Remember that this was all planned. Every sequence of turn and imaging and scanning, it was all planned.

I'm staying awake.

"Large Planet Outside Pluto's Orbit"

You are lucky. You've managed to avoid one of the worst poops in the meadows of the World Wide Web. -
Mission specialist? does the are any rank among them
lajoswinkler replied to Pawelk198604's topic in Science & Spaceflight
I might be wrong but today, most of them are civilians. -
Remember, the left "heart" lobe is CO ice. Fascinating.
-
The "crater" is very messed up, and the "ejecta" isn't. That doesn't make much sense.

http://arxiv.org/abs/1507.03414 Observations of exotic structures in the J/Èp channel, that we refer to as pentaquark-charmonium states, in Λ0b→J/ÈK−p decays are presented. The data sample corresponds to an integrated luminosity of 3/fb acquired with the LHCb detector from 7 and 8 TeV pp collisions. An amplitude analysis is performed on the three-body final-state that reproduces the two-body mass and angular distributions. To obtain a satisfactory fit of the structures seen in the J/Èp mass spectrum, it is necessary to include two Breit-Wigner amplitudes that each describe a resonant state. The significance of each of these resonances is more than 9 standard deviations. One has a mass of 4380±8±29 MeV and a width of 205±18±86 MeV, while the second is narrower, with a mass of 4449.8±1.7±2.5 MeV and a width of 39±5±19 MeV. The preferred JP assignments are of opposite parity, with one state having spin 3/2 and the other 5/2. This has been a fruitful day for natural sciences.

It's not accurate as our eyes would see. The instrumentation lacks a green filter because of reasons. The difference is supposedly not that great, given the spectroscopy data. What you see is pretty accurate, although not really. It's kind of obvious. Looks too monochrome to me. Future images will be better.
