Silicon based life, has anybody tried this? (5)

1 Name: Anonymous Scientist : 2012-04-21 07:52 ID:/D9C9Ntc

Basically it is a variation of the experiment performed by Stanley Miller and Harold Urey in 1952 where you take water vapor, methane, ammonia, and hydrogen, then run a current through it to produce simple amino acids. Only in this variation we would replace the methane (CH4) with silane (SiH4). Has this experiment every been attempted it and if it has what were the results?

2 Name: Anonymous Scientist : 2012-04-29 10:12 ID:onORqr+d

As it turns out Silane is highly volatile and reacts violently in air. Perhaps DiSilane (Sih6) can be used instead?

3 Name: Anonymous Scientist : 2012-07-14 17:03 ID:0cHiNp+q

In decades past there was considerable theoretical interest in the idea of silicon-based life, but it turns out that silicon does not behave quite exactly like carbon. Silicon-silicon bonds are not as strong as carbon-carbon bonds, so the sort of enormous and complex carbon-based molecules required by life as we know it (proteins, etc.) are unstable when silicon is substituted for carbon.

See also,

http://nai.arc.nasa.gov/astrobio/feat_questions/silicon_life.cfm
http://en.wikipedia.org/wiki/Hypothetical_types_of_biochemistry#Silicon_biochemistry

This is not to say that life evolving in an environment where soluble silicate and silane compounds were common could not have carbon-based biochemistry with bits of silicon-based compounds here and there that might have unusual and useful properties, but that is just speculation.

4 Name: Anonymous Scientist : 2012-09-20 20:17 ID:Ewm6MFEG

It's clear that Silicon atoms cannot be substituted for Carbon in our proteins, our DNA etc etc. But that does not mean Silicon cannot be base of some completely different life.

The main obstacle in my opinion is not only the fact that carbon is way more versatile in creating complicated structures, but also that it is way more abundant in the universe. For a silicon-based life to appear spontaneously, we would first need some mechanism creating planets with a lot of silicon and little or no carbon ... and quite probably "unnatural" concentrations of many more elements.

So maybe when our scientists master carbon-based abiogenesis in their test tubes, they may try to find out how to achieve similar outcome with silicon. But for now when it's not even clear what is needed for carbon-based life to arise from anorganic materials, it's a bit too early to try to construct it from silicon.

Defuse a volcano? (18)

1 Name: Anonymous Scientist : 2011-10-27 19:42 ID:Yc4D7ZOM

As this is the ever-highly speculative Science board, I put to you a highly speculative scenario: Are you a bad enough dude/construction company/government agency/super villain to stop a volcano? Can you think of a way to take enough energy out of the equation to make a volcano sputter rather than explode?

I say this with the threat of Uturuncu popping its top sometime soon and potentially messing with the weather even worse than Pinatubo did. Also, I'm all about job creation...

Don't hold back! I want to hear crazy ideas.

11 Name: Anonymous Scientist : 2011-11-28 17:40 ID:Yc4D7ZOM

>Beowawe Geyser Field was located in central Nevada between Elko and Battle Mountain. The field and steam were visible from the Interstate. The geyser field itself was located on the side of a hill and immediately at the bottom of the slope. This small basin was considered for national monument status, but apparently a political rivalry caused its disapproval. In the 1950s, geothermal drilling began the downward spiral of geyser activity at Beowawe.

The same thing happened to Steamboat Springs in Nevada.

Basically, drilling deep into the ground and using the energy from the earth killed geysers. Granted a volcano (particularly a big nasty explody kind) is many orders of magnitude greater in power, there's still potentially something to be gained from sucking energy out of the equation.

If you flood a volcano, it might not defuse it, but you can harness the resulting steam and use it for energy.

Anybody remember that episode of the Transformers where the Decepticons were draining off the heat of the Earth to fill their energon cubes and it got so cold that you could have a snowball fight in the desert in the middle of July?

15 Name: Anonymous Scientist : 2011-12-31 14:50 ID:veQXhOEn

If you injected a powerful agent to lower the viscosity of the melt, it would decrease explosive potential. You could heat up the melt a lot while simultaneously introducing iron or other heavier elements to lower the silica content, which would also lower the viscosity and decrease likelihood of powerful eruption.

To complete stop a magma chamber, you would have to bore into the magma and insert miles-long rods of a material with a really high thermal conductivity constant. This could be supplemented with a dessication (de-watering) compound to lower the solidus of the melt and induce crystallization.

Accelerating to orbital velocity will always be a rough ride if you do it by thrust alone. Orbital velocity is some 7000-8000 km/s, so the little bit of extra velocity you get from the freefall is pretty much nothing.

> 1. The aim of this report is not to question or to fight a belief – the right to freedom of belief does not permit that. The aim is to warn against certain tendencies to pass off a belief as science. It is necessary to separate belief from science. It is not a matter of antagonism. Science and belief must be able to coexist. It is not a matter of opposing belief and science, but it is necessary to prevent belief from opposing science.

Stopped reading there.

There is NO evidence of evolution. It is a belief. Objective science doesn't support evolution no matter how many frauds and hoaxes are fabricated to support evolution. The truth always trickles out.

Life doesn't just happen. That alone totally defies the Laws of Science.

The Judeo Christian G-D, made it happen. G-d is the Author of all science. It is no coincidence that leading evolutionists are atheists. THAT is by design. These atheistic evolutionists do not find G-d acceptable in their premises. Their premise is that there is NO G-D.

In the Old Testament, there are many references made to God leading the Israelites out of bondage in Egypt with a "strong hand and outstretched arm." There, reference to God's hand is clearly metaphorical, as he uses the plagues to free the Israelites, not a giant hand. God is a transcendent being, and thus does not have hands in the human sense. I think that the same is true of where it says in Genesis 2 that God formed man from dust he had gathered; God acts through the natural processes He created to carry out his will, as befits a being of His stature. However, the Bible occasionally using figures of speech should not be taken to detract from its spiritual truth.

If life spontaneously appearing defies the "Laws of Science", as you call them, what property of the entity you refer to as "G-d" allows it to create life, in violation of the "Laws of Science"? If this entity can circumvent the "Laws of Science", can they really be said to be laws? And if as you say this entity is responsible for the creation of life, does that not imply that the "G-d" entity is not itself alive?
