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.

Evolution doesn't exist. It's a fairy tale for people. People believe, that the can develop, move on, that they are not at an impasse. But people are the same as at the beginning of their existence. They began to dress differently and live in other dwellings, established new laws and built a new city. But everything is new - it is well forgotten old. They are a little altered his life, but not moved forward even a step. People were deadlocked in their evolution long ago.

If I return all the way up to the OP, the claim here is that there is no evidence for evolution. Well, that's one big fat lie.

There's a huge lot of evidence that evolution exists and works, literally thousands of examples and experiment results. If I should name just one of all, there's nylon-eating bacteria. Nylon is a completely artificial material, no such material has ever existed on Earth before it was created by humans and when it was created, there was no organism on Earth that could digest it. But in a few years, some bacteria surprisingly started being able to digest nylon. If god created life at the beginning and there was no evolution, the bacteria couldn't have evolved to digest nylon.

The question whether the life has evolved from common ancestors or whether it was created by some kind of god is of course completely different question. Nobody can return back in time to check that, so what we're left with is evidence in form of paleontological finds, and our beliefs. In short, we can trust science, or we can trust religion.

In my opinion, anybody is free to believe all life and humanity was created by their preferred kind of god any time they consider suitable pretty much the same as anybody is free to believe there is an angel talking to them from their cellphone. The basis of both is about the same.

If matter, energy,time and pancakes were eternal, that means an eternal ammount of time would need to pass before us, so they can't be eternal.

If they aren't eternal they must come from another source, and I'm out of sources if I don't place God there.

That plus: Where did the first humans get the notion that their morals should agree with the commandments so that we have them today? The fact that you blush doesn't make those morals seem like something taught in the first place.

Let's go from this demonstration of the existence of God to the point of evolution, now. If there is somebody skilled to do it, of course.

Why not?

Try the "circle of wind" as described in Theravada Buddhist cosmology. There's just as much basis for it as there is for God, i.e. none.

> Where did the first humans get the notion that their morals should agree with the commandments so that we have them today?

You mean Judeo-Christian commandments like "thou shalt have no other gods before me?" The morals of Chinese, Japanese and Indian people certainly agree with that one.

The event horizon of a black hole is comparable somewhat to the event horizon of the known universe. The big bang apparently started from a single point which is comparable to a singularity. Imperfections in cosmic background radiation could be comparable to the imperfect distribution of matter entering a black hole. However this is not enough evidence.

http://en.wikipedia.org/wiki/Cosmological_horizon

For this theory to make sense you would need to make the outlandish speculation that time is going backwards in a black hole such that from the perspective of someone inside the black hole it is expanding from a singularity rather than going towards the singularity. There are various problems with this.

1: Light simply doesn't escape the black hole, nothing exceeds the speed of light and starts going backwards in time.

2: Once light or matter reaches the event horizon it is traveling in a straight line towards the singularity, I hear. It would be an eventless universe.

16 Name: !MYc/Bn0EAo : 2015-04-05 22:11 ID:BkjFEr14

also worth noting that time dilation increases as you near the event horizon, if the trend continues then in theory time would start going backwards

17 Name: Anonymous Scientist : 2015-04-28 09:25 ID:qx1EbzJt

But according to the mathematical model, time slows and stops. It does not at any point move backward.

We are living in a simulation (59)

1 Name: te-kun : 2008-04-11 22:29 ID:BePokpVk

  1. It is possible that a civilization could create a computer simulation which contains individuals with artificial intelligence.
  2. Such a civilization would likely run many—say billions—of these simulations (just for fun; for research, etc.)
  3. A simulated individual inside the simulation wouldn’t necessarily know that it’s inside a simulation—it’s just going about its daily business in what it considers to be the "real world."

Then the ultimate question is—if one accepts that theses 1, 2, and 3 are at least possible, which of the following is more likely?

a. We are the one civilization which develops AI simulations and happens not to be in one itself? Or,
b. We are one of the many (billions) of simulations that has run? (Remember point iii.)

either

1. intelligent races will never reach a level of technology where they can run simulations of reality so detailed they can be mistaken for reality (or this is impossible in principle); or

It seems to me that any accurate, large scale universe simulation is impossible as a matter of principle. The amount of energy it would take to run, having to simulate every particle in the universe realistically and simultaneously for trillions of years, would be as much or nearly as much energy/matter as there is in the universe. Otherwise the creation of such a simulation would violate things like the law of the conservation of energy in thermodynamics. So that the universe exists at all means that there is no simulation being run, meaning that if any "ancestor" universe exists it also cannot simultaneously exist AND run "our" universe, but we exist so it can't exist, or at least we are not a simulation.

Why would it necessarily need to be a large-scale simulation? If one wanted to study something specific (the evolution of societies) and one could run a realistic enough simulation of -that-, one presumably would only need to give the appearance of their being something more out there in the universe (esp. if one wanted the conditions to be similar to one's own universe in order to simulate something like one's own civilization).

Sure, and the one simulating that universe would have more energy available, and the one after that would have more energy, so on and so forth into an effectively infinite amount of energy. Doubtful and there's no reason to believe it's true or even probable, it's superfluous. The simulation of any expanding universe would take up almost the entirety of energy in the simulating universe anyway over the course of time, and we live in an expanding universe.

In practicing celestial navigation, one learns to think of the moon, planets, and stars not as places or even things, but as points of light projected onto a screen for our convenience...

For a lot of history, this was basically true. At this point, our most distant probes are only in the nearest suburbs of our home star. Due to the great distances involved, it becomes necessary to scale down the sensors due to the consumption/lack of power over time. We don't have pictures of the darkness out there, just a stream of numbers and that's not hard to simulate.

So anyway I guess what I'm saying is that you need to simulate at least solar system for this experiment. However you can get quite sloppy in the distant reaches of it if you make the rules of the simulation sufficiently hard (stupid entropy). Somehow I think as we gain the ability to travel further, this theory will become the simulation of the gaps.

Planetary Wind Speeds (10)

1 Name: Anonymous Scientist : 2010-07-22 20:26 ID:NfBu+1wR

Years ago, I watched a program that was talking about how wind speeds varied from planet to planet in our solar system. Eventually it saw a correlation between distance from the sun, and wind speeds.

Surprisingly, the further you got from the sun, the faster wind speeds became. My memory gets a little vague from here on out.

Basically, the program moved on to trying to model these speeds, and was succesful, but when it went to model earth in the same way, it showed that we should be having waaaay huger winds than we do experience.

At the end of the program, they showed that the solution to the progblem was that earth had it's ice caps, which for some reason I don't remember really cut down on our wind speeds.

i'd love to watch this program again if someone knows what it's called or where to find it.

Does anyone remember this one?

Well I looked up Venus's weather for the hell of it and apparently the winds on Venus will circle the planet 4 to 5 times in a single Earth day, whereas Earth's winds move at barely 10% to 20% of its rotational speed.

Lets contrast the atmospheric compositions of the two planets:

-Venus:
Surface pressure 93 bar (9.3 MPa) or 9300 kPa
Composition ~96.5% Carbon dioxide
~3.5% Nitrogen
0.015% Sulfur dioxide
0.007% Argon
0.002% Water vapor
0.001 7% Carbon monoxide

Not sure if this has something to do with but temperature and pressure differences between atmospheric layers maybe affect the wind speed, considering how tornados and such are formed here.

How fast does Venus spin on its axis? How fast is its revolution around the sun?

I'm thinking maybe since Venus is closer to the sun, the solar winds actually get to it? And by the time the solar winds reach Earth they're pretty much dissipated? I dunno. Astronomy and physics aren't really my thing.

Solar winds...? what?

Anyway, wind has to do with balancing the distribution of heat within an atmosphere. On earth, hurricanes/cyclones are basically heat energy flowing from the overheated tropics into temperate zones and tornadoes likewise spring from warm wet air meeting cold dry air. When two masses of air of varying temperature meet one another, bad things happen. Just bear this in mind briefly.

Every day, the earth rotates once. The surface will be exposed (on average) 12 hours a day over the course of the year. The other 12 hours a day (on average), we're in the shade. On Venus, things are quite different because the day there lasts 116 days. During this time, half of the planet is in daylight and the other half is in the shade. One half is having the worst summer day ever, the other half the worst winter day ever. You're going to get crazy wind as a result of the crazy temperature difference (relative temperature difference; Venus is on average hot as hell everywhere but moreso during the "day").

Turns out OP wanted the name of the program, not a discussion on this topic. Oops...

I use it to gain power in general, power gives you more options whatever your motivations. You might want to become biologically immortal, you might want to help alleviate suffering, but you can't do any of this without wealth or power.

Knowledge is useless if not wielded by the wise, and I am aware there is more to it than that. There is a kind of information economy, you need information about information to determine the chances of it being useful in the practical sense which presents an interesting dilemma, since now you also need information about information about information about information, there are some parallels with calculus, this sounds like borderline autism but I am not obsessed with this or anything, it is just an observation I have made, when it gets to this point I usually just rely on good old human common sense and approximations to make the best decision. For instance if I am looking up penny stocks and I come across a dodgy company dumping millions of shares on the market with red flags everywhere when I go to their site, I know there is no longer much point in me spending more time on this, I go to the next one. If I next find a biotech startup and there are no red flags I have to decide whether it is worth trying to understand the drug they are trying to develop myself, I have to try and determine how long it would take and the opportunity cost of spending time on it or researching more companies. Through these means I can figure out how to make reasonably effective use of my time, how to valuate companies, risk and returns and the opportunity cost of various options.

What if I told you that economics is a pseudoscience, and that all the phenomena you're trying to model in such painstaking detail are random chaotic herd behavior?

Internet, teach me math (8)

1 Name: Anonymous Scientist : 2013-04-06 12:35 ID:uq2x6m9z

I'm a cock sucking retarded mouth breather, where do I go to learn caclus and shit?
Waht's th SICP of math? What would you recommend, besides killing myself. I already know about khanacademy.

Any advice?

Btw I'm not learning lisp or reading SICP.

Try Khan Academy, d00d. From pre-algebra all the way up through calculus. Khan is the Man. It's free, too--free as in beer, as well as in speech.

Earth's Magnetic Field Polarity Reversal (11)

1 Name: Sling!XD/uSlingU : 2006-05-13 13:38 ID:Heaven

http://www.allheadlinenews.com/articles/7003537762
"The ships logs from the voyages of Captain Cook have yielded a new discovery: the gradual weakening of Earth’s magnetic field is a relatively recent phenomenon. The discovery has led experts to question whether the Earth is on track towards a polarity reversal."

"The field’s strength is now declining at a rate that suggests it could virtually disappear in about 2000 years. Researchers have speculated that this ongoing change may be the prelude to a magnetic reversal, during which the north and south magnetic pole swap places."

It happened before and it'll happen again.

3 Name: Sling!XD/uSlingU : 2006-05-14 23:10 ID:H4KHJW1C

I read Slashdot's take on it http://science.slashdot.org/article.pl?sid=06/05/13/1516234 and I thought they were awfully calm about it.
Wouldn't such an event create total chaos?

from Wikipedia:

Since a magnetic field reversal has never been observed by humans and the mechanism of field generation is not well understood, it is difficult to say what the characteristics of the magnetic field might be leading up to such a reversal. Some speculate that a greatly diminished magnetic field during a reversal period will expose the surface of the earth to a substantial and potentially damaging increase in cosmic radiation. However, Homo erectus and their ancestors certainly survived many previous reversals. There is no uncontested evidence that a magnetic field reversal has ever caused any biological extinctions. A possible explanation is that the solar wind may induce a sufficient magnetic field in the Earth's ionosphere to shield energetic particles even in the absence of the Earth's normal magnetic field [1].

I see.

http://en.wikipedia.org/wiki/Geomagnetic_reversal says
"Although the inspection of past reversals does not indicate biological extinctions, present society with its reliance of electricity and electromagnetic effects (e.g. radio, satellite communications) may be vulnerable to technological diruptions in the event of a full field reversal."

"may be"? So nobody knows what would happen? Or is it about the magnitude of a solar flare, i.e. not very serious?

The mechanism generating the Earth's magnetic field itself is not well understood, so nobody knows exactly what happens during a pole reversal. Electric and electronic equipment would probably be more sensitive to fluctuations of the field rather than the absence of a field. Lacking any information of what kind of fluctuations to expect, there's really no way to know what the effects would be.

I hope everyone will be ok except for the Earth turning into a global Van de Graaff generator. It would be both a potential extinction event and a new trend in fashion.

>turning into a global Van de Graaff generator.

That would open the door to Free Energy, at long last! :)
