Title: Moon librations
Post by: Kingcosmo7 on October 15, 2008, 03:09:39 PM
In FET, the Moon does not rotate. But then why does it liberate?

BTW liberations of the moon is where it "wobbles" so that you can see 59% of the moon from earth. (not all at once)

Why couldn't the FE moon experience libration?
Are you asking what causes it, if rotation doesn't?

yes, because I just got off from a thread about the moon phases, and apparently the moon doesn't rotate in FET

[FEer]
We can't answer that question because we don't have the money to conduct research on something as complex as the nature of the Moon.  We don't even have the money to make a map yet, but you expect us to know something about the nature of the Sun, Moon or stars?

The moon is probably shaped like a dinner plate viewed from the bottom.  Mostly flat, but with edges to keep the magical liquid from spilling off the other side.

I would have figured that would have gotten some sort of response by now.

I wonder why the "real" FEers on this forum don't seem to want to explain this.  I realize that it probably might have something to do with the fact that there are no "real" FEers on this site, only REers who think it is more fun to play the Devil's advocate (i.e. OBLSteve).

So the FEers are ignoring the original question because of a typo?  That seems rather closed minded.

How about if I rephrase the question?

In FET, the Moon does not rotate. But then, what causes libration?

Does that make it easier for FEers to answer with it spelled correctly?

Not what I meant.  There are a lot of silly threads on this forum, and when I first read it I thought the OP really meant some type of moon liberation.

Librations is the proper spelling for the plural of libration. IE more than one libration. If I got here late, I can assure you it's spelled correctly now.

There is no FE response purely because there is no existing FET response that can explain lunar libration. Hell, some FE'ers still assert that the moon is flat. A flat moon cannot librate.

Sun spots are going to do for the sun what lunar libration did for those FE flat moon theories though. Osama bin Steve says they're just small bodies orbiting the sun, which he asserts is still flat... A downward facing flat body can't have easily definable and recurring circular/elliptical orbiting bodies though, and even if it could, those bodies wouldn't show in the way spots and kernels do on the sun... IE on it's surface, and not orbiting above.

This is from this (http://www.boston.com/bigpicture/2008/10/the_sun.html) awesome article on the sun.

This shows 6 days of the suns 25 day rotation. I can use cues in this image to make assertions that the sun is not flat, and is in fact spherical. If the sun is spherical, and the moon and all other planets and their orbital bodies are spherical, that leaves the earth odd man out in FET. "Chicken-sheep", and "They're just different" arguments are insufficient to explain why the earth is the only flat planet among it's exclusively round brethren.

Did you have a theory on what causes lunar libration in FET, or were you just testing Kingcosmo7? In FET is seems like it would need a focal, and libration is not phase or seasonal dependent. IE that focal is not the sun, and not the northern attractor. Lunar libration in RET is caused by eccentricities in the moons orbit. It's extent can last for a lunar cycle like the wiki anim, or longer-shorter durations. Under ideal conditions a libration could last several months. I'm not saying that's likely to happen any time soon, but I'm not saying it's unlikely either. If I did, it'd happen just to prove me wrong. Murphy's Law always takes precedent, and Murphy's law has never been my friend.

Roughly spherical.

So, it's what? An ovoid? Egg shaped? Which is it? Or does it just change shape whenever? I thought you guys said it was a "spotlight". If so, why does the image not change to an oval shape due to perspective the farther you get from it or it gets from you? And don't pile on the Magic Bendy Light BS, it won't fly.

By the way, what powers this "spotlight"? What's the type of light in it? Halogen, Xenon discharge, mercury vapor or maybe incandescent? What happens if the electric bill isn't paid? Do our crops fail, bats come out 24 hours a day and not get any rest?

And no, I am not being sarcastic. I can answer the same kind of questions, I learned them in highschool. The sun is spherical with a very slight ovoid shape do to rotation. It's energy comes from the fusion of primarily Hydrogen into Helium. It rotates it about 26 days. It is a main sequence star that is about half way through it's life span. It's is a Yellow dwarf. The Earths orbit has approximately a 93 million mile radius.

The only equivalent answers given by the flat earthers is; bendy light, it just is, it's not for us to know and hints that it's magic.

It isn't possible for anything to be a perfect sphere. The Sun most closely approximates a spherical shape, of all the regular three-dimensional objects.

If you're going to dismiss the bendy light theory, at least provide reasons why it won't work. I could just as easily dismiss parts of RET without explaining why they aren't true.

By the way, what powers this "spotlight"? What's the type of light in it? Halogen, Xenon discharge, mercury vapor or maybe incandescent? What happens if the electric bill isn't paid? Do our crops fail, bats come out 24 hours a day and not get any rest?

Direct matter to energy conversion by an unknown mechanism.

And no, I am not being sarcastic. I can answer the same kind of questions, I learned them in highschool.

I bet they also told you that electrons in atoms are like planets in the Solar System in high school, didn't they?

The sun is spherical with a very slight ovoid shape do to rotation.

Apparently one of the things you didn't learn in high school was the rules of English grammar. Also, if it has a slight ovoid shape, it isn't spherical. Try not to contradict yourself so much.

It's energy comes from the fusion of primarily Hydrogen into Helium.

"Primarily"? Tell me, what other fusion process goes on in the RE Sun? I'd be very interested to know.

It rotates it about 26 days.

Not all of it.

It is a main sequence star that is about half way through it's life span.

I could quote things I've learned verbatim too, but that doesn't make for a very interesting debate. Think more.

It's is a Yellow dwarf.

lol

The Earths orbit has approximately a 93 million mile radius.

According to RET, that is correct. Wikipedia could tell you that. What is your point?

The only equivalent answers given by the flat earthers is; bendy light, it just is, it's not for us to know and hints that it's magic.

FET is still a developing theory. Just because we don't have all the answers doesn't mean we aren't searching for them.

Still believing what you learned in high school? Deuterium-3Helium and CNO cycle fusion reactions are both present in the sun. The proton-proton chain dominates, but is not the only reaction going on.

Deuterium is a form of hydrogen. Though if the CNO cycle is indeed present, I stand corrected, and I do apologise. I thought that the CNO cycle only manifested itself in the red giant stage.

Deuterium is a form of hydrogen, but it can fuse with 3Helium. And you're almost right: the CNO cycle dominates in heavy stars (not always red giants), and the proton-proton chain dominates in the sun.

Lasers work, in a very basic sense, by bouncing a beam of light in between two mirrors, energizing it as it does so, until it reaches a sufficient level of intensity. If there was some kind of incredibly strong upward acceleration of light, then a laser beam would be smeared out inside the laser.

Of course, there's also the point that it goes against the main argument for the Flat Earth model, that the Earth has no visible curvature.

I have yet to see you spell out how you believe light bends. I suggest you open a new thread.

It bends up, with constant concavity.

Lasers work, in a very basic sense, by bouncing a beam of light in between two mirrors, energizing it as it does so, until it reaches a sufficient level of intensity. If there was some kind of incredibly strong upward acceleration of light, then a laser beam would be smeared out inside the laser.

Light only bends when the apparatus is many orders of magnitude larger than the wavelength of the light, similar to the way that quantum mechanics only applies on a small scale and relativity only applies on a large scale. You can't compare a laser to a long-distance light ray.

Of course, there's also the point that it goes against the main argument for the Flat Earth model, that the Earth has no visible curvature.

That doesn't make it any less plausible.

So you disagree that the Earth is round? Those results are just as convincing an argument for bendy light as they are for a Round Earth. Why do you assume that it is the Earth that curves and not the light? Is it because you have some other way of determining the shape of the Earth, or is it because you've been brainwashed into thinking that Round Earth is the default, and anybody who thinks otherwise is wrong until they can prove themselves to be right?

The wavelength of visible light is about 400?700 nm. All lasers I know of are far, far larger than this.

Because a round earth is a simpler model than a flat earth with an unknown force bending the light. By Occam's razor, a round earth model is better.

It would have to be many orders of magnitude larger - say, a few million times larger at least. Though I suspect this factor is not quite so large for radio waves, perhaps because their wavelength is too large for quantum effects to have a great impact on their motion anyway.

Because a round earth is a simpler model than a flat earth with an unknown force bending the light. By Occam's razor, a round earth model is better.

You claim there is an unknown force behind light bending, so I will assume from this that you know how the Earth ended up being round. So, let me pose the question: how is it that the Earth ended up being round?

I didn't say that.  I said that your arguments for bendy light are not convincing.  I accept that light can bend due to refraction as it passes between different media and that light can bend due to intense gravitational fields.  I have seen no compelling evidence for light bending due to any other cause.

And yes, you are wrong about the earth being flat until you can prove yourself right.  You haven't yet.

The laser in a CD-ROM drive is several million times larger than the wavelength of the light it emits. Most other lasers are larger still.

Also, it's due to quantum effects now? Is there any basis for that? I don't recall any part of quantum mechanics that accelerates everything upwards.

It doesn't bend due to quantum effects, but quantum effect cause it not to bend over short distances. Also, several million times larger than 400 nm is about a metre. Are you trying to tell me that CD-ROM drives have a laser that is a metre long inside them? I'm not talking about the beam itself, but the apparatus which generates it.

It's due to Dark Energy, and you are correct that we don't know exactly how it works. I'm asking you how your theory is better, that is, if you can explain what makes the Earth round any better than I can explain how light bends.

You're saying 'many orders of magnitude larger - say, a few million times larger'. I'm not seeing any accurate figures here. I can't see a couple of orders of magnitude change making a difference when the measurement is 'Many orders of magnitude'.

It also doesn't solve the problem of how lasers that are a meter long work.

The round Earth model has one force making the Planet spherical, so that it looks spherical. We don't currently know exactly what makes this force work. The flat Earth model has a force accelerating the planet up, making it flat. It has another force accelerating light up at a faster speed. We don't currently know how either of these forces work. The round Earth model is better, as it has less unknowns.

Post by: Parsifal on November 05, 2008, 07:53:22 AM
The argument is that light within the laser apparatus itself would need to travel in a straight line. Therefore, if the laser apparatus is small enough, the laser can still be generated correctly. Once leaving the apparatus which generates it, however, the laser is prone to the effects of Dark Energy if it travels for more than a metre or so.

You haven't explained how "quantum effects" keep the laser beam straight.

You're using quantum mechanics like a science-fiction author would: as a handy piece of technobabble to explain why your theory doesn't seem to work at small scales, and assuming the reader won't know any better. Unfortunately, there are people on these forums (me included) who have studied QM.

The largest laser apparatus that I have personally see is the one at the Ontario Science Centre in Toronto.  They have (or at least had as of about 10 years or so ago) a rather large gas laser apparatus.  I don't remember exactly how big it is, but it was probably in the 1-2 meter long range.  It was also high enough energy to burn wood quite nicely.

Now Steve, what kind of bendy light experiment(s) would you propose that they conduct on that device?

So are you saying that if I used the laser out of a CDROM and shone it towards the horizon that it would not bend?

If it would bend, then you can do an experiment in your own home. Simply place two mirrors several meters apart (as you said the scale you would need is about a meter to avoid the quantum effects), or even 100 meters apart and bounce the light back and forth between them going form one side to the other (not up and down).

You should be able to use basic maths to figure out where the light beam should leave the two mirrors based on how much you think light bends and the distance the light travelled (which can be calculated by multiplying the number of reflections by the distance between the mirrors). Or more simply, using another laser to shine directly across the mirrors (as it is not travelling as far, if Bendy light is true, then this beam would not be at the same height as the first laser beam).

In fact, this could easily be done for less than $100 (for an apparatus about a meter or two long). All you need is two laser source (the laser pens would be cheap enough, if you can get the green ones cheap enough this would be better as their wavelength is much smaller than the red light ones and so would further decrease you problem of quantum mechanics), a flat piece of wood (use a sander to get it really flat), two mirrors and some things to fix it all together.

It would also only take a weekend to make and perform the experiment. Have fun with it.
