Lets do a experiment. Go out and find a large rock, say 50 pounds.
Now do a thought experiment, predict whether or not it will fracture your foot if you drop it. Or will it somehow defy physics and spare your tootsies. Empirically speaking we only know what may happen. Science makes predictions based on facts and evidence. What do you think will happen, and why? If you are ardent that science is a inferior way of gathering knowledge, then you should have no problem dropping the rock with a hope and prayer the outcome will be favorable. Please let us all know how it turns out. "You were not there for the beginning. You will not be there for the end. Your knowledge of what is going on can only be superficial and relative" William S.

Where have you shown mathematically that the speed of light was the same 168,000 years ago as it is today? Give me the post. I will evaluate it, and will determine if you made any unsupported assumptions in coming to that conclusion.

Do you remember Message 5?
We dealt with the speed of light issue way back then. E=Mc2. If you change the speed of light you change Energy. We have radioactivity decay rings from the Oklo reactor going back 1.5 BILLION years. Yes, billion. Those decay rings match decay rings made today. Ergo; the speed of light has remained the same for at least the last 1.5 Billion years based JUST on the evidence found here on Earth.

I'm sorry, but your conclusion doesn't necessarily follow from your evidence, no matter who badly you wish it to be so.

Of course my conclusion follows directly and only from the evidence, that is one of the nice things about this example; like the proof that the Biblical Flood never happened it is simple.
The equation is really simple, only three factors; energy, mass and the speed of light. We have radiation rings (spheres actually) from the Oklo reactor that we can compare to radiation waste from today. For each element, the spheres are the same as they are today. As explained in Message 5: quote: E=mc2. If you want to keep the energy the same you then need to change the mass and that was dealt with in Message 20. quote: So we can say with a very high degree of confidence that mass has not changed at least for the duration of existence of this solar system. And that covers all the parts of E=mc2. Unless and until you can show comparable evidence to what I have presented, the conclusion does follow from the evidence. It's possible to imagine a Universe where the laws and constants are different than here, but it's impossible to have THIS universe. But maybe you want to speculate on some form of accelerated radioactive decay? Well that too would leave evidence. First, Oklo shows that accelerated radioactive decay did not play a part. How can I say that with confidence? Well, accelerated radioactive decay has been observed and the evidence documented; consider Bikini Atoll, Hiroshima, Nagasaki, all of the Nevada tests. Change leaves evidence Now, if you want to say "Despite all of the evidence I will simply believe in magic", then that's fine, but this is over in one of the science forums and here you are expected to either present evidence or reasoned logic to support your position. What you need to do is explain how mass can be changed and leave the solar system as we find it today; how the speed of light could be changed without changing the radius of radioactive decay spheres; how radioactive decay could be accelerated without leaving evidence. It's a tough challenge and so far no one has ever been able to do it, so don't get too disappointed should you fail. Anyone so limited that they can only spell a word one way is severely handicapped!

Hi foreveryoung,
While I can't give you a mathematical calculation (and frankly I distrust math in lieu of evidence), what I can do is give you some of the ripples of results that would occur -- see SN1987A -- part 2: correlations with the speed of light (Message 109): quote: Read Message 109 for the information this conclusion is based on, and reply to that.

Hi godsriddle,
It would appear that reading comprehension is not your strong suit. Please go back to SN1987A part 1, and if you have trouble with the math have someone who understands basic trigonometry try to explain it to you. You may also want to play the game a couple of times. Once again I will not waste my time on the rest of your babble until you deal with the reality of the actual measurement of the actual distance to sn1987A in a rational manner.

Hi again godsriddle
What I have done is given you some of the ripples of results that would occur if there was a change to the speed of light -- see SN1987A -- part 2: correlations with the speed of light (Message 109): quote: Please read Message 109 for the information this conclusion is based on, and reply to that. So far all you have done is wave your red herring fallacies in order to avoid dealing with the results of changing speed of light on actual observed data. Curiously I see very little reason to discuss things with you without you making some effort to deal with the issues I have raised. You can continue to exhibit conflict avoidance behavior and ignore the evidence of reality if you want.

If you halve the speed of light the energy in a given mass is not half, it is only a quarter of what it is now. But where would that show up? In stars of course for one example, but also right here on earth. A great example is the natural nuclear reactor at Oklo in Gabon, Africa. There is an example of a natural nuclear reaction that took place about a billion and a half years ago and that went on for hundreds of thousands of years. It produced waste much like what is produced today in modern nuclear reactors and that evidence can be examined to see what energy levels were involved. How? One way is by looking at rings produced when various elements radioactively decay. The energy level produced by the decay of a given mass of an element determines the energy level of the particle produced and that energy level determines how far the particle travels before it gets absorbed. The fact that particle emitted by a given isotope of a given element always travels the same distance before being absorbed so that concentric shells are formed is evidence that the energy level of that reaction has remained constant throughout the time involved to create the rings. When we look at a uranium or radon halo from 1.5 billion years ago it is identical to a uranium or radon halo created today. The idea that the physical laws were different at anytime during the existence of the Earth has simply been refuted. It may well be possible to have a functioning universe that has different basic laws but it is not possible to have "THIS" universe if the basic laws were different. E=mc2. If you want to keep the energy the same you then need to change the mass and that was dealt with in Message 20. quote:Back in Message 11 foreveryoung said:
So what difference would that make? First, none of us would be here and there would be no star sitting at the center of this solar system. HUH? How can that be true? Well the mass of the Sun is currently about 2 x 1030kg. If the mass was "less by an amount equal to the square root of its former value" what would the effect be? Well the mass would be √2 x 1015 or 1.4 x 1015kg. Now that's still a really big number, BUT, how big is it? Mass of Jupiter = 1.9 x 1027kg. Mass of Saturn = 5.7 x 1026kg. Mass of Uranus = 8.7 x 1025kg. Mass of Earth = 6 x 1024kg. Mass of Mars = 6.4 x 1023kg. It's less than the mass of Jupiter, of Saturn, of Neptune, of Uranus, less than the mass of the Earth, even less than the mass of Mars. Jupiter is too small, has not enough mass to become a Sun. And all the others are real lightweights compared to Jupiter. So IF the assertion above was true, there would be no sun, likely no solar system, maybe something like the Oort Cloud at best. It's possible to imagine a Universe where the laws and constants are different than here, but it's impossible to have THIS universe. So we can say with a very high degree of confidence that mass has not changed at least for the duration of existence of this solar system. And that covers all the parts of E=mc2. Unless and until you can show comparable evidence to what I have presented, the conclusion does follow from the evidence.

Now we look at how this compares to observed data: Light Frequency and Absorption LinesDifferent elements radiate and absorb light at different frequencies, frequencies that are specific to each element due to the atomic structure of each element. The frequencies are measured in wavelengths, but the waves are composed of particles, photons, that are emitted from the star in question. http://en.wikipedia.org/wiki/Emission_spectrum quote: Now the question is, what should we see if the speed of light was much faster when the supernova actually occurred. When we look at the peaks of wavelengths, the photons would be travelling much faster as they leave the star, but each new peak is delayed in departure compared to the previous one, as per the new board game above. The measured distance between peaks (ie wavelengths) from SN1984A is within the current visible spectrum: http://www.eso.org/public/images/eso9944b/ quote: For the wavelength at the star, due to the changes in the speed of light, this would have to be within 479/16.8 = 28.5 nm to 682/16.8 = 40.6 nm - at the most - to appear to be within the visible spectrum when observed on earth. It would actually need to be less as this is based on the average speed of light and not any decay curve for the speed of light. No elements have been observed emitting light in wavelengths this short, so the physics of light emission need to be changed as well as the speed of light. Not only that it needs to be done so that each elements emission spectrum exactly matches what is observed today. For example, this is the emission spectrum of Iron:
http://adsabs.harvard.edu/abs/1988ApJ...334..308B quote: http://www.nature.com/...ournal/v331/n6156/abs/331505a0.html quote: So there are a lot of emission spectrums that match those of elements on earth that need to be accounted for. Not only that, however, for if the star is still producing photons at these accellerated rates - and there is no reason to think otherwise if only the speed of light is changed - then as time passes we should see a blue shift in all stellar light. This has not been observed. Thus another mechanism is now needed to change the rate of photon emissions over time.

That reminds me of something that the late Dr. Henry Morris, "Father of Flood Geology" (even though he lifted a lot from George McCready Price without attribution) had written about residence times. Though he didn't call it that, since he didn't know what he was talking about. You see, as certain elements and compounds enter the oceans, they are also accreting out of it, such that there is an average amount of time that they remain in solution, their "residence time". This is the basis of the bogus creationist "sea salt" claim. Morris noted that the residence time of aluminum is 100 years. Now if we were to apply the logic of the case that Morris was building, then the seas could be no older than 100 years, which would mean that they could not have existed when in 1492, "Columbus sailed the ocean blue". Right? Morris' reaction to that bit of evidence that completely contradicted his claim was something to the tune of "Huh? I wonder what that might mean?" It's classic. We need to learn from the classics. As for the rest, you appear to still be waving your hands. I already described what happened when the mighty Kent Hovind just waved his hands about solar mass loss. You do need to do better.

Thats all great, but there is no resemblance between what I said and what morris said. I also did no hand waving. I have no idea why you said that.

Then perhaps you could explain your position. Rather than wave your hands.

Because this entire thread has been an exercise in hand waving. You posit a change in physical constants, but you give us no reason to suppose that there ever was any such change. You say that the speed of light could have been different. When it is pointed out to you that this would leave evidence, you imagine a scenario where mass changes by the exact amount needed to obscure the evidence. You are essentially arguing for us to believe in a change in physical constants on the basis of no evidence whatsoever. In fact, you are effectively claiming that you do not need evidence. You keep claiming that your conclusions follow from the evidence. Well how can this be when the scenario you posit leaves no evidence? The evidence makes the earth look old. That is where the evidence leads us. There is no other evidence. If you want to fantasise about magically warping physical constants, be my guest, but you can't claim that it follows from the evidence because the central plank of your argument is that it would leave no evidence. What you are doing is not "following the evidence". What you are doing is attempting to shoehorn your pet hypothesis onto the evidence and, when it doesn't fit, you claim, completely out of the blue, that it must have fit at some point, and that the very laws of physics warped to allow this conclusion. Then you declare victory. Well I'm sorry, but that's just not how rational enquiry is supposed to work. If your amazing shifting physical laws left no evidence of their change then there is no reason to believe they ever changed at all. Your argument does not follow from the evidence ('cos there ain't any), it follows from your desire to rescue Genesis from being so woefully, hopelessly wrong. If you weren't interested in forcing Genesis to make sense then you would never have come up with these ideas; you would have no reason to. The Earth would look old, the universe would look even older and you would have no reason to believe otherwise. The only reason you have a problem with any of this is because of the Book of Genesis. That is where your argument leads from, from a rationalisation that you are using to maintain your belief in science and your belief in a literal Genesis. The fact that you have to throw the laws of physics into the dustbin to do this should give you a hint of how doomed an enterprise this is.

Here's an HTML hint:
Well, guess what? That comes through as nonsense! Use the <SUP></SUP> HTML tags. One of the benefits of this forum is that you can mix HTML with BBCODES -- indeed, sometimes it's required. Using those SUP HTML tags, here is what your post looks like: quote: Do you see the difference that makes? Then please use it.
