Well this is where a distinction needs to be made between ASC and the ASC model. Lisle does give evidence as to why he believes the Universe is not billions of years old towards the end of the paper. It’s kind of a two pronged approach, why distant starlight cannot be used to contradict the Biblical timetable and what evidence actually supports the Biblical timetable.
Even if the Bible did make such statements about the Universe prior to the telescope people would not believe it. We find evidence all the time that seems to confirm a Biblical record but it is always simply waived off or a rescue mechanism is invoked.
Quote: How does it make sense to describe the passage of light from the perspective of something that has yet to be created? Doesn't it make more sense to describe events from the perspective of the creator? After all, humans were the last thing to be created on the last day of creation, so it would make no difference to them if the previous “days” were literal, relative or figurative.
It’s not describing the passage of light from the perspective of something not yet created because the Earth is created on Day 1 while the Stars are created on Day 4.
Quote: If Lisle assumes that the timing of creation “week” is relative to the perspective of humanity, why not also assume that descriptions of the Noachian deluge were written from the local perspective and that it was the known world which flooded rather than an actual global flood?
I would not say from the perspective of humanity, I would say from the perspective of Earth. As for the local flood theory it has some problems. A flood that covers the “highest mountain tops” is not going to remain local. Secondly, a local flood would not accomplish the goal of the flood (to destroy all flesh). God promises never to do it again, if this is a local flood he has broken that promise numerous times. Lastly, God’s covenant after the flood was with the entire globe.

You have been arguing for a young universe (or Earth, whatever) based on your interpretation that the speed of light (one-way, whatever) is not a constant. Here you are admitting that the velocity of light (be it two-way, or whatever - what we use in equations determining the standard candle) is a constant in a vacuum. This is an important admission since you cannot make this admission and then come to the conclusion that the universe is young. Hence my statement below:

Yeah, I get that.

On the contrary, the over-riding factor is still the duration of the alternate reference frame. Unless you're saying the positional time dilation is also subject to the rate of change, but that sounds rather like a change in relative velocity

Well a vehicle will use up the same amount of fuel for a given velocity regardless. All you have to do is compare the actual fuel consumption of the vehicle with that predicted from the position of an observer.

I’ll give you an example. If you had argued in the late 1980s that it would be possible to find soft tissue and proteins in dinosaur fossils you would have been laughed out of the room. The fact that we had never found any such thing was considered strong evidence supporting the notion that dinosaur fossils were millions of years old. Based on the empirical evidence such tissue degraded far too quickly to ever be found in fossils older than a million years. Then in the mid-1990s surprise! Soft tissue and proteins were found in dinosaur fossils. Not only this, but now it seems that they are found whenever we actually look for them. Rather than arriving at the obvious conclusion (such fossils must be younger than a million years old) the old Earth community simply said, “Well I guess DNA can last for 65 million years.” They can always come up with an ad hoc means of saving their paradigm.

These people are all descendants of the eight survivors of the Genesis flood. What you are seeing are corrupted accounts of the same event. Since these accounts were not divinely preserved unlike the account in Genesis we would expect differences because people change stories as they pass them down. I will give you an example. After the Titanic incident there were people who swore the boat broke into two pieces while in the process of sinking. There were other people who swore that the boat stayed intact all the way down (we know the ship broke we just do not know when). Now this is a huge discrepancy seen in people who experienced the event themselves. Now compare this with people 20 generations out from an event and you’d expect great differences in the stories. There are some very significant similarities in the flood accounts though. One of the Australian accounts is very similar to the Genesis account (Gajara was told to build a vessel for himself, his wife, his sons and their wives. The flood covered the highest mountain tops. He released birds to see when land was available. They made an offering to God after the flood. God placed a rainbow in the sky to prevent future flooding.); yet aborigines are supposed to have been isolated as a people group for a very long period of time.
Quote: If, on the other hand, these other myths are referring to different floods, then why does the bible not tell about these other global floods? If they occured but were not the noachian flood then the biblical account is wrong - unless of course god lied.
People are fallible and therefore stories change as they are passed down.

It is not the fact that we can see stars that is used against your timeline.

The velocity of light in a vacuum is a constant, warped one. This is not an ambiguous statement. It is a statement of fact. Standard candles are used to determine the distance to astronomical objects such as stars and galaxies. They are measured in parsecs and also in LIGHT YEARS. The distance, based on these measurements, from one end to the other of our own galaxy is 100,000 light years, which means it takes light 100,000 years to reach from one end to the other. This measurement alone refutes your Bedouin timeline by an order of magnitude. And that is just the diameter of our galaxy, which is one of over 100 billion galaxies that exist in the universe. The KNOWN age of the universe, based on these measurements is 13.7 billion years. This is also not an ambiguous finding.

No sir, I am not. The distance that light travels in a year is used as a ruler to determine not only the size of the universe, but its age. You would have to be very poorly educated (or willfully ignorant) not to be able to solve for time from the units of measure used in these equations (such as m/s, or light year). As for your last statement, above, I have yet to see you demonstrate how you get a 10,000 year old universe out of evidence for a 13.7 billion year old universe.

In the example given, Clock 2 is travelling at half the speed of Clock 1, but the RTF experienced by Clock 2 is qpprox. a quarter of that experienced by clock 1. So even though Clock 2 is travelling for twice as long, it still only suffers approx. half the time dilation overall. Obviously, Clock 2 travelling for twice as long and suffering half the time dilation is just a quirk of the example given - at higher speeds the difference is much more pronounced.
E.g. If clock 1 travels at .96 c and Clock 2 travels at 0.48 c, Clock 2 still has twice the travel time but Clock 1 experiences more than 3x the RTF (Clock 1 = 3.5714 and Clock 2 = 1.1399)

Quote:I’ll give you an example. If you had argued in the late 1980s that it would be possible to find soft tissue and proteins in dinosaur fossils you would have been laughed out of the room. The fact that we had never found any such thing was considered strong evidence supporting the notion that dinosaur fossils were millions of years old. Based on the empirical evidence such tissue degraded far too quickly to ever be found in fossils older than a million years. Then in the mid-1990s surprise! Soft tissue and proteins were found in dinosaur fossils. Not only this, but now it seems that they are found whenever we actually look for them. Rather than arriving at the obvious conclusion (such fossils must be younger than a million years old) the old Earth community simply said, “Well I guess DNA can last for 65 million years.” They can always come up with an ad hoc means of saving their paradigm.
But is that the obvious conclusion? Would it really be rational to discard all the other data which has been repeatedly and independently verified? Is it more likely that everything science has learned about the relevant the disciplines, or that current scientific knowledge of cellular degradation is incomplete? If dinosaur fossils were less than 10,000 years old than obtaining tissue samples would be relatively common rather than a revolutionary discovery.

There were other people who swore that the boat stayed intact all the way down (we know the ship broke we just do not know when). Now this is a huge discrepancy seen in people who experienced the event themselves. Now compare this with people 20 generations out from an event and you’d expect great differences in the stories. There are some very significant similarities in the flood accounts though. One of the Australian accounts is very similar to the Genesis account (Gajara was told to build a vessel for himself, his wife, his sons and their wives. The flood covered the highest mountain tops. He released birds to see when land was available. They made an offering to God after the flood. God placed a rainbow in the sky to prevent future flooding.); yet aborigines are supposed to have been isolated as a people group for a very long period of time.
I agree that stories get distorted over time. The example flood myth you gave is interesting, mainly because I can't seem to find any reference to it other than creationist websites.

Well in science it is important to always value what we know through empirical means over what we infer occurred in the past. We know that the rates of cellular and biotic degeneration are far too great to ever last for 65 million years. So if we find such material in fossils that we inferred were 65 million years old we need to have the intellectual honesty to admit that we were wrong. They actually do find it now all the time, they had just never really looked very closely because they knew they’d not find any. It was interesting; at the time many scientists vehemently argued that what they were finding was not soft tissue and proteins because they knew the implications of this. Now since the evidence is overwhelming they merely argue that soft tissue and proteins can last that long. Think about that though, they believe that DNA sequences can survive intact for 65 million years…even though it’s hard to retrieve a significant amount of DNA from remains that they know are a few thousand years old. This would be like a person claiming that they were 1.9 million years old and everyone believing them even though the empirical data suggest people cannot live much past 100 today.

Why did she receive so much resistance from her colleagues? As a side note, the soft tissue does not tell us how old the Earth is, but it certainly does give us a strong suggestion of how old those dinosaur fossils are.

So, if the speed of light is different in different directions, then the clocks will experience different time dilations, even if they are moved at the same speed.
Also, a signal sent from the central position will travel at different speeds in the two directions if the speed of light is different in different directions. So, the clocks will not necessarily be synchronized when a signal is sent from the original central position.

I'll assume you're talking about Galilean principle of relativity whereby the velocities transform by pure addition. This concept breaks down when the speeds one is dealing with are very large.

The point is that velocity of light corresponds to zero Minkowski length and so light moves at a constant velocity in every inertial frame. This is the famous Einstein's postulate, which has been shown time and time again to be true.

There are several problems with Lisle's explanation. first, NASA and many others have conducted experiments in time dilation and have found in all instances that the clocks were off be equal but opposite amounts, indicating that the velocity of light is, indeed, isotropic. Secondly, he conveniently ignore the fact that no frequency shift has ever been detected in any measurement of the speed of light. And finally:
his explanation for how distant starlight is compatible with a 6 day creation only a few thousand years ago is very, very weak. It essentially consists of immediately throwing out the conventional science just because it conflicts with scripture and then proposing that "creation was supernatural, therefore cannot be understood scientifically".[7] Most of Lisle's points just begin with the claim that the Bible must be true, cannot change and so can explain everything[8] and he's no stranger to wall-bangingly circular logic.[9] It shouldn't need to be stated that this is the opposite of what a good scientist should do. So, while he may be a published and qualified scientist, the remarks he makes regarding creationism aren't actually very scientific - indeed, for AiG to use him as a leading scientist is practically a sham, as it leads their audiences to think that his ideas - which aren't really his ideas, just the same old tired arguments - automatically have credibility due to his real PhD. Although he has done research with genuine merit into the sun's heliosphere, Lisle has yet to perform, let alone publish, credible work into starlight or creationism.

This is fallacious yet again. You’re invoking a circular argument; it’s a scientific fact that Earth is billions of years old because the majority of scientists believe that is the case and the majority of scientists believe that is the case because it’s a scientific fact. It was not a scientific fact that the Universe was eternal in the 1920s when the consensus supported Steady State Theory. The consensus is often wrong in science, therefore merely appealing to it is fallacious.
Quote: I'll assume you're talking about Galilean principle of relativity whereby the velocities transform by pure addition.
No, I am talking about the definitions of the terms velocity and speed. The two-way speed of light in a vacuum is constant, the velocity is not a constant. This is why people stop replying to you, you do not actually listen to what is being posted.
Quote: To talk about the differences between speed and velocity, let's talk about how they are defined.
Speed can be defined as the distance traveled divided by the total time taken. So, speed = distance/time.
While velocity can be defined as the displacement divided by the total time taken. So, velocity = displacement/time.
Now, let's imagine a person who ran around a circular park and returned to the same spot that he started from. The person would have covered a certain amount of distance around the circular park in a certain amount of time. If the person ran really fast, he would have used up less time to run around the park, and thus he would have a high speed. But if he ran really slowly, he would have used up more time to run around the park, and thus he would have a low speed. This part seems rather intuitive for now.
But, let's move on to velocity. Because the person ran back to his starting position, he would have zero displacement. Displacement is the difference in distance between the starting and final position. So, since displacement is zero in this case, we can say that the running man has an average velocity of zero!
So speed depends on distance traveled, while velocity depends on the displacement.
I'd also like to point out that speed is just a number (e.g. 10m/s or 24km/hr). However, when we talk about velocity, we usually have to describe the direction as well (e.g. 10m/s northwards or 24km/hr eastwards). It's because the velocity changes when the direction changes that the velocity can average to zero even though it isn't zero at any particular time.
Quote: The point is that velocity of light corresponds to zero Minkowski length and so light moves at a constant velocity in every inertial frame. This is the famous Einstein's postulate, which has been shown time and time again to be true.

his explanation for how distant starlight is compatible with a 6 day creation only a few thousand years ago is very, very weak.
Opinion.
Quote: It essentially consists of immediately throwing out the conventional science just because it conflicts with scripture and then proposing that "creation was supernatural, therefore cannot be understood scientifically".[7] Most of Lisle's points just begin with the claim that the Bible must be true, cannot change and so can explain everything[8] and he's no stranger to wall-bangingly circular logic.[9] It shouldn't need to be stated that this is the opposite of what a good scientist should do. So, while he may be a published and qualified scientist, the remarks he makes regarding creationism aren't actually very scientific - indeed, for AiG to use him as a leading scientist is practically a sham, as it leads their audiences to think that his ideas - which aren't really his ideas, just the same old tired arguments - automatically have credibility due to his real PhD. Although he has done research with genuine merit into the sun's heliosphere, Lisle has yet to perform, let alone publish, credible work into starlight or creationism.
The link did not work so I cannot figure out who you are quoting here. However, the fact that it is all merely some poster’s opinion means it does not prove anything anyways.
