Do you agree that in Big Bang cosmology, our universe's time and space begin at the start of the Big Bang? If you do, there's nothing for us to discuss here.What is the difference?

Time appears to by some interpretations. The visible universe also appears to have been a singularity at that time, or at least some singularity analog. Whether that singularity was all there was is unknown. I don't know of any particular reason to assume it was.Do you agree that in Big Bang cosmology, our universe's time and space begin at the start of the Big Bang?

Since you ignored my question, I'll ignore yours.Do you agree that a cloud starts with condensation?
Again, I'm no cosmologist, but in the Big Bang cosmology space itself appeared, and is still growing. Which is weird, and wasn't how I imagined a "big bang". I imagined it as an explosion into existing space, which is how most people do. But it's not that at all.[serious];65400953 said:Time appears to by some interpretations.

Cells with DNA are modern cells that are the result of biological evolution, yes. But Abiogenesis is not a process that ends with DNA based cellular life. DNA based cellular life evolved from simpler forms of life.
I'ld say, the moment an organic self-replicating molecule exists that is subject to darwinian processes and mechanisms.
I'm not sure about that do you have a link. I know they try to explain it but I dont think they have proved it. Experiments with the fruit flies hasn't produced any different and new features like giving the fly a tail or grass hopper antennas. It has only changed the existing features and in fact over time most of the flies have become less healthy and functional. They have only created poorer versions on the whole but with the same features.This is not really true though. How such things can and do happen is well understood and well explained in biology.
Yes but if you truly go into what is involved in a creature taking on a new feature it hasnt got its not so simple as people make out. They just imagine a lung growing or wings growing. But there are all the blood vessels, nerves, capillaries, tissue, ligaments, connections to the brain ect. One cant function without the other. Yet darwins evolution says that this can happen in small incremental steps. So its hard to imagine a part of something growing. Or the genetics for say the heart muscle coming without the nerve connections or brain signals coming at the same time.As they exist today. It's not only the parts themselves that evolve, it's also their function within the whole.
But thats like saying there was a fluke that the insect and the flower came at the same time by random chance. It was so perfectly timed so that each could survive. This is the same for body parts and systems that depend on each other. Sometimes it may be many more than 2 occurrence that need to happen at the same time but many. Then it begins to get a little unbelievable that they could all form at the same time. That a random and blind process could do that.Just like convergent evolution between species... There are plenty of plants that depend on a specific type of insect for reproduction for example. Likewise, these insects depend on those flowers for food.
Take away the plant and the insect dies.
Take away the insect and the plant can't reproduce.
This is not really true either.
Take the human eye for example. If an engineer at Sony would design a camera that roughly works in the same manner, he would be fired instantly for such amateurish and chaotic design.
All the wiring (the nerves) is actually found in front of the light-sensitive cells. These wires come together at the back of the eye and go to the brain through the back. This place is called the "blind spot". Our brain has to put in extra effort to "fill in the blanks" to correct for this. This is the kind of tinkering we expect from a blind process like evolution. It's not what we expect from some super-intelligent engineer.
Well it could be thats the way it needs to be for us humans. Our eyes are very unique and despite the comparison to a squid we can see and use our eyes a lot better. It could also have to do with our brains as we also have a greater depths of perception. Who knows why it is this way and it doesn't necessarily mean its badly wired. We still have yet to discover things. But at the end of the day our eyes work perfectly well just how they should be for us. But they are still highly complex and amazing and I just cant see how they could evolve from nothing more or less. Even a simple eye has to come from somewhere and the genetics were not there in the first place to make them. Nor could random mutations create the info to do it as it would need new info. Mutations are normally a mistake in the copying process not a beneficial thing that cant create complex functioning features. Eyes are not a mutational error.The squid for example, doesn't have this problem.
I can understand that a variation in the genetics from existing genetics in a group could be taken on as the ability is already there. In fact i believe that its almost pre designed that way. There is enough room for adaptation withing existing genetics to mold a group around a fair amount of environmental situations. Maybe even certain changes in their genetics is favored in certain circumstances. But random mutations giving positive productive changes that grow functional new features is that are not withing the genetics of that gene pool is hard to believe. Considering that they are most neutral or deleterious it would take a lot of positive mutations which I m not sure are even available to make something that is not an error and would be rejected.Natural Selection is not a random process.
Evolution as a process holds random ingredients, yes (mutation being one of them). But selection is far from random.
Thats what I find hard to believe. That this process could have made everything on earth. Basically a error in the copying process created the most complex and amazing animal kingdom from an organism that had none of the features we see today. Even from the point of chemicals to that organism that was floating in the primaeval soup was an amazingly complex process and the same principles apply. Creating something that looks like its designed from a random and blind process from more or less nothing being there in the first place. We think we are clever when we make something so complex yet here we have something far more coded for life and looking some well put together coming from a fluke. Its like nature is masquerading as God.Blind, yes. In the sense that there is no end-goal in mind for any specific design. As in: homo sapiens was not "meant" to exist. It just turned out this way. It could have just as well be completely different. Had that asteroid not hit us 65 million years ago, chances are big that dino's would still dominate.
Since you ignored my question, I'll ignore yours.
...enormous wall of text....
So how did the simple life evolve into more complex multi celled life that has DNA and can reproduce with say an embryo. There would be thousands of unique and complex things that had to happen and much of it would have depended on 2 or even many parts being present at the same time and all interlocking and fitting together like a jig saw puzzle. This had to happen with that prior info being there to create it. So a random and blind process is suppose to build these highly complex prototypes of life. How could some of these things happen all at once and fit all together by a fluke of nature. [/quote
You need to show that they would need to happen all at once, something you haven't done.
New info can be introduced into a gene pool from outside such as with HGT. But I cant see how it can be introduced within when its not there in the first place.
Do you think reality is limited to your limited knowledge?
No amount of mixing and recoding is going to make the type of genetics that are needed for more complete tasks and features if they are not there in the first place.
Evidence?
I'm not sure about that do you have a link. I know they try to explain it but I dont think they have proved it.

It has only changed the existing features and in fact over time most of the flies have become less healthy and functional. They have only created poorer versions on the whole but with the same features.
So we haven't seen millions of years worth of evolution in the span of fifty years. Why is that a problem?
Yes but if you truly go into what is involved in a creature taking on a new feature it hasnt got its not so simple as people make out. They just imagine a lung growing or wings growing.

I can show you animals with tissue and nerves, but no brains. Jellyfish don't have brains, but they do have nerves.
I can show you animals with tissues but no capillaries, no nerves, and no ligaments. Sponges have tissues, but none of the rest.
Contrary to you claims, they don't have to be there all at once.
But thats like saying there was a fluke that the insect and the flower came at the same time by random chance. It was so perfectly timed so that each could survive.
Insects show up early in the fossil record, well before flowering plants do.
This is the same for body parts and systems that depend on each other. Sometimes it may be many more than 2 occurrence that need to happen at the same time but many. Then it begins to get a little unbelievable that they could all form at the same time. That a random and blind process could do that.
Given everything else you have been wrong about, why should we take your word on it?
It's not that simple. That's kind of a first approximation at understanding.Again, I'm no cosmologist, but in the Big Bang cosmology space itself appeared, and is still growing. Which is weird, and wasn't how I imagined a "big bang". I imagined it as an explosion into existing space, which is how most people do. But it's not that at all.
The "balloon and dots" analogy is how I was taught. Here it is, if you haven't yet run across it:
Where is the centre of the universe?
In order for us to see we need more than just eyes, We also need the optic nerve, digital code and the visual cortex. This is something beyond the ability of our engineers. Also our cameras are not 100% recyclable unlike our eyes.Well it could be thats the way it needs to be for us humans. Our eyes are very unique and despite the comparison to a squid we can see and use our eyes a lot better. It could also have to do with our brains as we also have a greater depths of perception. Who knows why it is this way and it doesn't necessarily mean its badly wired. We still have yet to discover things.

Even a simple eye has to come from somewhere and the genetics were not there in the first place to make them. Nor could random mutations create the info to do it as it would need new info. Mutations are normally a mistake in the copying process not a beneficial thing that cant create complex functioning features. Eyes are not a mutational error.
I hear you and I'm fine with that. I'm just hoping you understand that you're beyond Big Bang cosmology when you explore those paths.[serious];65401489 said:It's not that simple. That's kind of a first approximation at understanding.
Let's take that balloon analogy. Sure, we can see that as the balloon inflates, points get further away from each other. Now, our little ant crawling over the surface sees that and says, "wow, my balloon universe must have been a single point at some point in the distant past!" And he's right. But does the part of the balloon that is causally related to him represent the whole balloon? What if the balloon was infinitely large? He would still see the stretching as it inflated and all those points he sees would trace back to the same point as he calculated back, but the balloon would still have infinite points beyond his detection.
We see stars and can trace those stars back to a start. But the scope of that underlying balloon is unknown.
It didn't. If you've got time for this kind of round-and-round you'll have to find someone else.It answers your question.
Do you agree that clouds start with condensation?

This is something beyond the ability of our engineers.
We now understand Muller cells act like fiber optic cable which deals with bad design argument.
Also the back of the retina needs a large blood flow so there are good reasons camera eyes are wired that way.
It didn't. If you've got time for this kind of round-and-round you'll have to find someone else.
Functional camera eyes? Even a blind man can detect light.Is that true for all life? Nope.
Box jellyfish have eyes, but no optic nerve and no visual cortex to speak of.
One of a box jellyfish’s multiple sets of eyes allows it to see the world above the water so it can navigate, a study indicates. | LiveScience
Basal chordates like the lancet don't have anything close to our visual cortex, yet they have functioning eyes.
Again we are talking about camera eyes not just detecting patterns and light.Non-sequitur.
Having light shine through nerve cells before hitting our photoreceptors is a big reduction in both light collection and resolution. There is no rescuing that. Also, the cephalopod eye has none of these problems since the nerves exit out the back of the retina.
No, there isn't. You can get sufficient blood flow without passing nerves in front of the retina. Cephalopods already do it.
So how did the simple life evolve into more complex multi celled life that has DNA and can reproduce with say an embryo. There would be thousands of unique and complex things that had to happen
and much of it would have depended on 2 or even many parts being present at the same time and all interlocking and fitting together like a jig saw puzzle.
The odds are highly stacked against it happening
Mutations are mostly deletions and rarely beneficial.
Gene are copied from what is already existing. Any variations are from what is already there.
It may change things that are existing like color or size or give hair and lack of something but it cannot create new info that will make something completely new that require new genetic info that wasn't there in the first place.
I'm not sure about that do you have a link. I know they try to explain it but I dont think they have proved it. Experiments with the fruit flies hasn't produced any different and new features like giving the fly a tail or grass hopper antennas.

Yes, stevev please Google "evolution of the eye" and see if there are any mention of the optical nerve, complex digital code and the visual cortex. It's just the eyeball without mention how did the eyeball know if it develop into a camera eye it would result in our brain building visual images. Remember the sun doesn't give off light as we know it but electromagnetic waves. Our brain ability to create images at great speeds is a very complex process that even our best supercomputers can't do. Our eyes detects electromagnetic waves but it's our brain which create the images we see.Google "evolution of the eye".
Functional camera eyes?
