Here is my comment policy, and technical help if you want to include equations in your comments:

1) You are welcome to leave comments on old posts—pretend they were all written yesterday!

If you attempt to leave a comment and for some reason it does not appear, perhaps it has gotten stuck in the spam filter.  Please send me an email letting me know and I will rectify the situation.

2) Please make some attempt to put your comment on a topically suitable top-level article, e.g. the one which you are responding to.  (If you can't find a good place, go ahead and put it somewhere random—I don't mind the occasional off-topic comment, but it's awkward if it could have been on-topic had you put it in the correct place.)

3) You can include LaTeX formulae in your comments by putting double dollar signs on either side.  For example, ${\mathrm \\\verb|\|frac\{e\verb|^|\{-X\verb|^|2 / 2\}\}\{\verb|\|sqrt\{2\verb|\|pi\}\} \\ }$ becomes $\frac{e^{-X^2 / 2}}{\sqrt{2\pi}}$.  If you want to break it out into its own line, just place an "!" immediately after the first pair of dollar signs.  (Don't try to use the wordpress.com format, since that doesn't work on wordpress.org blogs)

4) Don't use the symbols < or > in your comment (unless you use just one), as WordPress may intepret them as an html tag and mutilate your comment!  You can make these symbols by inserting \lt or \gt inside of the double dollar signs, for < or > respectively.  Alternatively you can use the html escape codes $\&$lt; or $\&$gt; even outside of the double dollar signs.

5) At this time there is no way to edit your own comments to fix typos or incorrect equations.  However, if you write a second comment pointing out the mistake, I may fix your original comment and delete the correction, so that it looks like you got it right from the beginning.

6) This is a Christian website, which exists for the purpose of glorifying God.  Commenters with other beliefs are welcome to comment on the site for purposes of friendly discussion, but I ask that you refrain from gratuitious blasphemy (i.e. derogatory insults and jokes directed at God which aren't necessary in order to respectfully state your position).

However, nobody but me is obliged to follow my eccentric canonization policy of referring to all Christians as "saints".

7) I also ask that you be civil to the other commenters.

8) Commenters should provide a valid email address in the comment form, so that I can write to you privately if there is an administrative issue that shouldn't be shared with everyone.  These email addresses are not visible to the public, nor will they be released to other organizations.

The "website" field is public, but completely optional—feel free to leave it blank or to insert a link to your own website.

9) Do not simply copy and paste a large amount of text from your own pre-existing blog post into the comments section.  I will be able to tell it was not original by doing a google search.  Comments should be an individualized response to what I, or the other commenters, have said.  This does not mean that quoting relevant materials you've written before is forbidden, but it should be in the form of a link or a short quotation, and you should include an explanation of what it is, and why you are introducing it into the discussion.

10) If you figure out any other way to abuse the process, I may have to invent some ex post facto rules in a hurry.  But I would rather have a community of people who use common sense when deciding what kinds of comments are suitable.

Hey. I'm a Christian and I'm very interested in apologetics. When I saw the Craig-Carroll debate, I was very concerned because Alan Guth, one of the authors of the BGV theorem, said that the universe is "very likely eternal". This would be a serious problem for the second premise of the kalam cosmological argument. It caught me off guard since Alexander Vilenkin, another author of the BGV theorem, said that Craig properly represented the implications of the theorem (that the universe had a beginning) http://www.reasonablefaith.org/honesty-transparency-full-disclosure-and-bgv-theorem. Is the BGV theorem a reliable way of showing the universe had a beginning? Please help

2. Aron Wall says:

David S,
Are you putting your trust in theorems about Nature, or the one who made Nature? If the latter, I don't see why you should be "very concerned" if the BGV theorem turns out to say less than you hoped. Of course, when we construct arguments for the Christian faith it is easy to become emotionally invested in the premises we are drawing upon, but remember that most of the saints through history found a way to believe in Christ without the aid of the BGV theorem! Apparently there are other ways of coming to know God.

The BGV theorem very roughly tells us that inflation can't have gone on forever to the past, but it does not automatically imply that there was an absolute Beginning, as I discuss here. This was part of a longer series about the question of whether there was a beginning, according to the our current scientific knowledge.

The fact that Vilenkin and Guth have different views from each other is a normal difference in scientific opinion, coming from the fact that our best current theories of Nature break down in the very early universe. Personally I think Vilenkin's view is better supported by the evidence, but I can't say it's been scientifically proven.

Hey Aron,

I tried finding your email to send a personal gratitude for the work that you have done on this blog but I wasn't able to. So I'm just going to comment it here.

Your blog is a blessing to me. I feel that your honesty and transparency on scientific as well as theological issues really give a clear and concise explanation. And it is also a blessing to see that there are Christian who pursue the sciences and invest time to put it in layman terms for us to understand.

Because of your blog, I now have one more venue where my faith can be strengthen. I can be assured that faith does not depends solely on personal, subjective encounter with God (and I'm not denying that this isn't an important aspect, I think it is a crucial aspect), but that there are evident that affirm these subjective experiences.

And your blog really opens my eyes to what ministry really is. You are one of the few people that really make an impact for Christ even though you are not in a professional ministry position. That's really encouraging because your life really shows that whatever profession you find yourself in, God can use you greatly if you would allow Him to.

Anyways, I just want to say a big thank you. Your work is greatly value (more so than I'll ever know in this life time). Much appreciation and gratitude from me and from deep down, God bless you!

Thanks for the kind words, Duc. While I have no objection to being praised in public (vain fellow that I am) if you ever need to send me a private email the address is on my webpage, which can be found by clicking on the "webpage" tab at the bar on the top.

Dear Aron,

I hope and pray you are doing fine.

I will try to keep my comments short (perhaps more will come later, for what they are worth).

In 2 Chronicles 4:5 of the KJV (King James Version), one will see "received and held three thousand baths."

Can you comment on it - such as if you find anything significant in it?

Thank you.

Hello Dr. Wall,
Thanks,
Chris

7. Aron Wall says:

Chris,
I think most of what I have to say about this subject can be found in these two posts.

I don't think that Aspect's experiments on entangled particles imply simultaneous causation at all! At least, the result you get is the same regardless of which order you measure the two particles in. So it seems arbitrary to say that one is the cause and the other is the effect. It is true that the Bell Inequality tells us that the two measurements are correlated in ways that no classical pair of systems could be, absent causation. But that just means that classical mechanics is wrong, and you need quantum mechanics to describe the way in which the two particles are related.
