Need Help with Writing?

My wife has spent nearly a decade teaching people how to become better at writing.

If you are 16 years or older, and you need help learning how to write a good academic essay — no, she won't write it for you, that's plagiarism! — then please check out St. Nicole's online tutoring service.

She has a lot of experience with ESL students.  She also offers copyediting, if that's what you need.

She's got two masters degrees, and lots of teaching experience.

What is the connection between this and my usual science and religion fare?  Well that's simple.  THIS content (on my blog, anyway) is always going to be free.  But if you'd like to support us, you can always go over there and pay for THAT content.

About Aron Wall

I am a Lecturer in Theoretical Physics at the University of Cambridge. Before that, I read Great Books at St. John's College (Santa Fe), got my physics Ph.D. from U Maryland, and did my postdocs at UC Santa Barbara, the Institute for Advanced Study in Princeton, and Stanford. The views expressed on this blog are my own, and should not be attributed to any of these fine institutions.

    Hello Aron! Thank you for this!

    If you don't mind me asking a quick question (alas, about physics): you have previously talked about the Quantum Eternality theorem. Sean Carroll has said that if the total energy of the universe is 0, then time turns out to be not fundamental, in a very funny way.

    What does it mean to say that time is not fundamental? Is it not fundamental in the sense that B-Theory of time is true, and there is no objective "passage of time," and we are instead in a "block universe"? Or in the sense that the holographic principle is true?

    If this is true, do we have to throw all out conceptions of time out of the window? Are we forced to conclude there is no time at all? That there is really no objective way in which things are said to happen before other things? In B-Theory, we would usually say that some moments are indexed earlier than others in the eternalistic block universe. Would that also turn out to be wrong?

    Thank you!

    Hello, Aron, If you don´t mind, i too have a question:
    Can the Cosmic microwave background serve as a preferred frame of reference in the context of relativity?
    Because it´s astonishingly isotropic and it is at rest with the expansion of the universe. Can it be the "cosmic time''that philosophers of time talk about?

  3. Luan says:

    Hello Arron. I am a theist, and I have doubts about the creation of God, how God created space-time if there was no time before. the question before is meaningless without time

  4. Aron Wall says:

    flavio,
    It's isotropic to a high degree of accuracy, but it isn't exactly isotropic, and therefore it can't serve as a metaphysical basis for an absolute frame of reference.

    The photons in the CMB don't penetrate to the center of the Earth, but that doesn't mean that there is no time there! (Although, if Einstein was right, there is no absolute Newtonian time anywhere.)

    Hi Aron,

    I have a question I would really like for you to address. I have read several of your blogs and really respect your opinion. What is your stance on gay Christians? Should we affirm the LGBT community or not? It would mean so much to hear from you on this subject, as it has been something many Christians struggle with.

    In Genesis when Lemech says that Cain is avenged sevenfold but he will be avenged seventyseven fold.
    It sort of struck me that to make this kind of remark the author needed to have some idea of decimal base-10 arithmetic.
    Even in the Gospels, when Jesus goes from seven to seventy times seven, isn't there a hint of decimal system?
    Is it possible to link 7, 70 and 77 in arbitrary base arithmetic?

  7. JamesH says:

    In Genesis seven symbolised completeness and perfection. God's creation was complete and perfect and was completed in seven days. There are many similar references in, particularly, OT.

    Jesus’ reference to seventy times seven is to be understood as an injunction to forgive a limitless number of times and is, perhaps, related to the consideration above. So I don’t think the reference has anything much to do with a decimal system.

  8. Mactoul says:

    I was perhaps unclear. It is claimed that the decimal system comes from the Hindus and appeared in the West only in post Arabic era.
    So I wondered regarding the poetry of Lemech utterance that links 7 and 77.
    This linkage is obvious to us thanks to the decimal numbering but presumably the Hebrews didn't have decimal numbers.

    Merry Christmas, Aron!

    hello aron, what's your opinion on this article? https://www.sciencedirect.com/science/article/pii/S0370269314009381

    do you think it defines a universe with no beginning?

  11. Aron Wall says:

    Luan
    I don't personally know anyone in physics who takes the Ali and Das paper seriously as a plausible research direction, and it doesn't seem to me like the right way to introduce quantum effects into cosmology. In any case it seems highly speculative and not based on physics ideas whose validity has been clearly established. That's all I have to say as I have not studied these papers closely.
