How do you have an external observer to the universe?

Here's a quote from the article...

"Then, in 2055, Laura Yee, a freelance engineer and part-time dream designer, posted a short article in which she postulated such an equality at all distances and energy scales."

2055? Dream designer? Smells like fiction to me.

I noted another one of these...Apparently 2066 was a "game changing" year. Since the Physics sounds fairly legit, though speculative, I'm guessing the typesetter doesn't proofread enough.

Still, I am skeptical on two points here. 1) If I am understanding things correctly the web structures would appear at a significant fraction of the TOE unification energy. I'm not saying we couldn't detect it now but there is just as little reason to say that we can. 1 TeV sounds waaay too low. 2) Again, if I am understanding things, if space-time is cell-like at its most primitive level then a space-time event is a single cell. According to the Universe on that scale a cell is a point. This solves the point singularity problems as nicely as String Theory does but it will still be a long time before we can do an experiment to test it.

I hasten to say that these are my opinions. Until I can get a look at the actual papers I can only speculate. Though I would dearly love to, I don't have the finances available to get anything but journal abstracts.

So, little theoretical basis given and no experimental proof....As unpalatable as it is I'm going to have to stick with the point particle idea. Later developments will say how to deal with the troubles involved with that.

Indeed. Google (or Physics Today) hasn't heard of any Laura Yee than might this this one, nor Abel Kateb, nor an African Arrow particle accelerator in Morocco.

The first section talks about Kateb latter riding a hyperloop to the Moroccan particle accelerator. There is only one physical hyperloop and it's being built in the US.

It's written by an academic, who works for HP, but I suspect that it's a vision of the future course of scientific study rather than anything more substantial.

I agree. How could this get in Physics Today as established fact?

Nothing is established fact until we have experiments to back it up. Until then theories are necessary and nice but we can't ignore the Scientific Method. Lots of people (I'm talking to you, String theorists!) forget that from time to time.

Physics Today invited speculative (i.e. fictional) essays about physics in the future. This thread relates to one of those essays, written by Pavel Kornilovich.
