Please note that we do not recommend LLMs as sources. Do you mean the specific topic of quantum tunneling, or QM in general? I would...

Where? Please give a reference.

No. Planck's constant is a constant. It doesn't change no matter what happens to any quantum system.

Where? Please give a reference.

Sorry, but that's not what PF is for. We are here to help people understand mainstream science. That includes mainstream QM, but, as has...

I think so. I'm wondering whether the paper talks about this explicitly.

This doesn't look like they're differentiating with respect to ##\tau##, but with respect to coordinate time ##x^0##, at least on the...

The paper is behind a paywall so I can't read it. Is there an arxiv link to a preprint? Or, if you can post a relevant equation here...

Yes, that's a good reference. Note that in that discussion, the known functions of ##\tau## are the coordinates ##x^\mu##...

Wrong. If you can only take a partial derivative with respect to ##\tau##, then you do not know everything as a function of ##\tau##...

Why? You said we know everything as known functions of ##\tau## only. Differentiating a known function of ##\tau## with respect to...

Then this thread is personal theory, and will remain closed.

Um, just differentiate the known functions of ##\tau## with respect to ##\tau##?

We don't know. Different interpretations of QM say different things about this.

This question has already been answered: cosmologists so far have paid little or no attention to the theory. Ultimately it's up to the...
