Good point. And the values of ##t## might depend on where one lives, in a wall or in a void.

Yes, but isn't it astonishing that otherwise much different models predict this very same ratio of scale factors? Of course they have...

What I meant, saying "coincidence" : There are two models (one established and the other one speculative) which explain the measured...

In "Supernovae evidence for foundational change to cosmological models" they say Physically, it is motivated by an extension of...

No. The expansion factor of 1100 is based on data, not models--all models have to account for it somehow. Yes, that's how the different...

Thanks, got it.

"Supernovae evidence for foundational change to cosmological models" https://arxiv.org/pdf/2412.15143 The paper claims: We compare the...

Last night was the first clear night in a while- I had a chance to image Jupiter @ 800mm: From the top, a stacked image of 40 subs...

In RQM, what matters is the transition probability between two events involving the particle. If there is a gravitational field, it is...

Thanks for clarifying, this I've been missing even though I'm watching chess games online sometimes.

Here is a quote from Rovelli. Taken from here https://plato.stanford.edu/entries/qm-relational/ To me this is clear. The existence of...

Imagine that we were living in a simulation. Everything would look the same, but there would be no force of gravity, as such. A...

I'm still not clear with this. Wouldn't the assumption that "a particle may not exist beyond measurements/observations/interactions" be...

In fact, Rovelli developed the relational interpretation inspired by his work in loop quantum gravity. He discusses this in section 4(c)...

Note that the Rovelli paper above does not consider the question of the existence of an electron, as we have been discussing it here...
