JThe point is that the ratio of scale factors is also the ratio of CMB temperatures. At recombination the temperature was about 3000K by...

In "Supernovae evidence for foundational change to cosmological models" they say Physically, it is motivated by an extension of... -
Jjavisot replied to the thread Undergrad Questioning the timescape model.Like timmdeeg, I would like to know if it is a coincidence that the anomalous acceleration of the expansion of the universe can be...

Jjavisot reacted to iste's post in the thread Undergrad Valid local explanation of Bell violations? (Pegg et al., 1999; 2008) with Like.
Its not the quantum state at preparation but they are still evolving a quantum state backward in time from measurement. They are doing...

Jjavisot reacted to .Scott's post in the thread Undergrad Valid local explanation of Bell violations? (Pegg et al., 1999; 2008) with Like.
The Sutherland paper cited in the OP claims that locality can be preserved when a retro-causal mechanism is employed. In most cases...

Jjavisot reacted to Borek's post in the thread Why have the number of questions declined over recent years? with Like.
Several processes - one is that at some point "all questions were already answered", quite often it was enough to google for problem to...

Jjavisot reacted to martinbn's post in the thread Undergrad One does not “prove” the basic principles of Quantum Mechanics with Like.
It doesn't seem to me like that at all. But it may be that I don't understand it, and I am projecting my own philisophical prejudices...
