Jjavisot reacted to PAllen's post in the thread High School Estimates — True Size of the Universe? with
Like.
I’ve used the following analogy to picture an infinite expanding universe. Consider the universe as an (countably) infinite collection... -
Jjavisot reacted to Jaime Rudas's post in the thread High School Estimates — True Size of the Universe? with Like.
Yes, because expansion, in this context, doesn't mean its size increases, but rather that the distance between objects gets ever...

Jjavisot reacted to Ibix's post in the thread High School Estimates — True Size of the Universe? with Like.
Imagine a line of stakes 1m apart. The line is so long you can't see the end - and maybe there is no end. Go away and come back, and...

Jjavisot reacted to BillTre's post in the thread What causes the asymmetry in a symmetrically developing organism? with Like.
There are different kinds of asymmetry found in animals. The kind you are talking about are kind of subtle deviations from perfect...

JThat's correct. What you are calling "ordinary" QM is a non-relativistic approximation. For relativistically correct QM, you need...

Jjavisot replied to the thread Undergrad Questioning the timescape model.You're right, I didn't share the papers with the intention of correcting anything. If you look at all four papers, they all state...

Jjavisot reacted to PeterDonis's post in the thread Undergrad Questioning the timescape model with Like.
The fact that these papers claim to be testing "the equivalence principle on cosmological scales" doesn't mean the concept actually...

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

Jjavisot reacted to timmdeeg's post in the thread Undergrad Questioning the timescape model with Like.
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...
