Re: Ethan Siegel the star gazer says that despite dark matter the universe ain't expanding faster

Ok Jesse, nothing has changed, and the Standard Model seems solid. Shame on 
Siegel for getting people worked up for the price of selling an article. 
"Nonstandard terminology" seems a method for lying via exaggeration. Thanks for 
the info.
Spud.

Subject: Re: Ethan Siegel the star gazer says that despite dark matter the 
universe ain't expanding faster

Ethan Siegel just seems to be using non-standard terminology here to express 
the same results that have been known for a long time--he says that what he 
means is that "the expansion rate — also known as the Hubble constant/parameter 
— still decreases" even though "each individual object that’s receding from us 
will recede at faster and faster speeds as time goes on". If you look at 
https://en.wikipedia.org/wiki/Accelerating_expansion_of_the_universe#Technical_definition
 they say that cosmologist typically define "accelerating expansion" to mean 
the second derivative of the scale factor a(t) is positive, meaning the scale 
factor is increasing with time, and 
https://en.wikipedia.org/wiki/Hubble%27s_law#Time-dependence_of_Hubble_parameter
 notes that it's quite possible for the scale factor a(t) to increase with time 
while the Hubble parameter H(t) is decreasing, and in fact that's what 
observations suggest is happening (as Siegel points out). The article even 
notes that one implication of this is that "The recession velocity of one 
chosen galaxy does increase, but different galaxies passing a sphere of fixed 
radius cross the sphere more slowly at later times".
