Re: Hubble's Constant

2022-12-02 Thread Jesse Mazer
The wiki page on the Hubble parameter also says in the section at
https://en.wikipedia.org/wiki/Hubble%27s_law#Time-dependence_of_Hubble_parameter
that the expansion seems to be accelerating in such a way that the first
derivative of the scale factor a(t) is increasing over time but the Hubble
parameter H(t) is decreasing, and that this has the implication "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". There's a more technical discussion of how these parameters
are defined at
https://en.wikipedia.org/wiki/Accelerating_expansion_of_the_universe#Technical_definition
which mentions that physicists define "accelerating expansion" specifically
in terms of the second derivative of the scale factor being positive, it
doesn't require an increasing Hubble parameter.

The FLRW expansion factor is exp(Hd/c), where Taylor's theorem means 
exp(Hd/c) = 1 + Hd/c + 1/2(Hd/c)^2 + ... . For small distance d we have 
exp(Hd/c) =~ 1 + Hd/c, and for Hd = v this is exp(Hd/c) =~ 1 + v/c. To 
convert this to a time dependent expansion then d = ct.

Re: NYTimes.com: How China Lost the Covid War

2022-12-02 Thread spudboy100 via Everything List
My bet is that the Chinese bribe-wagon will come to a close, because of Xi and 
the CCP's need to maintain power, divert internal rebellion and blockade 
Taiwan, which is less of a threat to the PLA than a true invasion. Apple's 
board of directors will likely in the event of US casualties (a possibility?) 
be blamed by the public.
Don't worry, DeSantis will fix it!

That would be impossible because Xi Jinping has said repeatedly that the 
Chinese vaccine made with old fashion techniques was just as good or better 
than the newer method using CRISPR gene splicing technology; to change policy 
now, after a brutal lockdown and hundreds of thousands of Chinese deaths, would 
be admitting he made a grave mistake. And dictators NEVER make mistakes.

You just figured that out? I've always known that capitalism was better than 
communism, not perfect but much better.

Your hatred of Apple is not a sufficient reason for me to boycott them because 
you only know how to play one tune on your sad little violin and "Outrage In 
The Key of Hate" starts to get a bit old after about 11,000 repetitions. You 
hate communists but you hate capitalists even more, in fact you've admitted 
that you hate everybody, except of course for the potential dictatorship of 
Donald Trump, you don't hate that at all. But I don't play golf and I don't 
want to stay in a gaudy overpriced hotel room so the Trump organization can 
provide nothing that I want or need. So unless I cut myself off from all human 
contact and and become completely self-sufficient I have no choice but to buy 
things from somebody you hate.

If freedom and democracy is destroyed in the US it will not be because it was 
attacked from the outside but because it rotted from the inside out, and 
January 6, 2021 was the most excruciating symptom yet of that lethal disease.

What is consciousness?

Consciousness is the state of being aware of one's thoughts, feelings, and 
surroundings. It is the subjective experience of being alive and aware. The 
exact nature of consciousness and how it arises from the brain and other 
physical systems is a topic of much debate and research in philosophy, 
psychology, neuroscience, and other fields. Some theories suggest that 
consciousness arises from the interactions of neurons in the brain, while 
others propose that consciousness is a fundamental aspect of the universe and 
cannot be fully explained by physical processes alone. Ultimately, the true 
nature of consciousness is not fully understood and is a topic of ongoing 
research and exploration.

It's measured about 70 km/sec/megaparsec. This is a direct measurement 
using red shift to measure recessional velocity, and different standard

expansion rate is 70 km/sec; at two megaparsecs the expansion rate is 140
