But in doing so it reveals much more, making it of interest not only to astronomers but also to cosmologists and physicists. Because the constant represents the expansion rate at any particular moment in the universe’s long history, measuring its value over time provides an expansive view of how the universe evolves over the eons, giving researchers crucial clues to our cosmic origins and future.
Somehow beckoned by the void, billions of outward-rushing galaxies also feel the collective gravitational pull of everything in the rearview mirror trying to tug them back. The Hubble constant reflects the sum total of all the stuff in the universe and the forces acting on it—weighing in on whether gravity or the void will ultimately win this intergalactic tug-of-war."
My question has always been 'expansion' in relation to what? What expanse contains the expansion in order to provide the perspective to derive a quantified unit of measure? The thing itself? This question also applies to the speculation about the multi-verse theory: What contains all these multi variations? The thing itself? That's almost a cosmic tautology. One might as well quantify a singularity. Or could it be we're simply inside an awesome cosmic opical illusion created by a genius intellect for our own amazement and amusement? My head hurts...
Have We Mismeasured the Universe?
"But this seeming triumph has recently led Knox and his colleagues into controversy and confusion. If cosmologists’ prevailing theories of the universe are correct, then all the ways of calculating the Hubble constant in the modern era should give the same answer. The value derived by extrapolating from the ancient sound waves should match up exactly with the value derived from independent studies of the light from distant stars and galaxies. In reality, a series of studies show the two approaches yield a vexing disagreement—and the more diligently researchers attack the problem, the more definitive the conflict seems to be.
There is one way all of the measurements can be correct, and that is if something is wrong with scientists’ interpretations of those measurements. Knox notes everything we know about the origin of the sound horizon depends on a theoretical model of how the universe behaved during its unseen initial 380,000 years. If the models are wrong and the size of the sound horizon is different than what they predict, that adjustment would change all of the numbers derived from it, including the Hubble constant."
Extrapolating interpretations derived from two approaches to prevailing theories. No settled science here. One may as well declare they've bottled lightening...
The World Might Actually Run Out of People
No. It won't. By design. The author's first mistake was positing the U.N. as a 'well-regarded authority on everything from public health to food security and global economics.' Whatever. As long as the world doesn't run out of dogs and good books, I'm flexible on the people thing.
This tiny fish can recognize itself in a mirror. Is it self-aware?
"The cleaner wrasse joins humans, chimpanzees, dolphins, and a select few other animals that can pass a long-standing intelligence test."
But not cats. Or Marxists. They both only respond to their own power.
If Global Warming Is Killing Us, Why Is Global Life Expectancy Increasing?
"And this is especially relevant since the very factors that are blamed for climate change — such as a the high productivity levels and growing standards of living made possible by an industrialized modern society — are the very things that also improve life expectancy. Greater access to insulated housing, air conditioning, heating, medical care, medical research, refrigeration, and clean water are all enhanced by modern industrial economies."
In short, technology spread by capitalism has solved more global problems than the greedy farce of 'global warming' claims to inflict. As such, I'll only consider global warming a dire emergency when the elites promoting this greedy farce start acting like it's a dire emergency.
Scientists figure out what makes beer good for you
"And, while beer brewers the world over are unlikely to change their recipes, the scientists hope to use the discovery to create new medicines."
'New medicines.' That will make you a big hit with the ladies at the pub...
