There are basically two routes to so called 'scientific' multi-universe or alternate reality theories, from the cosmology and from quantum mechanics. According to general relativity Spacetime is shaped by matter. The universe that we are part of is a particular shape. Some models are closed shapes, some are open. In either case the universe is not infinite because spacetime cannot extend very far beyond the matter that shapes and creates it. It is difficult to imagine the universe as a closed four dimensional shape without picturing it as 'floating' in something, perhaps another infinite space. However this image is not justified by the science and implies further dimensions for the four dimensional universe to be in. If someone wished to speculate about this in a non-scientific way they could imagine an infinite number of 'island universes' dotted about in this multi-dimensional space much as galaxies are spread out in the four dimensional space that we know about. However these universes could have no contact with each other and could not exchange information (I am aware that there are 'wormhole speculations about transference of information but these are ot based on testable science and presume that alternative universes exist to create wormholes to). From a scientific point of view they could not be detectable and hence effectively do not exist. In many scientific theories there are often terms of equations that are neglected for this very reason. Non-interaction is effectively non-existence. It is in this unexplorable realm that believers place their gods and it is no more justifiable for scientists. The many universe quantum theories are an attempt to resolve problems of superposition of states. When these states decohere there are problems for classically deterministic systems. The supposed solution offered by multi-universe theories is that all possible states of a quantum system lead to real observable solutions in alternate universes. This implies that effectively an infinite number of mature alternative universes come into being every moment as a result of each alternative state cross-referencing with every other alternative state. There are many more problems with this than the obvious one of where does all this matter and energy come from and in what ‘space’ does it exist. A damning consequence for the speculation is that every possible alternative universe will exist. This means that even if there were a experimentally testable consequence of this hypothesis there are universes where scientific experimentation always fails and hence 'proves' that the hypothesis itself is incorrect. As a solution to anything this hypothesis is not only untestable but also must refute itself. Whatever this hypothesis is it is not a scientific one and has no meaning in terms of explaining experience. Given that there are at least ten alternative hypothesise to resolve the problem of interaction between quantum world and the classical world that do not require the creation of infinite universes at each moment in time (i.e. everything happens because everything is possible) it is unnecessary to leap to an unscientific metaphysical one that creates more problems than it resolves (personally I favour a variation of einselection).

"One way the internet distorts our picture of ourselves is by feeding the human tendency to overestimate our knowledge of how the world works," writes philosophy professor Michael Patrick Lynch.
- Social media echo chambers have made us overconfident in our knowledge and abilities.
- Social psychologists have shown that publicly committing to an opinion makes you less willing to change your mind.
- To avoid a descent into epistemic arrogance and tribalism, we need to use social media with deep humility.

"The Internet of Us becomes one big reinforcement mechanism, getting us all the information we are already biased to believe, and encouraging us to regard those in other bubbles as misinformed miscreants. We know it all—the internet tells us so."</p> <p>In other words, the internet encourages epistemic arrogance—the belief that one knows much more than one does. The internet's tailored social media feeds and algorithms have herded us into echo chambers where our own views are cheered and opposing views are mocked. Sheltered from serious challenge, celebrated by our chosen mob, we gradually lose the capacity for accurate self-assessment and begin to believe ourselves vastly more knowledgeable than we actually are. </p>
The consequences of public commitment<p>But it's not just the social reinforcement mechanism of like-minded crowds that is killing intellectual humility. It's also our own digital trails—the permanent records of our previous opinions.</p> <p>"Here's another way that Twitter may harm democratic debate," New York University Stern School of Business professor Jonathan Haidt <a href="https://twitter.com/jonhaidt/status/1214008345893523457" target="_blank">tweeted</a> in January 2020, attaching a couple pages from Robert Cialdini's seminal marketing book <a href="https://www.amazon.com/Influence-Practice-Robert-B-Cialdini/dp/0205609996/ref=sr_1_1?keywords=influence+cialdini&qid=1580757318&s=books&sr=1-1" target="_blank"><em>Influence</em></a>. "Publicly committing to an answer makes people less receptive to info suggesting they were wrong." In the excerpt from <em>Influence</em>, Cialdini summarizes an experiment by social psychologists Morton Deutsch and Harold Gerard in which three groups of students were shown a set of lines. One group was asked to write down their estimates of the lines' length and turn their estimates in to the experimenter; the second group was asked to write down their estimates on a Magic Pad, then erase the pad before anyone could see; and the third group didn't write down their estimates at all. After the students were shown new evidence that suggested their original estimates were inaccurate, Cialdini writes: </p> <p style="margin-left: 20px;">The students who had never written down their first choices were least loyal to those choices. . . . [B]y far, it was the students who had publicly recorded their initial positions who most resolutely refused to shift from those positions later. Public commitment had hardened them into the most stubborn of all.</p> <p>Thanks to social media, most of us have publicly committed ourselves to our opinions. Our feeds are years of publicly published diary entries with our frozen-in-time thoughts on politics, news, relationships, religion, and more. Savvy social media users worry about how their digital trails will affect their future job prospects, but few people worry about how their digital trails might be affecting their own minds. By committing ourselves publicly to our present opinions, we may be hardening ourselves to future information that would otherwise change our minds—and thereby foreclosing upon our capacity for intellectual humility. </p>

"The chances are good that it was a kind of conversation that left you feeling smarter.

None of us can ever have the full lock on truth. We can only see the world from a particular vantage point. And that means that our knowledge is going to have special insight because of our vantage point, but it's also going to be limited because of our vantage point. And so that limited knowledge that we can have about the world means that we must enter into any conversation with a deep sense of humility, because I need you to help me fill in my knowledge gaps. Right? And you need me. </p> <p>Consider this: Social media presents limitless possibilities for good, learning conversations—like deep canvassing—between strangers across the globe. If each social media user approached online interactions from a position of deep intellectual humility, recognizing that every other user represents an opportunity to fill knowledge gaps and grow, our social networks could become an unprecedented engine of human progress—instead of the drag-down into tribalism they currently seem to be. </p>
Health officials in China reported that a man was infected with bubonic plague, the infectious disease that caused the Black Death.
- The case was reported in the city of Bayannur, which has issued a level-three plague prevention warning.
- Modern antibiotics can effectively treat bubonic plague, which spreads mainly by fleas.
- Chinese health officials are also monitoring a newly discovered type of swine flu that has the potential to develop into a pandemic virus.
Bacteria under microscope
needpix.com<p>Today, bubonic plague can be treated effectively with antibiotics.</p><p style="margin-left: 20px;">"Unlike in the 14th century, we now have an understanding of how this disease is transmitted," Dr. Shanthi Kappagoda, an infectious disease physician at Stanford Health Care, told <a href="https://www.healthline.com/health-news/seriously-dont-worry-about-the-plague#Heres-how-the-plague-spreads" target="_blank">Healthline</a>. "We know how to prevent it — avoid handling sick or dead animals in areas where there is transmission. We are also able to treat patients who are infected with effective antibiotics, and can give antibiotics to people who may have been exposed to the bacteria [and] prevent them [from] getting sick."</p>
This plague patient is displaying a swollen, ruptured inguinal lymph node, or buboe.
Centers for Disease Control and Prevention<p>Still, hundreds of people develop bubonic plague every year. In the U.S., a handful of cases occur annually, particularly in New Mexico, Arizona and Colorado, <a href="https://www.cdc.gov/plague/faq/index.html" target="_blank">where habitats allow the bacteria to spread more easily among wild rodent populations</a>. But these cases are very rare, mainly because you need to be in close contact with rodents in order to get infected. And though plague can spread from human to human, this <a href="https://www.healthline.com/health-news/seriously-dont-worry-about-the-plague#Heres-how-the-plague-spreads" target="_blank">only occurs with pneumonic plague</a>, and transmission is also rare.</p>
A new swine flu in China<p>Last week, researchers in China also reported another public health concern: a new virus that has "all the essential hallmarks" of a pandemic virus.<br></p><p>In a paper published in the <a href="https://www.pnas.org/content/early/2020/06/23/1921186117" target="_blank">Proceedings of the National Academy of Sciences</a>, researchers say the virus was discovered in pigs in China, and it descended from the H1N1 virus, commonly called "swine flu." That virus was able to transmit from human to human, and it killed an estimated 151,700 to 575,400 people worldwide from 2009 to 2010, according to the Centers for Disease Control and Prevention.</p>There's no evidence showing that the new virus can spread from person to person. But the researchers did find that 10 percent of swine workers had been infected by the virus, called G4 reassortant EA H1N1. This level of infectivity raises concerns, because it "greatly enhances the opportunity for virus adaptation in humans and raises concerns for the possible generation of pandemic viruses," the researchers wrote.
The word "learning" opens up space for more people, places, and ideas.
- The terms 'education' and 'learning' are often used interchangeably, but there is a cultural connotation to the former that can be limiting. Education naturally links to schooling, which is only one form of learning.
- Gregg Behr, founder and co-chair of Remake Learning, believes that this small word shift opens up the possibilities in terms of how and where learning can happen. It also becomes a more inclusive practice, welcoming in a larger, more diverse group of thinkers.
- Post-COVID, the way we think about what learning looks like will inevitably change, so it's crucial to adjust and begin building the necessary support systems today.
