What the World Needs is More Curious Amateurs
Jonathon Keats is a San Francisco-based experimental philosopher who has, over the years, sold real estate in the extra dimensions of space-time proposed by string theory (he sold a hundred and seventy-two extra-dimensional lots in the Bay Area in a single day); made an attempt to genetically engineer God (God turns out to be related to the cyanobacterium); and copyrighted his own mind (in order to get a seventy-year post-life extension.
Keats's bold experiments raise serious questions and put into practice his conviction that the world needs more "curious amateurs," willing to explore publicly whatever intrigues them, in defiance of a culture that increasingly forecloses on wonder and siloes knowledge into narrowly defined areas of expertise.
Jonathan Keats: I studied philosophy in school and it was not at all what I would have expected it to be with my rather naïve concept of Socrates and Plato. It was a highly academic enterprise, which I guess shouldn’t have been surprising to me given that I was in academia, but it felt that the questions being asked were narrow and getting more so and that the answers were—well, they were answers. There was too much of an attempt to nail things down and to ultimately come up with some sort of orthodoxy, which would on top of that be intelligible only to a very small group of people who essentially were engaged in the same enterprise.
So I abandoned philosophy to attempt to do philosophy in the way that I imagined it ought to be done, in the way that I thought philosophers did it, and that I guess led me into this odd job title that I don’t really know what it means, being an experimental philosopher, but, fundamentally, I guess that what I'm trying to do is to pursue my curiosity -- that seemed to me what philosophy fundamentally was about -- but to do so in public with others in a way that was genuinely experimental, that is to say, where I didn’t know where the ideas might lead, where the hypotheses might lead, to come up with hypotheses that were provocative in a way that would engage others and that we could have some sort of a conversation that would take place in a setting, in a scenario that would be disorienting enough, reorienting people to get out of their everyday experience and to contemplate the world from a different point of view.
Goethe’s idea that you can pursue science by your own observation and extrapolating from your observation of the world and just thinking about how it might all fit together and using that as a basis for making more observations and that you can do so without any sort of special training or special aptitude, that to me is enormously appealing. He, in a sense, was the last scientist before science in the sense that we now know it, which really begins with Isaac Newton in a sense, but gets formalized thereafter as a fundamentally mathematical pursuit that is undertaken in highly rigid form, much like philosophy, really, where logic comes to have a formalized structure and where the role of the philosopher is highly regimented and specialized. Goethe was a poet as well. He was an artist. He was someone who did not believe in classifications or categorization even at the same time that he was undertaking the categorization that would become the basis of comparative anatomy. He still did not believe that these categories were absolute and certainly that they should not be absolute if we don’t wish them to be.
I do think that it is highly necessary for us collectively to come along and disrupt things. Philosophy became what it is in a sense by necessity and in a sense with an inevitability but in a sense with a sort of lack of peripheral vision, a lack of context. That is to say that it followed the general trajectory of academia and a professionalization of any discipline. The problem, of course, is that if curiosity is your curriculum, the best way in which that curriculum can be undertaken is for all of your students to cut school, and that’s a great idea, but it really won’t work at an institutional level in most universities. Perhaps Black Mountain College was the last place where this was attempted, and the school shut down pretty quickly.
So, I think that what is needed are amateurs in the true and old sense of the word, people who are in it simply for their own—out of their own interest pursuing their own curiosity, and that doesn’t really . . . it doesn’t scale up in the way that our society is built to scale things up because it doesn’t professionalize, and we have this idea that you go from amateur to professional in terms of both authority and also in terms of the degree to which resources are allocated. It doesn’t have to be that way, but in order for it not to be that way it requires that individuals simply decide to ask their own questions and that we be mad enough to go out and, often for as little as ten dollars—I think that I've actually done projects on less than that—, go out and try it, inflict it on the world and allow the world to engage.

Dark energy: The apocalyptic wild card of the universe
Dr. Katie Mack explains what dark energy is and two ways it could one day destroy the universe.
- The universe is expanding faster and faster. Whether this acceleration will end in a Big Rip or will reverse and contract into a Big Crunch is not yet understood, and neither is the invisible force causing that expansion: dark energy.
- Physicist Dr. Katie Mack explains the difference between dark matter, dark energy, and phantom dark energy, and shares what scientists think the mysterious force is, its effect on space, and how, billions of years from now, it could cause peak cosmic destruction.
- The Big Rip seems more probable than a Big Crunch at this point in time, but scientists still have much to learn before they can determine the ultimate fate of the universe. "If we figure out what [dark energy is] doing, if we figure out what it's made of, how it's going to change in the future, then we will have a much better idea for how the universe will end," says Mack.
Astrophysicists find unique "hot Jupiter" planet without clouds
A unique exoplanet without clouds or haze was found by astrophysicists from Harvard and Smithsonian.
- Astronomers from Harvard and Smithsonian find a very rare "hot Jupiter" exoplanet without clouds or haze.
- Such planets were formed differently from others and offer unique research opportunities.
- Only one other such exoplanet was found previously.

Right now, we're in the second era.
Astronomers find these five chapters to be a handy way of conceiving the universe's incredibly long lifespan.
- We're in the middle, or thereabouts, of the universe's Stelliferous era.
- If you think there's a lot going on out there now, the first era's drama makes things these days look pretty calm.
- Scientists attempt to understand the past and present by bringing together the last couple of centuries' major schools of thought.
The 5 eras of the universe
<p>There are many ways to consider and discuss the past, present, and future of the universe, but one in particular has caught the fancy of many astronomers. First published in 1999 in their book <a href="https://amzn.to/2wFQLiL" target="_blank"><em>The Five Ages of the Universe: Inside the Physics of Eternity</em></a>, <a href="https://en.wikipedia.org/wiki/Fred_Adams" target="_blank">Fred Adams</a> and <a href="https://en.wikipedia.org/wiki/Gregory_P._Laughlin" target="_blank">Gregory Laughlin</a> divided the universe's life story into five eras:</p><ul><li>Primordial era</li><li>Stellferous era</li><li>Degenerate era</li><li>Black Hole Era</li><li>Dark era</li></ul><p>The book was last updated according to current scientific understandings in 2013.</p><p>It's worth noting that not everyone is a subscriber to the book's structure. Popular astrophysics writer <a href="https://www.forbes.com/sites/ethansiegel/#30921c93683e" target="_blank">Ethan C. Siegel</a>, for example, published an article on <a href="https://www.forbes.com/sites/startswithabang/2019/07/26/we-have-already-entered-the-sixth-and-final-era-of-our-universe/#7072d52d4e5d" target="_blank"><em>Medium</em></a> last June called "We Have Already Entered The Sixth And Final Era Of Our Universe." Nonetheless, many astronomers find the quintet a useful way of discuss such an extraordinarily vast amount of time.</p>The Primordial era
<img type="lazy-image" data-runner-src="https://assets.rebelmouse.io/eyJhbGciOiJIUzI1NiIsInR5cCI6IkpXVCJ9.eyJpbWFnZSI6Imh0dHBzOi8vYXNzZXRzLnJibC5tcy8yMjkwMTEyMi9vcmlnaW4uanBnIiwiZXhwaXJlc19hdCI6MTYyNjEzMjY1OX0.PRpvAoa99qwsDNprDme9tBWDim6mS7Mjx6IwF60fSN8/img.jpg?width=980" id="db4eb" class="rm-shortcode" data-rm-shortcode-id="0e568b0cc12ed624bb8d7e5ff45882bd" data-rm-shortcode-name="rebelmouse-image" data-width="1440" data-height="1049" />Image source: Sagittarius Production/Shutterstock
<p> This is where the universe begins, though what came before it and where it came from are certainly still up for discussion. It begins at the Big Bang about 13.8 billion years ago. </p><p> For the first little, and we mean <em>very</em> little, bit of time, spacetime and the laws of physics are thought not yet to have existed. That weird, unknowable interval is the <a href="https://www.universeadventure.org/eras/era1-plankepoch.htm" target="_blank">Planck Epoch</a> that lasted for 10<sup>-44</sup> seconds, or 10 million of a trillion of a trillion of a trillionth of a second. Much of what we currently believe about the Planck Epoch eras is theoretical, based largely on a hybrid of general-relativity and quantum theories called quantum gravity. And it's all subject to revision. </p><p> That having been said, within a second after the Big Bang finished Big Banging, inflation began, a sudden ballooning of the universe into 100 trillion trillion times its original size. </p><p> Within minutes, the plasma began cooling, and subatomic particles began to form and stick together. In the 20 minutes after the Big Bang, atoms started forming in the super-hot, fusion-fired universe. Cooling proceeded apace, leaving us with a universe containing mostly 75% hydrogen and 25% helium, similar to that we see in the Sun today. Electrons gobbled up photons, leaving the universe opaque. </p><p> About 380,000 years after the Big Bang, the universe had cooled enough that the first stable atoms capable of surviving began forming. With electrons thus occupied in atoms, photons were released as the background glow that astronomers detect today as cosmic background radiation. </p><p> Inflation is believed to have happened due to the remarkable overall consistency astronomers measure in cosmic background radiation. Astronomer <a href="https://www.youtube.com/watch?v=IGCVTSQw7WU" target="_blank">Phil Plait</a> suggests that inflation was like pulling on a bedsheet, suddenly pulling the universe's energy smooth. The smaller irregularities that survived eventually enlarged, pooling in denser areas of energy that served as seeds for star formation—their gravity pulled in dark matter and matter that eventually coalesced into the first stars. </p>The Stelliferous era
<img type="lazy-image" data-runner-src="https://assets.rebelmouse.io/eyJhbGciOiJIUzI1NiIsInR5cCI6IkpXVCJ9.eyJpbWFnZSI6Imh0dHBzOi8vYXNzZXRzLnJibC5tcy8yMjkwMTEzNy9vcmlnaW4uanBnIiwiZXhwaXJlc19hdCI6MTYxMjA0OTcwMn0.GVCCFbBSsPdA1kciHivFfWlegOfKfXUfEtFKEF3otQg/img.jpg?width=980" id="bc650" class="rm-shortcode" data-rm-shortcode-id="c8f86bf160ecdea6b330f818447393cd" data-rm-shortcode-name="rebelmouse-image" data-width="481" data-height="720" />Image source: Casey Horner/unsplash
<p>The era we know, the age of stars, in which most matter existing in the universe takes the form of stars and galaxies during this active period. </p><p>A star is formed when a gas pocket becomes denser and denser until it, and matter nearby, collapse in on itself, producing enough heat to trigger nuclear fusion in its core, the source of most of the universe's energy now. The first stars were immense, eventually exploding as supernovas, forming many more, smaller stars. These coalesced, thanks to gravity, into galaxies.</p><p>One axiom of the Stelliferous era is that the bigger the star, the more quickly it burns through its energy, and then dies, typically in just a couple of million years. Smaller stars that consume energy more slowly stay active longer. In any event, stars — and galaxies — are coming and going all the time in this era, burning out and colliding.</p><p>Scientists predict that our Milky Way galaxy, for example, will crash into and combine with the neighboring Andromeda galaxy in about 4 billion years to form a new one astronomers are calling the Milkomeda galaxy.</p><p>Our solar system may actually survive that merger, amazingly, but don't get too complacent. About a billion years later, the Sun will start running out of hydrogen and begin enlarging into its red giant phase, eventually subsuming Earth and its companions, before shrining down to a white dwarf star.</p>The Degenerate era
<img type="lazy-image" data-runner-src="https://assets.rebelmouse.io/eyJhbGciOiJIUzI1NiIsInR5cCI6IkpXVCJ9.eyJpbWFnZSI6Imh0dHBzOi8vYXNzZXRzLnJibC5tcy8yMjkwMTE1MS9vcmlnaW4uanBnIiwiZXhwaXJlc19hdCI6MTYxNTk3NDQyN30.gy4__ALBQrdbdm-byW5gQoaGNvFTuxP5KLYxEMBImNc/img.jpg?width=980" id="77f72" class="rm-shortcode" data-rm-shortcode-id="08bb56ea9fde2cee02d63ed472d79ca3" data-rm-shortcode-name="rebelmouse-image" data-width="1440" data-height="810" />Image source: Diego Barucco/Shutterstock/Big Think
<p>Next up is the Degenerate era, which will begin about 1 quintillion years after the Big Bang, and last until 1 duodecillion after it. This is the period during which the remains of stars we see today will dominate the universe. Were we to look up — we'll assuredly be outta here long before then — we'd see a much darker sky with just a handful of dim pinpoints of light remaining: <a href="https://earthsky.org/space/evaporating-giant-exoplanet-white-dwarf-star" target="_blank">white dwarfs</a>, <a href="https://earthsky.org/space/new-observations-where-stars-end-and-brown-dwarfs-begin" target="_blank">brown dwarfs</a>, and <a href="https://earthsky.org/astronomy-essentials/definition-what-is-a-neutron-star" target="_blank">neutron stars</a>. These"degenerate stars" are much cooler and less light-emitting than what we see up there now. Occasionally, star corpses will pair off into orbital death spirals that result in a brief flash of energy as they collide, and their combined mass may become low-wattage stars that will last for a little while in cosmic-timescale terms. But mostly the skies will be be bereft of light in the visible spectrum.</p><p>During this era, small brown dwarfs will wind up holding most of the available hydrogen, and black holes will grow and grow and grow, fed on stellar remains. With so little hydrogen around for the formation of new stars, the universe will grow duller and duller, colder and colder.</p><p>And then the protons, having been around since the beginning of the universe will start dying off, dissolving matter, leaving behind a universe of subatomic particles, unclaimed radiation…and black holes.</p>The Black Hole era
<img type="lazy-image" data-runner-src="https://assets.rebelmouse.io/eyJhbGciOiJIUzI1NiIsInR5cCI6IkpXVCJ9.eyJpbWFnZSI6Imh0dHBzOi8vYXNzZXRzLnJibC5tcy8yMjkwMTE2MS9vcmlnaW4uanBnIiwiZXhwaXJlc19hdCI6MTYzMjE0OTQ2MX0.ifwOQJgU0uItiSRg9z8IxFD9jmfXlfrw6Jc1y-22FuQ/img.jpg?width=980" id="103ea" class="rm-shortcode" data-rm-shortcode-id="f0e6a71dacf95ee780dd7a1eadde288d" data-rm-shortcode-name="rebelmouse-image" data-width="1400" data-height="787" />Image source: Vadim Sadovski/Shutterstock/Big Think
<p> For a considerable length of time, black holes will dominate the universe, pulling in what mass and energy still remain. </p><p> Eventually, though, black holes evaporate, albeit super-slowly, leaking small bits of their contents as they do. Plait estimates that a small black hole 50 times the mass of the sun would take about 10<sup>68</sup> years to dissipate. A massive one? A 1 followed by 92 zeros. </p><p> When a black hole finally drips to its last drop, a small pop of light occurs letting out some of the only remaining energy in the universe. At that point, at 10<sup>92</sup>, the universe will be pretty much history, containing only low-energy, very weak subatomic particles and photons. </p>The Dark Era

<p>We can sum this up pretty easily. Lights out. Forever.</p>Five collectibles with better returns than the stock market
People often make a killing in stocks, but there are other ways to potentially turn major profits.
- Outside of stocks and bonds, some people make money investing in collectibles and make a fair amount on them.
- One stamp even sold for a billion times its face value.
- The extreme dependence on future collectability, however, limits the potential of most of these opportunities.
Pokémon Cards
<iframe width="730" height="430" src="https://www.youtube.com/embed/hVUmTaSoB5Y" frameborder="0" allow="accelerometer; autoplay; clipboard-write; encrypted-media; gyroscope; picture-in-picture" allowfullscreen></iframe><p> For those who weren't content to catch them all in a video game came a trading card game where you could collect them all. Some classic cards have gained tremendous stature among collectors and Pokéfanatics and sell for extremely high prices. </p><p> An older card featuring Charizard, a fire breathing dragon, regularly sells for thousands <a href="https://www.lifesuccessfully.com/gaming-articles/the-most-wanted-pokemon-cards-charizard#/" target="_blank" rel="noopener noreferrer">online</a>. Given that the card could be purchased for a couple dollars in 1999, this is quite the return. A particular pack of Pokémon cards, which cost $5 in 2003, now sells for $650, 130 times the original asking <a href="https://adamrybko.medium.com/stocks-or-pokemon-cards-an-introduction-to-alternative-investing-32fe499083c4" target="_blank" rel="noopener noreferrer">price</a>. </p><p> Of course, not every card will fetch these high prices. Buying cards as an investment is tricky. You have to essentially guess at which cards will be considered highly valuable at a later date and will be unable to collect dividends before selling them.</p><p> Furthermore, you have to presume that people will be collecting the cards years after buying them. While Pokémon has remained popular, it is a bit of an outlier in terms of enduring success.</p>Sneakers

<p> People from all walks of life—from skateboarders to the First Lady of the <a href="https://www.rappler.com/newsbreak/in-depth/imelda-marcos-shoes-mixed-legacy" target="_blank" rel="noopener noreferrer">Philippines</a>—enjoy collecting shoes. An entire subculture exists for people interested in collecting sneakers, and some people make quite a profit in it.</p><p> The Nike SB Dunk Low Reese Forbes Denims, priced initially at $65 in 2002, are commonly valued in the thousands of dollars now. The Nike Air Jordan 1 Retro High x Off White "Chicago" shoe sold for $190 a mere four years ago, but now sells for $4000 a <a href="https://sixfiguresneakerhead.com/sneaker-model-return-alternative-investment-stock-x-reseller/" target="_blank" rel="noopener noreferrer">pair</a>. </p><p> A <a href="https://www.huffpost.com/entry/sneakers-good-investment_n_5bd1f5ebe4b0d38b588143ee?guccounter=1&guce_referrer=aHR0cHM6Ly93d3cuZ29vZ2xlLmNvbS8&guce_referrer_sig=AQAAALOu0F9zs5DBHHOIjMgHOZR6K88W3rZkyD3ftBMz2nzlHfoxD4MS2Iz1vF3H-a4_xzOWIIrsJyv76Gj6xwUXaRIRdjq7M2m7I6-lxihWIcEfs7F9PgOwnx82JXPfXmWL7-RQlNUufOyvd8V6TCzMEYrEjzMXVU77IWk9MjOEtsln" target="_blank" rel="noopener noreferrer">Huffington Post</a> article points out that most of these shoes offered better returns than gold over the same period. The same article quotes YouTube personality <a href="https://www.youtube.com/user/mrFOAMERSIMPSON" target="_blank" rel="noopener noreferrer">Mr. Foamer Simpson</a> and his explanation of the difficulties of making money on shoes:</p><p style="margin-left: 20px;"> "There's a guessing game or element of unpredictability that makes it exciting for some collectors. With sneakers, you kind of never know. Sure, you know what sneakers are more limited or which ones were harder to get, but even with that, it fluctuates a lot. A sneaker that was very valuable two years ago might all of a sudden crash and no longer be valuable."</p>Toys of all kinds

That often translates into old and rare toys fetching insane prices at auction.</p><p> Beanie Babies, those little stuffed animals from the 1990s, once sold for thousands of dollars <a href="https://www.thefiscaltimes.com/2015/03/02/How-Great-Beanie-Baby-Bubble-Went-Bust" target="_blank" rel="noopener noreferrer">online</a>, not bad considering they originally cost $5. LEGO sets, particularly those featuring well-known franchises like Star Wars, can sell for hundreds <a href="https://finance.yahoo.com/news/20-geeky-collectibles-could-millions-201624881.html" target="_blank" rel="noopener noreferrer">online</a>. </p><p> As with Pokémon cards, the success stories are dependent on what people are interested in collecting long after most people forgot the toy existed.<strong> </strong>While some collectors have ideas on how to gauge what might or might not end up being valuable later, there seems to be a considerable amount of luck involved.</p>Stamps
<p> The hobby of kings has occasionally made some people as rich as one, with rare stamps and extensive collections fetching high prices at auction.</p><p> One of the famous "Inverted Jenny" stamps, a rare misprint showing an upside-down airplane, sold for $1,593,000 at <a href="https://www.linns.com/news/us-stamps-postal-history/2018/november/nov-15-jenny-invert-sale-record.html" target="_blank" rel="noopener noreferrer">auction</a>. The most valuable stamp in the world, the British Guiana 1c magenta, last sold for $9,480,000, a billion times its face <a href="http://www.sothebys.com/en/auctions/2014/magenta-n09154.html" target="_blank" rel="noopener noreferrer">value</a>. For those interested in a shorter-term investment, the USA Forever stamp has gained a face value of 75% since its introduction and can still be used to send a letter.</p>Coins

Older coins made of precious metals are also highly valued; a silver dollar from 1804 sold for nearly $2,000,000 at <a href="https://coins.thefuntimesguide.com/rare_coin_prices/" target="_blank" rel="noopener noreferrer">auction</a>. Even old wheat pennies can sell for a couple of dollars today. </p><p> While these collectibles can provide high returns on your investment in them, they don't provide dividends, and their value is entirely dependent on how much collectors are willing to pay for the particular item you have. As a couple of the above examples show, tastes can change and leave your investment worthless. If you have some luck, an eye for trends, and the good fortune not to have thrown out your old stuff, you might be able to make a fair amount on it. </p><p> Of course, if you manage to get rich because you found an old coin in your desk after reading this article, be sure to remember who wrote it. </p>
