Airbrush

Thanks for the info. Suppose someone sneezes or coughs and droplets of various sizes are ejected. These droplets float in the air, the heaviest ones drop to the ground. All the other droplets evaporate in minutes. That means the droplets all shrink in size until they completely evaporate and the virus is left dry and light as smoke. Then, as you said, sunlight kills the dry virus in minutes. That is why outdoor infections are low?

Here is my Coronavirus question for anyone. If I am jogging around my neighborhood in the morning, and somebody with Coronavirus sneezed or coughed at the sidewalk in front of their house, just before I pass by the very spot, how long is the virus dangerous to me? Even if the wind speed is almost zero, the droplets will drift, dilute, and disburse, but it could drift in the wrong direction for someone passing by. Don't the droplets evaporate leaving the virus high and dry? Then does the sunlight not kill the high and dry virus? How long does it take sunlight to kill the airborne virus after a cough or sneeze?

Here is a major discrepancy between the number of torpedoes and bombs struck Yamato. According to the Youtube: "In just over 2 hours, Yamato, Yahagi, and 4 of the 8 destroyers had been sent to the bottom. The operation became a giant "turkey shoot" for the USN. Yamato herself absorbed a mind-boggling 22 torpedoes, and at least as many bombs" According to Wikipedia.org: "From the first attack at 12:37 to the explosion at 14:23, Yamato was hit by at least 11 torpedoes and 6 bombs. There may have been two more torpedo and bomb hits, but this is not confirmed..." When I read thru the Wiki story on the sinking of Yamato, I counted 13 torpedo hits and 9 bomb hits. https://en.wikipedia.org/wiki/Japanese_battleship_Yamato

The world HAS been getting better, until population growth, climate change, and water and other resource shortages intersect...soon.

Could you please explain this model? How does this tell you that 11 billion is the max? What about fresh water shortages? How about wars over resources? I always thought that unless people intentionally restrict population growth, there would be a big, accidental war that eliminates half the population in the aftermath of a nuclear exchange. Oops! 😲

Rather than colonizing Mars, the Moon, asteroids, or a giant solar-system cruiser, we should colonize Earth! We could build bunkers that resist the worst natural disasters. People living near the ocean should be prepared with a tsunami and hurricane shelter. Establish self-sufficient settlements in areas previously uninhabited, such as deserts that are near the ocean, Northern Canada, or Antarctica. Such independent settlements would use solar and wind power, and enough renewable biofuels (those in warm climates) to satisfy energy required for a growing settlement, and pump sea water inland to desalinate. Such settlements could produce food on farms and use surplus fresh water to plant trees where trees and other vegetation had not grown before. Sooner or later governments will place restrictions on population. Like China's one child per couple policy, but maybe not that strict. Maybe a 2-child limit. Maybe medicine would progress to the point that people could know in advance it they should have children. Maybe they learn their children would have genetic problems, so they decide to not have children.

Excellent post! Just what I wanted to hear. Thank you. +1 for that. Hawking should not be thought as the expert on human survival prospects. Humanity may survive much longer than 100 years, but as you pointed out, it could be post-apocalyptic survival of a few, or even many people surviving, but grand plans for space exploration would be put on hold. Arthur C Clark thought in 1982 that by 2010 we could have a huge spacecraft orbiting Jupiter.

Here is a more heartbreaking angle. If this don't bring you to tears, you ain't human.

Ships that were not defended by air cover, had slim chance to fight off 200 warplanes using only AA batteries. So everybody involved, Americans and Japanese, knew what the outcome would be. This was an Alamo unfolding. So the US warplanes initially stayed out of reach of accurate AA fire to let them waste ammo. Then the Hellcats and Corsairs could decimate the AA batteries to make the bomber and torpedo runs safer. Just my guess. "In just over 2 hours, Yamato, Yahagi, and 4 of the 8 destroyers had been sent to the bottom. The operation became a giant "turkey shoot" for the USN. Yamato herself absorbed a mind-boggling 22 torpedoes, and at least as many bombs, before she capsized and exploded, taking over 3000 of her crew of 3300 down with her. The total Japanese losses in the battle were 4000 men. The USN lost 12 planes and 10 pilots. The age of the battleship was over."

Ok you are correct, it would by necessity be a generational spaceship. I confused interstellar travel for generational travel. But do you agree with Hawking that we don't have much time for anything but to try to fix Earth and maybe build another generation of telescopes to detect planets with life on them? Forget about sending probes to other stars, much less sending people to other stars. Will 100 years be enough time to BEGIN terraforming Mars? Maybe a few settlements can be established on Mars, but what will a few meager colonies do AFTER Earth is done? No more help from home. They won't be able to terraform Mars, just survive for a while.

Here are a couple of interesting CGI Youtubes I found. They are 10 minutes each. Maybe any other enthusiasts of the history of WW2 would be interested. They are produced by Japanese, so I think they tried to be accurate about their famous battleship. Yamato is to the Japanese what the Alamo is the Americans, according to the producers of these youtubes. When you watch the videos, notice that for quite a few minutes the 200+ US warplanes swarmed the Yamato without attacking. Why is that? Then pay attention to the part where 3 Helldivers drop 2 bombs each (6 bombs) and they all land within a couple of seconds in the same general area. At the end the Yamato capsizes and there is a giant explosion under water. Yamato Youtube #3 Yamato Youtube #4

Not enough explaining yet. What does FTFY and FFS mean? Would you care to elaborate? What does Satan's grudge have to do with anything related to Qanon? Again I ask, does the Qanon manifesto posted above by Ole B sound spontaneous or scripted?

Certainly priority #1 is FIX THIS PLANET. After that is done (tall order), what can we do for fun? What is your NEXT priority for space exploration? Terraforming Mars or building Terminator robots? Remember we may have only about 100 more years to do it.

That's right, a little "understanding" and sympathy for the freedom fighters against Satan? You have a little explaining to do.

If anyone with the courage to read a Qanon manifesto would read what Ole B wrote, please tell me if it sounds like someone wrote all of that spontaneously, or if it sounds like a script that internet trolls (Russians?) read whenever someone, such as myself, expresses an interest in how they know what they know. I did go down 2 rabbit holes, Frazzledrip and John Podesta's artwork, and I could not find anything of substance, just blurred photos, weird sound effects, and outrageous claims about them. https://www.bing.com/videos/search?q=frazzledrip+video&docid=607993745213688016&mid=136D7AA32F86143ED365136D7AA32F86143ED365&view=detail&FORM=VIRE

I am not suggesting generational craft. Remember what Stephen Hawking said, that humanity has about 100 more years before our extinction. So how do you want to spend the next 100 years? Terraforming Mars, building Terminator robots, or exploring the solar system? People going to other stars seems farther and farther away than ever. Even sending high-speed probes to the nearest stars seems less likely than just being content to view evidence of life on other planets in the time we have left. https://futurism.com/stephen-hawking-humanity-only-has-100-years-left-on-earth-before-doomsday

How long would it take to terraform Mars? Mars is a nice place to visit, but you wouldn't want to live there. Terraforming Mars will be too costly and a lower priority, compared to giving humanity mobility around the solar system. My spaceship can orbit Mars in the comfort of one G with temperature controlled, video games, all you can eat, and shielded from cosmic rays, like in Star Trek, but not to the stars, just around our neighborhood. We can visit Titan, Enceladus, Europa, and other fine destinations. 😃 The next few hundred years may be very tough for humanity considering population growth, climate change, nuclear terrorism, natural disasters, etc, all point to doing more with less. Humanity will become very budget conscious. Terraforming Mars, and Terminator robots, should be a lower priority than comfortable mobility around the solar system. After you have your comfortable spaceships, you can visit asteroids that have water-ice and minerals you need, then hollow them out. Live inside of asteroids. They would rotate providing one G for people standing inside with their heads pointing towards the center of the asteroid. That would be better than terraforming Mars.

Salvador Dali was famous for saying "I know what I eat, but I don't know what I do."

Terraforming planets will take a back seat to building spacecraft that can be "all the comforts of home." Why make the effort to terraform Mars when you could much easier build a giant spacecraft that can travel for decades without needing anything, except to stop occasionally at an asteroid to collect water-ice for water, air and fuel, and some useful minerals.

Good question. Maybe when you tickle yourself, you already know exactly the location and the kind tickle you intend. When somebody else tickles you, you cannot anticipate location and kind of tickling? After my answer I googled "why can't i tickle myself" and I got this: "...basically comes down to your cerebellum having the ability to predict the tickle, therefore cancelling it out before the sensation takes over. "Our studies at University College London have shown that the cerebellum can predict sensations when your own movement causes them but not when someone else does," Blakemore explained to Scientific American. "When you try to tickle yourself, the cerebellum predicts the sensation and this prediction is used to cancel the response of other brain areas to the tickle." https://www.sciencealert.com/the-scientific-reason-you-can-t-tickle-yourself

As usual I'm trying to "figure out" obscure subjects. I stumbled upon a Qanon believer when I was listening to music on Youtube. It is a nice version of Bob Marley's song "Babylon System." If you want to listen to it, I posted the song at the end of this post. In the song Bob Marley sings: Babylon system is the vampire, yea! Suckin' the children day by day, yeah! Me say de Babylon system is the vampire, falling empire, Suckin' the blood of the sufferers, yeah! Building church and university, wooh, yeah! Deceiving the people continually, yeah! Me say them graduatin' thieves and murderers Look out now they suckin' the blood of the sufferers A couple of Qanon enthusiasts commented about the words "vampire sucking the children day by day" that it referred to Hillary Clinton and the "Hollywood Elites" who are Satantic, pedophile, cannibal, vampires who torture children to get "adrenochrome" from their blood. It's supposed to keep them young. They suggested that Bob Marley could foresee Qanon and was calling them out. Ole B posted: "Knowing the elites drink blood for adrenachrome and practice human sacrifice gives this song a whole new feeling. I wish I woke up earlier." I replied to call foul, that Qanon was an absurd conspiracy theory with no factual basis, and saying Bob Marley was referring to Qanon was disgusting and they were LIARS!! Marley was just being figurative not literal. One believer replied to me, see below. This should give some insight into the mind of a believer. I asked him how he knew something that he cannot know about. His reply was: Ole B: "It is hard to believe. It's also uncomfortable to believe. I sometimes wish I could unthink this shit and go back to normal life. It's hard to be happy knowing Satanists have been ruining the world on a scale I could've never imagined. I had hope for the future 3 months ago now I expect war anytime soon. Keep your family and friends close bro. Stay safe. Peace. There’s nothing I could provide as solid evidence. Just a bunch of coincidences and gut feeling. I didn’t believe this stuff either but one night 3 months ago I discovered some disturbing things about actors while watching interviews on you tube. In the comment section of those videos there were strange comments and repetitive use of certain symbols ex:🤔🤫👌🦋🍕. I followed the people posting those comments to other channels on youtube where people seemed to be recently systematically causing chaos around the world. I followed some names mentioned in these videos and in the comments to social media accounts of what appeared to me to be Cartel members that seemed to be selling and kidnapping children. Advertising things suspiciously, sort of in the same way Wayfair later came under suspicion for their overpriced cabinets. I was distraught, my whole world was changed that night. I'm not a man of faith but I prayed for the first time in over 20 years. I mentioned what I found about the actors to a few friends the next day at work. Leaving out the stuff about the children till I could do further research. The day after that I was approached by a man I knew for 4 years who called me a sheep and threatened my life. The four years I knew this man he was one of the kindest and politically smart people I knew so I was absolutely shocked. I looked into his social media that night and I see the same symbolisms, the same odd advertisements like a fruit for $500 with a small brown child sitting on it. After that I started research into conspiracies like pizzagate and the Illuminati. I can’t prove it but I'm 100% sure of what I believe and I urge everybody who’s ready to accept it to look into it for themselves. I believe a mass awaking might stop this satanic insanity and I also believe it might be part of such an elaborate and well thought out plan that it may be beyond our power to stop it. From what I've gathered they are trying to create a new world under communism run by Satanist and pedophiles. Many people need to die for this to happen. They are trying to destroy and rewrite history." There it is, from a true believer. Could Q be a Russian troll sewing chaos in the US? Anyone want to share what they know about Qanon? They like Trump, so Trump likes them back.

Yeah humans have other problems to deal with like climate change and pandemics before fooling around with a lark like this. The terminator robot is very sophisticated. It is indistinguishable from a real person. And it is very tough, almost indestructible. Maybe in a couple of hundred years, if we survive other problems.

My favorite subject on this web site is Astronomy & Cosmology. Too bad there is not more conversation here. The idea of a "positively-curved" universe, where if you really travel in a totally straight line, you may end up at your starting point is the most difficult idea I have yet encountered. It is impossible for me to think in "flat-lander."☹️ Anyone have a more understandable analogy for global curvature?😃 Or at least explain how 3-d space can be so curved.

Very funny remarks above, but the question has not been answered. How long until robotic and AI technology reach the level of a terminator robot, just like in the first Terminator movie? My guess is it will take a long time, maybe 100 years?
