Hey Bill Nye! Do You Believe in Ghosts and the Afterlife?
Bill Nye tackles a tough question that every person alive has been hung up on – what happens after we die? Where does our life energy go?
Bill Nye, scientist, engineer, comedian, author, and inventor, is a man with a mission: to help foster a scientifically literate society, to help people everywhere understand and appreciate the science that makes our world work. Making science entertaining and accessible is something Bill has been doing most of his life. In Seattle Nye began to combine his love of science with his flair for comedy, when he won the Steve Martin look-alike contest and developed dual careers as an engineer by day and a stand-up comic by night. Nye then quit his day engineering day job and made the transition to a night job as a comedy writer and performer on Seattle's home-grown ensemble comedy show “Almost Live." This is where “Bill Nye the Science Guy®" was born. The show appeared before Saturday Night Live and later on Comedy Central, originating at KING-TV, Seattle's NBC affiliate. While working on the Science Guy show, Nye won seven national Emmy Awards for writing, performing, and producing. The show won 18 Emmys in five years. In between creating the shows, he wrote five children's books about science, including his latest title, “Bill Nye's Great Big Book of Tiny Germs." Nye is the host of three currently-running television series. “The 100 Greatest Discoveries" airs on the Science Channel. “The Eyes of Nye" airs on PBS stations across the country. Bill's latest project is hosting a show on Planet Green called “Stuff Happens." It's about environmentally responsible choices that consumers can make as they go about their day and their shopping. Also, you'll see Nye in his good-natured rivalry with his neighbor Ed Begley. They compete to see who can save the most energy and produce the smallest carbon footprint. Nye has 4,000 watts of solar power and a solar-boosted hot water system. There's also the low water use garden and underground watering system. It's fun for him; he's an engineer with an energy conservation hobby. Nye is currently the Executive Director of The Planetary Society, the world's largest space interest organization.
Marsalina: Hi Bill Nye. My name is Marsalina. This is my son Ohenu. And we have a question about your perspective on ghosts and also what do you think happens to your life energy that ceases after you die? Is it just pushing daisies? Thank you.
Bill Nye: Marsha. Greetings. People have wondered about life after death since there have been people. It goes way, way back. We started with ghosts. I’ll tell you I don’t think there’s any such thing. I don’t think there’s anything to be afraid of when it comes to ghosts. I’m a member of both the skeptics and the counsel for scientific inquiry and we have looked and looked for haunted houses, for ghosts in cemeteries, for psychics who believe they’re in touch with people who are dead. And there’s absolutely no credible evidence. There’s no reason to believe that there are ghosts or life after death. People have tried and tried. And you may know that Houdini the famous magician said if anybody can come back from the dead it’s me man. I’m coming. And he never got in touch with anyone. No one ever heard from him. He had a secret word between he and his mother that he said I’ll give you the secret word when I come back. And do you know what the secret word is? Nobody knows, it was secret and he never came back.
But what happens to humans our brains are so active. We imagine so many things and we’re always looking for cause and effect. That is to say when you hear a bump in the night you want to know what caused it. You want to know what brought it on. And the first thing you might imagine is that there’s somebody or some entity out there causing this effect, the bump but you can’t see it. So then we intuitively or instinctively for ancient reasons put a pattern on it. We imagine it has an agent as we call it but there’s something out there, some agent is causing this. But it could be the wind blew and knocked the candle over and there’s no ghost and just get over it. Don’t be afraid of that. Now when it comes to life after death I’ve thought about this quite a bit and what happens, what are you like when you’re dead? If you watch people age like my grandmother, my beloved grandmother. She was so smart when I was a little kid. She collected wildflowers. She was very skilled as an artist. She could draw landscapes and she was like a naturalist.
Traditionally she would draw detailed pictures of flowers depicting their very detailed parts, petals, stamen, pistols and so on. But as she got older she got dementia. She could not remember things. She didn’t recognize me. And so she eventually died of old age. And I just don’t see any evidence that she would suddenly be a young person as an after dead ghost entity. It looks like to me this life is all you get. This is it. There’s nothing afterwards. So what you’ve got to do is live this life as best you can. That’s the way to go. And if it does turn out there’s an afterlife and we all turn young again and can play rugby or whatever it is we want to do so much the better. But I see no evidence for it. And for your son there are no ghosts, sorry. And your friends who believe in ghosts you can outwit them. You’ll be ahead of them because you will not waste energy running around looking for ghosts. Instead you’ll close the window to keep the candle from blowing over or whatever made your friend believe in a ghost. Carry on. I’m sorry but it seems to be apparently this is all you get.
Bill Nye tackles the big question, a little apologetically it seems. As much as Nye would probably like to believe in heaven, messages from the ghosts of your loved ones, and an afterlife where you return to your peak and share eternity with your favorite people, he is bound by truth and science, and admits that there has been no evidence for it.
Ghosts and supernatural occurrences usually have explanations in science. A candle that blows out spookily may logically be due to a draft of wind. A feeling of being unsettled and on edge can be due to infrasound – sound at levels so low that humans can’t hear it but whose vibrations cause distinct physiological discomfort. There's also the fact that many of us want to believe in supernatural dimensions, so we create symbols and meaning where there isn't any.
Nye cites the famous magician Harry Houdini, who said if anyone could come back from the dead in ghost form, it was him. But, he never got in touch. He had the determination, but if the laws of nature don't provide an option, it may simply not be possible to come back. It’s not quite evidence against ghosts and the afterlife, but Houdini seemed pretty intent on it, so it’s something of a nail in the coffin of ghost theory.
It might seem like grim news that Nye is delivering, but the upside is that you can pour all your energy, creativity, and love into the life you’re living now. There’s no need to save anything in your reserve engines for the afterlife. Nye advises that you live the best life you can while you’re conscious – do as much good, travel all you can, learn and make those around you happy. If our human life span is all we have, it makes living even more precious and more of a gift than ever before.
Bill Nye's most recent book is Unstoppable: Harnessing Science to Change the World.

The three galaxy clusters imaged for the study
Mapping dark matter<span style="display:block;position:relative;padding-top:56.25%;" class="rm-shortcode" data-rm-shortcode-id="d904b585c806752f261e1215014691a6"><iframe type="lazy-iframe" data-runner-src="https://www.youtube.com/embed/fO0jO_a9uLA?rel=0" width="100%" height="auto" frameborder="0" scrolling="no" style="position:absolute;top:0;left:0;width:100%;height:100%;"></iframe></span><p>The assumption has been that the greater the lensing effect, the higher the concentration of dark matter.</p><p>As scientists analyzed the clusters' large-scale lensing — the massive arc and elongation visual effects produced by dark matter — they noticed areas of smaller-scale lensing within that larger distortion. The scientists interpret these as concentrations of dark matter within individual galaxies inside the clusters.</p><p>The researchers used spectrographic data from the VLT to determine the mass of these smaller lenses. <a href="https://www.oas.inaf.it/en/user/pietro.bergamini/" target="_blank" rel="noopener noreferrer">Pietro Bergamini</a> of the INAF-Observatory of Astrophysics and Space Science in Bologna, Italy explains, "The speed of the stars gave us an estimate of each individual galaxy's mass, including the amount of dark matter." The leader of the spectrographic aspect of the study was <a href="http://docente.unife.it/docenti-en/piero.rosati1/curriculum?set_language=en" target="_blank">Piero Rosati</a> of the Università degli Studi di Ferrara, Italy who recalls, "the data from Hubble and the VLT provided excellent synergy. We were able to associate the galaxies with each cluster and estimate their distances." </p><p>This work allowed the team to develop a thoroughly calibrated, high-resolution map of dark matter concentrations throughout the three clusters.</p>
But the models say...<p>However, when the researchers compared their map to the concentrations of dark matter computer models predicted for galaxies bearing the same general characteristics, something was <em>way</em> off. Some small-scale areas of the map had 10 times the amount of lensing — and presumably 10 times the amount of dark matter — than the model predicted.</p><p>"The results of these analyses further demonstrate how observations and numerical simulations go hand in hand," notes one team member, <a href="https://nena12276.wixsite.com/elenarasia" target="_blank">Elena Rasia</a> of the INAF-Astronomical Observatory of Trieste, Italy. Another, <a href="http://adlibitum.oats.inaf.it/borgani/" target="_blank" rel="noopener noreferrer">Stefano Borgani</a> of the Università degli Studi di Trieste, Italy, adds that "with advanced cosmological simulations, we can match the quality of observations analyzed in our paper, permitting detailed comparisons like never before."</p><p>"We have done a lot of testing of the data in this study," Meneghetti says, "and we are sure that this mismatch indicates that some physical ingredient is missing either from the simulations or from our understanding of the nature of dark matter." <a href="https://physics.yale.edu/people/priyamvada-natarajan" target="_blank">Priyamvada Natarajan</a> of Yale University in Connecticut agrees: "There's a feature of the real Universe that we are simply not capturing in our current theoretical models."</p><p>Given that any theory in science lasts only until a better one comes along, Natarajan views the discrepancy as an opportunity, saying, "this could signal a gap in our current understanding of the nature of dark matter and its properties, as these exquisite data have permitted us to probe the detailed distribution of dark matter on the smallest scales."</p><p>At this point, it's unclear exactly what the conflict signifies. Do these smaller areas have unexpectedly high concentrations of dark matter? Or can dark matter, under certain currently unknown conditions, produce a tenfold increase in lensing beyond what we've been expecting, breaking the assumption that more lensing means more dark matter?</p><p>Obviously, the scientific community has barely begun to understand this mystery.</p>
Scientists have found evidence of hot springs near sites where ancient hominids settled, long before the control of fire.
Astronomers spot an object heading into Earth orbit.
Minimoons<p>Scientists have confirmed just two prior minimoons. One was <a href="https://en.wikipedia.org/wiki/2006_RH120" target="_blank">2006 RH120</a>, which orbited us from September 2006 to June 2007. The other was <a href="https://en.wikipedia.org/wiki/2020_CD3" target="_blank">2020 CD3</a>, which got stuck in the 2015–2016 timeframe, and is believed to gotten away in May 2020.</p><p>2020 SO, the new kid on the block, is expected to arrive in October 2020 and pop out of orbit in May 2021.</p><div id="37962" class="rm-shortcode" data-rm-shortcode-id="f4c0fc8a2cba6536ea4cd960ebed3e6e"><blockquote class="twitter-tweet twitter-custom-tweet" data-twitter-tweet-id="1307729521869611008" data-partner="rebelmouse"><div style="margin:1em 0">Asteroid 2020 SO may get captured by Earth from Oct 2020 - May 2021.

Identifying 2020 SO<p>The first clue 2020 SO isn't your ordinary asteroid is its exceptionally low velocity. It's traveling much more slowly that a typical asteroid — their <a href="https://www.lpi.usra.edu/exploration/training/illustrations/craterMechanics/" target="_blank">average rate of travel</a> <a href="https://www.lpi.usra.edu/exploration/training/illustrations/craterMechanics/" target="_blank" rel="noopener noreferrer"></a>is 18 kilometers (58,000 feet) per second. Even <a href="https://en.wikipedia.org/wiki/Moon_rock" target="_blank">moon rocks</a> sent careening into Earth orbit by impacts on the lunar surface outpace pokey 2020 SO.</p><p>For another thing, 2020 SO has an orbital path very similar to Earth's, lasting about one Earth year. It's also just slightly less circular than our own orbit, from which it's barely tilted off-axis.</p><p>So, what is it? <a href="https://cneos.jpl.nasa.gov/ca/" target="_blank">NASA estimates</a> that the object has dimensions very reminiscent of a discarded Centaur rocket stage from the <a href="https://en.wikipedia.org/wiki/Surveyor_2" target="_blank" rel="noopener noreferrer">Surveyor 2 mission</a> that landed an unmanned craft on the moon. Back in the day, rocket stages were jettisoned as craft were aimed toward their desired position. This stuff, if released high enough, remains in space. It appears that this Centaur rocket, launched in September 1966, is now making its way back homeward, at least for a little bit.</p><p>When 2020 SO arrives at its closest point in December, the rocket is expected to be about 50,000 kilometers from Earth. Its next closest approach is much further: 220,000 kilometers, in February 2010.</p><img type="lazy-image" data-runner-src="https://assets.rebelmouse.io/eyJhbGciOiJIUzI1NiIsInR5cCI6IkpXVCJ9.eyJpbWFnZSI6Imh0dHBzOi8vYXNzZXRzLnJibC5tcy8yNDQzMDk3NC9vcmlnaW4uanBnIiwiZXhwaXJlc19hdCI6MTYyODg1MTQ1MX0.HGknDwqp0GmeuczKY_AS7vrPG7KMFUc_XO95tNoI2xo/img.jpg?width=980" id="e5cda" class="rm-shortcode" data-rm-shortcode-id="85eb1f790d8c3ee5b261f7ba13eaa5e1" data-rm-shortcode-name="rebelmouse-image" alt="Centaur rocket stage" />

What we may be able to learn<p>Earthly space programs being as young as they are, scientists would love to know what's happened to our rocket during a half century in space.</p><p>While 2020 SO won't get close enough to drop into our atmosphere, its slow progress has scientists hopeful that they'll still get some kind of a decent look at it.</p><p>Spectroscopy may be able to reveal what the rocket's surface is like now — has any of its paint survived, for example? Of course, being out in space, it's likely to have been hit by lots of dust and micrometeorites, so the current state of its surfaces is also of interest. Experts are curious to know how reflective the rocket is at this point, valuable information that can help planners of future long-term missions anticipate how well a craft out in space for extended periods will remain able to reflect sunlight.</p>
