    discuss the energy potential of converting sewage treatment plants into self-sustaining facilities. The plants would get their power from the sewage they treat.

     Maybe this would of been a better OP title for the original thread.

    Did you really think you were going to get an intelligent discussion with flammable farts in the title? 

  2. The NASA/ESA Hubble Space Telescope has captured the closest images yet of the sky’s latest visitor to make the headlines, comet C/2020 F3 NEOWISE, after it passed by the Sun. The two images in this video were take three hours apart on 8 August 2020 and features the comet’s prominent jets that are emerging from the nucleus. Credit: NASA, ESA, Q.

  3. How about the language with the longest word/name?

    Titin 

    Quote

    The name titin is derived from the Greek Titan (a giant deity, anything of great size).[17]

    As the largest known protein, titin also has the longest IUPAC name of a protein. The full chemical name of the human canonical form of titin, which starts methionyl... and ends ...isoleucine, contains 189,819 letters and is sometimes stated to be the longest word in the English language, or of any language.[59] However, lexicographers regard generic names of chemical compounds as verbal formulae rather than English words.[60]

    just a small section.

  4. It's effective, but it seems to be limited due to the side effects. I can definitely see this being used more and more in the future.

    Studies have found that exposure to high intensity ultrasound at frequencies from 700 kHz to 3.6 MHz can cause lung and intestinal damage in mice. Heart rate patterns following vibroacoustic stimulation has resulted in serious negative consequences such as atrial flutter and bradycardia.[13][14]

    Wouldn't like to be on the receiving end of this one.

    The possibility of a device that produces frequency that causes vibration of the eyeballs—and therefore distortion of vision—was suggested by paranormal researcher Vic Tandy[1][2] in the 1990s

    What about Nerf guns?

    As for "Dark Matter",  is there really such a thing.  There's no evidence for it.

    Quote

    Dark matter and normal matter have been wrenched apart by the tremendous collision of two large clusters of galaxies. The discovery, using NASA's Chandra X-ray Observatory and other telescopes, gives direct evidence for the existence of dark matter.

    In the center of our galaxy, hundreds of stars closely orbit a supermassive black hole. Most of these stars have large enough orbits that their motion is described by Newtonian gravity and Kepler's laws of motion. But a few orbit so closely that their orbits can only be accurately described by Einstein's theory of general relativity. The star with the smallest orbit is known as S62. Its closest approach to the black hole has it moving more than 8% of light speed.

    What chemical gives farts their distinctive smell? I highly doubt that if I bought canisters of pure nitrogen, hydrogen, carbon dioxide, oxygen, and methane, and then mixed them in the proportions you listed the mixture would have smell I would expect a fart to have. What chemical(s) make the smell?

    Ok this is pretty gross, and don't quote me on this, but isn't the smell due to small molecules of actual poo getting stuck up your nose?

    Heard that 'fact' a few times now.

    Keep in mind that if artificial gestation pods are developed, and if they become cheap, reliable and widely available, then very few women would be willing to go through the stress of natural childbirth and would instead opt to use the "pods".

    Disagree. If this was true, most women would only have one child, which isn't the case. 

    Question: does/would using a gestation pod lesson the bond between mother and child?

    and children would probably instead be raised by the community or the state.

    Let's hope not. They already do, with mixed results. Just go to your local prison if you want to speak to some of them.

    Comet C/2020 F3 (NEOWISE) isn’t what astronomers call a great comet. But it’s a wonderful binocular comet that began gracing our early morning skies in early July. Now it’s visible in the evening, as soon as the sky gets really dark. We’ve been hearing from people throughout the Northern Hemisphere who’ve seen this comet, and we’ve heard from a few who have spotted it from Southern Hemisphere locations.

    Location of Comet NEOWISE from July 27 to August 2, 2020. Facing west-northwest shortly after dusk, as seen from the U.S. See how the curve in the Big Dipper’s handle points to the bright star Arcturus? For a specific view – shortly after your local dusk – from your specific location on the globe, try Stellarium. Illustration by Eddie Irizarry using Stellarium.

    The star TYC 8998-760-1 (top center) was photographed with two giant exoplanets (arrows), the first time astronomers have directly imaged more than one planet orbiting a sunlike star. The bright spots above star TYC 8998-760-1 are other stars in the background. BOHN ET AL/ESO

    Quote

    For the first time, an exoplanet family around a sunlike star has had its portrait taken. Astronomers used the Very Large Telescope in Chile to snap a photo of two giant planets orbiting a young star with about the same mass as the sun, researchers report July 22 in The Astrophysical Journal Letters.

    A 35-mile-long rift opened up in the Ethiopian desert in 2005, the result of tectonic plates slowly spreading the continent apart.

    Quote

    This desolate expanse sits atop the juncture of three tectonic plates that are very slowly peeling away from each other, a complex geological process that scientists say will eventually cleave Africa in two and create a new ocean basin millions of years from now. For now, the most obvious evidence is a 35-mile-long crack in the Ethiopian desert.

    Hello.I am a aspiring engineer or physicist or computer scientist.While in high school(8th grade I am 13) I have had multiple chats with individuals about the topic of FUTURE LIKE SPACE TRAVEL.I don't mean flying saucers but spacecrafts that use magnetic levitation to leave earth's atmosphere , or Negative mass built spacecraft .I was wondering what are the possibilites of such technologies. 

    Unlikely, as Swansont says, but it doesn't mean people don't come up with ideas. Try these if your interested.

    Will the natural course of evolution without human agency cause the dinosaurs or something like them to evolve again in the far future?

    They already did, dinosaurs are just animals.

    Nuclear weapons designer Ted Taylor has alleged that a 105 mm (4.1 inch) diameter shell with a mass of 19 kg is theoretically possible.[3] Conversely, reduction beyond the size of the W54 means that linear implosion designs must be employed and neutron reflectors dispensed with ("bare core"), so a much larger mass of fissile material is required and explosive yield is reduced dramatically.

    Special Atomic Demolition Mines (SADMs) were developed for employment by Soviet special operations forces, known as Spetsnaz. While the numbers of SADMs developed for possible use by Soviet forces was unclear, former Red Army intelligence personnel have written that these weapons were designed to have between a 0.8 and 2.0 kiloton yield, and were man-portable. Research suggested that the Soviets investigated applying "boosted fission" technology to their SADMs, which would provide 98% of the yield of fusion weapons.

    Spectacular 3D maps of the universe have revealed one of the biggest cosmic structures ever found — an almost-inconceivable wall stretching 1.4 billion light-years across that contains hundreds of thousands of galaxies.

    Effective July 6, 2021, the United States will no longer be a member nation of the World Health Organization, the White House announced Tuesday, ending the U.S.’s involvement in the global group, which President Donald Trump has claimed conspired with China to hide the true extent of the coronavirus pandemic.

    A newly discovered four-quark particle (illustrated) is the first to contain all heavy quarks, and more than two quarks of the same kind. CERN

    Quote

    Physicists think they have detected the first conglomerate of four quarks incorporating more than two of the same kind. This tetraquark contains four quarks of the charm variety: two charm quarks and their antimatter counterparts, called anticharm quarks, researchers report online at arXiv.org on June 30.
