Cold Fusion Experiment Maybe Holds Promise … Possibly … Hang on a Sec ….

24 May 2013, 20:57 UTC Cold fusion has been called one of the greatest scientific breakthroughs that might likely never happen. On the surface, it seems simple – a room-temperature reaction occurring under normal pressure. But it is a nuclear reaction, and figuring it out and getting it to work has not been simple, and any success in this area [...] Two images from the test of a E-Cat deviceperformed on Nov. 20th 2012. Credit: Levi, Foschi et al. Cold fusion has been called one of the greatest scientific breakthroughs that might likely never happen. On the surface, it seems simple – a room-temperature reaction occurring under normal pressure. But it is a nuclear reaction, and figuring it out and getting it to work has not been simple, and any success in this area could ultimately – and seriously — change the world. Despite various claims of victory over the years since 1920, none have been able to be replicated consistently and reliably. But there’s buzz this week of a cold fusion experiment that has been replicated, twice. The tests have reportedly produced excess heat with roughly 10,000 times the energy density and 1,000 times the power density of gasoline. (...)Read the rest of Cold ...

Zany ISDC Enters Second Day

24 May 2013, 20:05 UTC Greetings from La Jolla! The International Space Development Conference is now at the lunch break of Day 2.

The International Space Development Conference is now at the lunch break of Day 2. Most people are currently at the overpriced luncheon waiting for author/scientific thinker/former Prince & Bruce Springsteen publicist Howard Bloom to speak. I skipped the lunch and had a turkey sandwich I made at my sister’s house. If the short preview Bloom gave earlier today is any indication, they’re in for quite a treat. Bloom spoke about a baby burned over 95 percent of its body American napalm. Or Vietnamese napalm. Or maybe it was Chinese or Russian napalm. Nobody really knew whose napalm it was, or whether it was napalm at all. Which made the entire tangent rather mysterious. His point — as near as I could tell — was that it was impossible to know from just the ...

3-D Ring Nebula reveals its “inner jelly doughnut”

24 May 2013, 19:14 UTC After the moon and planets, the Ring Nebula must be one of the top three deep sky objects sought out by astronomers of all stripes. Many a spring and summer night I’ve made my “pilgrimage to the Ring”. And why … Continue reading → How absolutely beautiful. This composite image of the Ring Nebula made combines views with the Hubble Space Telescope with a picture of the nebula’s outer halo from the Large Binocular Telescope (LBT) in Arizona. Click to enlarge. Credit: NASA, ESA, C. Robert O’Dell (Vanderbilt University), and David Thompson After the moon and planets, the Ring Nebula must be one of the top three deep sky objects sought out by astronomers of all stripes. Many a spring and summer night I’ve made my “pilgrimage to the Ring”. And why not? It’s easy to spot not far from the brilliant star Vega in the constellation Lyra and looks like a smoke ring frozen in time. To find the Ring Nebula, first locate Vega, the uppermost and brightest star of the Summer Triangle asterism. It’s well placed in the east at nightfall in late May. The Ring is midway between the two stars in the bottom of Lyra’s figure. ...

Hunting for Alien Megastructures

24 May 2013, 17:43 UTC It’s a big galaxy out there. Even the most skeptical scientist has to accept that if a civilisation like our own exists, then there’s a good chance we’re not the only one to have ever done so. When most people think about SETI (the search for extraterrestrial intellgence), they imagine someone like Ellie Arroway searching [...] A depiction of Larry Niven’s Ringworld. Credit: Hill/Wikimedia Commons It’s a big galaxy out there. Even the most skeptical scientist has to accept that if a civilisation like our own exists, then there’s a good chance we’re not the only one to have ever done so. When most people think about SETI (the search for extraterrestrial intellgence), they imagine someone like Ellie Arroway searching the skies for radio transmissions. But what about looking in other ways? Perhaps a highly advanced alien civilisation might build structures large enough for us to see. Vast structures, constructed on astronomical scales by advanced civilisations, is what the field of astroengineering is all about. This, admittedly, sounds audacious – and for the human race right now, it is. For us, astroengineering is still very much the realm of thought experiments, theoretical calculations, and science fiction. So it may be ...

Detection of the cosmic gamma ray horizon: Measures all the light in the universe since the Big Bang

24 May 2013, 15:34 UTC How much light has been emitted by all galaxies since the cosmos began? After all, almost every photon (particle of light) from ultraviolet to far infrared wavelengths ever radiated by all galaxies that ever existed throughout cosmic history is still speeding through the Universe today. If we could carefully measure the number and energy (wavelength) of all those photons -- not only at the present time, but also back in time -- we might learn important secrets about the nature and evolution of the Universe, including how similar or different ancient galaxies were compared to the galaxies we see today. read more
