This 420 podcast about Black Holes will blow your mind with the power of Christ

Gimlet Media's Every Little Thing podcast is based on a pretty simple concept: you call a hotline and leave a message with a question that's been bugging you. If it's intriguing enough, they make a podcast about the answer. When a guy named Kyle left a meandering voicemail about the nature of spacetime as it relates to black holes, the show's hosts couldn't resist. His giggley, midwest-by-way-of-California-surfer-dude tone seemed like the perfect stoned-at-3-am-philosophical-question fit for the...

Microsoft built a ‘Plasma Bot’ to tell you if you can donate plasma to help fight COVID-19

Plasma taken from the blood of recovered COVID-19 patients stands a real chance of being one of the more effective short-term measures feasible in the ongoing effort to control the global coronavirus pandemic. The FDA has issued a broad call for donations from eligible individuals, and now Microsoft has built an online screening tool on behalf of the CoVIg-19 Plasma Alliance (which is funded in part by the Bill and Melinda Gates Foundation). The “CoVIg-19 Plasma Bot” that Microsoft created fo...

Astronomers See Glimmers of a Second World Circling the Nearest Star to the Sun

A team of astronomers shocked the world back in 2016 when they revealed evidence of an Earth-sized exoplanet in the habitable zone of our nearest stellar neighbor, a star called Proxima Centauri. Scientists are hunting for a second planet in this system—and maybe, maybe, they’ve found something.Read more...

Untold stories of the Apollo 13 engineers

Late on 13 April 1970, the night shift had started in Houston’s Manned Spaceflight Center. Engineers tried to sift through reams of odd data coming about the Apollo 13 spacecraft, from instrument readings to the confused reports from three astronauts. It looked like they were rapidly losing their oxygen supply. “First of all, we thought we’d boil it down to something simple and obvious,” engineer Arnold Aldridge recalled later. He made a phone call to an especially insightful young engineer, Joh...

Gamma-ray space telescope study may have spotted dark matter

Analyzing data from the Fermi Gamma-ray Space Telescope, researchers find hints of dark matter.The scientists looked to spot a correlation between gravitational lensing and gamma rays. Future release of data can pinpoint whether the dark matter is really responsible for observed effects. By comparing data derived from gravitational lensing and gamma ray observations by the Fermi Gamma-ray Space Telescope, a study showed that certain regions of the sky emit more gamma rays. While the main cause...

The Fate of a Dark Matter Theory Hinges on These Unidentified X-Rays

Despite decades of searching, no one has yet cracked the mystery of dark matter. One hypothesis to explain it relies on strange x-rays emanating from distant galaxies and galaxy clusters, but a new paper appears to rule out dark matter as producing these mysterious x-rays. Read more...

Biggest explosion ever seen in the Universe

A massively powerful eruption has been detected in the Ophiuchus galaxy cluster, located about 390 million light years from Earth. It is the biggest such event ever observed. In some ways, this blast is similar to how the eruption of Mt. St. Helens in 1980 ripped off the top of the mountain,” said Simona Giacintucci of the Naval Research Laboratory in Washington, DC, and lead author of the study. “A key difference is that you could fit fifteen Milky Way galaxies in a row into the crater this eru...

Oh Yeah, Betelgeuse Is Definitely Looking Weirder

At this point, we’re all crossing our fingers that the dying star Betelgeuse will hurry up and explode already, because who doesn’t love a good show? The red giant star (visible in the constellation Orion) has been growing dimmer since late last year, leading many to speculate it could soon go supernova. Scientists…Read more...

There is no dark matter. Instead, information has mass, physicist says

Researchers have been trying for over 60 years to detect dark matter. There are many theories about it, but none are supported by evidence. The mass-energy-information equivalence principle combines several theories to offer an alternative to dark matter. None The  “discovery” of dark matter We can tell how much matter is in the universe by the motions of the stars. In the1920s, physicists attempting to do so discovered a discrepancy and concluded that there must be more matter in the univ...

#TwistedTropes 30. Halley's boring comet

Image from NASA Universe on Flickr Comets are generally quite spectacular. It's quite thrilling, but also quite rare to gaze up into the night sky and see a comet tail in the sky. Some comets are more thrilling than others, but there's one that is so boring I very nearly didn't complete this blog post, falling asleep twice during its writing (It was three times, I counted - Editor).The boring comet was discovered by Edmond Halley, a beauty contest organiser who wore nice wigs, during a ...

Mystery effect speeds up the Universe – not dark energy, says study

Astrophysicists from Russia propose a theory that says dark energy doesn't exist.Instead, the scientists think the Casimir Effect creates repulsion.This effect causes the expansion of the Universe to accelerate. None Dark energy, one of the most controversial physics ideas, is getting another challenge. After all, if this force is supposed to make up about 68% of the mass-energy of the Universe, where exactly is it? A new paper by a pair of Russian astrophysicists says dark energy simply doesn...
