Well, of course, you cannot see a black hole – but the newly discovered one has two stars orbiting it, and you can see these companion stars even with the naked eye from Earth. The triple system is named HR 6819. Named QV Tel Ab, the inner component of the system is the closest black hole to Earth.
The system appears as a variable star that is dimly visible to the naked eye.Continue reading “The closest black hole that you can see it even with “naked eye” has been discovered”
It astonishes me how much we seem to know about aliens. They build technology-driven civilisations and pilot spaceships across the galaxy. They create energy-harvesting structures around their stars. They beam interstellar greetings to us. We cannot be sure that, when our own broadcasts reach them in some future era, they will breathlessly await the arrival of the next episode of Glee – but it seems a fair bet.Continue reading “Why our imagination for alien life is so impoverished”

Will our species go extinct? The short answer is yes. The fossil record shows everything goes extinct, eventually. Almost all species that ever lived, over 99.9%, are extinct.
Some left descendants. Most – plesiosaurs, trilobites, Brontosaurus – didn’t. That’s also true of other human species. Neanderthals, Denisovans, Homo erectus all vanished, leaving just Homo sapiens. Humans are inevitably heading for extinction. The question isn’t whether we go extinct, but when.Continue reading “Will humans go extinct? For all the existential threats, we’ll likely be here for a very long time”
There are about 1.6 billion people homeless, according to global homelessness statistics. Construction technology has a chance to change that. Advancements have made it possible to create an entire home by 3D printing it. This type of home construction promises a shorter supply chain and less waste for a sustainable solution. 3D-printed homes also can be eco-friendly home alternatives. The Zebra explains how.Continue reading “3D-Printed Homes: the Eco-Friendly Home Alternative”
Whether it’s gorging on junk food, smoking cigarettes, or binge-watching Netflix in lieu of exercise, bad habits are just part of the human experience. But what is it about negative behaviors, products, and lifestyle choices that make them so attractive? And why are they so addicting?Continue reading “The Science Behind the Things That Kill Us (And How to Conquer Them)”
In the wake of the novel coronavirus, almost all of us are settling into life in quarantine. Self-isolation sounds easy enough until the rose-tinted glasses are taken off, with many of us wondering what else – after work, chores, and our favorite tv shows are over – we can do to pass the time. With remote working, homeschool, and online classes freeing up more time in the day, it’s no surprise blogs and social media are populated with listicles, tutorials, and challenges – all championing the cause of taking up a new hobby or interest. Whether it’s craving an escape, craving entertainment, or just craving good old socializing, people are now flocking to virtual reality devices to get their fix.Continue reading “Utilizing Virtual Reality During Self Isolation”
