The closest black hole that you can see it even with “naked eye” has been discovered

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.

Why our imagination for alien life is so impoverished

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.

Nick Longrich, University of Bath

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.

Utilizing Virtual Reality During Self Isolation

In the wake of the novel coronavirus, almost all of us are settling into life in quarantine.
