A time crystal is a unique phase of matter that flips between two states with no energy input necessary – first proposed in 2012, this type of matter has now been created inside a quantum computer built by Google. The discovery is one of the first real-world problems solved by a quantum computer, and could also be harnessed to improve them.
Like a shaggy dog in springtime, some black holes have to shed. New computer simulations reveal how black holes might discard their magnetic fields.
Unlike dogs with their varied fur coats, isolated black holes are mostly identical. They are characterized by only their mass, spin and electric charge. According to a rule known as the no-hair theorem, any other distinguishing characteristics, or “hair,” are quickly cast off. That includes magnetic fields.
The rule applies to black holes in a vacuum, where magnetic fields can simply slip away. But, says astrophysicist Ashley Bransgrove of Columbia University, “what we were thinking about is what happens in a more realistic scenario.” A magnetized black hole would typically be surrounded by electrically charged matter called plasma, and scientists didn’t know how — or even if — such black holes would undergo hair loss.
Tesla Cybertruck pre-orders have exceeded 1.25 million according to unofficial data coming from a fan-sourced online reservation tracker.
Is there ever really a good time to launch a startup?
That’s the question Javier Luraschi was asking and sort of answering for himself in discussing his effort to “democratize artificial intelligence” through his new company called Hal9.
And while getting a startup off the ground is challenging enough under normal circumstances, Luraschi made his move during the COVID-19 pandemic and while suffering the effects of and searching for answers to long COVID, a condition in which people experience symptoms of the illness for extended periods of time.
The scientists found evidence that “beauty” quarks do not decay in the way they should following the Standard Model.
Beauty quarks, particles similar to but heavier than electrons, interact with all forces in the same way, so they should decay into muons and electrons at the same rate.
However, the data collected by the LHCb seems to show that these quarks are decaying into muons less often than they decay into electrons, which should only be possible if unknown particles are interfering and making them more likely to decay into electrons.
The hacker group posted proof of the breach at University Medical Center by sharing images of people’s drivers licenses and more. In other news, a new report says Georgia skipped infection-control inspections of hospitals during the pandemic.
The two airlines aim to be at the forefront of a burgeoning industry but the greatest hurdle might be getting travelers to fly on the new aircraft.
