Gustav BihlmayerPeter Grünberg Institute, Research Center Jülich, Jülich, GermanyMarch 17, 2021&Bullet; physics 14, 39Control over eddies that arise in magnet-superconductor heterostructures could result in qubits that are immune to the effects of...

The simulation hypothesis is pseudoscience

0
https://www.youtube.com/watch?v=HCSqogSPU_Q I really like the idea that we are living in a computer simulation. It gives me hope that the next level will get better. Unfortunately the idea is unscientific. But...

What happened to life on Venus?

0
https://www.youtube.com/watch?v=-xMRoICR9SE A few months ago, headlines were shouting that scientists had found signs of life on Venus. It wasn't long, however, before other scientists objected. So, exactly what they found on Venus?...

An Apex Predator or Barely Chewing?
