Scientists Used IBM’s Quantum Computer to Reverse Time, Possibly Breaking a Law of Physics

 

 

 

 

 

 

The universe is getting messy. Like a glass shattering to pieces or a single wave crashing onto the shore, the universe’s messiness can only move in one direction – toward more chaos and disorder. But scientists think that, at least for a single electron or the simplest quantum computer, they may be able to turn back time, and restore order to chaos. This doesn’t mean we’ll be visiting with dinosaurs or Napoleon any time soon, but for physicists, the idea that time can run backward at all is still a pretty big deal.

The Health Benefits of Play Time

 

 

 

 

 

If you’re like most, you’re probably not in the habit of scheduling play time, and if you have kids, they’re probably not spending much time playing outdoors with their friends. After watching the DW documentary, “The Power of Play,” you may reconsider these choices. As noted in the video, humans, like most other animals, have a natural play instinct, and this instinct has important benefits.

Normally, the universe’s trend toward disorder is a fundamental law: the second law of thermodynamics.
