One of the biggest limitations of quantum quantum computing is the “no cloning” theorem, which says you cannot copy a quantum state without destroying the original. In a recent paper, physicists have demonstrated that there’s a way around the “no cloning” limitations. www.youtube.com/watch?v=gR99...

A new, computer-based calculation shows that our solar system used to have 5 or 6, rather than 4 gas giants. It seems that, billions of years ago, we lost two planets due to an instability that probably also tilted Uranus’s axis and scrambled up its moons. www.youtube.com/watch?v=XcHR...

A company claims to have developed a microchip that can extract "unlimited power" from the vacuum. I've had a look www.youtube.com/watch?v=sEte...

In general relativity, the time an object experiences depends on its acceleration. But time in quantum physics is a universal parameter. In a new paper, physicists say they want to use a special type of clock to test that difference. Let’s take a look. www.youtube.com/watch?v=j5rw...

Several companies are working on safe nuclear reactors. I've had a look at what's behind it. www.youtube.com/watch?v=d96W...
