In Einstein's theory of general relativity, gravity is always attractive. But according to a new paper, quantum mechanics offers a loophole that can create antigravity. And not only this, if it was measurable that would prove that gravity has quantum properties. How does this work and how can repulsive gravity be compatible with the laws of physics that we know and like? Let's take a look.

In this episode, David Ariosto speaks with SpinLaunch CEO Massi Ladovaz. They discuss what attracted Ladovaz to reimagining how to launch spacecraft, the changing needs and challenges of building constellations […]

For over half a century, people taking the psychedelic drug DMT have reported meeting alien beings. Now a scientist says these aliens might be real, and that he has the mathematics to prove it. Forget string theory and extra dimensions; here come aliens and psychedelics. Let's take a look.

About 25 years ago, astrophysicists noticed that the universe’s expansion is accelerating. To account for this observation, physicists came up with a new type of energy – called dark energy – which supposedly makes up more than 75% of the universe, and also has negative pressure. In a new paper, mathematicians claim that dark energy isn’t needed to explain that accelerating expansion, and

The electric car revolution was supposed to be inevitable. But over the past six months it's begun to look shaky. The clearest warning sign isn't sales figures, it's what carmakers are doing with their own money: writing off huge losses, scaling back their plans, and cancelling battery projects. So what's really happening to electric car demand, and is the slowdown temporary? Let's take a look.

You might think that black holes suck in light without letting it escape, but they actually concentrate light in the photon sphere which surrounds their horizon. In a recent paper, researchers created a new type of laser which concentrates light using a technique similar to those found in the photon sphere. Let’s take a look.

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. If you could copy quantum states without harming the original, much of the error-correcting complications in quantum computing could be avoided. Luckily, in a recent paper, physicists have demonstrated that there’s a way around the “

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. Let’s have a look.

Physicists have been arguing about dark matter for almost a century, and now, after all this time, their most favourite evidence for dark matter – the Bullet Cluster – disappeared. This isn’t just an interesting development from a scientific perspective, it is also a good illustration for what is going wrong in this research area. I have a brief summary.

Quantum computing is supposed to be one of the most exciting new technologies that humanity is working on, with companies promising it can be used in chemistry, material science, logistics, and finance. Over the years, those use cases have been slowly eroded, but investment in quantum tech has only increased. Why? Let’s take a look.

Since the early days of quantum physics, some scientists have believed that there’s a link between quantum mechanics and consciousness. While most researchers don’t think this idea holds water, a few have published papers about how phosphate molecules in the brain could link consciousness to quantum physics. Let’s take a look.

In 2011, three physicists won the Nobel Prize for showing that the expansion of the universe speeds up, which is usually attributed to aa mysterious type of energy called “dark energy”. But last year, though, a different group published research showing that universal expansion isn’t actually getting faster. Since then, the two groups have engaged in a whole bunch of back-and-forth refuting each

It was touch-and-go after that season 5 finale, but Clarkson's Farm season 6 will be returning. Here's everything we know about its release window, plot, and more.

If you haven't streamed Clarkson's Farm season 5 episodes 7 and 8 yet, do so at your own risk — as fans are still reeling after one 'brutal to watch' event after another.
