A dissipative time crystal is a phase of matter characterized by periodic oscillations over time, while a system is dissipating energy. In contrast with conventional time crystals, which can also occur in closed systems with no energy loss, dissipative time crystals are observed in open systems with energy freely flowing in and out of them.
A study published in Cell Reports Physical Science showcases a novel method for the recycling of unsaturated polymers such as rubber and plastics.
Spanish energy giant Iberdrola has revealed two new battery storage projects in Australia – its biggest yet in the country – that will take its total capacity to more than 1,500 gigawatt hours.
The new batteries are a 250 megawatt (MW)/ 500 megawatt hour (MWh) Gin Gin project near Bundaberg in Queensland – although its EPBC application describes it only as a 500 MW project – and the 270 MW, 1,080 MWh Kingswood project in New South Wales (NSW).
To date, Iberdrola’s non-gas firming portfolio has been on the smaller side, making up just a fraction of the company’s 2.4 GW of installed renewables in Australia.
Although many are being cancelled outright, some flights are being diverted to other airports in Sicily.
This is especially the case for flights that were already in the air when Catania airport was closed.
Don’t forget that Sicily is the biggest island in the Mediterranean. It is twice the size of Cyprus, a country in its own right, and it takes at least eight hours to drive all the way from east to west.
Made famous in 1995 by NASA’s Hubble Space Telescope, the Pillars of Creation in the heart of the Eagle Nebula have captured imaginations worldwide with their arresting, ethereal beauty.
Now, NASA has released a new 3D visualization of these towering celestial structures using data from NASA’s Hubble and James Webb space telescopes. This is the most comprehensive and detailed multiwavelength movie yet of these star-birthing clouds.
“By flying past and amongst the pillars, viewers experience their three-dimensional structure and see how they look different in the Hubble visible-light view versus the Webb infrared-light view,” explained principal visualization scientist Frank Summers of the Space Telescope Science Institute (STScI) in Baltimore, who led the movie development team for NASA’s Universe of Learning.
What would it take to set Uranus ablaze? Is it even possible to burn it in the typical sense? If anyone can figure it out, it’s the Dead Planets Society.

They say that we ultimately lose information once it enters a black hole, but is this really the case? Let’s find out on today’s video. Have you ever wondered what happens to information when it falls into a black hole? Does it get destroyed forever? Does it arrive somewhere else? Does it enter a girl’s bookcase and call it for Murf? Is there a way for it to escape? Today, we’re diving into one of the biggest mysteries in physics: the black hole information paradox. But first, why should we care? Well, in case a black hole suddenly pops up in your bedroom or office table, this paradox sits at the intersection of quantum mechanics and general relativity, the two pillars of modern physics, and solving it could unlock new understandings of the universe itself. So, let’s get started. Our journey begins with looking at the basics of black holes and the paradox that has puzzled scientists for decades.
Like any good explainer, let’s begin with the basics. What exactly is a black hole? In simple terms, a black hole is a region in space where gravity is so strong that nothing, not even light, can escape from it. No Brad, it’s not a challenge; calm down. This happens when a massive star collapses under its own gravity, compressing all its mass into an incredibly small, incredibly dense point known as a singularity. Surrounding the singularity is the event horizon, the boundary beyond which nothing can return. Think of the event horizon as the ultimate point of no return. Once you cross it, you’re inevitably pulled towards the singularity, and there’s no way back. Feel like you know well about black holes? Great. Now let’s talk about Hawking radiation. In the 1970s, Stephen Hawking proposed that black holes aren’t completely black; instead, they emit a type of radiation due to quantum effects near the event horizon. This radiation, aptly named Hawking radiation, suggests that black holes can slowly lose mass and energy over time, eventually evaporating completely. But here’s where things get tricky: Hawking radiation is thermal. By that, we don’t mean that it’s smoking or anything, but that it appears to carry no information about any of the stuff that fell into the black hole. And this brings us to the heart of our mystery: the black hole information paradox. How can the information about the material that formed the black hole and fell into it be preserved if it’s seemingly lost in the radiation? With this foundation in place, I feel that we’re now ready to explore the paradox itself and the various theories proposed to resolve it.
