Black holes are the most confusing things out there in the universe and no-one really knows what they are – at least, that’s our very basic grasp of it. Now, though, a new study has posited a theory that black holes are structures created by unseen cosmic dimensions - or topological stars. And just to make it a little more confusing, these topological stars exist purely in the hypothetical realms of mathematics. Researchers at Johns Hopkins University have been exploring string theory, which posits that particles in the universe are actually tied to extra (hidden) dimensions through vibrating strings.

The study finds that topological stars would appear “remarkably similar to black holes in apparent size and scattering properties, while being smooth and horizonless”. The study, which was published in Physical Review D, found that these stars which until now have only existed in hypothetical form, look an awful lot like the black holes out in the universe. “String theory is a theory that reconciles quantum physics and gravity into a quantum gravity theory,” study leader Pierre Heidmann said. Speaking to Motherboard, he said: “Usually when you have a new theory like that, you have new degrees of freedom that come with it, and you can try to see what new fundamental objects can arise from that.” Co-author of the study Ibrahima Bah added: “It’s an interesting question to ask: Are there things other than a black hole [that] will give you a hint about what new physics could look like?” “But before you get there, you need to know how to tell whether you have a black hole or not, and to do that you have some prototype examples of things that are not black holes to be able to compare." As ever, black holes remain the most mysterious, and the most fascinating things out there. Have your say in our news democracy.

Scientists have found a vast planet, so large that it should not exist. The planet appears to be too big for its sun, and therefore calls into question our understanding of how planets and solar systems form, according to the researchers who found it. The planet is more than 13 times as massive as Earth. It orbits around a star that is nine times less massive than our Sun. As such, the ratio between the two of them is 100 times higher than it is between the Earth and our sun. It is the first time that a planet with such a high mass has been seen orbiting a star with such a low amount of mass. And the discrepancy is so large that scientists thought such a planet could not exist. “This discovery really drives home the point of just how little we know about the universe,” said Suvrath Mahadevan, from Penn State. “We wouldn’t expect a planet this heavy around such a low-mass star to exist.” When stars are formed, out of large clouds of gas and dust, that material sticks with the star as a disc that orbits around it. Planets can then form out of that extra material, and go on to make a planetary system like our own. But science would suggest that the disc around the star in the new paper, known as LHS 3154, would not have enough material to make a planet so large. “The planet-forming disc around the low-mass star LHS 3154 is not expected to have enough solid mass to make this planet,” Mahadevan said. “But it’s out there, so now we need to reexamine our understanding of how planets and stars form.” The finding is reported in a new paper, ‘A Neptune-mass exoplanet in close orbit around a very low mass star challenges formation models’, published in Science.

Apple is rumoured to be working on a brand new type of battery for its next iPhone, potentially signalling an era-defining transition for the smartphone industry. The stacked battery design will feature on the entire lineup of iPhone 15 devices, according to anonymous leaker @RGcloudS, setting the standard for smartphone manufacturers and transforming the way people use their phones. The next-generation battery technology could result in faster charging, greater capacity and an iPhone that can run for several hours longer between charges. So how does it work and why is it so important? What is stacking technology? The word ‘stack’ refers to the configuration of the elements within a battery cell. The positive and negative electrodes within a typical battery cell are rolled up in a process known as winding, whereas stacked battery cells folds the electrodes up into layers. This makes the most of the space available within a battery cell, while also reducing resistance to lower the amount of heat generated when charging or using the battery. The design allows for a significantly higher charge capacity without changing the form of the battery, meaning no other existing components need to be altered to fit it. Why would Apple change its battery design? Lithium-ion batteries have been the standard power units in smartphones since the first iPhone was unveiled by Apple in 2007. There have been iterative upgrades to improve performance and make them more durable, though the underlying design has largely remained the same. With Apple now working on brand new devices, such as its Vision Pro headset, it makes sense for the world’s richest company to explore new battery innovations. One of the biggest criticisms of its mixed reality device was the external battery pack, so improving capacity could overcome this deficiency. Who else is working on stacked battery technology? Larger lithium-ion batteries used in electric vehicles already use stacking technology, though condensing them into a size that fits in a phone has proved tricky. Reports emerged earlier this year that Samsung, Apple’s chief smartphone rival, was working on adapting the technology to fit in its flagship Galaxy S24 Ultra phone. The inclusion of a stacked battery could allow the South Korean electronics giant to maintain the battery capacity and performance of its current S23 range, while squeezing it into a smaller form factor. This could allow for new hardware to be added, from a new camera lens, to a major upgrade to the device’s GPU.
