In space, discoveries continue to be made that challenge scientific beliefs, as distant objects reveal the solar system is much bigger than first thought and the observation was previously made that a part of the sun is broken. Now, there is evidence to suggest the existence of a ninth undiscovered planet that is at the very edge of the solar system and could point towards evidence that our understanding of gravity is wrong. The discovery was made by two scientists who studied the effects that the Milky Way galaxy had on objects in the solar system’s outer edge. Galaxies are able to rotate extremely fast without any of their contents escaping, and most experts believe that the existence of dark matter might explain why. Dark matter is invisible and does not emit, nor reflect light, and it is hypothesized that galaxies are surrounded by dark matter rings that bind the galaxies together in their own gravitation pull and stop them from emitting material. But now, the gravitational theory of Modified Newtonian Dynamics (MOND) may suggest that dark matter is not why galaxies stay intact despite staggering rotational speeds. Instead, some believe that under the rotational velocities experienced by galaxies, a new kind of gravitational behaviour occurs. Case Western Reverse scientist Harsh Mathur, explained: “MOND is really good at explaining galactic-scale observations, but I hadn’t expected that it would have noticeable effects on the outer solar system.” Planet 9 comes into play because objects in the Kuiper belt (the disk that surrounds the outer edges of the solar system) were observed clustering and exhibiting orbital anomalies that do not occur with other objects in the belt. Experts believe this may be due to the presence of an undiscovered ninth planet, as this is a phenomenon that occurred before with the discovery of new planets as their gravitation pull attracts other solar system objects. Katherine Brown, Hamilton College professor of physics, said: “We wanted to see if the data that support the Planet Nine hypothesis would effectively rule out MOND.” Their study revealed that the hypothesis could be correct and could point towards the existence of Planet 9, but they urged that their dataset was very small, so no definitive conclusions could be made. Brown explained: “Regardless of the outcome, this work highlights the potential for the outer solar system to serve as a laboratory for testing gravity and studying fundamental problems of physics.” Sign up to our free Indy100 weekly newsletter Have your say in our news democracy.

People are getting less happy with their cars – and it appears to be the fault of new technology and design innovations, according to landmark research. Customer satisfaction is falling with people pointing to a range of issues including the exterior design of the car. But particular frustration is with infotainment systems, with people turning away from them as ways of listening to music and get around. Only 56 per cent of car owners prefer to use their car’s in-built system to play audio, for instance, down from 70 per cent in 2020. Less than half of car owners prefer to use integrated systems for functions like phone calls, voice recognition and navigation. Instead, users are presumably using external systems such as their phones. In recent years, technologies such as Apple CarPlay and Android Auto have made it possible to mirror those screens, rather than use the built-in and often complicated software provided by car manufacturers. That is according to the US Automotive Performance, Execution and Layout (APEAL) study, run by JD Power. It is the first time in the 28 year history of the study that customer satisfaction has fallen two years in a row – and could point to a range of issues in the car market. Satisfaction is counted on a 1000-point scale. This year, it was measured at 845, which was down two points from last year, and three points from the year before. “The decline in consecutive years might look small, but it’s an indicator that larger issues may lie under the surface,” said Frank Hanley, senior director of auto benchmarking at JD Power, in a statement. “Despite the technology and design innovations that manufacturers put into new vehicles, owners are lukewarm about them. While innovations like charging pads, vehicle apps and advanced audio features should enhance an owner’s experience, this is not the case when problems are experienced. “This downward trajectory of satisfaction should be a warning sign to manufacturers that they need to better understand what owners really want in their new vehicles.” The survey also found a decline in satisfaction with some tech focused car companies. Tesla remains one of the higher performing brands but saw its score at 878, down nine points from last year, when the company was first included in the study. The study was based on almost 85,000 owners of new cars who were surveyed after owning the vehicle for 90 days. It ran between February and May of this year.
