Is our universe the ultimate computer? Scientist says we're living in a simulation
A physicist has claimed that the science-fiction film, The Matrix may hold more truths than people first though and has pointed to gravity has a sign that we are living in a virtual simulation.
In his new paper Melvin Vopson, an associate professor in physics at the University of Portsmouth, said our universe is the 'ultimate computer.'
Gravity's pull – both on planet Earth and in outer space – is the universe trying to keep its vast amount of data organised, Vopson claims.
Vopson adds that forcing objects with mass into one direction – for example downwards towards Earth's core – is similar to how computers compress code.
The scientist said: 'The universe evolves in a way that the information content in it is compressed, optimized and organized – just as computers and computer code do.
'Hence, gravity appears to be another process of data compression in a possibly simulated universe.'
The simulation theory is not unique to Professor Vopson and is popular among a number of well-known figures including Elon Musk.
However, in recent years Vopson has been investigating the various cues that suggest we live in a simulated reality.
His new study, published in AIP Advances, reports that gravity may be one of these everyday clues and 'evidence of a computational universe'.
Gravitational attraction helps to reduce 'information entropy' – which is essentially how much information there is in an object in a given space.
The study introduces a new way to think about gravity – not just as a pull, but as something that happens when the universe is trying to stay organised.
Vopson said: 'My findings in this study fit with the thought that the universe might work like a giant computer, or our reality is a simulated construct.'
The scientist stresses that he's not only talking about the gravitational pull we see on Earth and the 'apple falling on Isaac Newton's head' moment four centuries ago.
But is instead speaking much more widely, gravity is a fundamental force throughout our vast universe, which is commonly said to be 93billion light-years across.
In space, gravity has many roles including building entire galaxies, pulling planets into orbit around their stars, and influencing the motion of nearby objects.
So, in space, matter and objects may be being pulled together because the universe is trying to keep information tidy and compressed.
Vopson said: 'To put it simply, it is easier to compute all the properties and characteristics of a single object in space, rather than multiple objects.
'That is why objects in space are pulled together.'
The physicist is known for formulating the principle that information is not just an abstract mathematical entity, but a 'physical, dominant, fifth state of matter'.
He argues that information has mass and that all elementary particles – the smallest known building blocks of the universe – store information about themselves, similar to the way cells have DNA.
He thinks bits – the unit of digital information – have their own mass and energy, which has wide-ranging implications for computing technologies, physics and cosmology.
In a previous paper, Vopson established a new law of physics, called the 'second law of information dynamics' to explain how information behaves.
His law establishes that the 'entropy', or disorder, in a system of information decreases rather than increases.
This new law came as somewhat of a surprise, because it is the opposite of the second law of thermodynamics, established in the 1850s, which explains why we cannot unscramble an egg or why a glass cannot unbreak itself.
As it turns out, the second law of infodynamics explains the behaviour of information in a way that the old law cannot.
Vopson said; 'The second law of infodynamics requires the minimisation of the information content associated with any event or process in the universe.
'To put it simply, everything appears to evolve to an equilibrium state where the information content is minimal.
'Such behaviour is fully reminiscent of the rules deployed in programming languages and computer coding.'

Study shows how horses use facial expressions to communicate
New research has shown how horses use their faces to communicate emotions - not only to each other but also with other species, like not the first time facial expressions in horses have been studied but researchers from the University of Portsmouth looked at horses in situations that were natural, rather than created by humans like in previous made a list of 805 different facial displays across 22 behaviours. Dr Leanne Proops from the university said the research "opens up new possibilities for understanding equine emotions and improving welfare." The study shows horses use different facials cues in different is shown by flattening the ears which face backwards, the inner brow rises, nostrils will flare and they will lower their a horse is alert or curious their ears will face forwards and slightly inwards and they will blink more they're being friendly, horses are usually neutral which means there's no obvious facial expression to show this emotion.A playful horse will show lots of facial movements including a raised chin, parted lips, open mouths and rotated flattened Proops said the research is a "game-changer for anyone working with horses". She said: "It gives us a new lens through which to view and interpret their behaviour, ultimately leading to better care and stronger human-animal relationships."

Portsmouth uni and GB Row Challenge research finds UK seas are warming
Data, collected by rowers who circumnavigated Great Britain and analysed by university researchers, has found that sea temperatures have risen.A report by the University of Portsmouth and GB Row Challenge found UK seas were, on average, 0.39C (32.7F) warmer in 2023 compared to data was collected by a crew who took part in the 2023 GB Row Challenge which saw participants travel more than 2000 miles (3219 km) around of environmental pollution at the University of Portsmouth, Fay Couceiro, said: "We expect fluctuations but we don't want to see this increasing number of marine heatwaves." Some regions, including the Celtic and Irish Seas and the northern North Sea, experienced temperature increases exceeding 2C (35.6F), during a marine said the data gives an important indication of the health of our oceans."Understanding it allows us to better protect the species that are there," she added that sessile organisms like mussels and oysters, which are unable to move themselves to cooler waters. were most affected by the rising temperatures. Environmental DNA, underwater sound and microplastic data was also collected by the the surprising findings was a fragment of Bakelite plastic found in Clacton-on-Sea north of the Thames was the first commercially produced synthetic plastic, which was widely used in the early 1900s and largely discontinued in the 1940s."Despite being phased out of production decades ago, this possible century-old relic has persisted, highlighting how plastics can linger in ecosystems for generations," Ms Couceiro said."This longevity contributes to the accumulation of microplastics, which infiltrate our soils, waterways, and even the food chain, posing risks to both environmental and human health. The finding serves as a reminder of the urgent need for sustainable materials and robust waste management practices to address the escalating global plastic crisis." 'Citizen science' Team Ithaca, an all-female rowing crew, were responsible for gathering the group also went on to become the fastest female team to row around Great Row Challenge founder, William de Laszlo said: "Team Ithaca's expedition highlights the potential of citizen science in contributing to environmental research."Their dedication and resilience have not only set a new benchmark in ocean rowing but have also provided critical insights into the challenges facing Britain's coastal waters."

Chernobyl farmland found fit for farming decades after nuclear disaster
Ukrainian farmland abandoned after the 1986 Chernobyl nuclear disaster is again fit for agriculture, a new study reveals. In the aftermath of the nuclear accident, vast swathes of northern Ukraine were designated as too hazardous for farming. The Chernobyl Exclusion Zone of 4,200sqkm around the nuclear plant remains uninhabited to this day and is now one of Europe's largest nature reserves. But the 2,000sqkm Zone of Obligatory Resettlement, never fully abandoned, is home to thousands of people. In the years since the disaster, radiation levels in the region have declined significantly due to radioactive decay and erosion of surface soils. Yet, there has been no re-classification of the abandoned lands since zoning criteria were put in place in 1991. In recent years, some farmers in the region have taken matters into their own hands and started sparse agricultural production. Now, a new study published in the Journal of Environmental Radioactivity, confirms that crops can be grown safely on most of the land. Researchers assessed around 100 hectares of land in the Zhytomyr region for contamination levels and predicted the uptake of radioactive substances by common crops such as potatoes, cereals, maize, and sunflower. By analysing soil samples and measuring external gamma radiation, they confirmed that the effective radiation dose to agricultural workers was well below Ukraine's national safety threshold. The researchers found that the radiation amount was significantly lower than background radiation levels experienced naturally all over the world. This means that, with proper monitoring and adherence to Ukrainian food safety regulations, many crops can safely be grown in these previously restricted zones. 'Since 1986, there has been a lot of misinformation about radiation risks from Chernobyl, which has negatively impacted on people still living in abandoned areas,' study lead author Jim Smith from the University of Portsmouth said. 'This research is important for communities affected by the Chernobyl disaster.' The new study outlines a scientific approach to assess and bring valuable farmland back into production. 'This isn't just about Chernobyl. It is about applying science and evidence to ensure people are protected, while making sure land isn't needlessly left to waste,' Dr Smith said. 'The methods developed here could be applied to other radioactively contaminated sites worldwide.'
