Leading University of Portsmouth physicist’s study indicates that gravity or gravitational force is the result of a computational process within the universe.

Gravity May Be a Clue That The Universe Is a Giant Computer
If we were living in a computer simulation, would we be able to tell we were living in a computer simulation? It’s a question that’s difficult to answer, but physicist Melvin Vopson of the University of Portsmouth in the UK believes that he may have found a clue.
According to his latest study, gravity could be a product of computational processes within the Universe, a by-product of the Universe’s attempt to keep information and matter neatly organized in space and time.
“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,” Vopson says.
Astronomers discover explosive outflow in star-forming complex using ALMA data
By analyzing the data from the Atacama Large Millimeter/submillimeter Array (ALMA), astronomers have investigated a star-forming region known as G34.26+0.15. As a result, they discovered an explosive outflow in this complex. The study was reported in a paper published on April 22 on the arXiv preprint server.
Flares from magnetized stars can forge planets’ worth of gold
Astronomers have discovered a previously unknown birthplace of some of the universe’s rarest elements: a giant flare unleashed by a supermagnetized star. The astronomers calculated that such flares could be responsible for forging up to 10% of our galaxy’s gold, platinum and other heavy elements.
The discovery also resolves a decades-long mystery concerning a bright flash of light and particles spotted by a space telescope in December 2004. The light came from a magnetar—a type of star wrapped in magnetic fields trillions of times as strong as Earth’s—that had unleashed a giant flare.
The powerful blast of radiation only lasted a few seconds, but it released more energy than the sun does in 1 million years. While the flare’s origin was quickly identified, a second, smaller signal from the star, peaking 10 minutes later, confounded scientists at the time. For 20 years, that signal went unexplained.
Sun’s explosions echo in Earth’s skies: How the atmosphere synchronizes with solar flare pulsations
Earth’s atmosphere is much more sensitive to ripples of radiation from the sun than scientists previously believed, new research by Queen’s University Belfast has found.
Solar flares, which are sudden and intense bursts of energy from the sun’s magnetic field, happen regularly.
Understanding how they impact the Earth’s atmosphere is important as very powerful flares can cause inaccuracies in GPS systems and, in extreme cases, can cause total radio blackouts, where all signal is lost.
ESA’s Biomass mission launches aboard Vega-C
The European Space Agency’s seventh Earth Explorer mission, Biomass, launched on Tuesday aboard an Arianespace Vega-C rocket. Biomass, which will study Earth’s forests and their impact on the planet’s climate, lifted off from Kourou, French Guiana, at 09:15 UTC (6:15 AM local time).
Noto quake 3D model adds dimension to understand earthquake dynamics
On New Year’s Day 2024, a massive 7.5-magnitude earthquake struck the Noto Peninsula in north central Japan, resulting in extensive damage in the region caused by uplift, when the land rises due to shifting tectonic plates. The observed uplift, however, varied significantly, with some areas experiencing as much as a 5-meter rise in the ground surface.
To better understand how the characteristics of the affected fault lines impact earthquake dynamics, researchers in Japan used recently developed simulations to make a detailed model of the fault. The findings could help develop models to simulate scenarios of different earthquakes and mitigate disasters in the future.
The results were published in the journal Earth, Planets and Space.

Earth-Like Exoplanets Are Common
A new study of light anomalies combined with results from a Korea Microlensing Telescope Network microlensing survey show that super-Earths exist as far from their host star as our gas giants are from the sun. Which means that Earth-like exoplanets are a lot more common NASA press releases over every new statistical wobble suggest.
‘Here Is The Letter That Has Destroyed My Universe’ And 4 More Astrophysics Revolutions
On this day, April 25, in 1929, the world learned how astronomer Edwin Hubble had discovered that the universe was much larger than we had believed. On this day in 2025, you can preorder a book and on the 29th learn about this and four other Astrophysics discoveries that changed how we see the universe — and ourselves — in The Story of Astrophysics in Five Revolutions.

He had published his seminal paper in the March issue of Astrophysical Journal but on April 25th in Proceedings of the National Academy of Sciences he published the how, and people began to think about what it meant. He had discovered that the collection of gas and dust we call Andromeda was actually another galaxy.
