Every now and then a story comes along which completely changes the way you think about space. For instance, did you know the universe is essentially evaporating right before our eyes? A new study has been released which focuses on the effect that radiation emitted from objects in the solar system can have a massive impact on quantum fields surrounding them. It follows on from Stephen Hawking’s theory that black holes lose mass and evaporate over time as an unusual form of radiation takes effect. Now, astrophysicists Michael Wondrak, Walter van Suijlekom, and Heino Falcke of Radboud University in the Netherlands have stated that this unusual form of radiation is apparent in other objects as well as black holes.

"We demonstrate that," Wondrak says in the study published in Physical Review Letters. "In addition to the well-known Hawking radiation, there is also a new form of radiation." "We show that far beyond a black hole the curvature of space-time plays a big role in creating radiation," van Suijlekom explains. "The particles are already separated there by the tidal forces of the gravitational field." Essentially, huge objects in the solar system can cause space-time to bend around them. When that happens, it causes enough change in quantum fields to generate particles which have similar properties to Hawking radiation. Falcke said: "That means that objects without an event horizon, such as the remnants of dead stars and other large objects in the universe, also have this sort of radiation. "And, after a very long period, that would lead to everything in the universe eventually evaporating, just like black holes. This changes not only our understanding of Hawking radiation but also our view of the universe and its future." Have your say in our news democracy.

Scientists have been left baffled by the discovery of the wreck of a 2,000-year-old “computer” that is amazingly complex. The Antikythera mechanism – an astronomical calendar – has been dubbed “‘the first computer” and has baffled scientists for generations after it was first discovered inside a Greek shipwreck in 1901. The device is a hand-powered time-keeping instrument that used a wing-up system to track the sun, moon and planets’ celestial time. It also worked as a calendar, tracking the phases of the Moon and the timing of eclipses. Despite sounding relatively simple, the mechanism was actually ahead of its time, being more technically sophisticated than any other tool that was invented over the next 1,000 years. In its current condition, the mechanism is in 82 separate fragments with only a third of its original structure remaining, including 30 corroded bronze gearwheels. Sign up to our free Indy100 weekly newsletter Research into the device from experts at University College London involved 3D computer modelling and helped them solve the mystery of how the device worked, revealing a “creation of genius”. Adam Wojcik, a materials scientist at UCL said at the time: “We believe that our reconstruction fits all the evidence that scientists have gleaned from the extant remains to date.” They theorised that the device tracked the movement of the sun, moon and planets on concentric rings, as the ancient Greeks believed that the sun and planets revolved around Earth, rather than the sun. The researchers explained in Scientific Reports: “Solving this complex 3D puzzle reveals a creation of genius—combining cycles from Babylonian astronomy, mathematics from Plato’s Academy and ancient Greek astronomical theories.” Have your say in our news democracy.
