Students at the Oregon State University were warned to “avoid all robots” following a bomb threat prank involving automated food delivery machines on campus. The threat was made by a student on Tuesday via social media, causing university staff to issue the urgent warning. “Bomb Threat in Starship food delivery robots. Do not open robots. Avoid all robots until further notice. Public Safety is responding,” the institute wrote on X, formerly known as Twitter. The university later provided several updates on the unfolding situation, saying that the robots had been isolated in a “safe location” before being inspected by a technician. Students were advised to “remain vigilant for suspicious activity”. The emergency was declared over just before 2pm local time with “normal activities” resuming. “All robots have been inspected and cleared. They will be back in service by 4pm today,” the university later wrote online. Starship, the company that designs the robots, said that despite the student’s subsequent admission that the bomb threat had been “a joke”, it had suspended the service while investigations were ongoing. In its own statement, the company wrote: “A student at Oregon State University sent a bomb threat, via social media, that involved Starship’s robots on the campus. “While the student has subsequently stated this is a joke and a prank, Starship suspended the service. “Safety is of the utmost importance to Starship and we are cooperating with law enforcement and the university during this investigation.” Read More University of Michigan slithers toward history with massive acquisition of jarred snake specimens Trump boasts that he ‘killed’ Tom Emmer’s speaker bid ‘Bandaid on an open chest wound’: Democrats mock latest speaker chaos

They may not be as stylish as a DeLorean or as sturdy as a blue police box, but wormholes in space could hold the key to real-life time travel – and a team of experts think they’ve figured out how. The trio of scientists delved deep into the laws of physics and discovered that it might be possible for humans to one day zip across galaxies in a matter of seconds, or journey through time itself. Now, this is all to do with the general theory of relativity and quantum physics, so don’t expect to get your head around it too easily. However, in their paper, Valeri P. Frolov and Andrei Zelnikov of Canada’s University of Alberta, and Pavel Krtouš of Prague’s Charles University proposed that a specific kind of wormhole would “inevitably” be “transformed into a time machine” if it was subject to particular conditions. Sign up for our free Indy100 weekly newsletter For the uninitiated, wormholes can be described as spacetimes in which a “kind of tunnel exists connecting distant parts in the universe”. The main problem with them is… they don’t actually exist. At least not in any tangible way. As Drs Eric Christian and Louis Barbier put it in an explainer for NASA: “Wormholes are allowed to exist in the math of ‘General Relativity’, which is our best description of the Universe. “Assuming that general relativity is correct, there may be wormholes. But no one has any idea how they would be created, and there is no evidence for anything like a wormhole in the observed Universe.” Still, numerous experts in the field of gravitation and general relativity have spent years or even decades working on them, including Stephen Hawking in his time. For their paper, Frolov, Krtouš, and Zelnikov explored what is known as a ring wormhole, which was first described in 2016 by theoretical physicist Gary Gibbons, of Cambridge University, and Mikhail Volkov of the University of Tours. Unlike the spherical contortions of spacetime we might attribute to black holes, the ring wormhole proposed by Gibbons and Volkov connects sections of the universe (or, indeed, different universes) which are generally described as “flat”, as ScienceAlert notes. Ring-shaped masses could potentially create some pretty remarkable distortions in what would otherwise be flat spacetime if you consider how their electrical and magnetic fields might interact. And so Frolov, Krtouš, and Zelnikov decided to consider two types of such wormholes: “a wormhole connecting to flat spaces; and a wormhole connecting two distant domains in the same space”. For the latter, they concluded that if a “massive thin shell” surrounded one of the mouths of the ring wormhole, a “closed timelike curve” would form. This, as the name suggests, would mean that any travelling object (or ray of light) would come back to the exact same point whence it began. In other words, you could travel in space and time and return to your point of departure. The most exciting aspect of ring wormholes, as the authors point out is that: “For the ring wormhole an observer passing through it moves in a flat (or practically flat spacetime), while in the case of ‘standard’ (spherical) wormholes he/she should pass a domain filled with the matter violating the null energy condition.” Even without knowing what the “null energy condition” is, you can appreciate that the first option sounds a lot simpler. Now, before you start calling yourself Marty McFly or making a list of all the past mistakes you’d like to correct, we should stress that we’re a long way off seeing the creation of a bonafide, buckle-your-seatbelt time machine. But at least, thanks to the efforts of experts like Frolov, Krtouš, and Zelnikov, we’re at least one step closer to going back in the future. Have your say in our news democracy.

Nasa’s James Webb Space Telescope has spotted a “fluffy” planet with an atmosphere made up of a collection of intriguing materials. The planet has a similar water and cloud cycle to that of our own Earth. But the clouds are made of sand and the clouds are made of silicate. Other parts of the atmosphere are more like our own and could be an intriguing hint of the telescope’s ability to investigate planets that might be home to distant alien life. Data gathered using the telescope revealed that WASP-107b - a planet 200 lightyears away that orbits a star in the constellation of Virgo - has a dynamic atmosphere made up of water vapour, sulphur dioxide, and sand clouds. Scientists say this exoplanet - a planet outside the Solar System - has a cloud cycle similar to Earth, except the droplets are made of sand instead of water vapour. While clouds have been inferred on other exoplanets, the researchers said their work, published in the journal Nature, is the first instance where astronomers have been able to identify the chemical composition of clouds in a distant planet. Study author Dr Achrene Dyrek, an astronomer at CEA - a French government-funded research organisation in Paris, said: “JWST enables a deep atmospheric characterisation of an exoplanet that does not have any counterpart in our Solar System, we are unravelling new worlds!” European astronomers used JWST’s Mid-Infrared Instrument (MIRI) to peer deep into WASP-107b’s atmosphere. WASP-107b is just a little smaller than Jupiter but its mass is less than 10% of the gas giant. This makes it one of the lowest density exoplanets known, thus earning the label “fluffy” - like candyfloss. The fluffiness of this exoplanet allowed astronomers to look much deeper into the atmosphere - roughly 50 times deeper compared to Jupiter - revealing its complex chemical composition. While the team found the presence of water vapour, SO2, and silicate clouds, they said the greenhouse gas methane (CH4) was notably absent, hinting at “a potentially warm interior”. Just like clouds on Earth, the sand clouds high in WASP-107b’s atmosphere undergo a continuous cycle of sublimation and condensation. Study author Dr Michiel Min, a senior scientist at the SRON Netherlands Institute for Space Research, said: “The fact that we see these sand clouds high up in the atmosphere must mean that the sand rain droplets evaporate in deeper, very hot layers and the resulting silicate vapour is efficiently moved back up, where they recondense to form silicate clouds once more. “This is very similar to the water vapour and cloud cycle on our own Earth but with droplets made of sand.” The researchers said their work marks “a significant milestone” in understanding more about the climatic conditions of other exotic worlds. Study author Professor Leen Decin, of KU Leuven in Belgium, said: “The discovery of clouds of sand, water, and sulphur dioxide on this fluffy exoplanet by JWST’s MIRI instrument is a pivotal milestone. “It reshapes our understanding of planetary formation and evolution, shedding new light on our own Solar System.” Additional reporting by agencies Read More Ring to preview security features with abuse charity to boost safety WhatsApp users warned they will soon have to pay to keep old messages and photos TikTok launches feature to save songs to music apps like Spotify Ring to preview security features with abuse charity to boost safety WhatsApp users warned they will soon have to pay to keep old messages and photos TikTok launches feature to save songs to music apps like Spotify
