But is it theoretically even possible to time travel?

In the original 1978 Superman film, Superman goes back in time by flying around the globe faster than the speed of light. This is incredibly fast – the speed of light is just under 300,000 km per second!

So far, we have not come even close to this speed, the fastest man-made object, a space probe, traveled at just 150 km per second.

Given the right technological advancements, is it theoretically possible for us to travel faster than the speed of light, and thus, like superman, travel in time?

All the experts agreed that it is not possible to travel faster than the speed of light, this is also specified in Einstein's theory.

Dr Eric Tittley, an expert in astronomy and astrophysics from the University of Edinburgh, explains, "It is clear that no object or information can travel faster than the speed of light. It is not a question of not having enough energy to push it that fast. From an external perspective, any extra energy added to a body to get it to and past the speed of light just asymptotically accelerates it to the speed of light."

Tesla will branch out from building electric, self-driving cars to produce humanoid robots designed to “eliminate dangerous, repetitive, boring tasks” and respond to voice commands from their owners.

The robot, referred to as Optimus by those inside the company, will be 173 centimetres tall and weigh 57 kilograms. Its body will be powered by 40 electromechanical actuators and its face will feature a screen display.

Optimus will be able to carry a cargo of up to 20 kilograms, and Tesla’s CEO Elon Musk claims that a working prototype will be ready next year.

Speaking at the company’s AI Day event, designed to attract engineering and research talent to the company, Musk said that much of the technology in Tesla’s self-driving cars is applicable to or useful in creating humanoid robots.

“Tesla is arguably the world’s biggest robotics company because our cars are like semi-sentient robots on wheels,” he said. “It kind of makes sense to put that onto a humanoid form. We’re also quite good at sensors and batteries and actuators.”

An anonymous hacker who stole more than $600 million from the decentralized finance platform Poly Network this week has returned virtually all of the money — and apparently turned down a half-million-dollar reward offered by the company for exposing its security vulnerability. The bizarre outcome caps off an unusual cryptocurrency heist that has been called the biggest in industry history.

Apple has announced details of a system to find child sexual abuse material (CSAM) on US customers' devices.

Before an image is stored onto iCloud Photos, the technology will search for matches of already known CSAM.

Apple said that if a match is found a human reviewer will then assess and report the user to law enforcement.

However there are privacy concerns that the technology could be expanded to scan phones for prohibited content or even political speech.

Experts worry that the technology could be used by authoritarian governments to spy on its citizens.

The new fiber could help satisfy demand for 6G and beyond.

The many-gigabit internet speed records of a decade ago now seem downright inadequate. Motherboard reports that scientists at Japan's National institute of Information and Communications Technology (NICT) have smashed the internet transfer record by shuffling data at 319Tbps. For context, that's almost twice as fast as the 179Tbps a team of British and Japanese researchers managed in August 2020.

NICT managed the feat by upgrading virtually every stage of the pipeline. The fiber optic line had four cores instead of one, and researchers fired a 552-channel comb laser at multiple wavelengths with the assistance of rare earth amplifiers. While the test was strictly confined to the lab, the team used coiled fiber to transfer data at a simulated 1,864-mile distance without losing signal quality or speed.

Originally built to speed up calculations, a machine-learning system is now making shocking progress at the frontiers of experimental quantum physics.

Quantum physicist Mario Krenn remembers sitting in a café in Vienna in early 2016, poring over computer printouts, trying to make sense of what MELVIN had found. MELVIN was a machine-learning algorithm Krenn had built, a kind of artificial intelligence. Its job was to mix and match the building blocks of standard quantum experiments and find solutions to new problems. And it did find many interesting ones. But there was one that made no sense.

“The first thing I thought was, ‘My program has a bug, because the solution cannot exist,’” Krenn says. MELVIN had seemingly solved the problem of creating highly complex entangled states involving multiple photons (entangled states being those that once made Albert Einstein invoke the specter of “spooky action at a distance”). Krenn and his colleagues had not explicitly provided MELVIN the rules needed to generate such complex states, yet it had found a way. Eventually, he realized that the algorithm had rediscovered a type of experimental arrangement that had been devised in the early 1990s. But those experiments had been much simpler. MELVIN had cracked a far more complex puzzle.

When Microsoft said that it was going to announce the next version of Windows on June 24, it was only a matter of time before the leaks started coming. The first Windows 11 build leaked today, first offering up some screenshots on Baidu. Now, the full build is here.

First of all, we should be clear that this is very much a new version of Windows 10. It has a big visual redesign, but under the hood, this is the same OS. Microsoft wanted to build excitement around it, so that’s why we’re getting the new branding. Because of this, the first thing you’ll see when booting up this leaked build is a very familiar out-of-box experience.

Indeed, all of the different Windows 11 versions are the same as they were for Windows 10, including Home, Pro, Enterprise, and more. Once you get past that part where you choose your edition, decide how to partition your drive, and it actually installs the bits, that’s where the OOBE takes a left turn from what’s familiar.

NASA's new chief is setting up an effort to further study unidentified flying objects within his first month in office.

Bill Nelson, the former Florida senator and spaceflight veteran, told CNN Business' Rachel Crane during a wide-ranging interview on Thursday that it's not clear to anyone — even in the upper echelons of the US space agency — what the high-speed objects observed by Navy pilots are.

Nelson added that he does not believe the UFOs are evidence of extraterrestrials visiting Earth. "I think I would know" if that were the case, Nelson said. But, he acknowledged, it'd be premature to rule that out as a possibility.

Nelson's comments echo the findings of a new Pentagon report expected to be released later this month. Five sources familiar with the results of that study told CNN that US intelligence officials found no evidence that the UFOs are alien spacecraft, but investigators also have not reached a definitive assessment as to what these mysterious objects might be.

"We don't know if it's extraterrestrial. We don't know if it's an enemy. We don't know if it's an optical phenomenon," Nelson said. "We don't think [it's an optical phenomenon] because of the characteristics that those Navy jet pilots described ... And so the bottom line is, we want to know."

NASA’s Curiosity rover has captured images of clouds on Mars— as described in its blog post: “wispy puffs filled with ice crystals that scattered light from the setting sun, some of them shimmering with color.”

According to NASA clouds are rare in the thin atmosphere of Mars, but usually form at its equator during its coldest time of year. Scientists noticed that last year — two years ago in Earth time— there were clouds beginning to form earlier than expected, so this year they were ready.

If you use Alexa, Echo, or any other Amazon device, you have only 10 days to opt out of an experiment that leaves your personal privacy and security hanging in the balance.

On June 8, the merchant, Web host, and entertainment behemoth will automatically enroll the devices in Amazon Sidewalk. The new wireless mesh service will share a small slice of your Internet bandwidth with nearby neighbors who don’t have connectivity and help you to their bandwidth when you don’t have a connection.

By default, Amazon devices including Alexa, Echo, Ring, security cams, outdoor lights, motion sensors, and Tile trackers will enroll in the system. And since only a tiny fraction of people take the time to change default settings, that means millions of people will be co-opted into the program whether they know anything about it or not. The Amazon webpage linked above says Sidewalk "is currently only available in the US."

Microsoft said it is retiring Internet Explorer, the browser it created more than 25 years ago and which is now largely abandoned as people instead use competitors like Google's Chrome or Apple's Safari.

"We are announcing that the future of Internet Explorer on Windows 10 is in Microsoft Edge," the company said in a blog post Wednesday, referring to its other browser.

"Not only is Microsoft Edge a faster, more secure and more modern browsing experience than Internet Explorer, but it is also able to address a key concern: compatibility for older, legacy websites and applications," Microsoft said.
