As the common tropes of science fiction continue to break out into reality, from humanoid robots to self-driving cars, there’s one concept that has seemingly remained beyond our grasp: time travel.

But, jumping through time might not be impossible, after all, according to one astrophysicist.

By the rules of theoretical physics, certain conditions exist that would allow for the construction of elaborate wormholes, which could transport humans back to different eras.

While scientists have yet to discover the conditions needed to travel back in time, and construction a system large enough for humans certainly wouldn’t be easy, ‘there’s nothing forbidding it’ in the laws of theoretical physics, explains astrophysicist Ethan Siegel of Lewis & Clark College in the Forbes blog Starts With A Bang.

Backward time travel would rely on the elusive counterpart to the known positive energy / positive or zero mass particles found all throughout the universe – the negative mass/energy particles, which have long been theorized but never yet found.

‘If this negative mass/energy matter exists, then creating both a supermassive black hole and the negative mass/energy counterpart to it, while then connecting them, should allow for a traversable wormhole,’ Siegel writes.

NASA is set to begin testing a radical ‘nuclear engine’ that could provide power for astronauts on the Martian surface.

Dubbed the ‘Kilopower’ it would use a uranium rector the size of a toilet roll to create heat.

A high efficiency Stirling engine would then convert this to electricity, in a system that works in a similar way to a car engine.

A group of security researchers has remotely hacked a Boeing 757 aircraft without the knowledge of the pilots, a US government official has claimed.

Robert Hickey, a Homeland Security cyber investigator, managed to take over the passenger jet on the runway at Atlantic City airport, New Jersey.

A Boeing official has said the test is unlikely to indicate a major threat to airliners, adding: ‘I’m not afraid to fly’.

Washington (AFP) — Police in the US state of Delaware are poised to deploy “smart” cameras in cruisers to help authorities detect a vehicle carrying a fugitive, missing child or straying senior.

The video feeds will be analyzed using artificial intelligence to identify vehicles by license plate or other features and “give an extra set of eyes” to officers on patrol, says David Hinojosa of Coban Technologies, the company providing the equipment.

“We are helping officers keep their focus on their jobs,” said Hinojosa, who touts the new technology as a “dashcam on steroids.”

L amborghini has created the world’s first self-healing sports car. The Terzo Millennio, which translates as third millennium in Italian, has the ability to detect and repair cracks in its body work.

Using sensors the car can conduct its own health check to detect any damages and self-repair itself by filling the crack with nanotubes to prevent it spreading.

The super car was created in collaboration with researchers from the Massachusetts Institute of Technology (MIT) in Boston.

Las Vegas’ newest tourist attraction has nothing to do with casinos, neon lights or Cirque du Soleil. It’s a driverless shuttle that will make a half-mile loop all day long on city streets in the downtown Fremont East district, starting Wednesday.

AAA of Northern California, Nevada & Utah is sponsoring the yearlong pilot program along with two French companies: Keolis, a global transportation company that already runs Las Vegas’ public bus system, and Navya, which manufactures the driverless shuttle. The goal is twofold: to expose the public to the futuristic technology and gain insights on how people view it.

“Las Vegas prides itself on being first, getting out there and trying out new things,” said city spokesman Jace Radke.

Flying Ubers are coming to LA: Ride-sharing company links with NASA to bring 200mph electric aircraft to the city in 2020 and a flight will cost you the same as a car journey…

Uber’s Chief Product Officer, Jeff Holden, announced the plans at the global Web Summit in Lisbon today.

Mr Holden said: ‘Technology will allow LA residents to literally fly over the city’s historically bad traffic, giving them time back to use in far more productive ways.

‘At scale, we expect UberAIR will perform tens of thousands of flights each day across the city — at those levels, all the time savings will have a noticeable positive impact on the region’s economy.’
