Our universe certainly seems real, but in recent years, a growing number of scientists have begun to wonder if it's all just a sophisticated simulation. Are we and everything around us nothing more than points of data in some sort of cosmic hologram? A group of celebrated scientists, including Neil deGrasse Tyson, will sit down on Tuesday for a serious discussion of what may sound more like a sci-fi movie plot than reality. The event at New York City's American Museum of Natural History starts at 7 p.m. Eastern time. You can watch it live in the video above.

I believe Richard Feynman was one of our greatest scientific minds. He had a very particular way of looking at the world thanks to his father, and it was to look at the world around him as if he were a Martian. Like a fish born into water, it's hard to actually see water as being water, because it's all a fish ever knows. And so as humans, it's a good idea to try and step outside of our usual frame of mind, to see what it is we as humans think and do, from the perspective of a mind totally alien to our everyday environment. With that in mind, here's what humans are doing right now, from the perspective of someone from far, far away... What an interesting place and an interesting time it is for a visit.

IBM is currently attempting to merge artificial intelligence and the blockchain into a single, powerful prototype. With blockchain tech's promise of near-frictionless value exchange and artificial intelligence's ability to accelerate the analysis of massive amounts of data, the joining of the two could mark the beginning of an entirely new paradigm. Over the past three months, IBM's chief architect in charge of Internet of Things security Tim Hahn has focused specifically on introducing the blockchain to his company's artificially intelligent computer named Watson. "What we're doing with blockchain and devices is enabling the information those devices supply to effect the blockchain…You begin to approach the kind of things we see in movies." Potential applications include using distributed ledgers to perform tasks like running self-diagnoses at set times to more advanced services that may someday let regulators virtually go back in time to the point where a device failed and "to identify exactly what went wrong," Hahn said.

Imagine if you had a rare, undiagnosed disease that's stumped doctor after doctor. What if there were a single, secure database that could read your symptoms then run through thousands of clinical studies, similar patient records, and medical textbooks to present a risk-matched list of potential diseases? Just one year after its launch, IBM Watson Health is already starting to make this seemingly impossible task a reality, thanks to its powerful cognitive computing platform and a wide-reaching partnership strategy. Watson's vision is to enable better care by surfacing insights from the massive amounts of personal and academic health data that's being generated every day, but IBM ibm needs partners within the medical, pharmaceutical, and hospital fields to make that relevant to on-the-ground practitioners. It's institutions and companies like the Mayo Clinic, CVS Health cvs, and Memorial Sloan Kettering Cancer Center that are adapting the innovative new technology to real-life applications.

Nvidia chief executive Jen-Hsun Huang announced that the company has created a new chip, the Tesla P100, with 15 billion transistors for deep-learning computing. It's the biggest chip ever made, Huang said. Huang made the announcement during his keynote at the GPUTech conference in San Jose, Calif. He unveiled the chip after he said that deep learning artificial intelligence chips have already become the company's fastest-growing business. "We are changing so many things in one project," Huang said.

Nvidia chief executive Jen-Hsun Huang said that deep learning artificial intelligence has become a new computing platform, and the company is dealing with hundreds of startups in the space that plan to take advantage of the platform. Speaking at the GPUTech conference in San Jose, Calif., Huang noted that 5 billion was invested last year in A.I. startups, and there are probably a thousand companies working on the technology for applications ranging from face recognition to self-driving cars. "Deep learning is not an industry," he said. "Deep learning is going to be in every industry. Deep learning is going to be in every application."

The dawn of drones is ushering in a fundamental shift in how we do things--it's affecting everything from lifestyle to privacy, logistics to entertainment. Yet one obvious (but largely untapped) potential use for unmanned aerial vehicles is its capacity to aid emergency services. While not completely unheard of (there have been talks of using drone technology for search and rescue missions or combat poaching), this is the first time that its capability is actually going to be tested. And according to a recent announcement, Rwanda is going to be the first country that will make use of delivery drones to ferry medical supplies around the country. Zipline, a drone startup, is behind the initiative, working in partnership with the Rwandan government.

Nvidia's varied range of GPU developer tools have been spread out into specialized kits, but that's not the case any more. The company has announced the Nvidia SDK unified toolkit, which brings together its game development, supercomputing, virtual reality, automotive and drone and robot development tools into one package. The toolkit brings together essential tools and libraries necessary for GPU development, Jen-Hsun Huang, CEO of Nvidia, said during a keynote at the company's GPU Technology Conference in San Jose, California. The toolkit is tuned for Nvidia's latest Pascal GPU architecture, which the company is expected to detail at the show. Pascal contains many technological improvements that could trigger changes in the way applications are written for GPUs.

Trips to the mechanics can be intimidating and often expensive for those unfamiliar with what's under their car's hood. But vehicles of the future could detect maintenance issues and fix them before they become a problem, potentially putting mechanics out of work. Hyundai is working on a'smart maintenance service' that it claims will'remotely diagnose and fix vehicle issues before they become apparent.' Cars of the future could detect maintenance issues and fix them before they become a problem, potentially putting mechanics out of work. However, no more details have been revealed and MailOnline has asked the firm to clarify.

Sianagh Gallagher of York was born without a left arm, shoulder blade or collarbone -- but that didn't stop her from taking up rock-climbing nine years ago, and becoming the captain of her country's paraclimbing team. "Growing up with my disability never really held me back from doing anything. If anything, I was more determined to get things done and prove myself to people," Gallagher, 19, told Barcroft Media. Gallagher -- Europe's lone paraclimber -- struggled to learn how to tie her shoes and peel an egg, but was at ease working her way to the top of a rock wall. "It was the first time I'd been really good at a sport," she said.
