Live Science spoke with physicist David Gross, who today received the $3 million "Special Breakthrough Prize in Fundamental Physics". He was part of a trio that won the 2004 physics Nobel prize for research that helped complete the Standard Model of particle physics. But when asked if physics will reach a unified theory of the fundamental forces of nature within 50 years, Gross has a surprising answer. "Currently, I spend part of my time trying to tell people... that the chances of you living 50 [more] years are very small." Cold War estimates for a 1% chance of nuclear war each year seem low, Gross says. "The chances are more likely 2%. So that's a 1-in-50 chance every year." David Gross: The expected lifetime, in the case of 2% [per year], is about 35 years. [The expected lifetime is the average time it would take to have had a nuclear war by then. It is calculated using similar equations as those used to determine the "half-life" of a radioactive material.] Live Science: So what do you suggest as remedies to lower that risk? Gross: We had something called the Nobel Laureate Assembly for reducing the risk of nuclear war in Chicago last year. There are steps, which are easy to take — for nations, I mean. For example, talk to each other. In the last 10 years, there are no treaties anymore. We're entering an incredible arms race. We have three super nuclear powers. People are talking about using nuclear weapons; there's a major war going on in the middle of Europe; we're bombing Iran; India and Pakistan almost went to war. OK, so that's increased the chance [of nuclear war]. I would really like to have a solid estimate — it might be more, and I think I'm being conservative — but a 2% estimate [of nuclear war] in today's crazy world. Live Science: Do you think we'll ever get to a place where we get rid of nuclear weapons? Gross: We're not recommending that. That's idealistic, but yes, I hope so. Because if you don't, there's always some risk an AI 100 years from now [could launch nuclear weapons], but chances of [humanity] living, with this estimate, 100 years, is very small, and living 200 years is infinitesimal. So [the answer to] Fermi's question of "Where are the civilizations, all the intelligent organisms around the galaxy, and why don't they talk to us?" is that they've killed themselves... There are now nine nuclear powers. Even three is infinitely more complicated than two. The agreements, the norms between countries, are all falling apart. Weapons are getting crazier. Automation, and perhaps even AI, will be in control of those instruments pretty soon... It's going to be very hard to resist making AI make decisions because it acts so fast. He points out that with the threat of climate change, "people have done something," even though "It's a much harder argument to make than about nuclear weapons. "We made them; we can stop them."

alternative_right quotes a report from the New York Post: The CIA used a futuristic new tool called "Ghost Murmur" to find and rescue the second American airman who was shot down in southern Iran, The Post has learned. The secret technology uses long-range quantum magnetometry to find the electromagnetic fingerprint of a human heartbeat and pairs the data with artificial intelligence software to isolate the signature from background noise, two sources close to the breakthrough said. It was the tool's first use in the field by the spy agency -- and was alluded to Monday afternoon by President Trump and CIA Director John Ratcliffe at a White House briefing. "It's like hearing a voice in a stadium, except the stadium is a thousand square miles of desert," a source briefed on the program told The Post. "In the right conditions, if your heart is beating, we will find you." The relatively barren landscape made for "an ideal first operational use" of Ghost Murmur, the first source noted. "Normally this signal is so weak that it can only be measured in a hospital setting with sensors pressed nearly against the chest," the source said. "But advances in a field known as quantum magnetometry -- specifically sensors built around microscopic defects in synthetic diamonds -- have apparently made it possible to detect these signals at dramatically greater distances." "The capability is not omniscient. It works best in remote, low-clutter environments and requires significant processing time," this person added.
