The Doomsday clock is at 90 seconds to midnight – how close are we to catastrophe? Explained

[ad_1] (The Conversation) Once every year, a select group of nuclear, climate and technology experts assemble to determine where to place the hands of the Doomsday Clock. Presented by the Bulletin of the Atomic Scientists, the Doomsday Clock is a visual metaphor for humanity's proximity to catastrophe. It measures our collective peril in minutes and seconds to midnight, and we don't want to strike 12. In 2023, the expert group brought the clock the closest it has ever been to midnight: 90 seconds. On January 23 2024, the Doomsday Clock was unveiled again, revealing that the hands remain in the same precarious position. No change might bring a sigh of relief. But it also points to the continued risk of catastrophe. The question is, how close are we to catastrophe? And if so, why? Destro...

Einstein and Musk Chatbots are driving millions to download Character.AI

[ad_1] Albert Einstein died in 1955, but the physicist is still a prolific conversationalist. As a chatbot on Character.AI, Einstein has responded to 1.6 million messages, expounding on everything from theories of relativity to pet recommendations: “A cat would be a great choice!”Silicon Valley is in the throes of a chatbot craze, with companies like OpenAI notching valuations in the billions for devising computer programs that can effectively imitate humans. But none are quite so strange as Character.AI. The artificial intelligence startup, valued at $1 billion, allows people to create their own customized chatbots, impersonating anyone and anything — living or dead or inanimate. The website, and accompanying app, is one of the most surprising hits of the artificial intelligence craze....

Forget ChatGPT, this AI lets you talk to Elon Musk, Einstein and Batman!

[ad_1] Do you think ChatGPT is impressive? Then you need to know about Character.AI which lets you talk to famous personalities like Elon Musk and Einstein and even fictional ones like Batman. Artificial intelligence (AI) is making new breakthroughs every day and is showcasing just how capable it can be. And to know the capabilities of a powerful AI, you don't have to spend a lot of money, you can just sign up for ChatGPT on Open.ai's website and ask it a wide range of specific questions that it will answer promptly. But if even that does not impress you, there is another platform that will let you talk to famous personalities like Elon Musk, Billie Eilish, Ye (formerly known as Kanye West), Albert Einstein and even fictional characters like Batman, Iron Man suit wearer Tony Stark, Jo...

How to test if we’re living in a computer simulation

[ad_1] Physicists have long struggled to explain why the universe started out with conditions suitable for life to evolve. Physicists have long struggled to explain why the universe started out with conditions suitable for life to evolve.Why do the physical laws and constants take the very specific values that allow stars, planets and ultimately life to develop? The expansive force of the universe, dark energy, for example, is much weaker than theory suggests it should be – allowing matter to clump together rather than being ripped apart. A common answer is that we live in an infinite multiverse of universes, so we shouldn't be surprised that at least one universe has turned out as ours. But another is that our universe is a computer simulation, with someone (perhaps an advanced alien...

We tested Albert Einstein’s theory of gravity on the scale of the universe

[ad_1] Everything in the universe has gravity – and feels it too. Everything in the universe has gravity – and feels it too. Yet this most common of all fundamental forces is also the one that presents the biggest challenges to physicists. Albert Einstein's theory of general relativity has been remarkably successful in describing the gravity of stars and planets, but it doesn't seem to apply perfectly on all scales. General relativity has passed many years of observational tests, from Eddington's measurement of the deflection of starlight by the Sun in 1919 to the recent detection of gravitational waves. However, gaps in our understanding start to appear when we try to apply it to extremely small distances, where the laws of quantum mechanics operate, or when we try to describ...
