Is The Multiverse Real? The Science Behind ‘Everything Everywhere All At Once’

Posted by in categories: cosmology, entertainment, science

Do multiverses exist? Is our universe one of many? The multiverse is a key plot device in the hit movie Everything Everywhere All At Once.

But does the multiverse have any basis in science?


Oscars 2023: Cosmologists are trying to figure out if there’s a group of multiple universes running parallel to each other—as seen in the hit movie “Everything Everywhere All At Once”—and whether they might be habitable.

Controversial Exhibit: AI says “sorry” for wiping out humanity

Posted by in categories: existential risks, robotics/AI

A post-apocalyptic exhibit features an AI that expresses remorse for being the reason for the near-extinction of humanity.

The beating heart of tech-revolution, a museum in San Francisco, has visualized a memorial to the extinction of the human race, considering the fast and significant advances coming in artificial intelligence.

The pieces in the temporary exhibition combine the frightening with the humorous.

In a first, scientists show time reflection of electromagnetic waves

Posted by in categories: computing, physics

The breakthrough experiment could lead to low-energy, wave-based computers and new applications for wireless communications.

Researchers at the Advanced Science Research Center at the CUNY Graduate Center (CUNY ASRC) performed a breakthrough experiment in which they observed time reflections of electromagnetic signals in a tailored metamaterial.

Time reflection versus spatial reflection.

Meta creates new, ‘inclusive’ AI training dataset so bots can be fair

Posted by in category: robotics/AI

It could be a solid step against inaccurate, racist, and sexist responses from the likes of OpenAI’s ChatGPT and Google’s Bard.

Meta hopes to assist AI researchers in making their tools and procedures more universally inclusive, with the launch of Casual Conversations v2, according to a statement from the firm on March 9.

The vast new dataset, which includes face-to-face video clips from a broad spectrum of human participants across varied geographic, cultural, racial, and physical demographics, serves as an upgrade to its 2021 AI audio-visual training dataset.

Making Deepfakes Gets Cheaper and Easier Thanks to A.I.

Posted by in category: robotics/AI

It wouldn’t be completely out of character for Joe Rogan, the comedian turned podcaster, to endorse a “libido-boosting” coffee brand for men.

But when a video circulating on TikTok recently showed Mr. Rogan and his guest, Andrew Huberman, hawking the coffee, some eagle-eyed viewers were shocked — including Dr. Huberman.

The Limits of Computing: Why Even in the Age of AI, Some Problems Are Just Too Difficult

Posted by in categories: biotech/medical, information science, media & arts, robotics/AI

Empowered by artificial intelligence technologies, computers today can engage in convincing conversations with people, compose songs, paint paintings, play chess and go, and diagnose diseases, to name just a few examples of their technological prowess.

These successes could be taken to indicate that computation has no limits. To see if that’s the case, it’s important to understand what makes a computer powerful.

In defense of space colonies and mining the high frontier

Posted by in categories: energy, finance, internet, satellites, sustainability

Exploiting the natural and energy resources of the moon and asteroids can spark a space-based industrial revolution that could be a boon to all humankind. Pure science alone will be enough reason for the people who pay the bills to finance space exploration. Accessing the wealth that exists beyond the Earth is more than enough incentive for both public and private investment. Science will benefit. Someone will have to prospect for natural and energy resources in space and to develop safe and sustainable ways to exploit it.

Conflict between scientists and commercial space is already happening. Astronomers complain that SpaceX’s Starlink satellite internet constellation is ruining ground-based observation. Some critics fear that commercial exploitation of the moon’s resources will impede the operation of telescopes on the far side of the moon.
