Taiwan Semiconductor Manufacturing Co. will offer advanced 4-nanometer chips when its new $12 billion plant in Arizona opens in 2024, an upgrade from its previous public statements, after US customers such as Apple Inc. pushed the company to do so, according to people familiar with the matter.
25 years ago, the film Contact made its theatrical debut starring Jodie Foster and Matthew McConaughey and told the story of Dr. Eleanor Arroway (Jodie Foster) who picked up a radio signal from the star Vega and how this discovery impacted not just herself, but humanity as a whole. Over time, she discovers the signal has embedded instructions sent by the aliens to build a device capable of sending one person into outer space, presumably to meet the Vegans.
The device is built, and she is eventually hurled through a series of outer space tunnels where she meets an alien in the form of her long-deceased father. Right before she’s sent back home, the alien informs her, “This was just a first step. In time you’ll take another.” When she awakens, her colleagues inform her the pod she sat in fell straight through the device and she never actually left. With no hard evidence of both her travels and meeting the aliens, Eleanor is left scrutinized by both the public and Congress. She is ultimately given a “healthy grant” to fund further research into finding more signals from ET, and the film ends with her pondering her journey to the stars.
While some moviegoers were bummed that they didn’t see the aliens—who instead downloaded Jodie Foster’s consciousness so they could talk to her easier—the important message of the film, and the book that it’s based on, is to persevere, but also knowing there will be hardships and sacrifices along the way. In the case of Eleanor, she loses her father at a very young age who had gotten her hooked on astronomy. Later, she passes on love with Palmer Joss (Matthew McConaughey) to remain in pursuit of her research, all while consistently being roadblocked by her former boss. And even after she reaches her goal of contacting the aliens who sent the message, she’s still scrutinized and ridiculed.
“Houston, we have a new record.”
NASA’s Artemis I Orion capsule broke a new spaceflight record. The uncrewed Orion reached a distance from Earth of 249,666 miles (from 401,798 kilometers) on Saturday, November 26, at 10:17 am. ET, meaning it surpassed a record set by Apollo 13 in 1970 for the furthest distance traveled from Earth by a spacecraft designed to carry humans.

Vitaly Vanchurin, physicist and cosmologist at the University of Minnesota Duluth speaks to Luis Razo Bravo of EISM about the world as a neural network, machine learning, theories of everything, interpretations of quantum mechanics and long-term human survival.

SPEAKING at the University of Cambridge in 1980, Stephen Hawking considered the possibility of a theory of everything that would unite general relativity and quantum mechanics – our two leading descriptions of reality – into one neat, all-encompassing equation. We would need some help, he reckoned, from computers. Then he made a provocative prediction about these machines’ growing abilities. “The end might not be in sight for theoretical physics,” said Hawking. “But it might be in sight for theoretical physicists.”
Artificial intelligence has achieved much since then, yet physicists have been slow to use it to search for new and deeper laws of nature. It isn’t that they fear for their jobs. Indeed, Hawking may have had his tongue firmly in his cheek. Rather, it is that the deep-learning algorithms behind AIs spit out answers that amount to a “what” rather than a “why”, which makes them about as useful for a theorist as saying the answer to the question of life, the universe and everything is 42.
The search continues for signs of ancient alien life on the red planet.
NASA’s Perseverance mission on Mars has performed several world firsts, including the first controlled flight on another planet and the first extraction of oxygen from the Martian atmosphere.
New Mars findings point to ancient alien life.
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 species) fine-tuning the conditions.

SpaceX sent one of its first-stage boosters skyward for the 11th time on Tuesday evening. However, unlike its 10 previous flights, this time it didn’t return.
The mission launched from Space Launch Complex 40 (SLC-40) at Cape Canaveral Space Force Station in Florida at 9:57 p.m. ET, lighting up the night sky as the Falcon 9 rocket roared toward space.
Thirty-five minutes after leaving the launchpad, the Falcon 9’s second stage deployed a communications satellite to a geosynchronous transfer orbit for French satellite operator Eutelsat.

It’s frigid and strange and orbits its home planet backward.
But Enceladus isn’t the only location in our solar system with active geysers, as another small moon near the edge of the solar system shares similar characteristics, as well. This is Neptune’s largest moon, Triton, which has been visited only once by NASA’s Voyager 2 in 1989. But are Triton’s geysers the only characteristics that make it a good target for astrobiology and finding life beyond Earth?
“Triton may be an ‘ocean world’, a moon that has a solid ice crust over a liquid water subsurface ocean,” said Candice Hansen-Koharchek, a planetary scientist who was a Voyager Imaging Team Assistant Experiment Representative during the Voyager missions. “If that is the case, and if we are able someday to reach that ocean and find life, that would extend the habitable zone to the Kuiper Belt, not just the inner solar system. That has profound implications, both in our solar system and at exoplanets.”
