[Stock Market] Google’s AI Power Play: Meta Eyes Chips as Salesforce CEO Hails Gemini
Salesforce CEO Marc Benioff publicly praised Google’s new Gemini 3 AI model, saying it has leapfrogged ChatGPT. He emphasized this shift as significant since he had relied on ChatGPT daily for years. His reaction (“Holy s**t”) highlights the surprise and weight of his endorsement.
Benioff’s opinion carries influence because he is a prominent and outspoken tech leader. He has described AI as the most important technology of his lifetime, so his endorsement signals a major shift in enterprise attention toward Gemini.
Google and Meta are currently in discussions regarding a multi-billion-dollar deal involving Google's AI chips. This deal could significantly reshape the competitive landscape in the AI chip market, with Meta considering both renting and purchasing Google's Tensor Processing Units (TPUs) starting in 2027. The agreement aims to enhance Meta's AI infrastructure and could potentially allow Google to capture a substantial portion of Nvidia's revenue, which is currently a major player in the market.

[Space] About 3I/ATLAS' Mass Loss of 5 Billion Tons a Month
An article has reported that Harvard astrophysicist Avi Loeb suggested comet 3I/ATLAS is losing about 5 billion tons of mass per month, possibly due to “technological thrusters pointing toward the Sun.” NASA quickly countered, stating it is a natural interstellar comet. The debate has sparked scientific and public controversy, with NASA confirming the comet shows non‑gravitational acceleration but attributing it to natural cometary processes/
Background of 3I/ATLAS
Discovery: 3I/ATLAS was first detected in July 2025 by the ATLAS telescope in Chile.
Nature: It is the third confirmed interstellar object to enter our solar system, after ʻOumuamua (2017) and 2I/Borisov (2019).
Trajectory: Its orbit is hyperbolic, meaning it is not bound to the Sun and will eventually leave the solar system.
Speed: At perihelion (closest approach to the Sun), it reached speeds of 153,000 mph (68 km/s).
Scientific Value: Offers a rare chance to study material formed around another star system ~7 billion years ago.
Images: NASA and international observatories have released multiple images showing its coma and tail, confirming cometary behavior.
Detailed background on Wikipedia.
Observations & Speculation About “Spaceship” Theories
While mainstream science identifies 3I/ATLAS as a comet, some unusual features have fueled speculation:
Avi Loeb’s Claim: Suggested its mass loss and trajectory could be consistent with artificial propulsion.
NASA’s Response: Officials firmly reject alien spacecraft theories, stating “it looks and behaves like a comet”.
Public Speculation: Online discussions compared it to ʻOumuamua, with some conspiracy theories suggesting it might be a probe.
Scientific Debate: Physicist Michio Kaku dismissed the alien hypothesis, calling it a “cosmic relic” rather than engineered technology.
Unusual Tail: Observations show a complex, changing tail structure, which some enthusiasts interpret as evidence of artificiality, though astronomers attribute it to natural outgassing.
Academic Papers: A few speculative studies (e.g., Loeb et al. draft, arXiv preprint) explore the possibility of technological origins, but these remain fringe ideas.

[Earth] South Atlantic Anomaly and Huge Structures inside Earth Related to the Life Origin?
Here is a Summary of Two Interesting Articles related to Earth. The second one is important for our future.
Article 1: Scientists Say Huge Structures Inside Earth Are Related to the Origin of Life
Huge Structures Inside Earth
Scientists have identified two continent-sized dense rock structures at the boundary of Earth’s mantle and core, located beneath Africa and the Pacific Ocean.
These formations, called large-low shear velocity provinces (LLSVPs) and ultra-low velocity zones, disrupt seismic waves and suggest unusual composition.
New Theory
A team led by Yoshinori Miyazaki (Rutgers University) proposes that these structures formed from silicon and magnesium leaking from Earth’s core billions of years ago.
This leakage may have “contaminated” a basal magma ocean, preventing uniform solidification and creating the lumpy mantle composition.
Implications for Earth’s Evolution
This process could have helped Earth cool sufficiently, triggering volcanic activity and shaping the atmosphere.
It may explain why Earth developed a stable, habitable environment, while Venus and Mars became inhospitable.
Scientific Significance
These structures are described as “fingerprints of Earth’s earliest history.”
Understanding them could provide insight into planetary formation and why Earth is uniquely suited for life.
Article 2: This Strange Anomaly is Expanding, And NASA is Tracking It Over the South Atlantic
What the South Atlantic Anomaly (SAA) Is
The South Atlantic Anomaly (SAA) is a weak spot in Earth’s magnetic field, located between South America and southwest Africa.
It appears as a “dent” in the magnetic shield, allowing more high-energy solar particles to reach satellites.
Expansion and Division
The anomaly has been expanding steadily since its discovery, growing by nearly half the size of continental Europe since 2014.
In 2020, scientists observed that the anomaly is splitting into two distinct regions, with different behaviors near Africa and South America.
Risks to Satellites
Satellites passing through the SAA are vulnerable to glitches or malfunctions caused by solar particles.
Operators often shut down sensitive systems temporarily to prevent data loss or damage.
NASA has already observed real-time disruptions linked to the anomaly.
Possible Causes
The anomaly may be influenced by a massive dense rock structure beneath Africa called the African Large Low Shear Velocity Province.
This disrupts the magnetic field generated by Earth’s molten iron core.
NASA geophysicists note that a localized reversed polarity field is growing in the region, weakening the overall magnetic strength.
Scientific Importance
The SAA provides clues about how Earth’s magnetic field evolves.
Ongoing monitoring is crucial for protecting space missions and understanding planetary dynamics.
