💫 Scientists Discover the Largest Structure in the Universe

Astronomers have uncovered a colossal cosmic structure named "Quipu," stretching an incredible 1.3 billion light-years across—more than 13,000 times the size of our Milky Way! This massive formation holds the equivalent of 200 quadrillion suns in mass. Its discovery challenges what we know about the universe, offering fresh clues about galaxy formation, dark matter, and the evolution of large-scale cosmic architecture.

🤔 Microsoft Study: AI May Harm Critical Thinking

A study by Microsoft and Carnegie Mellon found that heavy reliance on generative AI can reduce critical thinking among workers. Surveying 319 workers and analyzing 936 AI use cases, researchers observed that many accept AI outputs without proper evaluation, mistaking minor edits for critical thought.

Key insights:

➡️ High trust in AI lowers critical thinking effort.

➡️ Strong self-confidence improves critical thinking and evaluation of AI outputs.

The findings highlight the need to balance AI use with independent problem-solving skills.

⏳ Time May Flow Both Ways in Quantum Systems

Physicists at the University of Surrey have uncovered fascinating evidence that challenges the traditional "one-way street" view of time. Their research suggests that, in certain quantum systems, time might flow forward or backward — a concept known as quantum time symmetry.

Here’s what they found:

➡️ Some quantum systems follow equations that work the same in both time directions.

➡️ This opposes the classical idea of time always moving from past to future.

➡️ It hints at the possibility of opposing arrows of time within quantum mechanics.

This discovery could reshape how we understand time and its connection to the quantum and macroscopic worlds. Time travel, anyone?
