Have you ever felt like the world around you isn’t exactly… “real”? Modern physics is starting to suggest something incredible: The universe isn’t made of atoms, energy, or particles. It is made of Information. In this video, we explore the radical “It from Bit” theory and the Holographic Principle. From the mysterious paradoxes of Black Holes and Hawking Radiation to the way quantum entanglement might actually create the fabric of space and time, we dive deep into the mind-bending reality of quantum mechanics. In this video, we cover: Why Stephen Hawking conceded the Black Hole Information Paradox. The Ryu-Takayanagi formula: How entanglement builds geometry. Why 3D space might just be a 2D holographic projection. The “It from Bit” philosophy by John Wheeler. How consciousness relates to Integrated Information Theory (IIT). If reality is just a pattern of qubits in a vast Hilbert space, what does that make us? Join us as we deconstruct the material world and look at the “source code” of the universe. #QuantumPhysics #HolographicUniverse #ItFromBit #TheoreticalPhysics #ScienceDocumentary #SpaceTime #quantuminformation

BREAKING: A Dark Mysterious Force Just Ripped Across the Milky Way
A viral post claimed that a mysterious force passed through the Milky Way without light or warning. But what are astronomers actually observing? In this video, we break down the real science behind high-velocity gas clouds, dark matter halos, and how our galaxy continues to evolve.

Finally Released! The James Webb Telescope Has Found The Object That Holds Our Universe Together.
Containing nearly 800,000 galaxies, this image from NASA’s James Webb Space Telescope is overlaid with a map of dark matter, represented in blue. Researchers used Webb data to find the invisible substance via its gravitational influence on regular matter.
You see, Scientists using data from NASA’s James Webb Space Telescope have made one of the most detailed, high-resolution maps of dark matter ever produced. It shows how the invisible, ghostly material overlaps and intertwines with “regular” matter, the stuff that makes up stars, galaxies, and everything we can see.
Published Monday, Jan. 26, in Nature Astronomy, the map builds on previous research to provide additional confirmation and new details about how dark matter has shaped the universe on the largest scales — galaxy clusters millions of light-years across — that ultimately give rise to galaxies, stars, and planets like Earth.

Comments on the Hartle-Hawking state and observers — Ying Zhao
Workshop on quantum aspects of black holes and spacetime.
Topic: Comments on the Hartle-Hawking state and observers.
Speaker: Ying Zhao.
Affiliation: Massachusetts Institute of Technology.
Date: December 3, 2025
Wolfensohn Hall.
It was argued that any fixed holographic theory contains only one closed universe state and hence fails to give semi-classical physics. It was proposed that this problem can be resolved by including a classical observer living inside the universe. Earlier works focused on closed universes connected with asymptotic Euclidean boundaries. In this talk we examine the case of Hartle-Hawking state where the dominant Euclidean topology is a sphere. We show that different features emerge. We comment on the potential implications for the understanding of de Sitter space. Based on work with Daniel Harlow.
UNBELIEVABLE! JWST Just Found the Earliest Supernova in History
Astronomers using the James Webb Space Telescope have confirmed the earliest supernova ever observed, linked to the gamma-ray burst GRB 250314A. The explosion occurred when the universe was just 730 million years old and looks surprisingly similar to modern supernovae, offering new insight into how the first massive stars lived and died.

Physicists develop new method to measure universe’s expansion rate
We have known for several decades that the universe is expanding. Scientists use multiple techniques to measure the present-day expansion rate of the universe, known as the Hubble constant. These methods are internally consistent and based on the same physics, so all observed values of the Hubble constant should agree. But those that come from early-universe datasets disagree with those that come from late-universe datasets. This problem is known as the Hubble tension and is considered to be one of the most significant open questions in cosmology.
Now a team of astrophysicists, cosmologists, and physicists at The Grainger College of Engineering at the University of Illinois Urbana-Champaign and at the University of Chicago has developed a novel way to compute the Hubble constant using gravitational waves—tiny ripples in the spacetime fabric. The researchers were able to improve upon the accuracy of prior gravitational-wave methods of measuring the Hubble constant. As our capability to observe gravitational waves improves in the future, this new method can be used to make even more accurate measurements of the Hubble constant, bringing scientists closer to resolving the Hubble tension.
Illinois Physics Professor Nicolás Yunes said, “This result is very significant—it’s important to obtain an independent measurement of the Hubble constant to resolve the current Hubble tension. Our method is an innovative way to enhance the accuracy of Hubble constant inferences using gravitational waves.” Yunes is the founding director of the Illinois Center for Advanced Studies of the Universe (ICASU) on the Urbana campus.
