🚨: New evidence reveals Earth could be trapped in a massive cosmic void in space — 2 billion light-years across Image
Scientists suggest Earth lies inside a massive cosmic void about 1 billion light-years wide, where galaxy density is around 20% lower than average. This finding is based on patterns from ancient sound waves called baryon acoustic oscillations (BAOs).
This void could explain the “Hubble tension”—why the universe’s local expansion rate appears faster than distant measurements. Being in a low-density region might distort our view of how fast the universe is expanding around us.
BAOs act like a cosmic ruler. When scientists included a local void in their models, the data fit far better than with a uniform universe. This supports earlier findings of a galaxy shortage in our region, known as the KBC Void.
If confirmed, the void theory could solve cosmic puzzles without changing the Big Bang model. It suggests our location affects key measurements, and researchers plan further studies to test the idea using galaxy data and alternative methods.

🚨: Our universe might be trapped inside of a black hole. This James Webb Space Telescope discovery might blow your mind Image
The James Webb Space Telescope found that early galaxies don't spin randomly. Out of 263 studied, 62% spun clockwise. This imbalance challenges the idea of a symmetrical universe and hints at deeper cosmic forces or structures at play.
Such a spin preference suggests the universe may have a large-scale direction or rotation. This goes against the long-held belief that the universe is isotropic—meaning it looks the same in every direction, with no preferred spin or structure.

🚨: Scientists create matter from pure light, proving Einstein's 90-years old theory E=mc², right in the lab! Image
Physicists created matter from pure light — proving Einstein’s 90-year-old prediction
In one of the most extreme experiments in modern physics, scientists at SLAC National Accelerator Laboratory have turned light into matter — literally creating particles from pure energy using two beams of gamma rays. It’s a breakthrough that proves a key aspect of Einstein’s E=mc² in its rawest form.
The experiment used the powerful Linac Coherent Light Source (LCLS), where laser beams were focused onto gold foils to create short bursts of high-energy photons. When these photons collided in a vacuum chamber, they produced electron-positron pairs — particles with mass, born from nothing but light.

🚨: Astronomers baffled by Black Hole burping out star three years after devouring it. 'No one has ever seen anything like this before' Image
In 2018, astronomers observed a star being torn apart by a supermassive black hole in an event named AT2018hyz. This tidal disruption shredded the star into hot plasma, sending it spiraling around the black hole in a dramatic flare. Unexpectedly, nothing more was seen—until years later.
In late 2021, a New Mexico radio telescope detected a sudden burst of radio waves from the same black hole, revealing it had belatedly expelled stellar debris at up to half the speed of light. Most tidal disruption outflows coincide with the initial flare, making this delayed “burp” entirely unprecedented.

🚨: Scientists say they’ve found ‘strongest evidence to date’ of life beyond our solar system illustration (not real image of K2-18B)
This could change everything.

In a groundbreaking discovery, scientists using the James Webb Space Telescope have found what may be the strongest evidence yet of life beyond Earth.
The target is K2-18 b, an exoplanet 124 light-years away, orbiting in the habitable zone of its star. Classified as a “Hycean world”—a planet with a hydrogen-rich atmosphere and a vast liquid ocean—K2-18 b now shows signs of something extraordinary: atmospheric chemicals that, on Earth, are primarily produced by life.

🚨: Groundbreaking James Webb ST observations indicate we might be inside a black hole! Image
A team of scientists is proposing a bold alternative to the Big Bang theory, suggesting that our universe may have formed inside a colossal black hole residing in a larger, parent universe.
Gaztañaga, professor at the University of Portsmouth, says he and his colleagues wondered if a simpler explanation might suffice. "[Our study] began with a simple but profound question: Why is the expansion of the universe accelerating?" he said.

NEWS🚨: Scientists just captured the first direct image of the cosmic web — the mysterious structure that holds the universe together Image
Astronomers have captured the first-ever direct image of a strand in the cosmic web.

Researchers caught the slender strand linking galaxies, and they traced it across roughly 3 million light-years.
The cosmic web is a vast network of hydrogen filaments that threads through space and underpins the structure of the universe.

Using the powerful MUSE instrument on the European Southern Observatory’s Very Large Telescope, researchers observed a glowing filament stretching three million light-years between two ancient quasars—bright beacons from a time when the universe was just 2 billion years old.
