In the vast world of space-time theories, scientists are diving deep into something called energy conditions. These are like rules that energy in the universe must follow. In particular, they are looking at a special kind of theory known as generalized teleparallel gravity. This theory is not just one thing. It has different versions. One is pure F(T), another mixes...
In the vast theater of the cosmos, scientists have long been fascinated by the idea of a brane-world universe. This concept suggests that our familiar 4-dimensional world is like a stage, embedded within a larger 5-dimensional space known as the bulk. To make sense of this complex scenario, researchers have turned to a method called the Arnowitt-Deser-Misner decompos...
Neutrinos are everywhere, yet we know so little about them. These tiny particles zip through everything, including our bodies, without a trace. They come in three types and can switch between them as they travel. But what makes them so special? They might hold the key to some of the universe's biggest secrets, like why matter exists over antimatter and what dark matt...
In the vast expanse of space, a black hole named RACS J0320-35 is causing quite a stir. This cosmic giant, born a mere 920 million years after the Big Bang, is growing at an astonishing rate. It's not just any growth spurt; this black hole is feasting on matter at 2. 4 times the speed that scientists thought was possible. This discovery is a big deal because it chall...
Scientists have made a bold claim: Earth and the Milky Way might be sitting in a huge, empty space. This isn't just any empty space—it's a void that's 20% less dense than the rest of the universe. Imagine a bubble 2 billion light-years wide, with our galaxy floating in the middle. This idea comes from studying the echoes of the Big Bang, which are like cosmic fingerp...
The universe is full of mysteries, and one of the biggest is dark matter. Scientists have been trying to figure out what it is for a long time. Recently, a particle called the axion has become a hot topic. It was first thought of to solve problems with the strong nuclear force, but now it's being considered as a possible explanation for dark matter. But why do so ma...
The universe is full of mysteries, and one of the biggest is dark energy. For years, scientists have believed that dark energy is a constant force driving the universe's expansion. But new data from the Dark Energy Spectroscopic Instrument (DESI) suggests that dark energy might be weakening over time. This is a big deal because it challenges the standard model of co...
The universe's earliest moments have been captured in stunning detail. A global team of scientists has unveiled new images that provide an unprecedented look at the cosmos in its infancy. These images offer a glimpse into the universe's early days, around 380, 000 years after its birth. The universe is roughly 13 billion years old, so these images are like seeing a b...
A recent discovery has left scientists scratching their heads. While looking at images from NASA's James Webb Space Telescope, a researcher found something odd. Out of 263 galaxies, two-thirds were spinning clockwise, and only one-third were spinning counterclockwise. This isn't what scientists expected. They thought galaxies would be evenly split between the two di...
The North Atlantic Treaty Organization (NATO) Advanced Study Institute (ASI) kicked off with a provocative lecture. It sparked discussions on the current debates, the future potential, and the societal impact of cosmology over the next decade and beyond. Cosmologists are eagerly anticipating what discoveries await, but they're also aware of the challenges they might ...
