NIST considers the mystery of the gravitational constant

A wide shot shows two researchers on either side of a scientific device made of metal cylinders, staring intently at it.

Stephen Hawking’s infamous black hole paradox may be solved if the universe has seven dimensions

Diagram of a 7-dimensional twisted knot. It is theorized that it exerts a repulsive force that prevents black holes from evaporating.

New theoretical research suggests that black hole While it may not completely evaporate, this contradicts Stephen Hawking’s infamous theory and appears to violate the fundamental laws of the universe. quantum mechanics. Instead, black holes may leave behind small, stable remnants that store all the information they once consumed, the study suggests. But there’s a twist, … Read more

Black hole jet measured for the first time, comparable in power to 10,000 suns

Black hole jet measured for the first time, comparable in power to 10,000 suns

Researchers have taken a major step toward understanding how black holes affect the universe by directly measuring the power of their jets. A team led by Curtin University used a network of radio telescopes spread across the world to take detailed images that reveal just how energetic these jets are. The discovery supports long-standing theories … Read more

Research shows that dark matter does not exist and the universe is 27 billion years old

earth snap

At first glance, the universe seems simple: stars, gas, dust, and gravity holding it all together. Then, when you look more carefully, you realize that nothing could be further from the truth. For decades, standard imagery has told us that most of what is out there is not what we can see. It is a … Read more

Physicists witness dark needle traveling faster than the speed of light without violating the theory of relativity

An illustration shows swirling orange and blue holes against a glowing wall to the left.

Researchers have detected for the first time that voids in the sky are moving faster than people. speed of light And they broke the speed limit of the universe without breaking the theory of relativity. Recent studies have shown void acceleration. The researchers used recent advances in ultrafast electron microscopy to measure the voids of … Read more
