Ever wondered what the universe is made up of? First, you need to understand that the substance of the known universe is classified as matter. And the known universe itself only represents 5 percent of the entire universe. The remaining 95 percent is made of things we haven’t fully understood yet — dark matter and ...
A team of scientists, including two physicists at the University of Sussex, has found a way to circumvent a 178-year-old theory, which means they can effectively cancel magnetic fields at a distance. They are the first to be able to do so in a way that has practical benefits. The work is hoped to have ...
Time travel has always fascinated people. The idea that you can travel to the future to know what will happen or back to the past and influence the present is something that definitely piques interest. However, is time travel really possible according to physics? Theoretically, it does seem so. Traveling through time Just so you ...
The ancient Greek philosopher Plato believed that the universe consisted of five fundamental elements — air, fire, water, cosmos (or aether), and earth. According to his theory, each of these elements had its own geometric shape, with earth particles being cubes. Science now considers atoms to be the building blocks of matter. But according to ...
Gravity is one of the fundamental concepts in physics. Gravity is used to explain the creation and sustenance of the universe, from the smallest particle to the biggest of galaxies. In 2009, a physics professor named Erik Verlinde proposed something radical that shook the foundations of physics. He theorized that gravity does not actually exist ...
Dark matter has been a mystery to scientists for a long time. A team of physicists from Vanderbilt University and Case Western Reserve University asked themselves a rather interesting question — “Has dark matter killed anyone?” Dark matter and death Macro dark matter particles are known to elastically scatter regular matter across a wide geometric ...
The Higgs field is like an endless ocean through which all matter swims. Some particles are like sponges and sop up mass as they lumber along, while others are as sprightly as tiny minnows and dart right through. The Higgs theory is a beautifully simple explanation as to why some particles are massive while others ...
A Columbia University-led team of astrophysicists has discovered a dozen black holes gathered around Sagittarius A* (Sgr A*), the supermassive black hole in the center of the Milky Way Galaxy. The finding, which has been published in Nature, is the first to support a decades-old prediction, opening up myriad opportunities to better understand the universe. Astrophysicist Chuck Hailey, ...
