For the first time, astronomers have peered inside a black hole and made a startling discovery about its contents. Using advanced imaging techniques, researchers were able to see what lies in the depths of a black hole: powerful jets of…
Learn about the journey of light in the universe, from its creation during the formation of the first hydrogen atom, through the Dark Ages, the formation of stars and galaxies, and its collision with metal in a man-made telescope near…
The lifetime of a star depends on its mass, with more massive stars having shorter lifetimes and less massive stars having longer lifetimes. The most massive stars can burn through their fuel quickly, ending their stellar evolution in a spectacular…
Dark matter is frustrating because it’s everywhere, but we don’t know what it’s made of. There is plenty of evidence for dark matter, including the rotation curves of galaxies and the cosmic microwave background, but attempts to explain it away…
The Theory of Everything seeks to unify all fundamental forces and particles. It unites quantum physics and general relativity, two of the most widely accepted scientific theories. The Theory of Everything helps scientists understand the cosmos and anticipate the behavior…
Studies have recently suggested that the core of the Earth may have stopped spinning faster than the rest of the planet at some point in the last decade. Located thousands of kilometers below the surface, this inner core could possibly…
It’s true that not every supernova is the same. What follows is a synopsis of the various types of exploding stars. What is the most dangerous supernova? Type I and Type II are the two main groups of supernovae based…
What do you think about the idea of time? Is it real, or is it an illusion? I think the question that needs to be asked is, how can you be certain that time is real? What does it mean…
Black holes exist in the real world but are also a theoretical nightmare. To understand their paradoxical nature, imagine each black hole as a swarm of imaginary black holes connected by wormholes. And you thought the universe couldn’t possibly get…
A cosmic horizon limits the observable universe. Beyond the cosmic horizon, there are other galaxies, but their light has not yet had time to reach us. This is because space and time were created in the Big Bang about 14…
