Physics has always been about figuring out the structure of the world, and the same can be said about our brains. However, physics often comes to conclusions that conflict with concepts fundamental to our minds, such as the realness 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…
Time is a fundamental concept that is difficult to define precisely. In physics, time is often defined as a dimension in which events occur in a sequence. Time is considered to be continuous and to flow at a constant rate,…
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…
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…
How many multiverses are there? The universe we can observe is not unique, but there are billions of others. In other words, the universe would be part of a larger “multiverse.” As a result, some well-known scientists have spoken of…
Real Star Trek Impulse Engine: Using conventional fuel rockets, it would take 16,000 years to reach the nearest star. Interstellar travel cannot be achieved with conventional rockets. While space may be the final frontier, rocket fuel won’t get us very…
