IBYXO.COM - 4 dimensions, there are many explanations about 4 dimensions but let me bring you to understand and explore it. Have you ever thought that 4 dimensions exist? Yep, 4 dimensions is a continuation of 3 dimensions mathematically, and also describes a lot of beauty in its shape. In Mathematics In mathematics, a 4-dimensional space refers to a space that has four dimensions, which are typically represented as x, y, z, and w. This is different from the familiar 3-dimensional space that we live in, which has three dimensions represented as x, y, and z. To understand 4-dimensional space, we can start by visualizing a point in 3-dimensional space. A point is represented by three coordinates, (x, y, z), which determine its position in space. Similarly, a point in 4-dimensional space is represented by four coordinates, (x, y, z, w). These four coordinates determine the point's position in a space that has four independent directions. One way to visualize a 4-dimensional space is t...

IBYXO - Have you ever thought what a black hole is, is it a large object in outer space that is only black? Of course not, let me explain and I'll take you around outer space there.  Before that, The concept of a black hole was first proposed in the late 18th century by the English astronomer John Michell. Michell suggested that there could be stars so massive and so compact that their gravity would be strong enough to prevent light from escaping, making them invisible. However, the idea was largely forgotten until the 20th century. In the 1960s, scientists began to develop a more complete understanding of the physics of black holes, and they became a topic of intensive research in the field of astrophysics. In 1964, the physicist Roger Penrose showed mathematically that the collapse of a massive star would inevitably result in the formation of a singularity, a point of infinite density at the center of a black hole. This work provided strong evidence for the existence of black hol...
