ABSTRACT: The current model of a Schwarzschild black hole is analyzed in terms of consistency of its basic properties. The concept of gravitational singularity involves mathematical and physical ...

Most people are familiar with the concept of a black hole: a “hole” or extreme warping in space and time that endlessly devours any matter unfortunate enough to venture close to it. Even light can’t ...

To Earthlings gazing into space, our solar system appears to be surrounded by billions of stars in the Milky Way. But if we look even further out, would it be possible to find evidence that we were in ...

It is demonstrated that the Kruskal-Szekeres coordinates are extrinsic coordinates of the Schwarzschild metric while the Schwarzschild coordinates are intrinsic. The is the reason the two coordinate ...

In this paper, we make an analogy of the interior Schwarzschild metric from transformation optics (we call the method transformation cosmology). It is shown that a simple refractive index profile is ...

According to a new theory, the Bifrost used by Marvel superhero Thor and his fellow Asgardian people was not completely fiction. The Bifrost was the fictional term used in the movie to describe what ...
