In 2024, two international research teams announced the possibility that dark energy is a function of time. 1. In January 2024, the Dark Energy Survey team, an international collaborative research team of more than 400 scientists, announced the results of an analysis of 1,499 supernovae. This...

Regarding the center of the universe, there are differences in the coordinate system used between physicists and the public. When physicists describe the universe, they describe it in 4-dimensional space including the dimension of curvature, or 4-dimensional spacetime including the dimension of...

Most of the people who read this article will have a strong objection and antipathy to the negative mass (density), but~ 1.The first result of Friedmann's equation for accelerated expansion was negative mass density Nobel lecture by Adam Riess : The official website of the Nobel Prize Refer to...

The observable universe exists inside a black hole created by the total mass present in the observable universe. 1.Black hole cosmology If we find the size at which the mass distribution with the average mass density of the present universe forms a black hole. R=2GM/c^2...

*Background description Why do we need gravitational potential energy or gravitational field energy? 1) The fundamental principle of general relativity states that “all energy is a source of gravity”. However, the field equation created by Einstein did not fully realize this principle The...

The source of dark energy is gravitational self-energy or the gravitational action of the gravitational field! 1. Gravitational potential energy is negative energy 1) Alan Guth said 2) Stephen Hawking also said Both said that gravitational potential energy is negative energy and is the true...
