Zero-point energy of vacuum fluctuation as a candidate for dark energy versus a new conjecture of antigravity based on the modified Einstein field equation in general relativity
Guang-jiong Ni
In order to clarify why the zero-point energy associated with the vacuum fluctuations cannot be a candidate for the dark energy in the universe, a comparison with the Casimir effec…
de'Broglie's paradox, relativistic Doppler effect, and the derivation of mass-energy relation in special relativity
Guang-jiong Ni
Three related topics are discussed to show the "simplicity, harmony and beauty" of the theory of special relativity (SR): (1) How can de'Broglie discover his famous relation betwee…
Principle of relativity in physics and in epistemology
Guang-jiong Ni
The conceptual evolution of principle of relativity in the theory of special relativity is discussed in detail. It is intimately related to a series of difficulties in quantum mech…
Cosmic Ray Spectrum and Tachyonic Neutrino
Guang-Jiong Ni
In the cosmic ray spectrum, there are two knees (abrupt changes of slopes) located around the energies eV and eV respectively. Based on the pioneerin…
A new insight into the negative-mass paradox of gravity and the accelerating universe
Guang-Jiong Ni
The discovery of acceleration of the universe expansion in recent astrophysics research prompts the author to propose that the Newton's gravitation law can be generalized to accomm…
