Spiral Galaxy Rotation Curves Without Dark Matter or MOND -- Two Conjectures
Tarun Biswas
Usual explanations of spiral galaxy rotation curves assume circular orbits of stars. The consequences of giving up this assumption are investigated here. In particular, hyperbolic…
Freely Falling Finite Frames Near a Black Hole
Tarun Biswas
It is well-known that the Riemann curvature tensor has no discontinuity at the black hole horizon. It is also well-known that a freely falling observer takes finite time to reach t…
Through the Black Hole -- On Not Breaking Time Reversal Symmetry
Tarun Biswas
It is well-known that a particle falling into a black hole will definitely reach the center in finite proper time if it enters the sphere of radius where is the…
Another Alternative to the Higgs Mechanism
Tarun Biswas
The Higgs mechanism is designed to generate mass for massless particles. The mass comes from the interaction of observed particles with an external field -- the Higgs field. In the…
Physical Interpretation of Coordinates for the Schwarzschild Metric
Tarun Biswas
Since its first introduction, the Schwarzschild metric has been written in various coordinate systems. This has been done primarily to understand the nature of the coordinate singu…
Nonunitary Interaction, Adiabatic Condition, Haag's Theorem and Renormalization
Tarun Biswas
Haag's theorem has shown that the transformation between interacting and free field operators in a reasonable quantum field theory cannot be unitary. Here, the original requirement…
