Hyperluminal Space Travel

Authors: Clark M. Thomas
Comments: 10 Pages.

Hyperluminal space travel is big in popular sciencefiction and fantasy. How does it rate among realrocket scientists and astrophysicists? The answerto this basic question spans more than physics, andgoes into concerns relating to our brief reign as thecurrent hyperkeystone species on Earth.

Fibonacci Numbers and Gravitational Radiation

Authors: Alberto Coe
Comments: 10 Pages.

In this short article We have done an arithmetic approximation that analyzes the currentformalism of the phenomenon of gravitationalwaves.To do this we have resorted to the use of thewell known Fibonacci series of natural numbers and the logarithmicspiral associated with the sequence of such numbers.

Simplified Trigonometric Method for Distance Measurements

This study develops a mathematical approach to estimate the distance of a celestial object from an observer using angular measurements. The method involves capturing the subtended angles of the object from two distinct positions along a known baseline distance and employs trigonometric relationships to derive a formula for calculating the distance. Using a camera, the angular size of the object is determined based on its apparent size on the camera's sensor. The calculated angles are substituted into the derived formula to compute the distance. Validation of the formula was performed by calculating the Moon's distance from Earth using angular measurements taken at two locations separated by 100 km. The computed distance of approximately 376,742 km closely aligns with the Moon's average distance from Earth, confirming the accuracy of the method. This straightforward approach demonstrates potential utility for amateur astronomers and educators, offering an accessible tool for celestial distance measurement using basic geometry.

Time-Dilation for Supernova in the Case of Tired Light Hypothesis

Authors: Dmitriy S. Tipikin
Comments: 7 Pages.

One of the most important confirmation of the Big Bang theory was the discovery of the time broadening of the light curve of the far supernovas (supernovas 1A, standard candles, at the distances around Z=1). From straightforward consideration in the complete absence of light scattering it can not be explained in any other way but by Doppler-like effect which in this case called time dilation and seemingly confirming the Big Bang. However, the hypothesis of tired light [1] also allows the light being diffusion-like scattered on travel from supernova thus allowing change in distance traveled and allowing corresponding time broadening of the light curve (the fastest photons goes straight path, later arrived those which due to multiple scattering — diffusion-like in perpendicular direction — first traveled away from direct line, than returned back, possible many times and thus got a big enough increase in distance to generate perceptible — few days- delays at arrival). Problem with this mechanism is that gives smaller time delays compare to time dilation directly observed [1]. The gravitational microlensing may be involved and due to additional change of distance, Shapiro effect and brightening some parts of the image of supernova (3 separate effects) will make the light curves broader and thus explaining the time dilation observed.
