Summary
This study challenges the Hubble law, finding that a square redshift-distance relationship is statistically superior to the linear model. The linear model lacks objective statistical support when analyzed rigorously.
Area of Science:
- Cosmology
- Astrophysics
- Statistical Astronomy
Background:
- The Hubble law describes the universe's expansion using a linear redshift-distance relationship.
- Observational biases, such as redshift-magnitude cutoff, can affect cosmological measurements.
- Theoretical cosmology provides frameworks for understanding cosmic expansion and distances.
Purpose of the Study:
- To apply an optimal nonparametric technique to eliminate observation cutoff bias.
- To test the validity of linear versus square redshift-distance laws in galaxy samples.
- To statistically evaluate the foundation of the Hubble law.
Main Methods:
- Application of an optimal nonparametric technique for bias elimination.
- Analysis of redshift-magnitude and redshift-angular diameter relationships.
- Nonparametric crosstesting of linear and square redshift-distance law hypotheses using data and simulations.
Main Results:
- Estimates strongly favored a square redshift-distance law over a linear one.
- The square law accurately predicted the statistical outcomes of the linear law analyses.
- The linear law failed to predict the observed good fit of the square law.
Conclusions:
- The Hubble law, in its linear form, appears to lack an objective statistical foundation.
- The square redshift-distance law demonstrates superior statistical performance.
- Further validation of ancillary hypotheses is needed to support the linear model.

Kepler's Third Law of Planetary Motion
In the early 17th century, German astronomer and mathematician Johannes Kepler postulated three laws for the motion of planets in the solar system. In 1909, he formulated his first two laws based on the observations of his forebears, Nikolaus Copernicus and Tycho Brahe. However, in 1918, he published his third law of planetary motion, which gives a precise mathematical relationship between a planet's average distance from the Sun and the amount of time it takes to revolve around the Sun. It...
Detection of Black Holes
Although black holes were theoretically postulated in the 1920s, they remained outside the domain of observational astronomy until the 1970s.
Their closest cousins are neutron stars, which are composed almost entirely of neutrons packed against each other, making them extremely dense. A neutron star has the same mass as the Sun but its diameter is only a few kilometers. Therefore, the escape velocity from their surface is close to the speed of light.

Space-Time Curvature and the General Theory of Relativity
In 1905, Albert Einstein published his special theory of relativity. According to this theory, no matter in the universe can attain a speed greater than the speed of light in a vacuum, which thus serves as the speed limit of the universe.
This has been verified in many experiments. However, space and time are no longer absolute. Two observers moving relative to one another do not agree on the length of objects or the passage of time. The mechanics of objects based on Newton's laws of motion,...

Chebyshev's Theorem to Interpret Standard Deviation
Chebyshev’s theorem, also known as Chebyshev’s Inequality, states that the proportion of values of a dataset for K standard deviation is calculated using the equation:
Testing a Claim about Standard Deviation
A complete procedure to test a claim about population standard deviation or population variance is explained here.
The hypothesis testing for the claim of population standard deviation (or variance) requires the data and samples to be random and unbiased. The population distribution also must be normal. There is no specific requirement on the sample size as the estimation is based on the chi-square distribution.
As a first step, the hypothesis (null and alternative) concerning the claim about...

Wald-Wolfowitz Runs Test II
The Wald-Wolfowitz runs test, commonly referred to as the runs test, is a nonparametric test used to assess the randomness of ordered data. The test evaluates the number of runs, which are consecutive sequences of similar elements within the data. If the number of runs is significantly higher or lower than expected, the data is considered non-random, indicating a detectable pattern or structure.
For binary data, runs are identified using symbols such as + and −, or equivalently, 1s and 0s. In...
