Introduction:

The realm of special relativity has revolutionized our understanding of the fundamental interplay between mass and energy. Central to this paradigm is the concept of relativistic mass (m′), a dynamic quantity that unveils itself as an equivalent to an effective mass (mᵉᶠᶠ). In this exploration, we embark on a journey to elucidate the intricate relationship between m′ and energy within the framework of special relativity.

Distinguishing m′ from its counterpart, the rest mass (m₀), we emphasize its non-invariant nature and delve into the energetic implications encapsulated in the equation m′ = m₀/√{1 - (v²/c²)} - m₀.

Building upon this foundation, we introduce the notion of m′ as an equivalent to an effective mass (mᵉᶠᶠ), transcending the conventional boundaries of rest mass considerations. As we unravel the implications of m′ in energetic terms, we discern its unit as joules (J), echoing the inherent connection between relativistic mass and energy.

A practical example, featuring an "effective mass" of 0.001 kg (mᵉᶠᶠ = 0.001 kg), serves as a tangible illustration of the interplay between m′ and energy through E = m′c², culminating in an actual energy value of 9 × 10¹³ J.

The resulting energy value, 9 × 10¹³ J, solidifies the understanding of m′ in terms of energy-mass equivalence.

The conceptualization of m′ as an equivalent to an effective mass broadens our perspective on mass in relativistic scenarios. This shift allows us to view m′ not merely as a quantity but as an entity that dynamically responds to the relativistic effects of motion. It prompts a re-evaluation of our traditional understanding of mass, emphasizing its dynamic nature as an energetic entity.

In conclusion, this exploration has deepened our understanding of the energetic form of relativistic mass, shedding light on its equivalence to effective mass and its intricate relationship with energy in the context of special relativity. The implications of this conceptual framework extend beyond theoretical considerations, offering a nuanced perspective on mass in motion and its energetic manifestations.

Edwin Hubble: Pioneer of Extragalactic Astronomy and the Expanding Universe:

Edwin Hubble was an American astronomer who played a crucial role in establishing the field of extragalactic astronomy and is widely considered the leading observational cosmologist of the 20th century.

Hubble was born to John Powell Hubble, a businessman in the insurance industry, and Virginia Lee James, a homemaker who managed the household while John was frequently away on business. Raised in a family of eight children, Hubble won a scholarship to the University of Chicago in 1906. There, he served as a student laboratory assistant for physicist Robert Millikan, a future Nobel Prize winner, and graduated in 1910.

Awarded a Rhodes Scholarship from Illinois, Hubble spent three years at the University of Oxford, earning a B.A. in jurisprudence, a subject chosen at his father's insistence. After his father's death in 1913, Hubble had the opportunity to pursue a scientific career. Returning to the United States in 1913, he taught high school in Indiana for a year before entering the University of Chicago for graduate studies in astronomy. Hubble conducted his observational research at the Yerkes Observatory in Wisconsin, using a powerful 24-inch reflector telescope.

In a stroke of good fortune, Hubble completed his graduate studies just as the director of the Mount Wilson Observatory in California, George Ellery Hale, was seeking new staff. Hubble accepted a job offer to work with the observatory's 100-inch Hooker telescope, the most powerful in the world at the time. However, World War I interrupted his plans, and he enlisted in the U.S. Army. Hale held the position open for Hubble until the war's end, during which Hubble served in France, eventually rising to the rank of major.

Upon returning to Mount Wilson, Hubble shifted his focus from studying reflection nebulae within the Milky Way to investigating spiral nebulae, particularly the Andromeda Nebula. In 1923, he discovered Cepheid variable stars in Andromeda, allowing him to estimate its distance. This led to the realization that the Andromeda Nebula was a galaxy separate from the Milky Way. Hubble's subsequent research on redshifts and distances of galaxies provided crucial evidence for the expansion of the universe.

In 1929, Hubble published his first paper on the redshift-distance relationship, suggesting a linear correlation. Collaborating with Milton Humason, he presented convincing evidence in 1931 that supported the linear relationship and implied an expanding universe. This finding aligned with the emerging theory of an expanding universe based on general relativity.

Hubble continued his work at Mount Wilson, contributing significantly to the establishment of extragalactic astronomy in the 1920s and '30s. He published his influential book, "The Realm of the Nebulae," in 1936, outlining his approaches to extragalactic astronomy. Hubble's research laid the foundation for future astronomers, particularly at Mount Wilson and the Palomar Observatory.
 
During World War II, Hubble served in an administrative role at the Aberdeen Proving Grounds in Maryland. He died in 1953 due to a cerebral thrombosis and was survived by his wife, Grace, with whom he had no children. 


The Cyclic Model of the Universe: Infinite Cosmic Oscillations:

A cyclic model (or oscillating model) is any of several cosmological models in which the universe undergoes infinite or indefinite self-sustaining cycles. For instance, the oscillating universe theory briefly explored by Albert Einstein in 1930 proposed a universe experiencing an eternal series of oscillations. Each cycle starts with a Big Bang, expands for a duration, and concludes with a Big Crunch. During the interim, the universe expands for a period before gravitational attraction causes it to collapse, undergo a bounce, and repeat the cycle.

The Friedmann universe is a model universe developed in 1922 by the Russian meteorologist and mathematician Aleksandr Friedmann (1888–1925). He argued that Albert Einstein’s general theory of relativity demanded a theory of a dynamic universe, in contrast to the static universe that scientists had previously postulated. Friedmann proposed a model involving a big bang followed by expansion, subsequent contraction, and an eventual big crunch. This model assumes a closed universe. However, he also suggested alternative solutions, including an open universe (expanding infinitely) or a flat universe (continuing to expand infinitely but gradually approaching a rate of zero).
