Physical cosmology, as an alternative to astronomy, is an area of science devoted to general understanding of large-scale structure and dynamics of the entire universe and is essentially concerned with questions regarding its nature and origins.
It studies such fundamental questions as the nature of space, the nature of time, the composition of matter on other planets and the origins of our solar system. It is also interested in such issues as the validity of Einstein’s theory of relativity and the accuracy of modern measurements of cosmological parameters like black holes, supernovae, gamma-ray bursts and extrasolar planets. It also studies the behavior of space weather – clouds, rain, snow, hail, and wind.
Space-time is the only thing that is absolutely constant in the universe, and it is measured by an Einstein field.
Einstein’s special theory of relativity established that space-time itself is nothing but a wormhole, similar to a tunnel through which light can pass. Contrary to popular belief, however, Einstein realized that space-time can be curved, and that it contains many different levels, just as a wormhole does, and these “levels” are not necessarily of a uniform size and shape. These Wormholes, or “branes” as they are more commonly known in the scientific community, can be very long and even irregular in their shape, with some leading to what is known as “brane decay” where the total volume of the brane dissipates over time.
Another important aspect of physical cosmology is the relationship between space, time and gravity.
Space-time is nothing but a road at the edge of the continuum, a region where time is distorted and stretched beyond its natural boundaries. Gravity within this space is a complex phenomenon in itself, with accelerating “stars” on white dwarf stars being an example of this, as well as satellites orbiting around our sun. Albert Einstein sought to give a unified overall theory of gravity, one that would describe all phenomena, including the creation of the cosmos and the survival of life on earth.
A major challenge for Einstein was to create a unified field theory which would provide a unified explanation of all physical laws and predictions.
For his ideas to work he had to effectively merge space, time and general relativity together. His general theory of relativity, or relativity on space and time, beautifully captures many concepts of physical cosmology and theory of relativity, including black holes, Planck’s constant and the concept of general relativity.
Though Einstein did not actually solve the Grand Unified Theory, he greatly helped to popularize it. The resulting model of a unified field was the subject of what came to be known as Planck’s Constant. To this day it is still an enigma how energy appears to be spread throughout the entire universe.
Einstein’s equations are an essential part of physical cosmology and play a key role in our understanding of both the past and present universe.
Because general relativity is designed to give an account of space and time, Einstein wanted to incorporate time into his theory. His theory of relativity provides an accurate description of how the evolution of the entire universe occurred. In this way it explains why in the past the universe was structured in a particular way. It also explains why in the present, the universe is in a state of accelerating expansion.
Quantum mechanics and Einstein’s special theory of relativity establish that the laws of Newtonian physics are the same in all universes.
However, while general relativity shows how the universe is structured, quantum mechanics is responsible for explaining how energy and matter come into existence and how they travel through the entire universe. Albert Einstein received a Nobel prize for his achievements in both fields. Many other scientists and cosmologists throughout the history of science have given credit to Einstein for laying the foundation for modern physics. Nobel prize winning scientists including Planck, Kipman, and Weinberg considered him to be one of the greatest physicists of all time.
Albert Einstein was born a poor family man in Munich, Germany.
He attended college and worked as a clerk for a jewelry store before turning to physics. After completing his studies he became deeply interested in physics and started to study mechanics, mathematics, and astronomy in his free time. After becoming a professor at the University of Munich he began his great research on relativity and became one of the greatest theoretical physicists of all time. During the 1800’s, Einstein worked on developing a theory of relativity called the theory of relativity. According to this theory, space and time are distinct and separate entities, thus affecting the behavior of ordinary physical systems.
The development of quantum mechanics led Einstein to conclude that space and time are independent entities independent of each other.
He further deduced that the universe contains energy equal to the whole force of gravity, thus the total amount of energy in the universe is subject to constant change. Einstein’s theories concerning the relations of general relativity with quantum mechanics came very close to predicting the birth of a new life form called planets’ around other relatively stationary massive bodies.
Apart from this he also formulated the theory of relativity that has become one of the most important theories in the history of science, even though many doubted it at first. A number of phenomena that were attributed to the physical laws of the universe were proved to be real events by the observational techniques conducted by Albert Einstein during his long life.
