He came to the conclusion that the physical world was constantly in a state of motion and change. He believes that everything is in movement between what it potentially will be and what it was. For example a cup of hot chocolate is potentially cold and will eventually become so. He was also the inventor of meteorology. While studying the planets he realized that they move eternally.
Phase changes began as this shape began to expand and cool, resulting in the formation of different types of energy: gravity, electromagnetism, and the ‘strong’ and ‘weak’ nuclear forces. This ball of mass continued to expand and matter and energy became more stable, resulting in elements such as helium, hydrogen, and lithium. These phase changes continued until new complexities were reached, pushing the universe towards the next thresholds. Thus the Big Bang theory is widely accepted as it examines the various stages of creation. There is much evidence behind the Big Bang theory, but it continues to face various challenges.
This is because there is a relation between the energy of light and its frequency: the greater the energy the higher the frequency. As light travel upwards in the earth´s gravitational fields, it loses energy, and so its frequency goes down. To someone high up, it would appear that everything down below was taking longer to happen. A prediction tested, showed that the clock at the bottom, which was nearer the earth, was found to run slower, in exact agreement with general relativity. The difference in the speed of clocks at different heights is now of considerable practical importance’s, with the advent of very accurate navigation systems bases on signals from satellites (GPS).
The strength, distance, and length of the wind gusts determine how big the ripples become. The crest of a wave is its highest point. Wavelength is the horizontal distance, and wave height is the wave’s vertical distance. The last type of motion is currents. Currents are the ocean’s constant flow of water that is pushed on by either the wind or from tides that are caused by the moon’s gravitational field.
Longitudinal wave The vibrations of the object set particles in the surrounding medium in vibrational motion, thus transporting energy through the medium. For a sound wave traveling through air, the vibrations of the particles are best described as longitudinal. Longitudinal waves are waves in which the motion of the individual particles of the medium is in a direction that is parallel to the direction of energy transport. Sound waves in air (and any fluid medium) are longitudinal waves because particles of the medium through which the sound is transported vibrate parallel to the direction that the sound wave moves. As the vibrating string moves in the forward direction, it begins to push upon surrounding air molecules, moving them to the right towards their nearest neighbor.
At the very start, the entire universe was about a size of an atom. It was termed by Georges Lemaitre as the “primordial atom”. As one of the pioneers of in the make of the big bang theory, Georges Lemaitre proposed this new theory. At that time, this theory has explained many difficulties that were met by the theories proposed previously. For example, a theory states that the universe is infinitely large with an infinitely amount of stars was met by the Olber’s paradox.
Also, for every force, there is an equal and opposite force acting against it. With the exception of gravity, the electromagnetic force is the force responsible for practically all the encounters in daily life above the nuclear scale. Roughly speaking, all the forces involved in interactions between atoms can be explained by the electromagnetic force acting on the electrically charged atomic nuclei and electrons inside and around the atoms, together with how these particles carry momentum by their movement. This includes the forces we experience in pushing or pulling ordinary material objects, which come from the intermolecular forces between the individual molecules in our bodies and those in the objects. With the exception of gravity, electromagnetic phenomena as described by quantum electrodynamics account for almost all physical phenomena observable to the human senses, including light and other electromagnetic radiation, all of chemistry, most of mechanics (excepting gravitation), and, of course, magnetism and electricity.
The theory of Black Holes and its process is one of the most unique studies of the universe, in that with each discovery made, we un-lock closed doors to knowledge of how the universe was made. In 1798 a French Mathematician Pierre Simon de Laplace came up with the first theory of a Black Hole. He agreed with Newton, that when enough mass is added to a star like the sun, the gravitational pull would become so great that the escape velocity would equal the speed of light. Therefore, the star would blink out and become an invisible star. More than a century later, Einstein, came up with the theory of relativity.
Earthquake shaking and damage is the result of three basic types of elastic waves. Two of the three propagate within a body of rock. The faster of these body waves is called the primary or P wave. Its motion is the same as that of a sound wave in that, as it spreads out, it alternately pushes (compresses) and pulls (dilates) the rock. These P waves are able to travel through both solid rock, such as granite mountains, and liquid material, such as volcanic magma or the water of the oceans.
This principle was first used in a rocket engine by Robert Goddard. Very nearly all modern rocket engines that employ hot gas combustion use de Laval nozzles. Its operation relies on the different properties of gases flowing at subsonic and supersonic speeds [1, 2]. The speed of a subsonic flow of gas will increase if the pipe carrying it narrows because the mass flow rate is constant. The gas flow through a de Laval nozzle is isentropic (gas entropy is nearly constant).
