On a murky day a long time ago, a creature stood up and gazed at the sky to wonder at the vastness of the space. Often wandering in search of food and shelter, its mind veers off this activity to look up at the heavens. Not much has changed today even with the web of activities that man does and aerospace companies in Maryland provides an opportunity for enthusiasts to explore space.
The vastness of time and space cannot be measured. Various theories have been proposed as to its beginnings. The most prominent is the big bang theory. A big cosmic explosion happened trillions of years ago the flung particles into deep space. The speed with which the particles were flung was so forceful that collisions fused them together.
Forces in space cannot be fully described in words nor in mathematical formulas. All man can come up with are theories and postulations. No one can explain why galaxies do not merge and why it can stand alone in the vastness of space. The galactic system is just a microcosm of what is happening universally. At glance it appears to be static but it actually is expanding.
Solar systems normally have a star at the center on which planets revolve. The system that is home to earth has nine planets and earth is the third nearest the sun. The inertial pull of the sun keeps the planets in fixed orbits around it and all have different speeds in which to complete a cycle.
A small product to the explosion is the planet earth. It is the only known planet that harbors life, which is as far as human beings are concerned. It consists of multiple layers from the core up to the surface. The core is of dense solid material. The middle portion is of molten rock known as magma. The outermost crust holds the water bodies and the landmasses.
Deep space has always been the realm of science fiction. Many a TV program have been produced depicting man travel into space. One movie is very popular all over the world. It features futuristic spaceships as well as other objects like the light saber. Travel is not conventional in this movie, jumping in hyperspace takes only milliseconds. Such is the imagination of man.
This contraption has evolved tremendously over the years. Races were organized that stimulated rapid development. Early models were made of fabric and wood. Today almost all are constructed of metal in its various states. Developments in engine technology also hastened the modernization of aircraft. Originally these were propeller driven and powered by engines mounted in the framework.
During world war two one nation created the jet engine. This revolutionized the aircraft industry. It was light weight and was more powerful than conventional engines. It was capable of making thrusts that could reach the speed of sound. Most commercial and military airplanes at present use this engine in its various forms. Two examples are the ramjet and the turbojet.
Fully developed nation are the richest on the planet and are the only ones that can afford to fund a space program. The most powerful nation on earth embarked on this endeavor and have successfully transported man to the moon. This costs billions of dollars in terms of planning, organizing, coordinating, and managing the program. This was principally funded by government.
