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.
Particles are flowing out like endless rain, colliding and joining to form substances and objects. The speed of light cannot even be used to measure the breadth and width of the universe. No knows what its form is and how it began. Something cannot come out of nothing. So scientists are still baffled as to who made the first matter and from whence it came to cause the big bang.
Galactic expanse can be deemed as smaller than that of the universe for it but an occupant. These huge conglomerations of stars may differ in form depending on how forces in outer space work. The gravitation force exerted by this system is strong enough to pull in objects and to repel other forces from swallowing it.
A Star or a sun is the centerpiece of a solar system. The gravitational pull that it exerts makes planets go around it constant circular path. Earth is one planet that orbits around its sun which is ninety three million miles away. It is a burning cauldron of hot gasses that feed each other making it last for billions of years.
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.
Flying like a bird has always been an ambition of man. It came to fruition with the invention of airplanes. The early models had wings shape like that of bird. Many an adventurer has been killed in flimsy flying machines. A huge step in the history of flight was the development of a lightweight engine that could be mounted on a frame and have enough power to achieve flight.
A flimsy flying machine was the first manifestation flight desire. To be free from the ground like a bird is an event that everybody dreams about. The first contraptions had engines in its early stages and could not provide enough power to lift the contraption which composed of light materials like cloth and wood.
The jet engine was simultaneously developed by two nations. These did have no propeller attached to it, instead, it uses air that is sucked the engine and blown out at the other end. It was more powerful and more fuel efficient that it can make an airplane travel at more than five times the acceleration of sound. Military and commercial aircraft have engines of this type.
People say that the last frontier is space. Nations have space programs with the purpose of exploring space beyond earth. Rich and powerful nations have place men into orbit around the earth using rocketry to thrust the vehicles free from planetary gravity and atmosphere. Satellites are launched into space using rockets, so far it is the only way to hurl huge object into the sky.
