Some writers may approach this question from a philosophical perspective, others entwine it in notions of religious belief. But when the question is asked in the strict context of what is scientifically possible, neither philosophical postulates nor religious beliefs can meet the scrutiny required by...
Astro physics - Stellar Distances: Light years, parsecs and AU's explained
By: Lawrence George
Space, as the wonderful Hitchhikers Guide to the Galaxy once said, "...is big. Really big." And this causes us problems when we want to describe distances. The vastness of space quickly confounds the units we use in everyday life. Talk of billions of...
Is there a viable alternative to tectonics?
By: James Bowles - 448482
Is there a viable alternative to tectonics? Yes! I.) INTRODUCTION Three themes of discussion run jointly through this article: a.) The fallacy of the tenets of the current earth sciences (i.e., plate tectonics); b.) Nature’s laws (physics) as the basis...

GAMMA RAYS ALL THE WAY! Gamma rays are the most important light source of energy in modernsociety. Well, what on earth are they? Gamma rays are a type of electromagnetic wave with the smallest wavelengths and have the most energy from any other waves in...
What is the technological singularity?
By: Daniel Relph
A technological singularity is a technical innovation that just sucks everything in. We have the Stone Age, when all the tools were made with stone. Then there is the Bronze Age when there was a big push to make things of bronze. Then there was...
The use of composite materials in aviation
By: Jordan Cropper
In the early days of aviation, the pioneers of flight struggled with one major problem - weight. Early engines had difficulty producing enough thrust to overcome the relatively heavy airframes. However, improved materials technology has lead in the last few decades to the creation of...
The use of composite materials in aviation
By: Srikanth Radhakrishna
Aircraft manufacturing technology has come a long way from the days when engineers used wood and steel to construct aircraft. In the early 1920s aluminium replaced wood and steel, which also improved aircraft design. With advancement in technology in the aviation industry, composite materials are...
The history of the atomic bomb
By: D. Vogt
The history of the atomic bomb has essentially occurred in the three stages: the early theoretical research into atomic weapons, leading to the development of the first "A-bombs" in 1945 and their subsequent imitation by the Soviet Union; the development of the hydrogen bomb or...

Throughout Nature, there are "cycles". Some cycles are short enough to be observed personally. (Like that bouncy puppy who grows up, ages, and dies before you head to college). Some cycles are longer than a lifetime, and have to be referenced in historical records. (Like...

Stephen Hawking, the world renown theoretical physicist made his mark with fuzzy black holes and naked singularities. No those aren't drinks created by a Las Vegas bartender, but cosmological objects that may be the astronomical gears running our entire universe.Hawking, 68, is no stranger...
