Lasers and how light and matter interact
By: Laureen Manera
Simply stated, a laser is a device that amplifies light. The word laser is an acronym for Light Amplification by Stimulated Emission of Radiation. Laser light is vastly different from ordinary light, such as from a light bulb or the sun. It is highly monochromatic...

What is dark matter exactly? For one, dark matter is not dark but opaque since all matter is dark when not energized by string energy. So is dark matter Nuclear or another source of energy?The energy from the Dark Matter can be used as...
Quantum Physics is Time Travel Theoretically Feasible
By: Wenbin Nah
"Two paradoxes are better than one; they may even suggest a solution" -Edward TellerNo discussion involving the feasibility of time traveling can be considered complete without a discussion involving the paradoxes involved. Let us consider the paradoxes commonly associated with time travel and examine whether...
