Space and time theory: Wormholes
By: Gemma L. Reece
A wormhole is described as any structure connecting two regions of space-time which are otherwise very far apart or unrelated, somewhat like a tunnel with two ends where each end is in a separate point of space. Some scientists have theorised that a wormhole is...

Science fiction writers often look for a device which can transport objects through space and time. A wormhole is a theoretical device which might allow such a transport. According to theoretical physics there might be a shortcut through spacetime which could be exploited. When the...

The International Linear Collider, also known as the ILC, is a linear particle accelerator slated to be built in the late 2010s. It will publish its Technical Design Report in 2012. The host country for the ILC has not yet been chosen, and it is...
The four fundamental forces of nature
By: Trenna Sue Hiler
Physicists recognize four forces of nature. These are identified as interactions that include all known phenomena in nature. Some of the four are easy to recognize because they are seen every day. Others are happening all around, but not necessarily seen.GravityWhile gravity is the...
What is a positron?
By: Rex Trulove
The word, positron, sounds like it might have come from Star Trek or some other science fiction series or movie. However, positrons are real particles. To understand what they are, it is helpful to understand some of the properties of the particles of an atom...

To understand AC or DC power, we need to understand the nature of electricity itself. Electricity is the movement of free electrons between areas of different potential through a conductive medium. Electrons have a negative charge. Free electrons are those that can be forced to...

In 1995 Leonard Susskind a Professor of Theoretical Physics at Stanford University published an unusual paper. He suggested that the entire universe might be a hologram in which people are just seeing a projection of the real thing. His theory is supported by a Dutch...
The difference between AC and DC power
By: Ocean Littlefield
Fundamentally, it is a difference between how the electrical energy moves through the wires of a circuit. Simply said, DC, or Direct Current, moves in one direction through the wires, from point A to point B. On the other hand, AC, or Alternating Current, moves...
What is the next leap in physics?
By: Caleb Haines
Physics is an ever changing world of understanding. One day you may think that the Earth is made up of simple things like stones and water and the next thing you know, objects are really made up of miniscule particles or even infinitely small strings...

Charcoal is made up of carbon and ashes produced through drying and removal of volatile residues from animal and vegetation substances. It has been used for many different purposes for centuries and alterations to its constituency and the structure could provide charcoal with properties that...
