Imagine an atmospheric explosion so powerful that 800 square miles of trees fall to the ground, pointing outward from a central point. That very thing happened on June 30, 1908, in a very remote area of Siberia called Tunguska. The event is named for the...
Relativity Stellar Aberration Ether Theory Michelson Interferometer Einstein
By: Joe Murray
The theory of relative time arose through the six classic pillars of science: a field observation, supporting verifiable measurement, explained by a relevant theory (paradigm), a follow-up experiment, which, failing to support the relevant theory, led to its overthrow and replacement by another theory. See...
Questions Raised about the Moon Hoax
By: Lynn Jackman
Looking through those who argue that we never went to the Moon, I find that much of it is conjecture and gives analogies. Where is the refutation of the actual evidence? They repeat claims and analogies, but never delve into the hard questions. Let's offer...

Alternating current (AC) and direct current (DC): A simple explanation
By: Francis Jock
Direct current and Alternating current are common terms used to describe the two forms of electricity we use every day in countless different situations. These terms are applied to many different types of devices we have come to take for granted in our age of...

Why ice floats on water
By: Heather Lyon
Ice floating is one of the unique properties of water. Most other matter is denser when it is frozen or in a solid form and therefore would sink when place in the liquid form of the same matter. Ice floating is actually a very important...
An overview of the chemical element Hydrogen
By: Janet Grischy
The stars are mostly made of hydrogen. Not entirely though. The sun, for example, is only 91.2 percent hydrogen atoms. It converts hydrogen to helium atoms, in a fusion reaction that gives off the energy that powers all life on earth. Taken together, hydrogen...
The planet Mercury
By: Roberto Alvarez-Galloso
When writing about the planet Mercury, there are many factors that come into mind. Before the existence of advanced studies about Mercury, it was once thought [taken from the book titled "The Universe" by David Bergamini and published in 1969] that Mercury faced one side...
