The late Dr. Carl Sagan loved to tell us our bodies are made of star dust. James D. Watson told us that life was just a matter of chemistry, a sequence of naturally occurring chemical reactions building more and more complex molecules. But what is...
The real size of our solar system
By: D. Vogt
Essentially, the real size of the solar system depends on which theories you choose to accept, although the most distant known object, the dwarf planet Sedna, may travel as far as 90 billion miles from the Sun before looping back inwards on a highly elliptical...
Would aliens look like us?
By: Lee Pringle
Why Movie Producers Are (mostly) Right About Extraterrestrials. There have been a lot of movies recently about aliens coming to Earth for whatever reason, usually involving attacking us. While the plots in these films may be different, they all have one thing in common, the...
What are the most abundant elements on Earth?
By: James Johnson
Elements, they are the basic building blocks of all matter and found everywhere. They are what form the Earth, and everything upon it. Even if you believe in God, he still made the elements to make us! They are what comprise the rocks that form...
Difference between terrestrial and Jovian planets
By: D. Vogt
Since the 1990s, the increasingly rapid discovery of extrasolar planets (planets orbiting other stars) has turned the traditional division of planets into rocky or terrestrial planets (like Earth and Mars) and Jovian planets or gas giants (like Jupiter and Saturn) from a handy shorthand for...
How mathematicians discovered planet Neptune
By: D. Vogt
Almost all of the planets in our Solar System have been discovered visually, by astronomers - including Pluto (no longer officially a planet), although in that case it took the added assistance of some photographic plates. The exception is Neptune, which at over 2.8...
Explaining why ice floats
By: James Johnson
Why does Ice float? Because God made it that way so it wouldn't crowd out the little fishes by sinking and filling up the seas, then getting them all frozen. This was an explanation by a four year old child. Sounds like an interesting theory...

Most stars, around 90% of the total, are red dwarfs. We don't see them in our night skies, because they are too faint, but they make up the vast majority of the Milky Way Galaxy. They burn slowly and coolly (with surface temperatures of around...
Chemical names of substances found around the home
By: James Johnson
Everything physical is comprised of elements. To the ancients, those elements were simple: fire, earth, air, water and Aether. Fortunately this didn't mean much and so common names came into being. Now the elements are more clearly designated and so we have chemical names as...

Physicists have been working on finding a way to time travel for years. As far as we know without success. But will we ever break the time barrier or will it always be something we strive to do? The English mathematician, Stephen Hawking once proposed...
