When exploring the possibility of parallel universes, we conclude that Physicist Hugh Everett's many worlds theory isn't scientifically adequate. To illustrate, we note the observational challenges of the many worlds interpretation, where "definite measurements arise from a deterministic wave function evolution that superimposes the state...

Every aqueous (water-based) solution will have a pH that is acidic, basic, or perhaps neutral. pH is a measurement that is used to quantify aqueous solutions into a range of values known as the pH scale. If the solution is basic it will be higher...
Chemical elements that produce colors in fireworks
By: B.W. Harold
The science of pyrotechnics is a fascinating and wild ride. When the shell of a firework is created, it is a careful balance of chemistry and art. Like all arts it requires relentless study and artful design. So what makes these beautiful balls of fury...

Alternative views on String Theory
By: Ray Burke
Noisy Strings: Scientists often use the analogy of quantum strings as being like instrument strings, under tension and vibrating through dimensions. But they never talk about the quantum strings themselves making a sound. This always seemed peculiar. If strings were isolated from the vacuum would...
Space Star Future Asimov
By: Colin Gallagher
If the human race stays on its current trajectory in the realm of space travel, then humans will never reach the stars. This is not because of a lack of technology, or innovation. Eventually man will discover the secret to interstellar travel, but by then...

Stargazers have a natural tendency to draw lines between random collections of dots. The patterns and pictures that they see are known as constellations. The ancient Chinese, the Babylonians, the Greeks and the Australian aborigines have all seen these shapes. Ptolemy named forty-eight of the...
Navigating the oceans by the stars in the sky
By: Metta Jane Hills
Stars above tell us we are higher beings. Why? For we are the only critters on Earth who observe them or at least notice their design in the sky. From there we have used them to help us navigate. We are not mere ants as...
How to use magnetism to test gemstones and minerals
By: Allan Taylor
The most common magnetic mineral is appropriately named "magnetite" an iron oxide of chemical composition Fe3 O 4. In olden days it was called lodestone because pointy fragments when suspended on a string would line up pointing north and south according to the earth’s...
