Voyager – The Hits Just Keep On Comin’

The twin Voyager 1 and 2 spacecraft are exploring where nothing from Earth has flown before. Continuing on their more-than-39-year journey since their 1977 launches, they each are much farther away from Earth and the sun than Pluto. In August 2012, Voyager 1 made the historic entry into interstellar space, the region between stars, filled with material ejected by the death of nearby stars millions of years ago.  Scientists hope to learn more about this region when Voyager 2, in […]

Is There Any Such Thing as “Pure Energy”

Energy plays a tremendous role, not only in our technology-rich daily lives, but in fundamental physics as well. The chemical energy stored in gasoline gets converted into kinetic energy that propels our vehicles, while the electrical energy from our power planets gets converted into light, heat and other forms of energy at our homes. But this energy always seems to exist as merely one property of an otherwise independently-existing system.  The simplest, most familiar form of energy of all is […]

Are invisibility cloaks possible?

Have you ever wished you could hide under an invisibility cloak like Harry Potter or conceal your car with a Klingon cloaking device like in “Star Trek”? This video explores the science behind light, sight and invisibility. Though we can’t make ourselves invisible yet, some promising research may light the way or, rather, bend the light away.

How Could Parallel Universes Possibly Be Real?

Some Say When Right Conditions Exist – They Can Be Real The idea that things exist in a particular, well-defined state at all times where their properties can be determined so long as you can measure them well enough was fundamental to how we conceived of the Universe.  When quantum physics came along, that idea went right out the window, never to return. The Universe, at a fundamental level, is indeterminate. One possible interpretation — that of infinite parallel Universes […]
