Gliese 581C is believed to be approximately four times the size of Earth and calculations show that its orbit is within the habitable zone around the star Gliese, a red dwarf star seen from Earth in the constellation Libra. 581C is much closer to...

The other day, the front page of CNN.com regaled for all of five hours in the announcement that an international team of scientists had found a planet that could potentially support life. The Time-Warner company can be forgiven for its short attention span: these...

20 Light years sounds like a long way. However in galactic terms Gliese 581c is our next door neighbor. A relatively small amount of human effort has been put into searching for planets like our own or conceiving how we may actually get there...

Absolutely, anything is possible! Life on other planets is very feasible. With there being an estimated 20 billion stars in the universe, couldn't there be at least one other planet with life orbiting just one of those stars? What if only 1 out of 100...

What are black holes? And how are they formed?Black holes are probably the most fascinating (theoretical) objects in astronomy. Such objects, which scientists believe must exist, would account for the spin-rate of our galaxy, which cannot be explained by the combined mass of the...

Slower than the speed of light?Big bang cosmology based on a varying light speed constant.Light speed in today's vacuum of space-time fabric is observed to be 299,792.458 km/second.(*1) This is the peak velocity of light through the lightest, most basic...

In physics, a wormhole is a hypothetical topological feature of spacetime that is essentially a 'shortcut' through space and time. A wormhole has at least two mouths which are connected to a single throat. If the wormhole is traversable, matter can 'travel' from one mouth...

With the recent discovery of a possibly Earth-like planet some 20+ light years from Earth this is a subject that will be given thought by many people (especially those who would like to build a civilization from scratch). Given many more thousands of years of...

Time travel is possible if the facts as stated by the scientific community are true and accurate. But as with many people I see many problems to solve in order to get to the Time Travel Port. And to answer a point I see over...
