Since then, much of the material has been swept out of the Solar System or sent plunging into the inner planets in an event known as the Late Heavy Bombardment. The Moon's heavily cratered surface is the result of this violent episode in the Solar System's history. Epsilon Eridani's star system might undergo a similar episode of dramatic upheaval in the future, the astronomers believe.
Early Solar System
After some 5-10 billion years of stars forming and dying, a cloud of star dust formed and began to collapse. This so-called "solar nebula" was the womb of our solar system. The cosmic dust contained all the elements from which the sun and the planets are made and probably was a mixture of the exhaust from many supernova explosions. Here are some more examples of star forming areas in the universe: baby stars .
The cloud of gas and dust collapsed to disk and then into the sun and the planets. The early solar system was a a terribly violent place, as revealed by the scarred surface of the moon. Although collisions in the solar system still occur (meteorites, for example), there were a lot more collisions in the early solar system. One such collision is thought to have created the moon as shown here:
24 Hours of Chaos: The Day The Moon Was Made
For 25 years, scientists have pondered a theory that the Moon was created when an object the size of Mars crashed into Earth less than 100 million years after the Sun was born, some 4.6 billion years ago. The general idea has been run through the paces and massaged into shape and is now the favored explanation.

Without funding, you have no ship, no resources, no nothing.
I'm not being pessimistic, just practical and realistic. Technology is not the only boundry that has us grounded on earth indefinately.

The feasibility, or 'possiblity', if you will, of a Star System that resembles our own is not only likely, it seems inevitable, given the vastness of our Galaxy.
Canup and her colleagues did some new calculations and determined that the collision was much bigger than previously thought. The scientists say they found that the collision was so big that some of Earth's surface vaporized.
