New Support for the Theory That Life Originated in the Cosmos

The scientific method was not developed on a whim. It was not designed as a method to decrease unemployment rates or keep children in school longer. The scientific method was created to unearth the great mysteries that have plagued mankind since the dawn of time. What is life? What is reality? Why are we here? The scientific method aims to provide a framework to understand our universe so that we can answer these questions and rid the universe of questions. One of the fundamental questions in our understanding of the universe is, where did life on Earth come from? Today, we have a new theory about how life may have been brought to Earth that seems unusually probabilistic.

Researchers at the University of Edinburgh have hypothesized that interplanetary dust may have been the vehicle of choice for the original biological organisms on our beautiful blue planet. Earth is constantly being bombarded with space dust that, for the most part, bounces off our atmosphere and passes right by us. This dust is hitting our atmosphere though and these researchers are hypothesizing that biological organisms may have been able to attach themselves to particles in our atmosphere when they collided with Earth. This would be a tremendous discovery; it would prove the existence of life in the cosmos. Better yet, this would suggest that life is close in our universe, perhaps even in the Milky Way galaxy, if it can make it to Earth on these particles. While it may be difficult to imagine biological organisms surviving long in space without food or water, it’s important to remember that these would be extremely small organisms and, even on our own planet, the smallest organisms are living in environments we can’t even fathom. Perhaps a few resilient organisms took the space dust express straight to Earth and started the majesty that we now call life.
