While we may think of dust as a nuisance, there is a lot more to it than we give it credit for. We can find it everywhere…even in space, and it has a bigger impact on our lives, the weather, and our environment than we realize. YouTube channel PBS Digital Studios looks at this small, yet powerful ‘substance’ in today’s video.

Given: The Big Bang - Plasma cools to create a dust cloud
Given: Dust cloud still coalescing today Note: Galaxies still forming etc.
Estimate: how many different basic elements could be formed (know/unknown)
Given those figures: Estimate - How many different ways could those elements be combined to create: Suns/Stars which can be observed and used as a check on theory, and, Planets/Moons and Asteroids which could also be used as checks on theories.
Then: When Theory checks made to reach almost certainty of as near to 100% as feasible/possible.
Given: Variables reduced to near certainty about various elements created by Big Bang to create Stars/Planets etc.
Estimate: How many ways could those elements combine to create Life/intelligence?
E-gads! Most of that Space Dust falling on your head is probably alive!
