Good morning, Rallypoint. Today's Astronomy Picture of the Day (APOD) is titled "Dark Matter in a Simulated Universe." Just what is 'dark matter'? Simply put, it is a physical thing that we can't see. Physicists use the term 'baryonic matter' to describe most that may be encountered or experienced in everyday life that has the property of mass. Non-baryonic matter, as implied by the name, does not have the property of mass. This includes free electrons and dark matter.
The featured image from the American Museum of Natural History's Hayden Planetarium previous Space Show Dark Universe highlights one example of how pervasive dark matter might haunt our universe (well, it is getting close to Halloween). Here, complex filaments of dark matter (black) are strewn about the universe like spider webs, while the relatively rare clumps of things we recognize - galaxies, stars, and planets (e.g. us) are shown in orange. The term 'baryogenesis' is used to describe the physical process that unfolded to create this asymmetry. Which may be as close (for now) as we get to understanding what actually happened in Genesis 1:2-3.

Far more dark matter than what we can see...fascinating as always Maj William W. 'Bill' Price

Every time I read that we will never travel faster than light, I reflect on the fact that we have absolutely no idea what 83% of the mass of the universe is made of and, beyond that, an unknown energy force makes up 70% of everything. We are opining from our knowledge of 5% of what is.
Steve's off the wall prediction- We will be traveling faster than light within 200 years, if we do not off ourselves first. Probably a lot faster.

1SG Steven Imerman - By then you will just talk your text automatically, there won't be a way to do it manually!

Since our body could not withstand unfathomable g-forces we would have to be, somehow, molecular transported. Like "Beam me up Scotty"

True, bit it takes a little less than a year to get to light speed at an acceleration of 1g. At 1.2g you could be better than 4 times c in three years. Three years accelerating, 3 years slowing down at the same g force, and you're out about 10 light years. Not great, but quite doable.
