declare, if thou hast understanding.
Where wast thou when I laid the foundations of the earth?
declare, if thou hast understanding.
Who hath laid the measures thereof, if thou knowest?
or who hath stretched the line upon it?
Job 38:3-5
"What is dark matter?
We don't really know what this stuff is, but scientists estimate that
dark matter may make up about 25 percent of the total universe.
It's a substance that works something like a spider's web, holding the planets, stars, and entire galaxies together.
There's plenty of evidence that it exists, but it's a mystery what exactly it is. Maybe it's a compound of an undiscovered particle? Maybe it's a previously unknown property of gravity? No one's sure." BL
