5% only

1st off, Happy October 1st!

After reading about dark energy and dark matter in the universe from Nasa.
I am slightly disturbed, moderately relieved but mainly intrigued.
The gist according to me...
Even if you learned everything there is to possible learn in the whole wide world, it would only account for about 5% of everything in the universe there is to know. So the next time something seems impossible just think that there's a 95% chance that you're wrong. There's a whole 95% that's unexplained and unseen.

If there is so much that we haven't seen and don't know how can we be 100% of what we do know?

When I only know one side of a story I feel that I don't know much at all. If science knows that they're not seeing the whole picture how can they be sure they're describing what they do see accurately?

If you see one bead are you sure you know what the whole necklace looks like?

Are we doing that on a regular basis?

Buying a necklace based on one bead?

Accepting a theory based on one known truth?

Am I stretching this a little far with that analogy?

hehe all the best and cheer's to a great weekend.
