"Dark matter and dark energy. It encompasses 95% of the universe, and we have no idea what it is. We can't even see it. We just know it’s there."
"According to NASA, about 68% of the universe is dark energy and 27% is dark matter. The remaining 5% is everything else."

If you don't understand these, or find them beyond belief, my faith in humanity is lost.
so much basic science in here.

Simeon,
One of my favourite mind blowers is that 1 tablespoon of Neutron star would weigh around 6 Billion Tons. It's simply staggering trying to wrap your head around that fact.

Alfreda,
A tablespoon of Neutron star weighs between 1 billion to 6 billion tons depending on what informational source publishes the statistic. The spoon size is irrelevant. The fun is knowing it's wicked heavy.

#12 No, we don't know dark matter and dark energy exist. They're postulated because they have to exist to make certain theories to work.

Exactly, was just about to say the same thing. It probably does exist but we don't actually know that it does, we just think it does because that's the only way the equations actually work...

we know exist, must exist or we are really bad mathematicians and that is unbearable

#14 A much rarer version of this condition is "Jamais Vu." It's doing something you've done so many times before, like tying your shoes or brushing your teeth, but all of a sudden feel like it's the very first time you're doing it.

All of those are pretty comprehensible to me I must say.
What I cannot wrap my head around is how we as humanity have come so far and yet at the same time are so mindboggingly stupid.

Don't blame all of humanity. It's only a few selected countries.
