I just spent 3 hours binge watching 'How the Universe Works.' When scientists don't know everything is blamed on black holes or dark matter.

I'm writing a strongly-worded letter to Neil deGrasse Tyson.

Ensure the words are as small as they are strong. He's not the brightest light in the science system.

This has been my belief for a long time. They are making educated guesses based on limited knowledge. I think they are very intelligent people but not very wise; as in they lack the awareness to recognize they are working blind and therefore should stop talking as if their theory is fact.

"The rest of the universe appears to be made of a mysterious, invisible substance called dark matter (25 percent) and a force that repels gravity known as dark energy (70 percent)."
