Scientists are expert observers. Because of this, they can help us develop a keener view of the world — the cosmos.
- There are many people who have discomfort engaging with a scientific perspective of the world — for some, for instance, it conflicts with what they were taught during their religious upbringings.
- We can all gain a greater view of life — the cosmos — by getting to know scientists, especially when we're at an impasse in our lives.
- Scientists' view of the world retains a "distance" to it — it's observational, fact-driven. This helps with finding consistent principles in nature.

There's something all of us—physicists included—are getting wrong about dark matter, says Neil deGrasse Tyson.
There's something fundamental we all need to understand about dark matter—it may not actually be matter at all. Neil deGrasse Tyson has a bone to pick with this misnomer that is distracting physicists and the public from the real discoveries to be made. Scientists know very little about "dark matter", and in fact it can only be observed indirectly by its effect on other objects. Tyson has a few suggestions for its re-naming: how about "Fred", he jokes, which is a name devoid of any implied meaning—suitable for our current level of knowledge. But if you want it to sound sexy and be accurate, then the way to go is dark gravity, according to Tyson. Why? Because when you add up everything in the universe—the stars, moons, gas clouds, black holes, everything—85% of gravity is unaccounted for. That is so-called "dark matter". What makes it so interesting isn't the wild-goose-chase question of whether or not it exists, but why it doesn't interact with ordinary, known matter? On the way to explaining that dark matter "doesn't give a rats ass about us," Tyson explores ghost particles, the essence of objects, and why we haven't found any dark matter planets. Tyson's new book is Astrophysics for People in a Hurry.
