The Scale of The Universe

Consider the dot at the end of this sentence. Imagine it is on a printed page instead of your computer. If it were, it would contain around 100 billion atoms of carbon. If you wanted to see those jiggling atoms with your own eye, you would have to enlarge that do to the size of 100 meters. About as big as a football (Euro or American) field. You would then …

Shouldn’t we want our leaders to be smarter than we are? Neil deGrasse Tyson (Part 3)

Here is the third part of my chat with renowned astrophysicist Neil deGrasse Tyson. In this clip, you’ll see us discuss a couple of subjects. First, Tyson responds to my questions about scientific literacy (or, should I say, the lack of same). His answer to my questions were more wide-ranging than even I expected; I think it was Tyson at his best as a critical thinker as to how science …

Conversation with Neil deGrasse Tyson-Was Pluto Worth It?

Neil deGrasse Tyson gets LOTS of questions on Pluto. When I sat down with Tyson on Friday, I considered asking nothing about it. Instead I asked just one: You used the demotion of Pluto as a way of teaching science and scientific method to millions of people. Was it worth it???

Did The Media Miss The Boat on the Youngest Black Hole?

You likely heard about it a few days ago. NASA announced the detection of a supernova turning into a black hole. It was big news and justifiably so. The story starts back in 1979 when an amateur astronomer observed a supernova. It was the third one seen in 1979 and thus named 1979C. Yes all that astronomical numbering is real complicated you know;). You probably know that a supernova marks …

Would you survive an asteroid hit? Find out here.

I’ve often wondered about something. Suppose a 1000 meter wide space rock  were to hit Nashville, TN. Would I survive here in Huntsville in North Alabama? It would depend on many factors of course. Nashville is about 165 km to my north. That’s a BIG factor.   The size of the asteroid, and the angle of impact, are others. Let’s say that it hit at a 60 degree angle and …
