Dark Matter and Dark Energy Lecture

We had an astounding lecture last night at my astronomy club.  It was by a professor at a nearby university, and she was amazing.  Her topic is Dark Matter and Dark Energy and if I tried to tell you about it, it would take days, trust me!  In the most simple explanation, believe it or not, the largest percentage of the universe is made up, not of what we can see, but what we CAN'T see - Dark Matter and Dark Energy!  So I was just taking photographs once in a while at the lecture and trying to find interesting photographs.  This is the professor pointing to an image of a supernova, which is when a star explodes.  I love this photo because she is standing in between the projector and the screen, so there are stars on her face.

She was really dedicated to helping our group understand some complex information and was very patient in answering questions.  What a wonderful speaker.

Here is one of our members asking a question during the lecture.  What I thought was amusing is the expressions of the other members as they watched him ask his question!

And the good thing was, as you can see, that the mathematics involved were really easy to understand, right?  You all "get" this, right?  The math explained here would take me two days to explain, IF I understood what it meant.  BUT...  She explained what each of the symbols meant and then what the significance of the equation meant, and that was the most important thing.
