Dark Matter and Dark Energy


This is a 15 minute talk by Patricia Burchat.


How on earth is this political? It frequently occurs to me when I learn about stuff like this, that the people who are arguing over whether or not evolution is real, are missing some even bigger questions than that. I wonder if they have any inkling about how puny the question of evolution is in the midst of these other issues.


MardyS recently posted a link to a book review on his facebook page.

How We Know by Freeman Dyson is a book review of The Information: A History, a Theory, a Flood by James Gleick.

In the review Dyson says, Thanks to the discoveries of astronomers in the twentieth century, we now know that the heat death is a myth.. It seems to me that some of his discussion about the myth does not seem to be cognizant of dark energy as discussed in the video clip.

Speaking of the heat death paradox, Dyson says,

The best popular account of the disappearance of the paradox is a chapter, “How Order Was Born of Chaos,” in the book Creation of the Universe, by Fang Lizhi and his wife Li Shuxian.

Creation of the Universe published in Singapore: World Scientific Publishing Co., 1989.

Freeman Dyson is a world renowned physicist. I find it unlikely that I would know more about this subject than he does. I must have some misunderstanding if it seems to me he has some things wrong or at least not explained well.
