Greetings Fellow Cosmonauts!
Please join us this Wednesday (7/3) as we continue our 12-week screening + discussion of the lecture series "Dark Matter, Dark Energy: The Dark Side of the Universe." In this series we will examine the key concepts of an expanding universe from Albert Einstein to Edwin Hubble, led by an expert in the field. We'll be continuing our journey this Wednesday with two lectures on the history of dark matter, how it was first discovered, and some of the methods scientists use to detect it. A description of lectures #5 & #6 are below:
Lecture #5: Galaxies and Clusters (2007, 31 min)
"Applying the laws of dynamics to galaxies and galaxy clusters, we find that more matter is required to account for their motions than can be observed. Some of the missing mass is hot gas; however, this is still not enough, and we need to invoke some new kind of particle in galaxies and clusters: dark matter."
Lecture #6: Gravitational Lensing (2007, 31 min)
"Another way to detect invisible matter is to use light as a probe of the gravitational field. Passing through curved spacetime, the path of a light ray is deflected due to gravitational lensing. Lensing demonstrates the existence of gravitational fields where there is essentially no ordinary matter."
Don't worry if you don't know anything about this subject. No prior understanding of Dark Matter, Dark Energy, gravitational lensing, relativity, or mathematics is required to appreciate this series and to participate in the discussion period. This is a safe-space for science and for humans who want to talk about science freely.
Now for some administrative details....
The space will be open for beverages and general schmoozing as early as 7:45PM. The viewing will start promptly at 8:25PM.
As usual, BYOB. +1's welcome (& encouraged!). Oh, and this is a pet friendly space. My dog is kind of an asshole, so I keep her at home, but if your pet is chill, feel free to bring 'em along!
There is a suggested donation of $2 which helps pay for the venue at Industry Lab. You can donate through the following methods:
cash: donation cup at event
You can also donate through meetup.com, but they take a 17% cut!!
Looking forward to seeing everyone Wednesday!
