Dark matter is one of the great mysteries in modern physics and cosmology. While the Standard Model describes the fundamental constituents of matter and their interactions, visible matter appears to account for only a small fraction of the Universe.
Join Sowmaydeep Dwivedi for a review of the discoveries that led us to our current understanding and current thinking about dark matter.
The asymmetry of matter and antimatter is one of the greatest puzzles in physics. All particles have antimatter versions that are nearly identical, but with mirrored properties such as the opposite electric charge. When an antimatter and a matter particle meet, they annihilate in a flash of energy.
If antimatter and matter are mirrored copies of each other, they should have been produced in equal amounts in the Big Bang. But today there’s nearly no antimatter left in the universe. We only see it in some radioactive decays and a fraction of cosmic rays. So what happened to it?
Dr. Mike Snow, IU professor of physics will talk about this mystery.
Physicist Mike Snow will join us for another Science Cafe, this time on the subject of gravity. Come learn the latest about the nature of the force that keeps us grounded.
Several things to note:
1) We’re starting at 7pm
2) We’re on the 3rd Wednesday
3) We’re at Hopscotch on Morton & Dodds
4) Hopscotch doesn’t have much food, which is why we’re beginning at 7pm (They do have great coffee, tea, beer, and pastries all the time.)
