Summary

Mordehai "Moti" Milgrom is an Israeli physicist and the Isidor Rabi Professor Emeritus of Physics in the department of Particle Physics and Astrophysics at the Weizmann Institute in Rehovot, Israel. He received his B.Sc. degree from the Hebrew University of Jerusalem in 1966. Later he studied at the Weizmann Institute of Science and completed his doctorate in 1972. In 1981, he proposed Modified Newtonian dynamics (MOND) as an alternative to the dark matter and galaxy rotation curve problems. Milgrom suggests that Newton's Second Law be modified for very small accelerations. In the academic years 1980–1981 and 1985–1986 he was at the Institute for Advanced Study in Princeton. Before 1980 he worked primarily on high-energy astrophysics and became well-known for his kinematical model of the star system SS 43.

0:00.0	Welcome everybody to another exciting episode of the Into the
0:09.6	Impossible Podcast featuring a legend, a famous legend, maybe some say an infamous legend in the field of cosmology and in particular, no pun intended, dark matter, research and objections to dark matter, and that's Dr. Mordecai Mughty Milgram of the
0:27.8	Hyam Whitesman Institute in Rehovot Israel
0:31.4	He joined us in late in the afternoon, early evening in Israel while I was here in California.
0:36.6	And he's really, as I say, a legend in cosmology because he has perhaps the most seriously taken of all objections to dark matter is his modified
0:45.1	Newtonian dynamics theory. The modified Newtonian dynamics does just that. It
0:50.1	adjusts certain parameters as Mutty will describe in this video in order to match the
0:55.2	observations that astronomers have known about since the time of Vera Rubin who, fun fact, was trained here
0:59.7	at UC San Diego by none of them my late great colleague Margaret Burbage and how to do
1:05.1	spectroscopy and Margaret was doing rotation curves too but she never really
1:08.6	thought much of it and really didn't pursue it the same way Vera Rubin did and
1:11.7	you'll hear about other applications of Monde and challenges to Monde from
1:16.6	audience questions such as those from friends on Twitter or on my YouTube
1:21.6	community tab so reminder you can always find out what I'm up to by going to one of those two locations, Dr Brian Keating on YouTube and on Twitter, and occasionally on Instagram but mostly not. And I also send up my newsletter, Brian Keating.
1:33.9	Com slash list.
1:34.8	You can join that.
1:35.8	You may be entered to win a little bit of space schmutz,
1:39.0	some dark matter from our cosmos, namely dust from a meteorite. See the website for more details. U.S. entries only, I'm afraid,
1:47.3	it's too difficult to ship overseas and too expensive. But at any rate, we talked about many different things, including the famous bullet
1:54.4	cluster, superfluid dark matter, popularized by none other than past guest and upcoming
1:59.6	guests of being a Haasenfeldr. Look for her episode on her newest book, Existential Physics coming soon.
2:05.2	And we talked about his work with the relativistic version of Mond, which is called Tebez and other things
