We will now proceed. Yes. Yes. All right. News of the day in astronomy. Check it out. Said they found a quasar like ours today and they found the record setting quasar. That is a redshift of eight today. We'll talk about what that means. And that's pretty bizarre because theories just say there should not be this is like a hundred million solar masses think something like that. Huge. Speaker 200:01:00And it was unexpected that that black holes this big would have existed that Earth. And this gives us all kinds of interesting data about early universe and exactly what reorganization means and why we're excited or what's redshift seven point five. Yeah 800 million of means is exactly the topic up to date. So I love this class because the only kids that I teach are those like new science. We can understand on a weekly basis. So let's enjoy that jolly OK. In 134 news what are we having for news. Well exciting things include but are not limited to. We have. I'll Speaker 400:01:50just find ours. Find us where we weren't so much. We have years. We had finished by discussing we were talking about dark matter last time and I talked about the possibilities of machos with upstart Accuride. Administrative news. One is all of this paper is yours and please get up. We'll find out which is next Wednesday morning. The lunar observation we promised is up with this week and possible right thinks we might be able to do it Monday Monday your memory is already reading. Speaker 500:02:38So that means the moon is west of the sun so it'll be Monday morning. Speaker 100:02:42Thank you. Thank you. Now back to all aspects great stuff the. Speaker 600:02:50And I think 10 of you have filled out the Trinity everybody should think so thanks to those 10 the other 20 finally you get questions about where we are are things we have done science or otherwise. Before I launch in OK. So yes sir we talked about him already. Speaker 100:03:16Saying one thing. Speaker 300:03:20By the way he said something perturbed diktat went floating around I'm told it's up in the sun's gravitational influence. We did talk about that. Speaker 500:03:31Literally you were not here. OK. Onwards. So so I found out the big exciting discovery from my strike was that there are other galaxies other than out was either a deal and the structure of galaxies and the way they form us topic of extreme interest which we are just going to skip the only. The only thing I wanted to remind you is a discovery of dark matter that told us that 90 or 95 percent of everything around us is stuff we haven't seen. Speaker 300:04:08And what this graph shows you is a slightly dated version of the limits on the mass units. I promise you that particle physicists measure massive units of energy if you will. If you were to multiply by the shirt and G.V. end of the line the electoral votes is a valid approach to get out and vote on assets which is roughly where we expect to show up. And this is the strength of their interaction with normal matter. And of course we expect that to be very small so measures resort at various inspired events both existing and planned naturally. That rich. So these are exclusion zones and. This region is excluded by Gen. copulations talk about today and this neutrino neutrino observations and the direct detection. Of course the weaker the interaction with matter and for that of the object is the harder the less of a signal you have. Speaker 300:05:19So pushing this foreigners very difficult experimentally but as you see people are starting to not know what they've got and pretty soon if this goes Artley nobody detects anything we'll know that went so wrong and then we'll have to rethink all of them. Speaker 600:05:33So that would be really exciting. And I guess that line was there a problem to the right of any of those one liners are the region in which we existed that existed without you know their identity. Speaker 300:05:49And you know other problems if they existed with that dist
