0:00.0	Hey, everyone. This is once again your friendly neighborhood cosmologist, Katie Mac. I am
0:07.6	giving a little bit of an update to this episode. This episode is mostly answering questions about
0:14.4	astrophysics and cosmology things. And since it was recorded in 2017, there have been a couple of changes, a couple of updates.
0:22.0	One of the things that I answered questions about was asteroid searches. And I mentioned that there is a big part of this guy
0:28.9	we're not really looking at. That has gotten better in recent years. There are some new observational projects.
0:36.2	We have a much better survey of the sky for finding potentially dangerous
0:42.8	space rocks. There's some caveats though. One of them is that because of things like these new
0:49.6	constellations of satellites that are going up, some of that is making those observations a little bit
0:55.5	more difficult. I think we're still in a much better place than we were and we're finding way more
0:59.6	potentially hazardous objects. Nothing is a big threat at the moment. Don't worry. But yeah,
1:05.2	it'll be interesting to see how that develops in the next few years. The other update is just that my
1:10.4	social media stuff is all different now. I'm still on Twitter as at Astro Katie, though I'm using
1:16.8	Twitter less these days. I'm on Instagram at Astro Katie Mac. So check those out and just check out
1:23.6	my web page astro Katie.com that hasn't changed. You can learn about stuff like my book, the end of
1:28.8	everything astrophysically speaking, where I talk about how the universe might end and what that would
1:33.6	look like if we could see that. And I have a newsletter now that you can also check out. There's a
1:38.8	sign up on my website. It's called Watch This Space Time. So thanks for listening and I hope you
1:45.2	enjoy the show. Hey, this is Ali Ward here with Allegis. Now a few things up top. If you like
1:53.6	Allegis, I personally myself would love it. If you took a second to rate and or review it on iTunes,
2:01.8	have you done that yet? It doesn't cost any money. You just do it. And I also totally read all of
2:06.9	your reviews. I'm thrilled by them. Today someone named Smile Miss, there are six S's in that,
2:13.2	said the actual best. Yep, the actual best. When things get all jargony, Ali fills in the gaps.
