Terraforming mars has been a topic on science fiction for decades, but it is actually possible. There are still many problems associated with it and one of the biggest issues of transforming the Martian atmosphere is heavily based in physics. I don't hear this mentioned very much, but that's what we talk about this week. Follow us on twitter @moreabstract Outro by Eric Pierce

How was it that earliest civilizations suddenly disappeared. During the bronze age, there were complicated interconnected societies most of which collapsed over the course of a few centuries. We talk about some of the leading theories that lead to this collapse. Follow us on twitter @moreabstract Outro by Eric Pierce

How do we tell when an asteroid is going to hit the earth. It's a difficult task with very few prediction. We talk about all the problems with trying to identify an asteroid. Follow us on twitter @moreabstract Outro by Eric Pierce

How is it that a new currency can be made out of thin air and used to purchase good. We talk about how to make a currency called sandwich coins and a bit about the system that lends money through banks. Follow us on twitter @moreabstract Outro by Eric Pierce

We've heard from scientists that CO2 is a greenhouse gas that is causing average global temperatures to rise, but that's it. Few people know why that is the case and even fewer know the physics behind this phenomenon, which is surprisingly simple. Here we go through why climate change is just logical physics.

How are old satellites decommissioned. We spoke about this in one of our previous episodes, but didn't go into detail. This episode, we talk about how massive achievements like the Hubble Space Telescope will be decomissioned. Follow us on twitter @moreabstract Outro by Eric Pierce

Just like fusion, hydrogen fuel cells have been touted as being the fuel of the future, but as the years go on that promise never becomes a reality. This week we talk about what fuel cells are and some of the challenges that face the technology along with some of its benefits over conventional electric or gas vehicles.

Perhaps the most consistent question asked about scientific research is why does this matter. It is something each researcher struggles with everyday. That question is important, but it needs to be put into a larger context before its importance can be realized. That's what we talk about this week using two historical examples and relating it to the launch of JWST. Follow us on twitter @moreabstract Outro by Eric Pierce

How were we able to observe a black hole 50 million light years away so clearly. It is a massive undertaking that we talk about this week including why it is such a big deal to the scientific community. Follow us on twitter @moreabstract Outro by Eric Pierce

The existence of market bubbles are not unique to our modern world. They've existed in the past and possibly the first market bubble involved the sale of Tulips. How exactly did the situation lead to a bubble that eventually popped and is it any different from the bubbles we are aware of today? Follow us on twitter @moreabstract Outro by Eric Pierce

Have you ever wondered what it is about a viral infection that makes you feel so terrible? When you're told about some infection, it's usually only the beginning part, where the virus infects a cell, but nothing after that. Nothing about how the body responds specifically. That's the topic of this weeks episode of More than Abstract, join Pranjal and Eric as they tackle this problem. Follow us on twitter @moreabstract Intro/Outro by Eric Pierce

Why is lead bad for us. We all know that it is, but nobody has ever said why though. That's what Pranjal and Eric try to tackle in this weeks episode, why does our body need metals to begin with and why certain heavy metals are toxic to us, instead of simply leaving our system entirely.
