Hey Guys,

I just wanted to applaud you for your research for the "Science of Firefly" section. Being a Graduate student in Astrophysics with an MS Physics (and a huge fan of the show, of course), I really appreciate the work. I certainly recognize the theories and such and was glad to hear you made it much more than just a fluff piece! Good work!

It is wonderful to hear Greg Edmonson! Thanks for that interview. And I am really, really impressed with how well the Message music came out. You had to put a huge effort into that, and it is very appreciated.

Thanks!

Excellent show, guys and gals.

when the RPG comes out, will you be doing a segment on the game?

Hey guys,

Thanks for another great show. The intreview with Greg was great. I'd love to hear more from people like the clothes or set designers - the people behind the camera are often real interesting.

Thanks for putting out my advert - what with this and ending up on Whedonesque it's been a big week! Smile

I tried to do an interview with Andy Peregrine (one of the co-writers of the FF RPG) but I'm not sure it turned out so good. My suggestion if you really want to make a good one would be to phone him and record it like you've done for your other guests.

Keep up the good work and stay shiny!

For any reader of this thread who hasn't figured it out, I believe Dave is refering to the promo for "Still Flying", a Firefly fanzine which you can get hold of at http://www.stillflying.co.uk

I have to say that that was a really professionally produced promo. You might want to consider trying to get some other podcasts to play it. "The Week in Whedon" are certainly worth a try.

Also - why not put that promo on your webpage?

Just some thoughts.

Hi guys.

I wanted to drop a line and let you know that I really enjoyed #7. The Greg Edmonson interview was one of the best I've heard on your show. I really loved hearing his passion for the show, which so closely reflects ours as fans. Kudos for a great segment. Keep 'em coming!

I was not so pleased however with the science of Firefly section. It was well produced and well thought out, but I have to disagree with the conclusions. Of course there has to be FTL speeds on Serenity. There is no way around it. Unless all the planets in the verse are in the same solar system, you have to have FTL or you are talking extreme travel times. Our closest neighbor, Alpha Centauri, is 4.35 light years away. This would make it about 4.35 years travel time if the vessel were traveling at the speed of light, and that's not counting acceleration and deceleration time. I am not an astrophysicist, nor a rocket scientist (Although I do work at NASA*) but anything exceeding the speed of light has to be considered FTL and so... well you get the point. Since they obviously don’t spend 3-4 years going between planets, they must have FTL... QED.

Thanks for the podcast, I've been listening since show #4 and you guys are getting better and better! Thanks and keep it shiny!

Yours

* quick biographical note:(you guys should have an "Introduce yourself" thread in here somewhere) I'm putting this here since every time I tell people I work for NASA they always assume I'm a rocket scientist. I'm totally not (But I play on on TV! HEY! lol JK). I am a 41 year old TV editor, specializing in high end post-production. I have been at NASA TV, HQ for 4 years and I do most of the big glitzy stuff that can be seen mostly as filler between other programs on NTV. I'm also a big geek who loves space, sci-fi, comic books and gaming. I'm also an amateur musician, which might explain why I liked the Greg Edmunson interview so much.
Thanks again... and they cant take the sky from me...

I'm not the author of the article, but you yourself brought out one reason that Firefly would not need FTL travel: if it is all in one solar system.

I've seen this as a hotly debated topic in some Firefly circles:
http://www.fireflyfans.net/thread.asp?b=4&t=2671

There is a speculative fan-made system map showing the the Firefly setting as a single solar system:

Not to get too geeky (Too late!) but a single solar system would be incapable of containing hundreds of (habitable) planets. If nothing else, gravitational forces would tear many of the planets to peices through sheer force of tides (read Neutron Star by Larry Niven) The problem would be that there is a fairly narrow band of space where planets must reside to be habitable, and if so many gravitational wells were in such close proximity ie. close to or exactly the same orbits, they wouuld tear each other to pieces. 5-10 planets I might buy. hundreds? not a chance.

That is a very cool idea, and I admit it might be possible, but it would not be a stable way to live. All those planets would be massively in each other's gravity footprints, especially at close conjunction. You would have to live with frequent and incredibly powerful earthquakes, tsunamis, storms etc. I'll admit to the possibilty, but I wouldn't want to live there! Laughing

Putting all science aside, my gut instinct really likes the "all in one solar system" model. It seems very cozy and puts it on a more human scale.

We already know that they have artificial gravity in Firefly, and they can aparently do some pretty fancy things with it (changing the gravity of worlds when they terraform them). IMHO their "gravity control" technology is the one huge sci-fi tech leap that the show makes. If they can already do such cool things with gravity, why not mess with orbital mechanics too. With this kind of extreme gravity control technology, we don't need to have a huge advance in another area of physics (FTL travel).

Gelf13--

You and I are in agreement here. Although it's been sufficiently proven to me that the "Whedonsystem" of Firefly does indeed contain about 70 worlds in the same system, thus negating the need for FTL, my willing suspension is severly strained by this and some of the other science seems to break down.

However, because the story is really about people, I'm willing to overlook the science problems. I just tell myself it's really just a fantasy with some of the trappings of SF.

I wondered if there were any other NASA types running around. Ames Research here.

The major problem with your discussion about FTL is that you base it on what one man, Einstein, theorized in the 20th century.

1) Einstein is not GOD, not even related.
2) It took a couple hundred years after a man named Newton to prove that Newtonain physics was only a good approximation in certain cases, and was not accurate under all circumstances. (Newton, much closer to GOD, had to invent Calculas first in order to create Newtonian physics!)
3) After WWII it was believed that travel at speeds above the speed of sound was impossible, based on experiments and the current mathmatical understanding of aerodynamics. Drag appeared to approach infinity as we approached the speed of sound. (An army artilery officer was the first to say hogwash since artilery shells and bullets travelled faster than the speed of sound!)

Our science is always built on proving that previous theories, although having some validity, were not 100% correct.

To say Einstein's theories will hold up to the test of time is ridiculous. The fact that our limited testing of his theores have not yet found a flaw in those theories means nothing. Why would we be experimenting if we knew these theories to be fact? Give it time and you will see Einstein was no more right or wrong than Newton.

What a bizarre thing to posit. Is this based upon empirical data? Perhaps you can point to the publication that put this forth.

There are some who maintain that both are children of God. That would make them siblings with a common Father.

*shrugs*

And Einstein had to invent Relativity to create Einsteinian physics. Your point?

Just keep one thing in mind. Simply because you want FTL doesn't mean that the universe has to bend to your wishes.

I actually agree with the sentiment here. That's why I'm much more willing to suspend disbelief on FTL than a 100+ world solar system.

And btw... Gravity control on a planetary scale? Whoa! Did they actually posit that?

That would be... WHOA! Wink

If you haven't already heard, the "Serenity: The Official Visual Companion" that is coming in September includes a breakdown of all of the planets with their names and how the solar system works. I doubt it will go too far into the science behind Firefly, but it should definitely answer a lot of questions about the solar system.

Here's links to two fan reviews (the first one has a small picture of the planet page):

In one of the shows they say that terraforming changes the gravity of worlds. That is as far as they go. I am the only one I know of who has pushed the theory further. Either FTL or any kind of gravity manipluation will require a fundamental changes from how we understand physics today. We know that they can already do cool stuff with gravity (aparently effortlessly - when Serenity lost power & lifesupport in Out Of Gas it still had gravity). By taking their exhibited gravity technology a bit further I can get away without having to need FTL travel also. I prefer to break only one law of 21st century physics at a time.

Ya know, something to consider when discussing "The Science of Firefly" is the writers, producers, etc. aren't always science geeks like some of us. Some of the Firefly "facts" we're hanging our hat on are undoubtedly things that when mentioned to the creators, they would say "oops, didn't think about that...". I read a post a while ago that at a Q & A Joss himself said "If you ask more science questions I'm going to cry...". It's actually a little funny to think we may be debating ourselves in circles over an oversight or a science inaccuracy the budget couldn't tolerate and was blown off.

Do you dispute the canonicity of the comic books (despite the fact that they were written by Joss)? They state that the 'verse is one single solar system.

If so, here's the trump card. I've seen the movie. And (this is not a spoiler) in the movie they state explicitly and catagorically that there is one solar system containing dozens of planets and hundreds of moons. Is the movie not canonical?

It's not the Signal with whom you want to argue. It's Joss Whedon.

Jill.

There were elements in the science section I refute, but that was one that I'm pretty clear was put to rest.

The one I have issue with is the necessities it would take to terraform and change the gravity of a planet. They have Artificial Gravity (which hopefully the next episode covers), and it's simple enough to remain running even when the rest of the ship has been crippled (sure that was just because it would have been impossible to do the entire episode in zero G, but still), not to mention that a ship that size could even support it. It's reasonable to believe that an entire gravitational feild can be created rather easily around almost any size object. If that's true, they can probably do a similar trick to an entire planet, which in turn could hold onto an atmosphere but not screw up the orbit - think about it, one solar system with a bunch of earth gravity planets floading around? They'd all crash into themselves! So terraforming wouldn't be that hard if you covered the gravity and air production bits (not just plants, gonna need machines that create and pump air into the newly created atmosphere). Neither of which are scientifically sound today, but neither was nuclear power even 100 years ago.

Changing the gravity of a moon by the mechanism described in "The Science of Firefly" does not modify the orbit one iota. The mass and center of gravity remain constant, ergo the orbit remains unchanged.

You're confusing surface gravity with mass. We are not talking about a bunch of moons with Earth's mass, we are talking about a bunch of moons with their original mass, but with surface gravity equal to 1g.

The next part of "The Science of Firefly" will cover it. The next episode of "The Signal" will not. Currently, the concluding part of "The Science of Firefly" is scheduled for show #9.
