• You really expect problems like war, starvation, sexism, racism, pollution, disease, and exploitation to ever be SOLVED (especially in the next 50 years)? We've had these things going on since we first started walking on two legs. The fact that we have issues at home doesn't constitute a reason to stunt progress. Can you imagine if Kennedy said "Oh man, we can't go to the moon when we still have race riots and chicks burning bras! Well....shit"? If "we have too many issues so we shouldn't try to progress ourselves in any other way" was a viable excuse then we'd still all be living in caves. And there's a damn good chance going into space and finding other life forms is what it will take to unite us-staying coupe up on our little planet festering with one another isn't going to solve the kind of issues you're talking about.

• To be fair, getting to moon put us in debt for a couple decade. Bush Sr. and Clinton did a great job getting us out of it. My opinion about either of them aside, they were good economists. Then comes Bush Jr. to fuck it up.

• I think there are some key differences here. I don't believe these people are talking about going somewhere so we can take resources from someone else, impose our doctrine, and increasing our glorious empire. It's just about practical survival. Our entire civilization sits on one rock. Forget nukes and global warming and reality TV. All it takes is a random bit of cosmic grit swinging into our path and it's lights out for the species (most species, actually). We're already struck pretty regularly -- a fairly big blast from 2008 in the Sudan comes to mind. And that asteroid was barely 16 feet across. What happens when a bigger chunk drops out of the Kuiper Belt? Even Michael Bay won't be able to save us. ;-) I say full speed ahead to Mars. Though I (sadly) agree with others here that it's not going to happen anytime soon. Maybe if we're lucky enough to have a civilization-killing rock pass close enough to make us all crap our pants, we'll get it together. More likely, it'll just hit us and we'll have a few hours before hand to reflect on the time wasted bickering over American Idol contestants or Trek vs. Star Wars.

• She's well on her way: http://www.dropnews.net/840/miley-cyrus-says-she-is-hot-and-sexy-like-zac-efron/

• Great video. Although there is something about the "we must expand or perish"-logic that makes me think of evil empires.

• Like!

• Please keep posting these! It's not enough to have them on my mp3 player, I want to see them here too! I'm not kidding, with either statement.

• Don't stop. I love these videos.

• I'm sorry, what have you ever contributed to any major scientific field? I must have have missed it. Bummer.

• Seriously. The only way I can keep track of them is if you post them, Rob.

• Wait, are you saying Miley Cyrus is going to get fake boobs and do a sex tape? Nice.

• Autotune is played out. Carl Sagan's nasal science hippy ashes should be left to rest, in space. I don't care for these clips, Rob, you asked.

• These are great. Post at will!

• Why don't we just burn all of Zheng He's ships? What can the rest of existence offer compared to the perfection of the Middle Kingdom? Besides, we have matters at home I'm sure we'll be able to deal with first.

• Finally!! A useful use for autotune!! This is mystic.

• Definitely keep posting these, because I loved every single one but this one. I agree with some of the other commenters that the U.S. and indeed, humanity does not have its priorities straight. But I really hate the idea of humans going into space when back on Earth we still have war, starvation, sexism, racism, pollution, disease, exploitation, and a host of other ills. I have always loved the idea of visiting other worlds. I have always loved science and science fiction. I just think visiting Mars is something not for 10 years from now, but for 50 years. Or maybe even 500 years, considering how long it usually takes humanity to make progress.

• If you didn't post these and somerandomguy's videos.. then i would have no reason to visit your website. The only thing else that's offered here is Transformers video game trailers and erotic pokemon stories.

• DON'T. EVER. STOP. POSTING. THESE.

• I love these things. Several of the first ones made me tear up. Life is so amazing, sometimes you forget what is right under your nose.

• I love these things.. I've downloaded all of them! I wish there were more people like Carl Sagan in the world

• I found out that this was out just before I clicked here and the first thing that I said was "Why the Hell didn't Bricken tell me this shit? It's been a week!" I would say just kidding but I really did say that.

• I feel like we're never going to make it to Mars at the rate we're going. We just wont put the funding into it. We pay billions of dollars to completely useless people (starlets, anyone with fake boobs and a sex tape, Miley Cyrus) but NASA has been struggling with budget cuts for decades. We don't have our priorities straight at all. I remember an astronomy teacher telling me last year that IF we go to Mars, the people going are currently in junior high school/elementary school. And that's under the best conditions. It seriously depresses me that the moment we went to the moon and "beat the communists" everyone stopped caring about space exploration. And don't even get me STARTED on the people who don't believe we even did that...

• <3

• That is just really awesome!

• Beautiful...! Of course, at the rate we're going, the first human on Mars is going to be working for either the PLAAF or Google.

• Keep posting em please. I love them and it's great to have a notice when a new one is out.

• If you mean the scientist and not the Scottish actor, then you are correct. And I'm a guy!

• I haven't watched them (yet), but anything with Carl Sagan in it is fine in my book. Keep them coming!

• The one dude was talking about how if we don't got to Mars, we risk stagnation and decay. Isn't that already happening? In the beginning of the 1960's Kennedy said the USA was going to go to the moon, and in 1969 they did. Now, the USA can't even attempt to guess when they will fix problems like the Debt or over reliance on fossil fuels, never mind a major manned space mission.

• Please nevereverever stop updating us to new ones.

• Yeah, Carl Sagan's just about my favorite human who ever lived, and even though I have the Cosmos series box set, I can always stand to see him online talking about what he loved most.

• Brian cox is hot...

• Although he did say in his Twitter he's thinking about doing one on dinosaurs, and who doesn't love dinosaurs?

• I don't mind them, but I think the two first ones were the best (and totally awesome) and the rest are only okay.

• &#64;Bricken, If you're happy, we're happy.

• I love these. You should never stop showing them.
