"Science geeks, rejoice \u2014 Reddit AMAs featured a treasure trove of nerdery this week.\nAstronaut Buzz Aldrin, a group of paleontologists and Boba Fett \u2014 a.k.a. actor Jeremy Bulloch \u2014 rounded out some of the most interesting Reddit moments.\nSee also: 15 Fascinating Reddit AMAs You Need to Read\nFor all of you adrenaline junkies, other great AMAs include Mike Tyson, the 24 showrunners and the director of Dawn of the Planet of the Apes, Matt Reeves.\nWe've compiled some of the best moments below.\nBoba Fett\n\nVideo: YouTube, Inside the MagicJeremy Bulloch, who played Boba Fett in the original Star Wars trilogy, answered Reddit's questions about on-set memories, cosplay and how weird is too weird when it comes to fans' methods in revealing their Boba Fett tattoos. When asked about a behind-the-scenes memory, Bulloch revealed a funny story about losing his footing with Darth Vader.\n\n\"I think one of the funniest was when we were rehearsing the carbon-freezing scene. I was treading on Darth Vader\u2019s cape and we fell over and two of the biggest villains were floundering on the floor. We looked like two silly children. \nThere\u2019s lot of fun moments actually. Under a mask no one can hear you. There\u2019s a part where I turn to an Imperial officer and say, 'Put Captain Solo in the cargo hold,' but I actually said 'Put Captain Cargo in the Solo hold.' Luckily I didn\u2019t have to tell anybody because you can\u2019t hear what I\u2019m saying under the mask. But I didn\u2019t have any lines ... How on earth with so few lines could I make a mistake?\"\n\nBuzz Aldrin\n\nImage:  Nasa ImagesMoonwalker Buzz Aldrin came to Reddit to talk about Apollo 11, space and the most important advancements in human history. You know, moon-sized ducks and duck-sized moons. When a Redditor asked Aldrin what he believed would be the next great human achievement, he spoke about a Martian colony.\n\"There is very little doubt, in my mind, that what the next monumental achievement of humanity will be the first landing by an Earthling, a human being, on the planet Mars. And I expect that within two decades of the fifth anniversary of the first landing on the moon, that within two decades America will lead an international presence on Planet Mars. Some people may be rooting for Elon \u2014 I think he could, with his SpaceX, contribute considerably, enormously, to an international activity not only at the moon but also on Mars. I have considered whether a landing on Mars could be done by the private sector. It conflicts with my very strong idea, concept, conviction, that the first human beings to land on Mars should not come back to Earth. They should be the beginning of a build-up of a colony / settlement, I call it a \"permanence.\" A settlement you can visit once or twice, come back, and then decide you want to settle. Same with a colony. But you want it to be permanent from the get-go, from the very first. I know that many people don't feel that that should be done. Some people even consider it distinctly a suicide mission. Not me! Not at all.\"\nMike Tyson\n\nImage:  Funny or DieUnlike many celebrities who answer Reddit's questions, Tyson didn't shy away from many tough ones. He commented on a question about Luis Suarez's World Cup bite with something of an explanation for his own famous ear chomping experience.\n\"I think it is just the heat of the moment, really hot blooded and really competitive. The heat of the moment takes over us, we are really competitive and lose bad judgement in our thinking. Sometimes you can just become highly frustrated.\"\n\n24 showrunners Evan Katz and Manny Coto\n\nVideo: YouTube, Buddy TVWith the finale of 24's reincarnation set to air on July 14, writers and showrunners Evan Katz and Manny Coto answered fan questions on Reddit. Coto revealed that he had a few regrets about the direction they went in Season 6.\n\"In all seriousness, there are great moments in Season 6. Jack torturing his brother is one of the highlights of the series, but we do think that it went in a bit of the wrong direction. If we had to do things over, I think we would have changed course.\"\nThe Dino Guys\n\nA group of dinosaur experts \u2014 Dr. Robert T. Bakker, Matthew T. Mossbrucker and \"Jurassic hotel\" owner Greg Tally \u2014 who also happen to double as Tolkien experts came to Reddit to, well, geek out about dinosaurs and Tolkien. The trio answered from separate accounts, but Mossbrucker won the day with an answer to \"What's the best dinosaur?\"\n\n\"Not Lambeosaurus. I have known many L'saurs in my time, and they are the Chad of dinosaurs.Thank you for this question. It is time to set the record straight.\nPlus, Stegosaurus kicks ass.\"\n\nMatt Reeves and Michael Giacchino\n\nImage:  Fox MoviesThe director and composer of the upcoming Dawn of the Planet of the Apes gave Redditors an inside scoop on the film and their experience with the Apes franchise growing up. A shocking moment came when Reeves revealed how much it costs to render about five seconds of the CGI apes.\n\"...they rebuilt everything from the ground up for Ceasar to make it better. WETA sort of makes an overall deal, and tries to give you the best value they can give you, but there were 1,000 artists working on the film, and the overhead for that is basically a small village, so it works out to roughly around somewhere to $50-60,000 per five seconds of a shot of apes. Broadly, broadly.\"\nHave something to add to this story? Share it in the comments."^^<http://www.w3.org/2001/XMLSchema#string>
