Laurie Santos: A monkey economy as irrational as ours
Overpopulation for sure, so there would be no abundance any more. Also if there would be abundance, nobody would be motivated to produce anything, so economic collapse would also happen. Also the other problem is, there must be some inequality: If there is 5 girls and 5 boys at the table, I guess almost all the boys will go for the same girl, and reversed, all girls will go for the same boy. And nobody likes to be second.

Patricia Burchat: Shedding light on dark matter
It's red shift: We did not use tapes to measure the distance to galaxies. It would be too troublesome. It's like when a car moves past you, you'll hear its sound higher when it approaches, lower when it moves away. The same is true with light emitted by the fusion reactions in a sun. And those reactions emit very specific frequencies, so we know where they should be. Now, they are not exactly there. Ok, so it's moving away. But surprise: Everything is moving away. So either we are the center of the world, or everything is moving away from everything. Well, finally humanity somehow managed to resist the temptation to call itself the center of the world, so here comes in the expanding universe theory.

Brian Greene: Making sense of string theory
Moon is moving straight in it's own inertial system, yet moving in circles looking from the Earth. To understand, just get a paper, and draw a straight line. Then roll up the paper: The line is still straight, yet it forms a circle. Or you can use a trampoline and a ball: If you sit in the middle, the ball is moving straight on a curved trampoline, which will form a circle. Of course gravitational pull can be explained with an unseen force, but time distortions and advance of perihelion cannot. So as Einstein suggested, instead of space is flat and planets are going in circles, the space is wrapped, and planets are going straight. And now with the introduction with spacetime, finally the constant speed of light made sense! http://en.wikipedia.org/wiki/Mercury_(planet)#Advance_of_perihelion I don't get what you wanted with the meteor, so can't answer that. Sorry about that.

Joachim de Posada: Don't eat the marshmallow!
Follow up study: Kids were distributed randomly as control and "real" group, and they've been told, they have to wait ten minutes to get a big painting kit, or they can get the small one which is already available. But after ten minutes, the "real" group has been told, that unfortunately there is no big painting kit available atm, while the control group did get a big painting kit as promised. Then the next day the famous marshmallow experiment were made: Kids in the previous day control group were more likely to choose not to eat the marshmallow than the prev day real group. It's all about security: Ten thousand years ago, we were living in caves. If we had some leftover meat, it not only got rotten, but it's smell attracted night predators inside. So we had to eat it asap and store it as fat. While if we had a strong clan, and the protection of the cave was solved, we had to leave for the others, so they can do their job, like protecting the cave and food and our children, while we're out hunting. They did not eat the marshmallow because they were greedy. That's just their evil parents' propaganda to blacksheep the children, to make themselves look better next to them. They eat the marshmallow, because their trust in society consciously or subconsciously was broken. We call this "social capital". And it can be found, that groups of society that is less successful than others have less social capital than others. It works like: "I will betray you because I know you'll betray me anyway!" - This is a Nesh equalibrium: Neither party gains advantage by changing his tactic, but each would gain if each would change. Those kids' parents should be hanged: They probably beaten their kids, and when the kids asked why, they replied: "Because the world is unjust, and I beat you again because you talk back!" They not only damage their own kids, but those kids will grow up, will damage other people, and the whole society.

Chris Domas: The 1s and 0s behind cyber warfare
But even then this is only usable, if the processor, the OS, the image format is all prototype, and the text is russian or chinese or something... But even terrorists buy all stuff from the store. Ok, might be good for hacking a new russian missile or satellite, but I think even those will use the x86/x64 architecture, and might be windows... or not windows - in that case it would just crash by itself. :D But even then, up to date encryption will still be a problem.

Chris Domas: The 1s and 0s behind cyber warfare
No WireShark?! And how does encrypted or compressed data looks like?! And even in the old days there were disassemblers and debuggers. That was the only thing crackers were using till encryption and other fancy protections came in.

Ray Kurzweil: Get ready for hybrid thinking
Why say anything to anybody when each of you are connected to the cloud? I think we'll be the Borg if this works. Like a giant ant farm. But I hope, brain uses quantum information, which are effectively unaccessible by anything. Nature have already surprised us a lot of times times using tech for ages we thought we'd just invented.

Nicholas Negroponte: A 30-year history of the future
Then mine too. :) As a quote from Outer Limits - The Human Factor says: "The only thing that has saved the Earth from complete annihilation is the fact that you have nowhere to run to. That is about to change..." So as cheap power, either nuclear fast breeder or fusion becomes available, overpopulation will become a more serious problem. Then the rich will hide somewhere, either space or underground, and switch down the lights behind themselves. The only thing that can "save" Earth, if we find some bigger enemy than ourselves. Well, but that's not saving at all.

Michel Laberge: How synchronized hammer strikes could generate nuclear fusion
Ok, but a calculator is a delicate equipment: No moving parts, no heat generation, no fans for heat dissipation. When you need a car, or you need to heat up your home, or heat food, or you might even need an airplane, you'll need much more energy. And that's why sby found out to put them along the equator. Yes, they are lacking the will. But equator is still not a good place for solar panels. And we should seriously think about other forms of solar generator, or even other renewables, because I think solar panels are partial solution at best.
