love this channel ok how do i bribe the universe with energy so i can go to kepler 2b
tl:dw God's a loan shark
[QUOTE=SweetTea;51760526]love this channel ok how do i bribe the universe with energy so i can go to kepler 2b[/QUOTE] Easiest (but not in any way cleanest) way would be nuclear pulsed propulsion- detonating thermonuclear shaped charges at a high rate against an armored pusher plate on the back of your ship. However, that's likely not going to be a thing, due to the fact that it's hazardous to other craft in the vicinity and is impossible to use as a launch system without nuking your launch site. Ideally, the best propulsion systems we could use in the near future would be nuclear fission (NTRs, etc.) or fusion-based rockets, but both require a bit of work to get out and in use, and fusion still has a massive amount of progress needed to be viable. The main issue with going interstellar is the time and distances involved- even at a significant fraction of the speed of light, you're either going to need a sleeper ship (requiring some sort of stasis or cryo system to keep your crew alive, in hibernation the whole way), and/or a generation ship (which would be even harder, given that it'd be essentially a space habitat with engines strapped to it that would have to be self-sustaining life-support-wise).

Nuclear propulsion is the future but that won't be around at least another 20-30 years.
How about we all jump and while we're in the air just blow up the planet so we don't have to pay it back?
While its a good video, it felt shallow in content compared to their other videos.
Fuck this gay earth and the gravity loan sharks
[QUOTE=Bradyns;51760725]That's still a terribly inefficient solution.[/QUOTE] This is why we need a space elevator.
[QUOTE=ForgottenKane;51761981]This is why we need a space elevator.[/QUOTE] That's terribly costly and inefficient too with current materials like steel cable and kevlar. Carbon nanotubes *may* make this feasible (See 8:00) however we can't manufacture CNTs on that large of a scale yet. [video=youtube;iAXGUQ_ewcg]http://www.youtube.com/watch?v=iAXGUQ_ewcg[/video]

Fuck you Universe it's [del]2016[/del] 2017
Playing KSP gets you to respect orbital speeds and gravity. Going so fast you can't really change your mind about things is a scary concept.
I learned waay more about rocket science from Kerbal Space Program. I also didn't have an existential crisis this video wtf kurzgesagt.

[video=youtube;iAXGUQ_ewcg]http://www.youtube.com/watch?v=iAXGUQ_ewcg[/video][/QUOTE] Obviously I didn't mean with current materials as if it was feasible we would have done it already. CNTs might get us there, but honestly we're going to make the advancement at some point or another for a material that can withstand the immense undertaking of a space elevator. It's just a matter of when.
[QUOTE=LoneWolf_Recon;51761309]While its a good video, it felt shallow in content compared to their other videos.[/QUOTE] I think this was kind of a necessary video though, since a lot of people don't understand just how difficult getting to space can be. This video did a good job at hammering the idea of "it's fucking difficult".
[QUOTE=ForgottenKane;51761981]This is why we need a space elevator.[/QUOTE] space catapult
I really like this videos, great visuals and informative. But I felt the "debt" analogy was more confusing than the concept it was trying to convey.
[IMG]http://i.imgur.com/1UF7TKB.png[/IMG] This is my idea I think it is the best idea.
Aw, I hoped this video would've had more about deep space travel, like Voyager 1. I wonder what programs they use to make the visuals and sound in these

An interesting idea, though, no doubt. I've always been enamored with the idea of mass drivers.

[QUOTE=abcpea;51765207][IMG]http://i.imgur.com/1UF7TKB.png[/IMG] This is my idea I think it is the best idea.[/QUOTE] Doing that at 5G would only get you to 140m/s or thereabouts (it's been a while since I did physics, though), so you still have some ways to go. Also, you'd probably want a bit of an angle (would give you more time for acceleration as well), maybe even a slope.
What if we put a mass driver on the ground, had it accelerate a stream of matter (e.g. gravel) to cosmic speeds, and pointed it at a spaceship? The gravel hitting the spaceship would provide acceleration through the whole duration of the journey, so it can be much gentler than just shooting the spaceship itself out of the mass driver.
[QUOTE=abcpea;51765207][IMG]http://i.imgur.com/1UF7TKB.png[/IMG] This is my idea I think it is the best idea.[/QUOTE] Why not angle it though? You want to harness those sweet gravity turn savings.

[QUOTE=abcpea;51765734]i think 5G would be 440m/s, plus it is already above 4000m ASL! also it can go straight up[/QUOTE] I'm totally off, literally wrote in "5" as the acceleration, complete brainfart. Doing the calculations again (and properly this time), 440m/s is the correct answer - much more reasonable.
