  • 1:36 look at his left hand and the birds behind him... sorry i'm bored (not because of Tyson, he's great!!)...

  • Comment removed

  • :0 if you wanted to learn more stuff like this after high school..what would u have to do?

  • @XbladeDragon Take classes in related fields I guess. Astronomy, physics, etc. Maybe your college will offer a major that has something to do with space. Ask your advisor.

  • Dr. Tyson DeGrasse is an absolute inspiration to us, the minorities. He is just so awesome and it's always pleasing to see him on tv :).

  • @mmmodafoca He inspires us white folk, too. Awesome fellow.

  • boring questions..

  • theres always a pessimist around. Can't ever be happy with what is given.. tsk tsk..

  • @mmmodafoca I'm not a pessimist. I'm very well informed realist =)

  • I want his tie.

  • It's depressing that the main reason the USA put a man on the moon was for military prowess (to show up the USSR), not to put a medal around the neck of the Human race (although that was a result)

  • cool channel

  • A relay station system to Mars would be very interesting assuming we could even put enough of them cheaply and accurately between the orbits of Earth and Mars.

  • In space, there's a vacuum right?There's no gravity...

    I'm curious, how does a ship use to propel itself forward?

    What does it push away from?

    :-) Anyone know?

  • I imagine it's Newton's laws at work. You fire loads of fuel in one direction and that pushes the spaceship with an equal force in the opposite direction. The fuel doesn't push away from air, but it pushes against the space station, sorta, hehe. It's like the hypothetic scenario of the astronaut that is floating away from the space station and is holding a hammer, so he throws the hammer in the opposite direction to float back towards the station. :)

  • @TousVous Every action has an equal and opposite reaction. Push one way and and you get pushed in the other direction with an equal force. This is much more evident in a low gravity environment, like space. The fuel isn't pushing against anything, it is leaving at speed therefore it is exerting a force in the opposite direction. Rockets dont push against the ground or air when they launch, they just push as much thrust as they can downwards to propel them up. Like rifle recoil.

  • Nuclear reactors on spacecraft FTW

  • Y'all should chill jeez

  • have they addressed the issue of interplanetary radiation?

    my understanding that the best ideas so far were absurd at best and impossible in most cases, to protect the astronauts from extremely lethal doses

  • What the fuck are you talking about ??? Tyson is the most entertaining, intellectual and the most down-to-earth (pun intended) public figure out there. What makes you think he has a huge ego ? He looks like a humble guy. And even if he does have an ego, HE'S AN ASTROPHYSICIST MAN !!!! There are barely a few thousand astrophysicists in the world. He's literally ONE IN A MILLION. If he is a little flamboyant,so be it.Once you become smarter than him, than you will have the right to judge him !!!!

  • Comment removed

  • You are legally retarded and your opinions are baseless. There is difference between being flamboyant and having a huge ego. He doesn't brag about himself, he brags about the accomplishments of science and astrophysics, which are certainly "bragworthy". If those are the signs of an egomaniac, then you need a dictionary. What are you, some kind of school kid ??? Are you trolling or something ???

  • Thanks for answering my questions. Now I am certain that you are legally retarded and mentally equivalent to a 5 year old. You will obviously never manage to achive noteworthy intellectual greatness like tyson or myself, and thus your envious sentiments have made you resort to ad hominem and empty rhetoric. P.S Yes, my lips are attached to tysons ass, and to be honest, it feels like I'm kissing your mom !!!!

  • @Guakamola

    You're welcome. We retarded 5-yr olds salute your intellectual greatness! But U know what? It doesn't help your case 2 claim maturity & intellectual greatness, then make spelling/semantic errors in that very comment! In closing U attack my mother. RE: Your lips on my mom's ass, well, she DID mention she felt an irritating pimple on it. I guess that must have been you. You're stupid, arrogant, hypocritical, full of himself & shit. You're just a fool & I don't suffer fools. We're done.

  • Regarding AKAMOLA (Guakamola to me)

    CORNIZZLE36 wrote as a Channel Comment about AKAMOLA on his/her/its channel:

    ==============================

    "You are disgusting. You have no right to send vulgar messages like that. I sincerely hope that you will begin showing more respect for other Youtube users."

  • Great, now you have proven that you don't even know what a syntax/semantic/spelling error is !!! Well done, every time you post a comment, you keep degrading yourself. You can't read anything properly, your analytical skills are peccant to say the least and you are so desperate that you actually posted a comment from my channel onto this page !!!! What can I say, you have defeated yourself !!! Good day FUCKFACE !!!!

  • gaaaayyyyy

  • Don't pack your house keys... just in case your luggage is lost. You might have to break into your house on your return.

  • Pretty mundane question, but I guess you have to start somewhere if you have never heard this stuff.
