  • ahha cutest outtakes ever.

    

  • why is it that when we try to explain gravity as curved spacetime and study its effects that our model is always a fabric which stretchs to a "heavy object" and a smaller object's path is alter by that curve. But isnt this example self defeating since the strength and effect of the curve of the stength of the gravity in the demonstration caused by the strength of the gravity on earth?

  • Could dark energy be the quantum fluxuations

  • we will neither learn all there is to learn or cease to attempt to. the beauty of the "human condition paradox" if you will. We are the universe's self observation experiment.

  • i think the universe may be expanding faster than the speed of light. .. i think... thats pretty fast!

  • brillient stuff! very interesting! you have added to the expansion of ones mind. however why isn't the space in my lounge room ripping apart because of the dark energy...which makes up most of the universe i..e 73 % and we have never observed it. go figure. maybe the mysterious dark energy is actually about a hundred or so different things beyound our very limited comprehension. ...still why isn't the space in my louge room expanding before my very eyes and contributing to ones universe.

  • A thing that always bothered me is that if space was stretching, as is always demonstrated, we wouldn't observe the universe as flying apart. For light to experience extra distance space has to be multiplying, extra space is being generated if you will.

    And the curved space around massive bodies - why is it possible break the curved trajectory around a planet for instance? As if there is another force acting in the curved space and not the curvature itself, you couldn't escape curved space.

    So?

  • @mustgetlife the other force is the energy released by the crafts propulsion system, it would not escape without it.

  • @saganemc2 Let me rephrase it. If you look at the ball-on-a-cloth analogy, there's gravity providing the force, making the cloth a potential surface. Let's say I'm able to imagine 3d space stretched like that, doesn't there need to be a force to make this deformation a potential surface? Or does gravity somehow do both? If mass is acting to deform space, why should this deformation be a potential surface? I don't think this can be explained through youtube coments :) thanks anyway for the reply.

  • Great! Another lame explanation of how "space" curves. -The explanation is no explanation, it's a demonstration. There has been no new insight into how to explain this since Einstein... Lame, lame =)

  • @gnimmelfYT I agree, infact, i think everyone is still confused because of Einstein. I don't think he got it right, for one, he never incorporated the fact that bodeis in space (i.e planets, stars, galaxies) are not static, but that there is spin and alot of it.

  • Great Videos!

  • Informative as this is, I can't help remarking that the first thing that came to my mind is that this gentleman bears an uncanny resemblance to Senator Palpatine/Darth Sidious from Star Wars. :P

  • Don't you think that if that theory would be right: two massive objects separated by a log distance in a large space "sheet" would get a point in which no one would attract each other any more? If you make your experiment with two spheres of the same size and keep them as distant as possible they will deform the space but they will not fall into each other. :)

  • haha, love the last sequence ^^,

  • My science teacher told me between partical was nothing me had to guess and I guessed energy he said wrong it's nothing untill now I beloved him carnt wait to get back at him with your great infomation

  • More people need to see this. Although I know it's not really productive to teach someone something before they have the capacity to learn it, I think that this should be taught at a much younger age. I feel almost as if I've been lied to by my teachers about space, gravity etc. Even just a basic explanation of a complicated system is better than saying space is nothing when there's evidence that proves otherwise.

  • why don't you make more videos professor Russell? PLEASE, PLEASE don't stop at the ones already uploaded (I'm watching them almost every night before going to sleep, on my smartphone), I NEED more of these wonderful and insightful explanations

  • i love how we all have this common interest on the nature of the universe.. and we are such a small number of people

  • I'm going through all of these. I like your style! 5/5

  • Russel u mad professor! lol

  • naughty Russell trying to pop this Universe, maybe I should move to a different Universe, LOL

  • Amaxing! :D Like it very very mutch! /greetings from sweden
