Civet II the explanation for gravity is that matter bends space and so you put mass in a place in space at warp space-time and objects are not feeling the force of gravity they're just following the natural curvature and so this is a sheet of lycra where do you get this is my old bike shorts no there's literally a spandex calm you can get a sheet like this if you buy the stale stuff so you don't care what it looks like right for like 20 bucks maybe less depending on the sale and so you put matter and it warps space-time and so if I have another object it also warps space-time they feel that and they're attracted to each other and so that's that's Einstein's picture grab objects workspace I feel that curvature and move accordingly and if you have more mass you have more mass is going to bend space-time more and so you put something there now it's attracted now in reality that big mass would feel the warping of space-time by the Marvel - right and would move a little bit we usually usually ignore that you know the earth makes the Sun move a little bit but it's so small we can ignore it the moon makes the earth kind of wobble around the point three quarters of the way from the center of the earth we usually don't account for that when we're looking at satellite motion well instead of just letting go of one what if I give it a sideways push now it orbits now it's losing energy which wouldn't happen in the solar system right not noticeably there's some perturbations from other planets and things but this one does lose energy in spirals in if I don't push it as hard it will do an ellipse Music and when he study the solar system all the planets are growing around the Sun the same way why is that that God decide the only life clockwise or as I'm where he's above or below the solar system right why is everything going in the same direction well the answer is it wasn't different directions but there was a preferred direction this is formed from had a slight preference one way versus another and things go in the opposite way got eliminated and when it's all said and done everything's going the same way that usually that works 90% of the time and so I have slightly more in one hand and another vital consciously do that and you want to give them so they spread out a little and yeah the wrong way get eliminated right now there also would have been you know this is where this analogy breaks down there's you know another dimension right but those things are out of the plane also that weren't near the preferred plane also got eliminated and so that's kind of cool now my students use a pH et Phet simulation called my solar system and so they've seen all this on the computer and when we do this during our special relativity unit they're like he is just like the computer that's kind of cool that a stretch see the micro model sings suicide just like a bit similar to the computer now some things we've discovered using this I'll say it's just some larger marbles my friends with them out but they've bend space-time to right and so maybe you can get one thing so the earth-moon system maybe and so you see that this seem you know you can't buy micro this big you get it in rolls and you have to stow it together I've been told to use stretchy string the stretchy thread to sew it together and so the next time I do it I'll do that because it pulls and so you just a little bit of thread fixes it and so in the morning when I first set this up look at leaning against the table I'll be underneath fixing holes from last year one time my principal walked in and I hear somebody in the room and I'm underneath on the middle sewing in a little pause yeah and then he's looking around for me and he kind of those somebodies into remedies oh there you are because what are you doing there and I go I'm repairing a rip in the fabric of space-time you've probably seen plastic ones of these right the Discovery Center Children's Discovery Museum in San Jose has won the Exploratorium has won sometimes they have much shopping malls you put money in it but one thing you can't do with those is put two masses in and so when we went to the moon when we first started we set our spaceship so I'm going to call free return trajectory x' so they would go to the moon and this is hard to get down and they would come back and like a figure eight and so that lets you show now of course the moon lot smaller but if you look at the plots of the free return trajectory back from the Apollo program you'll see it has a figure eight sort of shape and so this takes a little bit of practice to be able to do the figure eight these clamps around here you can adjust it to make it tighter if it's not working so Steve and I when we set this up in the morning we played around with it and actually it I think it was working better than usually is it's not easy and so I go through that's one year a kid who read some stuff about the dark energy energy extra energy what is that makes everything come apart right and so dark energy would be stuff goes apart rather than toward it so if you could work in dark energy anytime and so I.
