Unscramble the Blue Letters

Now, you can do an experiment tonight over the reception, OK, to figure out what that image will look like. Because it turns out that there is a kind of lens that we can devise, that has the right hesap to produce this kind of effect. We call this tnlgraiotaavi lensing. And so, this is your nnitmerust, OK. (Laughter). But ignore the top part. It's the base that I want you to concentrate, OK. So, actually, at home, whenever we break a wineglass, I vesa the bottom, take it over to the machine shop. We shave it off, and I have a little gravitational lens, OK. So it's got the right shape to produce the nnsielg. And so the next thing you need to do in your experiment is grab a napkin. I grabbed a piece of hrpag paper — I'm a physicist. (Laughter) So, a napkin. Draw a little ldmoe aaxygl in the deidml. And now put the lens over the galaxy, and what you'll find is that you'll see a ring, an Einstein ring. Now, voem the base off to the side, and the ring will lipts up into arcs, OK. And you can put it on top of any image. On the graph paper, you can see how all the lines on the graph paper have been dotrtisde. And again, this is a kind of an accurate model of what happens with the gravitational lensing.

Now, you can do an experiment tonight over the reception, OK, to figure out what that image will look like. Because it turns out that there is a kind of lens that we can devise, that has the right _____ to produce this kind of effect. We call this _____________ lensing. And so, this is your __________, OK. (Laughter). But ignore the top part. It's the base that I want you to concentrate, OK. So, actually, at home, whenever we break a wineglass, I ____ the bottom, take it over to the machine shop. We shave it off, and I have a little gravitational lens, OK. So it's got the right shape to produce the _______. And so the next thing you need to do in your experiment is grab a napkin. I grabbed a piece of _____ paper — I'm a physicist. (Laughter) So, a napkin. Draw a little _____ ______ in the ______. And now put the lens over the galaxy, and what you'll find is that you'll see a ring, an Einstein ring. Now, ____ the base off to the side, and the ring will _____ up into arcs, OK.

Now, you can do an experiment tonight over the reception, OK, to figure out what that image will look like. Because it turns out that there is a kind of lens that we can devise, that has the right shape to produce this kind of effect. We call this gravitational lensing. And so, this is your instrument, OK. (Laughter). But ignore the top part. It's the base that I want you to concentrate, OK. So, actually, at home, whenever we break a wineglass, I save the bottom, take it over to the machine shop. We shave it off, and I have a little gravitational lens, OK. So it's got the right shape to produce the lensing. And so the next thing you need to do in your experiment is grab a napkin. I grabbed a piece of graph paper — I'm a physicist. (Laughter) So, a napkin. Draw a little model galaxy in the middle. And now put the lens over the galaxy, and what you'll find is that you'll see a ring, an Einstein ring. Now, move the base off to the side, and the ring will split up into arcs, OK. And you can put it on top of any image. On the graph paper, you can see how all the lines on the graph paper have been distorted. And again, this is a kind of an accurate model of what happens with the gravitational lensing.
