"From the Ted Talk by Henry Lin: What we can learn from galaxies far, far away"

Unscramble the Blue Letters

So, one particular question that we have is, how does dark energy affect the universe at the largest scales? Depending on how strong it is, maybe structure forms faster or slower. Well, the problem with the large-scale structure of the universe is that it's horribly cpemoaclitd. Here is a computer simulation. And we need a way to simplify it. Well, I like to think about this using an alanogy. If I want to understand the snnkiig of the Titanic, the most important thing to do is not to model the little positions of every single little piece of the boat that broke off. The most important thing to do is to tacrk the two biggest parts. Similarly, I can learn a lot about the uenvsrie at the largest slaecs by tracking its biggest pieces and those biggest pieces are clusters of galaxies.

So, one particular question that we have is, how does dark energy affect the universe at the largest scales? Depending on how strong it is, maybe structure forms faster or slower. Well, the problem with the large-scale structure of the universe is that it's horribly complicated. Here is a computer simulation. And we need a way to simplify it. Well, I like to think about this using an analogy. If I want to understand the sinking of the Titanic, the most important thing to do is not to model the little positions of every single little piece of the boat that broke off. The most important thing to do is to track the two biggest parts. Similarly, I can learn a lot about the universe at the largest scales by tracking its biggest pieces and those biggest pieces are clusters of galaxies.
