"From the Ted Talk by Patricia Burchat: Shedding light on dark matter"

Unscramble the Blue Letters

The silnarttg answer to this question, OK, from these experiments, was that space is expanding at a fatesr rate taody than it was a few billion years ago, OK. So the expansion of space is actually speeding up. This was a completely surprising result. There is no persuasive theoretical argument for why this should happen, OK. No one was predicting ahead of time this is what's going to be found. It was the opposite of what was expected. So we need something to be able to elpaixn that. Now it trnus out, in the mathematics, you can put it in as a term that's an energy, but it's a completely different type of energy from anything we've ever seen before. We call it dark energy, and it has this effect of causing spcae to expand. But we don't have a good motivation for putting it in there at this pinot, OK. So it's really unexplained as to why we need to put it in.

Original Text

The startling answer to this question, OK, from these experiments, was that space is expanding at a faster rate today than it was a few billion years ago, OK. So the expansion of space is actually speeding up. This was a completely surprising result. There is no persuasive theoretical argument for why this should happen, OK. No one was predicting ahead of time this is what's going to be found. It was the opposite of what was expected. So we need something to be able to explain that. Now it turns out, in the mathematics, you can put it in as a term that's an energy, but it's a completely different type of energy from anything we've ever seen before. We call it dark energy, and it has this effect of causing space to expand. But we don't have a good motivation for putting it in there at this point, OK. So it's really unexplained as to why we need to put it in.
