Consider everything we've discussed so far on this list - the gigantic suns, the supermassive black holes, the faraway galaxies, the millions of new stars that are born every day. It's a lot of stuff, right? Well, that only accounts for 5% of the universe. At most. Everything NASA - along with every scientist in human history - has recorded amounts to that tiny percentage of what makes up the universe. Of the rest, 70% is dark energy, and a further 25% is dark matter.
So, what is dark matter? Well...we don't know. We're still working on the theory. We know it's there, because of the way that its mass affects gravity, and without it, there are a number of galaxies that would lose form and spin apart, but that's all we know about it. It's called 'dark' because it doesn't respond to any of our telemetry and it doesn't emit any light or radiation, making it incredibly difficult to detect.
Celebrities are no strangers to changing their looks for a role. And in some instances, they have to get pretty extreme. From 500-calorie-a-day diets to drinking pints of ice cream, Actors and actresses know what it takes to change their bodies in preparation for a new film.
Charlize Theron is no stranger to gaining and losing weight for movie roles, as we remember her transformation in Monster. Charlize Theron gained close to 50 pounds for her role as Marlo in Tully. Theron said that “for the first time in my life I was eating so much processed foods and I drank way too much sugar. … I remember having to set my alarm in the middle of the night in order to just maintain the weight.”
You’re used Chris Hemsworth's hulk-like figure in Thor, but In the Heart of the Sea required a totally different diet. The movie required the cast members lose a ton of weight to make their stuck-at-sea plight more believable. Chris Hemsworth said there were days when all he ate was one boiled egg, a couple of crackers, and a celery stick.
Anne Hathaway wanted to get serious for her role in Les Misérables, as she was playing Fantine, a starving prostitute with tuberculosis. So Anne Hathaway went on a diet of “rabbit food” to drop 25 pounds. Hathaway explained her diet was essentially just starving herself, but she didn’t want to give details, as she doesn’t want to encourage anyone to copy her emaciated look. She did note that she “just had to stop eating for a total of 13 days shooting,” however. And at one point, her bones became so frail that she reportedly broke her arm.
Matthew McConaughey's portrayal of Ron Woodruff in Dallas Buyers Club, a man with HIV/AIDS, was spot-on, earning him the title of best actor at the Oscars. But it also required a serious physical transformation. Matthew McConaughey said he lost 38 pounds for the role. During filming, he said he lost a lot of energy from eating so little — and he hit plenty of plateaus along the way. Finally, with a strict diet, he got down to 143 pounds. And while he did cardio to help with the weight loss, he said it was 90% what he was eating and portion size.
Hilary Swank had to put on 23 pounds of pure muscle for her role as a boxer in Million Dollar Baby. The process doesn’t sound easy, however. “I started working out five hours a day — I had to eat 210 grams of protein a day,” Swank said. She also mentioned that she had to consume 60 egg whites per day, and when that proved too difficult, she had to drink them. And to keep the muscle on, she would get up and drink protein shakes in the middle of the night.
