For example, a 6-ounce broiled porterhouse steak is a great source of proteinâabout 40 grams worth. But it also delivers about 12 grams of saturated fat. (3) For someone who eats a 2,000 calorie per day diet, thatâs more than 60 percent of the recommended daily intake for saturated fat.
As we learned in a previous video, there are 100 to 400 billion stars in the Milky Way and more than 100 billion galaxies in the Universe â maybe as many as 500 billion. If you multiply stars by galaxies, at the low end, you get 10 billion billion stars, or 10 sextillion stars in the Universe â a 1 followed by 22 zeros.
There are possibly 80 billion galaxies in the universe, so that means that there are about 4Ã1068 Ã 8Ã1010 = 3Ã1079 hydrogen atoms in the observable universe. But this is definitely a lower limit calculation, and it ignores many possible atom sources such as intergalactic gas.
