Hey my mom makes lasagna all the time and we freeze the leftovers. It will last a good two weeks in the freezer. My advice is to take it out of the fridge and stick it in the freezer. Lasagna is always better the day after it was made, i.e. as leftovers.
Thus, the part of the Universe we can observe (the Visible Universe) lies within a sphere with a radius of 13.7 billion light years centered around the Earth. 1  We can only observe 13.7 billion light years of the Universe. 2  We are only able to see the parts of the Universe whose light has had time to reach us.
You, King Gelon, are aware the Universe is the name given by most astronomers to the sphere the center of which is the center of the Earth, while its radius is equal to the straight line between the center of the Sun and the center of the Earth. This is the common account as you have heard from astronomers.
