Our Sun is so big that if you hollowed it out, it would hold 1,300,000 Earths.
If you hollowed out the star Antares, it would hold 64,000,000 of our Suns.
A star in the constellation Hercules is so big that, if hollowed out, it would hold 100,000,000 Antares stars.
The largest known star, Epsilon, is so big that if hollowed out, it could hold several million Hercules stars or 27,000,000,000 of our Suns.
Consider the thickness of a standard sheet of paper. Imagine that the thickness of one sheet of paper represents the 93,000,000 mile distance from the Earth to our Sun.
If every sheet's thickness represents 93,000,000 miles, how high would the stack of paper have to be to represent the distance from Earth to our next-nearest star, Alpha Centauri?
That stack of paper would need to be 70 feet high to represent that distance.
How high would the stack of paper be, with every sheet's thickness representing 93,000,000 miles, to represent the diameter of the Milky Way Galaxy?
That stack of paper would have to be 310 MILES high.
How high would the stack be if we wanted to represent the distance to the edge of the known Universe from Earth?
That stack would have to be 31 MILLION MILES high.
