You can’t write in space, not with an ordinary pen at any rate. There is no gravity to drag the ink into the nib. Astronauts have special pens for this very reason.

3.  Our universe has countless stars

Some scholars believe that there are 70 sextillion stars in the universe. That number probably sounds enormous but it is just a rough estimate. No one actually knows how many stars there are. The universe is a truly massive place.
