Lady Gaga

Lady Gaga, among other things, is the most followed person on twitter, with more than 10 million followers.
What if these people where actually following her, like walking behind her in a single file line?
Assuming that these people didn't want to invade each other's personal space, that line would be almost 6000 miles long.
If you wanted to drive the fastest car on the planet, one that goes 258 miles per hour, past this entire line, it would take you almost an entire day.
