Scientist think our galaxy might be surrounded by a huge and empty void. Here's why

New theory suggests our galaxy could be surrounded by a void that is similar to an “air bubble in a cake’s air bubble,” as Futurism so poetically put it.

The new paper essentially suggests that the universe is expanding faster in our galaxy's vicinity than it is everywhere else.

This, the researchers say, has created a bit of a void around us, in which the region of space surrounding out galaxy rests at a lower density.
