What If You Fell Into the Biggest Void in the Universe

from What If: Science, Theory, and Possibilities · host What If

It's a place where nothing exists. A place without stars, planets, or galaxies. A place where you wouldn't meet a soul for hundreds of millions of light-years. This place is called the Boötes Void, or as I like to call it, The Great Nothing. Unless you find your way back to your ship, you'll be drifting through the perplexing dark of this mysterious nothing for billions of years. That is, your frozen, desiccated body would drift through this expanse for billions of years because there's nobody out here to retrieve you.
