The distance between Earth and the observable edge of the universe is 46 billion light-years. That's such a massive amount of space that it's impossible to comprehend. Some of the greatest minds on the planet are working tirelessly to make it possible for us to get to the nearest solar system–which is only 4.2 light-years away.

Kerbal Space Program 2 developer Intercept Games, believe it or not, is right there alongside scientists studying interstellar travel. It has been building a sequel from the ground up in order to make traveling across the universe possible in-game.

"One thing we're noticing, especially with the more advanced technologies in the game is that we're sometimes the first people to depict something because we're trying to keep abreast of the latest research," said Kerbal Space Program 2 creative director Nate Simpson. "Sometimes a piece of research will come very hot off the presses and we'll have to figure out what it might look like and our depiction of this thing is going to be the only one for a while."
