It's possible that dark energy gained strength over time, which means that it would start to drive even planets away from their stars. And yes, you're right, depending on the very nature of space-time, it could be that this dark energy growing over time might rip the fabric of space apart. But Einstein didn't think about quantum mechanics and the general theory of relativity. When you unite them as string theory does, you get new things that space and time can do. The strings in string theory can surround the tear and form more of a band-aid. So it may not be as catastrophic as you think.
Neil deGrasse Tyson, comic co-host Chuck Nice, and theoretical physicist and author Brian Greene answer questions from our fans about string theory, the fabric of spacetime, interstellar travel, free will, and the meaning of life.
