Eventually, billions or even trillions of years from now, the universe is going to end.

Astrophysicists don't know exactly how the universe will end, but they have some ideas. A group from Munich called Kurzgesagt put together a video explaining the three most likely ways it could happen.

The problem is that the universe is expanding, and the rate that it's expanding keeps increasing. It's like throwing a ball up into the air and watching it speed away from you faster and faster.

This expansion is happening despite gravity doing its best to hold things together. That means another force must be acting on the universe besides gravity, and must be pretty powerful.

Astrophysicists think that force is something they call dark energy. Dark energy is invisible and we know almost nothing about it. But based on how fast everything is expanding, scientists think dark energy exists everywhere in space and could make up almost 70% of the universe
