So we know a few things now
Dark Matter is a positive force that attracts other objects with its gravity. On the other hand Dark Energy is negative force that that pushes galaxies away from each other. The fate of our universe is a battle between Dark Energy and Dark Matter.
Our universe is continuously expanding and not showing any sign of collapsing. So, Dark Energy must be stronger than Dark Matter at the moment. Now the question arises, will our universe ever slow down? To know that we have to figure out:
Scientists suspect Dark Energy might be the stronger force. So in the end Dark Energy will tear apart solar system, stars and eventually it will pulls apart matters, which is the fundamental block of our universe. And that will be the end of our universe.
