The end of the universe
If universe has a beginning, it must have an end, right? I mean look at you, you born and you will die. There are 2 ways:
- The heat death- It states that everything will go sooooooooooooooooooo distant that the entropy would be zero and nothing will interact. And all will die. (More likely)
- The Big Rip- This states that everything will start to rip from the centre. The stars to planets to earth to humans to atoms to quarks. AMD dark energy will cause this. And that's how it will end. (Hoho, hollywood)
But relax you won't experience it anyways. 100 billion years to go bro.

Speed of the expansion
Imagine you throw a ball up in the sky, but instead of coming down, it slows for 1 sec and then shoots off in space like a rocket. What will be your reaction?
Scientists had the same reaction when they discovered that the expansion of the universe is speeding up very fast.
