Dark energy: the 68% of our universe

In the last post, we talked about dark matter. In this post, I want to discuss dark energy. 

Just like dark matter, we don't know much about dark energy. However, it makes up about 68 per cent of our universe.

Now there are a few things we know about dark energy. I will break them down for you.

As I talked about in my last post dark matter is present in the form of clusters around galaxies. On the other hand, dark energy is uniformly distributed throughout the universe. 

Another thing is that dark energy is a repulsive energy. This means it's like anti-gravity. Gravity makes two objects attract, dark energy makes them repel. 

Dark energy is the reason why our universe is expanding every second. 

Dark energy is both an amazing and an unsettling topic, isn't it?
