Hi my name is Sally and i am going to teach you about Dark matter! When we finish learning about what it is we are going to make a prediction on what we think is going to happen next.
So, dark matter is something that takes up almost 95% of our universe but the weird thing is we cant see it. The only reason we know it exists is when we look at galaxies colliding. Let me call my scientist friend to elaborate on this idea.
Hi bill can you explain how we know that dark matter exists?
Of course I can,We know it exists by the way it interacts with light. Dark matter bends light when it is in high concentration.
Yes, the matter that we can see doesn't have strong enough gravity to keep galaxies from spreading apart so we can infer that there is another type of matter that we cant see.
Are there any other was scientist know that dark matter exists?
I cant tell you for sure but what i think will be the next steps regarding dark matter is that we will find out what substance, compound, and/or element it is made out of I thin this because it will allow us to understand why its gravity is so strong and why it bends light.
Thats so interesting, I have on question what do you think is next for dark matter? What do you think we will find out next about it?
we hope you guys enjoyed and learned something new!!
