I heard in our Universe there is Matter & anti Matter.

Then there is Dark Matter.

Are Dark Matter and Anti Matter seen by Scientist?

Whare are they made of do they have neutrons/ protons/ electrons?

If not are they too made of Quarks?

Is Dark Matter and Anti-Matter simmilar?

Will Dark Matter and Matter Collide give out energy?

Will Anti-Matter and Matter Collide will give out energy?

Do Dark Matter has mass and gravity?

Do Anti-Matter has mass and gravity?
