Dark Matter Facts Only 20% of all known matter is the matter we can see, or “normal matter.” The other 80% is Dark Matter, which is also around us just.

The invisibles of the Universe Dark matter & Dark energy

What is known in our Universe? https://www.youtube.com/watch?v=17jymDn0W6U Refer to Activity sheet Part 1- Activity 3 (step 2).

The known universe •Stars, planets •Galaxy •Galaxy clusters • • Is there invisible matter? Refer to Activity sheet Part 1, Introduction part (step 2-5).

Do you really know gravity? Universal glue Space Mass Bending Newton Einstein Refer to Activity sheet Part 1 - Background information and Activity 1 (gravity). http://wallpapersafari.com/w/NAUQsV

What is the Universe mainly made of? Refer to Activity sheet Part 1- Activity 3 (step 1).

Dark Energy •Invisible •Opposite of gravity •Only theories Refer to Activity sheet Part 1- Activity 3 (step 2).

Finding more proof of Dark Matter Solar system Galaxy Refer to Activity sheet Part 2 - Activity 1 (step 3-6).

Dark Matter •Invisible mass •Gravity for universe •Only theories of what it is Refer to Activity sheet Part 2 - Activity 2 (step 4), image of gravitational lensing. Then, at activity 3 (step 4), click to change image. Credit: NASA & ESA Credit: Nick Veasay
