Question

The names tell the story: we do not see them directly. Yet, astronomers are convinced that they are there.  

Let's use the OBSERVE and MODEL dynamic to explain this.




Please address these questions:


1. What do we observe in the Universe that leads us to conclude that Dark Matter exists? Don't be afraid to list a few examples


2. Aside from knowing how much Dark Matter is there, do we know what it actually is?


3. What do we observe in the Universe that leads us to conclude that Dark Energy exists? Don't be afraid to list a few examples.


4. Aside from knowing how much Dark Energy there is, do we know what it actually is?


5. Regarding the expansion of the Universe, compare and contrast what each of these changes how fast the Universe is expanding.
