#2 And how they even know it is 5% we know + 20% dark matter, if you don't know the other 75%
If I give you a piece of a bar shaped cake, you never know how big the piece is in %. If you have not seen the whole cake.
It could be we only know 0.0001% and the universe is even more then dark matter, stars and planets

I like the idea of drawing the flow of a lecture but I feel like this one is a little unstructured, nothing like the http://www.snotr.com/video/8294/RSA_Animate_-_The_Divided_Brain Also, what's with the video's aspect ratio?

The percentage of dark matter and normal matter can be estimated by examining how much mass is required to produce observed results (such as galaxy rotation and gravitational lensing), and totting up how much of it is visible in any way. In that sense, it's more or less a direct measurement.
The rest, which most people call "dark energy", is a number spit out of cosmological models that need to account for the apparent accelerating expansion of the universe. You can calculate how much energy is required to drive the observed acceleration. And since matter and energy are interchangeable, you can combine the quantities to provide a total, from which you get the percentages.

Hence, "God". Atheism is an arrogant, concieted hypersimplification with no recourse to what we don't know and a sneering contempt in declaring that what we do know means there can be no One at the heart of it all. But then the vast population suffers from deep insecurity (inflicted by media and "education"
so you get the vast majority pompously huddling together to laugh down the equally ludicrous and insecure Christian Evangelist or "Muslim" extremist. Look, and think wider. Much wider. To think broadly and not in circles, you need to have an open door, and, as beautifully put by a great poet, they don't get there by themselves. Why must people stupidly and adamantly declare that if something can't be measured in some way, it can't or doesn't exist?

#9 Ignorant fools. I agree. I believe in his noodly appendages. All hail the giant spaghetti monster. ramen brother!
No seriously though. Atheism is "hypersimplification" ? How is that even possible to simplify something by choosing not to believe in the supernatural? To each his own anyways
