It is incredible how the positive and negative charges of the universe add up to zero and the gravitational spin of the galaxies add up to zero. I wonder if the theory of two "soap bubbles" colliding causing the big bang is true. This is because I think our universe came because of a collision with a positively charged and a negatively charged universe, which collided because their charges attracted them together. Now because they combined, that might be why our universe has zero charge, because the sum of the positively charged and negatively charged universes equaled zero.

I like Michio Kaku and how he explains such complicated ideas in a way that I can understand. I find the explanation about what makes up the universe interesting. That is that the standard model only represents 4% of the universe, dark matter 23%, and dark energy 73%.

I just realized that the first four minutes of the video have nothing to do with the idea that the "universe is a free lunch." This video is sort of like "Connections" where we know what the topic is but then he starts in a totally different place that no one thinks has any connection to the topic. But during the video, he is able to show us the connections from where he started in the beginning to the topic. So in the end, we find out how all this is connected to the universe being a free lunch.

The theory of "soap bubbles", like Siji said, is a little strange to think about, because the amount of math required to wrap your head is out of this world. Basically turning it into two magnets, with charges that makes them stick together, is optimal for kids to understand. Positive/negative charges of the galaxy add up to zero, the gravitational spin of ALL the galaxies do as well!! This was really cool. I liked how the person who made this video made it really easy to understand and to elaborate on. The universe actually might have zero charge because of this, but I could be wrong. The title of this video was kind of off-topic. This was really interesting though. I just thought of space as well---space. A big thing will floating colored heavy spheres, little white dots, and places where people go in a rocket to float around. I never really thought about the positive and negative energies of space much before. I didn't think it would be this complicated, but on the flip side, I didn't realize it would be that easy to comprehend. Dark matter and dark energy, I'm surprised, don't make up the entire universe. I know that might sound stupid to you people who know all that about space, but I'm not that person. I really hope that there will be further discoveries about not only this kind of stuff in space, but new planets, new life, and especially ALIENS. No, I'm kidding. Maybe I'm an alien... dun dun DUN!!!!

This incredible and crazy at the same time. 4% of the world is our universe of atoms. We are so different, form the fact that dark energy comes from NOTHNIG to dark matter being completely invisible and un-solid. Imagine going out of our world and into a world of dark matter and dark energy. And what about the soap bubbles/universes. Imagine our universe collides with another one, or it already has. It could cause catastrophe, or we could meet other life forms. This video was a 9/10, only because I did not understand the beginning part very well.
