String Theory and M-Theory

I found these video when hovering around the internet. Very interesting for me, but most people might found it boring. Highly recommended if my dear readers have any interest in these things:

• General explanation of the 4 known existing forces: Electromagnetic force, gravitational force, weak force, and nuclear force. About what is actually behind these forces?
• Quantum theories that you have never heard before. It is not in the text books because it is unproven and yet to be proved.
• Small things that inside quarks, which is inside the proton, neutron, and electron we know.
• Science friction things such as parallel universe and extra dimension.
• The theory that explains the universe itself.
• Possible explanation of the Big Bang.

Here's part 1, as an opening:
